dont buy gddr5 gpus
vega 64 died on me after 1.5 year of mining. Unrepairable, These hbm modules are pretty bad.
TL:DR;
1. avoid HBM memory GPUs like Radeon 7, Vega, etc.
2. avoid GDDR6X memory GPUs like 3080, 3090, etc.
3. consider GPU fan can break due to running at 100%, can replace.
4. consider deep cleaning the GPU, and replacing thermal paste. warning: thermal pads, try to keep them.
5. cards got weird mining BIOSes, try to find BIOS for your model. warning: avoid high clock BIOS or wrong memory brand BIOS.
The problem is we never know who owns the cards, I have a 3080 that the memory doesn't go over 70ºc in the summer because I use copper instead of thermal pads
avoid gddr5

6. TL:DR. Don't buy ex-mining GPU.
Ahhh. That's better.
in the crypto crash of 2018 , i bought a mining Vega64 for 200$ , i cleaned it , repaste it . it ran fine until 2021 where i had a short circuit in the Vbios switch which made the car tetected as MI25 ( buildzoid helped me diagnose the card ). now the card is still runing well :D
Bought an ex-mining RX580 8gb for my nephew in Dec 2019. Being 1000 miles away, i made sure it was the Sapphire with easily replaceable fans. Sure enough, one died after a month. Seller sent him a replacement for no extra charge. Still running fine today.
Props to that seller. I bought a r9 280x long time ago. It ran well for 4 years and is now dead In a box somewhere. The fans on it failed after 2 years but replacements were very cheap.
Was it a sapphire dual-x? If so that could of been mine lol.
I bought a bunch of cards which included a HD 4890 TOP and 7950 Dual-X, both with fucked fans. Said 7950 has two Arctic P14's tiewrapped to it now lol
Hey BZ. Radeon VIIs perform like a 3080 when mining eth (100 mh/s) which is why they are such a good mining card. The algorithm for mining eth absolutely slams the memory controller and makes the memory chips hot.
VIIs tend to practically kill themselves while mining and give the generic error of code 43 when on a windows pc, overall they’re super delicate cards and I wouldn’t recommend buying one either
думаешь, он про это не знает?
Happy its not 42
That was my thought. On SSD's if you max out the memory, It will degrade fairly quickly. The principal should apply to gpu memory.
@@briankleinschmidt3664 No, Flash Memory is not the same as DRAM...
I run folding@home on my Radeon VII. I hope it isn't as harmful to the GPU as Ethereum...
Although I already had to "upgrade"the fans to Noctuas, failing bearings...
Good warning regarding the thermal pads. I remember destroying a used 4890 back in the day when I changed to an aftermarket cooling solution and lost 100 bucks. I can’t imagine doing something like that on a 1000 dollar card.
Totally agree on Radeon vii. They are old and have been mined on for a long time now. They aren't even reliable for mining, you can just turn the off and back on again and they get code 43 error.
yep, just like that :D
I replaced the thermal pads on my RTX 3080. When mining the VRAM was going over 105C and throttling. In equivalent scenarios I got a 20C reduction by replacing the pads and adding pads to the back of the VRAM modules and the backplate.
Also AVOID 3060 Ti, it has ongoing problems with Hynix GDDR6 memory failing, unless you're completely sure that it's not on Hynix memory. Media is somewhat silent about that, but some are already reporting about this issue, same as it was with early micron batches on rtx 2xxx cards couple years back.
Samsung or Micron are mostly fine
is it only 3060ti? Because 3070 uses pretty much the exact same memory layout
@@ThunderingRoar yep, but 3070 for some reason is mostly on samsung or micron, 3060Ti is mostly hynix for some vendors so it's the most affected. Regular 3060 uses 2Gb chips, so it's unaffected.
@@SovietN1nja how about budget gpus neither amd or nvidia i was looking for 3050 or 3060 or amd's 6600 do you have any idea what vram they use?
Is it all 3060tis or just some? Is there a way to tell which memory it has before buying?
Even before mining was a thing. The used video card market was full of cards with excessive fan noise.
Yea duh just reapply thermal paste and pads
All of your content is very informative, but the stuff I care about most is Watching you overclock current/last gen CPU/RAM/GPU, especially with all the random oc videos out there. You are usually the guy that actually knows the correct way to do things. Appreciate what you do, thanks.
A good way to get rid of cigarette odor on about any device is clean them as best you can and put them in a sealed bag or box with 2 or 3 drier softener sheets and let them set for a week. I don't know exactly how it works but it does work to eliminate the odor. Somehow the drier sheets will absorb the odor
not smoking in the first place works too
@@Jeter1230 Duh, the safest way to live is not to live at all, so what? I'm not killing myself.
Ozone machine. I believe you can go and take it to local places that have them for pretty cheap.
@@Jeter1230 I would assume OP was talking about getting rid of cigarette odor on *used* cards, not on a personal card.
@@phillgizmo8934 i mean, if we're splitting hairs here, by smoking you kinda are :P either way it's not like you can control whether or not a stranger on the internet happened to smoke while at their pc before selling you a used GPU
Also use "NVIDIA GRAPHICS FIRMWARE UPDATE TOOL FOR DISPLAYPORT 1.3 AND 1.4 DISPLAYS" on some older GTX cards, as they might give black screen under UEFI with display port cable, HDMI should work. Older CSM works fine.
Yep, had to do this on every 10-series card I owned yet.
@@Nighterlev checked the firmware tool out of curiosity after reading this thread, i was already running the update thankfully but i never even knew this was a thing
I want to say these thumbnails are lit dude, they go so well with all you do keep them coming!
Just a tip when looking for a defective GPU you might be able to fix: I'd avoid any RTX 3000 cards with "has video output, but can't install drivers" or "has video, but can't change resolution" or "not working properly, code 43 error in device manager". These issues are probably caused by one or more broken VRAM chip, broken/disconnected solderpads underneath one or more VRAM chips, broken or shorted traces from VRAM to GPU die, or defective GPU die. These defects are usually caused by a combination of heat and GPU sag, causing mechanical failure.
if you have a reballing die and a soldering station then many of those are quite straightforward fixes. for shorts just taking a few probes with the multimeter is more than enough.
@@baraka629Jesus Christ lol, what an asinine comment. If someone has a reballing die, soldering station, and the skill to reflow the entire thing, they don't need advice about this on RUclips comments lol, they already know this
I've always been suspicious of the reliability of the HBM GPU's. I guess I wasn't mistaken. It's probably the same interposer failure that plagued a lot of different chips in the mid- late 2000s, which is why you had the red ring of death issues with Xbox 360s, the PS3s yellow light and a lot of cards and laptops from that era are dead from the same issue, the die lifting off of the interposer and disconnecting.
interposer != substrate
@@Wasmachineman Yeah I get them mixed up a lot.
vega 56 original adopter and still runs , plays cyberpunk. to be fair I had a golden chip. my memory would oc high as well which is strange.
@@saraf01 Yeah I just recently upped from my Titan X I got a few weeks after launch in 2015, still played every new game I played on it fine at 1440p almost 7 years later, and still works wonders. 1000 bucks seemed unreal for a single GPU card back then, but it payed off in the long haul. I caved and got a 3080 when the prices became reasonable. I had a Radeon HD 3870x2 back in the day(2008ish), and it lasted about five weeks before it died, most other cards weren't much better then, maybe I just had bad luck with the silicon lottery.
@@connerstines1578 I was silly and bought the tesla version last month I think . still haven't got it to work , I think I need a K series Quadro for the extra support .
Excellent video! Been looking one of these!
Vega HBM gets mental hot, I'd hate to know how hot Radeon 7 HBM gets, plus HBM tends to get overclocked to all fk with no sympathy. Even GDDR6X gets as hot as the sun, that's why all these 3080s and stuff have memory sitting at 105c out of the box. It's not mining that kills cards, its the stupid heat these chips produce and card makers doing stupid AF cooling for them like 2mm steel mid plates to cool them. Meanwhile Polaris cards are how old? Mining just fine. My 290x 8GB been mining 24/7 since March 2017. Actually, I have had 2 cards with dead fan speed controllers, out of about 15 cards. Just put 2x 120mm fans on them and enjoy the upgrade
Agreed, 290/290X with reference coolers died like flies from mining as well back in 2014>2018. While cards with AIB coolers using the same PCB did much better.
Bullshit. Mining IS the thing that kills the cards. If they weren't used for mining, the memory would be fine.
@@liviuganea4108 mining is loading the card 24/7 vs gaming that loads the card for a few hours per day at most, but the problem is still that the heatsinks are inadequate.
If you were gaming 24/7 (in an internet cafe or doing rendering work), the cards would still die th same
@@liviuganea4108Let's hear all about your mining experience, how many cards you use, what type, how many died, in what way, what brand of memory etc.

Because answer is a scumbag does not have any integrity 🤷♂️
I dont need to have experience in stealing to point out someone stealing something.
Miners or better i should say, scumbags are reason for current gpu condition. Mining does kill gpu. Not because it runs 24/7 but because of process.
Be aware of scumbags trying to defend themselves and validify their action🤷♂️ and never buy from a miner. Their words means nothing, their whole identity is to ripoff others for money
Man, I HATE thermal pads too! But with this abomination design of 30-series cards from NVIDIA partners, getting a reasonably cool VRAM on a 3080ti or 3090 was outright impossible without changing the pads... And because of the shortage you couldn't just pick some specific GPU you know is built well..
I've lost count on how many times I've dismantled the cards to balance out the temps and how many different pads I've tried. Ended up with a soft gp-extreme pads of different thicknesses and got VRAM temps down by whopping 20C on my cards. Such a lazy design these cards are for such a crazy price tag, this is insane..
I'm curious what's waiting for us with 40-series and their power appetites. Current cooling solution they have is at the limit already.
I had to do the same as well on my 3080 ti from MSI. dropped my vram by almost 15c and the core went down almost 3c too.
@@DatzBunz In my case core temp actually increased by 2C, I suppose it's because significantly more heat started to go from memory into the heatsink. But core temp was initially low and it stayed low, so it was a good trade-off, I think.
@@Fiztex553 definitely normal and good trade off. My hotspot went up by like 3c I believe on mine. Had to undervolt mine as its really hot here in the summer time and man just a simple undervolt to it dropped temps like crazy as well. These things consume so much power for such little extra gains its crazy. I came from a 3070 ti and that never ran hot or used insane amount of power. Mainly went with the 3080 ti for the vram headroom but man I might do the opposite of most people and find a lower clocked vbios for it lol. My case too has like 10 fans too so im maxed on cooling ;/
@@DatzBunz Indeed, a proper voltage/frequency curve is a key in setting up the 30-series. One can end up with a boost frequency "overclock" which is actually hurting real life performance as the card starts to drop voltage and thus frequency when reaching a power limit. I'm doing VR simming, so I'm pushing my 3080ti very hard and I found that an effective overclock strategy is to find a lowest possible voltage at which the card still holds >1900 MHz on the core combined with highest power limit available on the card. This gives me stable performance with higher average fps and less stuttering in VR than stock settings, even though the boost clock is technically lower.
Imagine the lower end AIB GPU's. (Zotac, Inno3d) as example. Specially Zotac where the GPU design is even worst than the founders/reference. Cutting corners to maximise profit. They use the crappest materials and the most stone age power delivery design. Designed to run as hot as it can possibly can but still "good" enough to pass in QC.
Also the fact that the auto boosting behaviour push too much voltage on the card. When infact undervolting it made it run cooler + actually had a 1900+ MHz stable boost. VS the abnormal boost behaviour that overheats the zotac's and drop to the advertised 1700mhz
edit: the inno3d twin edge 3080's also are notorious for bad QC.
Some cards literally have a "hanging" cooler/thermal pads. Where even if fully screwed on, the thermal pad is stuck on the cooler's cold plate not even touching the memory chips.
Keep doing video's that are just you sharing a thought you had, and so it will allow the channel to have videos that we wouldn't always expect.
I think you called it on the Radeon 7’s, that sweet bandwidth for mining is the only reason anyone would buy them. The professional users who might’ve wanted them were better served by faster GPUs, and the only use for high bandwidth cards where core clocks don’t matter is ETH mining.
I mine on my GPUs and it’s only like 4-6GB of VRAM in use for that, so on an 8GB 3070 I’ve got enough VRAM leftover to watching RUclips in HD and play older games that would run on older 2-3GB cards. The only thing I do when I’m gaming and mining is flip my settings back to default from my memory OC, lower core clocks and undervolting.
Any of the Ti’s are going to be LHR models, so only the first run of non-Ti cards that were sold at the end of 2020 or early 2021 are more likely to be good mining cards. The LHR bypasses were only just released in the last couple of months or so, so don’t even worry about it.
If BZ says HBM cards don’t hold up to the heat or heavy use avoid those and 3090’s because all the mining forums are filled with guys having issues with 3090’s due to memory overheating issues and power draw.
My 3070 and an overkill heat sink on it so my memory is super cool, and the undervolting helps keep the heat down as well, so only thing I’ve put more wear on in any real way is the fans, but it runs silently most of the time anyway when it’s not running my custom settings.
If it runs and you get a good deal, then it’s a good deal, and you shouldn’t worry about it. If the cards were gonna fail from mining they likely would have by now, because usually it’s sketchy power supplies and janky setups that are more likely to kill the cards than the mining itself.
Only other thing I would look out for are used RX580’s because there’s a chance the VBIOS is modified and there’s a chance they fucked it up and if it wasn’t a dual BIOS card, then it might be a brick or it’s going to run like shit for games. I don’t know if other cards were known for running modded VBIOS, but RX580s were beasts with a custom flashed VBIOS.
Radeon VII's die for 2 reasons. 1) Cooked from high temps 2) The interposer from TSMC is notoriously unstable. The high temps cause the interposer to fail faster, so that's why mining kills them.
G6x does age incredibly quickly when held at high temps. Thrashing the G6x with activity pushes it's temps up really really fast.
the question is what are high temps? are they closer to the throttling temp (106 or 108) or is 100+ bad.
@@Nighterlev above 70 seems incredibly low for that to happen
I'd like to see some actual hard fact on the claim about the interposer itself. Like, the bottom chip in the first iterations of HBM got stupid hot, so who's to say (without taking shit apart and putting it under a microscope) that it isn't the micro solder bumps under the HBM that gives up the ghost?
What about memory degradation of chips other than you mentioned? I personally have exmining RX580 from previous mining craze and for a while everything was ok. Later memory started to throw artifacts from being worn out, and now only way to keep the drivers stable is no boost whatsoever on memory clocks and +30mV voltage.
The problem with VRAM on mining cards isn't just heavily reading and writing, but heavily reading and writing while overclocked and doing it for a long time, non stop. Just electron migration alone could potentially cause degradation and that's not to mention SMD wear.
No miner is overclockig cards. Miners strive for maximum power efficency which is usually accomplished with undervolting and undeclocking.
@@bariole Bullshit, the core may be undervolted and underclocked but the VRAM is likely overclocked and gets thrashed. It's obvious you've never mined ethe.
Great video, I appreciate the thorough discussion of this topic from an expert!
Second the advice about thermal pads. I had a hard time when I bought my 6800XT Midnight Black. It started crashing a couple months after buying (new but from stockx so no warranty). I saw that the fans were never ramping up with load, they were stuck at minimum rpm. So I disassembled the card, it was probably just loose header cable, but to be sure I also replaced all original pads by new ones using the best stuff available yes the high-K harder pads. That was a nightmare, now my fans worked but the card would shut down immediately if I launched any game, eventually it wouldn't even POST. I had to redo everything a couple times more until I got everything at perfect thickness including the GPU die (combining graphite pad and paste just like the factory build). In the end I got the card running cooler than day one thanks to better pads including lots in the back but not a recommended experience.
this sounds like you had a lot of fun with the card, feel ya man.
@@Heinz76Harald Guilty as charged a have fun taking things apart and tweaking them. But let me tell you the part that wasn't fun, the weeks between the first crashes and the final fix, when I thought that I had burned $1,3K at the time on a lemon card (bought from stockx so there's no return after just a week, and no warranty since you're not the original buyer)...
The suggestion of replacing dead fans with case fans or deshrouding is a great idea as well. Not only you'd get better performance, one would likely have to clean/replace thermal paste on the card anyway, so that's a good excuse to mod it for better thermals and noise.
As for the thermal pad argument, that's one of the main selling point of the "thermal putty" compounds. Depending on how pliable they are they can make a horrible mess but should be fine for thermals and won't be too "high" so putting mechanical stress on the board/solderballs/whatever.
Also afaik they are not that cheap. But they are easier to get than specific size/height/consistency of original pads
How hard is thermal putty? It seems to me it could still put stress on the card if it doesn't compress alot.
@@Magnulus76 it'll deform, but not in a temporary fashion like foam.
EVGA has the best warranty for 2nd hand market. so keep an eye out for evga cards which are still on warranty.
Depends which country your in, outside North American EVGA warranty is nothing special
Are you saying EVGA warranty still applies even if you are not the original buyer?
I bought a Strix 1080Ti from a miner some 2 years ago. Fans were fine, I replaced the thermal paste (which dropped the temps significantly) and it still runs perfectly.
Bought a ROG STRIX card as well but it was a Liquid Metal fail, was artifacting.
Cleaned that junk off which took a long time but same thing mines never skipped a beat in the 2-1/2 years I’ve owned it.
sadly is almost imposible to know if a card was on mining, so good luck to everyone who is planning to buy used this season. i got a xfx 5700xt raw II for $300 a month ago and im suspecting it was used for mining cuz the fans now have an awful vibration at 1600 rpm, a replacent will be good but theres no og or a decent review ones on amazon.
edit: im planing to do exactly what buildzoid said, even theres decent 4pin gpu fan to dual pwm case converters on amazon.
Ghetto modding even makes it way quieter, so...
bought a used 2060 and it has that weird noise as well but i think it was due to me ghetto cleaning it without airduster but otherwise it works fine
ghetto modding gpus is generally preferable to stock coolers because the 120mm fast are SO SO SO SO MUCH better at everything than those small flat gpu fans.
Im hoping rx5700xts and or 6700XTs get that cheap around here soon
Just dismount fans and oil them lol
I mined vega56 back in the day for 3 years without a single break, hbm and cpu temp never went above 60c, i sold them afterwards to a good price stating that they were mined, i even had logs of temps, and the buyer is still using it happily i think after 3 years. But it really depends on who is mining. I know lots of people overvolting and overclocking to mine, which makes no sense for the profitability specificly hbm based mem bandwidth mining and the lifecycle of the card will also degrade. So youll never know for sure
yeah, its a crapshoot. if you have free energy you just blast them at max power
There is no such thing as free energy. There is energy that someone else pays for you.

I had the mining bios thing happen to me. Bought an ex-miner RX570 that had a mining bios on in that the seller didn't tell me about. Spent a couple of hours trying to figure out wtf was going on (dont know why I didnt realize what the problem was earlier). After realizing why the fckin drivers don't want to install I quickly found the correct bios on techpowerup and flashed it and everything was fine (except the fact that the Strix RX570 is no strix at all. Asus just called it that and put a small ROG logo on it, but neither temps nor noise were good. Changing the thermal paste didnt achieve much (if anything). After a few months I got too annoyed and slapped a cheap AIO on it)
Agreed...those ROG Strix 570's were garbage. Final cash grab/GPU dump at the end of the first big mining boom.
had same thing with my 580 nitro+. Performance was different than what I saw on youtube comparisons. Changed bios and everything worked well after. I bought it years ago for like 125usd. They still go for twice that price (used) in my central europe country. I was happy when I heard the gpu prices fell, but I don't really see that here on used or new. My rx580 still works fine, thought one of the fans been getting louder. Right now I'm thinking about upgrading my display to 1440p along with beefier gpu. But I might also just wait for ryzen6000 laptops to fall in price or even build a 6000series SFFPC and sell my desktop.
@@BeHappyTo im in eastern EU. Got my Strix 580 for about €130. Prices skyrocketed, sold it for about €350 and got the 4gb 570 from my earlier post for about €90. Now I have my fingers crossed that second hand 6700XTs would hit ~€300-350. But as you said they still have a lot to drop. Cheapest I've seen is €400 for a low-end model.
I got a 580 from a guy who thought he bricked it by trying to flash a mining bios on it. He failed to put the mining bios on it entirely and never tested it as a primary card again.
@@BeHappyTo it looks like GPU prices have stagnated In EUropa since April. You can see this in the price history of many current gen GPUs.
Its like the inflation is increasing the price at the same speed as the crypto crash is decreasing it. WTF.
Happy with my ex-mining RX 570. The seller said it wasn't used for mining for very long. No idea how true that is, but I've had it since April 2021 and it's been brilliant. She seemed genuine enough. I did have to flash the BIOS, but that was easier than I thought it would be (hadn't done that before because I've never needed to).
My previous RX 570 and current RX 470 are both working great and were ex-mining cards. BIOS flash and a deep cleaning and they were as good as new
I mined with 3 Vega 64 cards. Two were the LE models with the aluminum air coolers, and one was the binned LC model. All mined for over a year at first. After mining, the two air cooled cards would not be able to hit anywhere near they rated frequencies even with thermals under control. It is possible these were defective from the get go. It was just never noticed since they were heavily downclocked and expierenced no 3D load until I tried to game on them. Or some part of the power delivery had degraded (shurg). The HBM seemed fine. The LC card has now mined for 18 months and is now gaming just fine in my son's computer. Just my experience.
If you have to replace the thermal pads K5 pro is probably the way to go. It's a pain to clean but because it works more as a thermal paste you're less likely to mess up and according to linus it improves the temperatures significantly. I used it on my laptop and it actually helped with temperatures but I missed some of the VRMs so I'd get bsods when gaming quite often so watch out for that.
If the fan on your GPU is giving out, it's a good time to refresh the thermal paste and pads. There are plenty of videos on RUclips showing you how to do this, including the size of the pads specific to your GPU. I've had the same 6 x 1070 ti's (18 fans total) mining consistently since 2018 and performed this task successfully a multitude of times.
Thank you for this video, it helped me a lot.
I bought a used 1070 fe when miners were dumping them after 20 series launched and BTC fell from its peak of $20k (I think it was at least 4 years ago now). It still runs great and even looks brand new, no signs of wear on the fan even. Buying it used worked really well for me since the previous owner took great care of it, but it is definitely very ymmv.
Wow some hot takes in this one! Case fans instead of replacing the stock ones. Interesting take. Not sure if I would agree in all cases. The thermal pad section in this is very overblown imo. I may not have replaced as many as you have but its been at least 20. I have never killed a card with thermal pads. The worst thing thats happened is some heat pump on the thermal paste on the die but its pretty easy to catch in time if you monitor temps. I have used thermal grizzly to the cheap soft ones to thermal putty. I have even messed up thickness by multiple mm with thermal grizzlys on 1080s and it just pumps the paste out, its never bent the pcb or de balled any cores in my experience. Even the hard thermal pads dont exert enough resistance to break anything even if you are a few mm off. It wont run for long but its not like immediate death. And getting the correct size pads takes 3 seconds with a good measurement tool.
My avoid list is very similar.
Anything interposer (fury, vega, radeon 7, titan V)
Anything polaris x70, x80, x90
Anything RDNA 1 (rx 5000) with more than 4GB of VRAM
Anything GDDR6X.
Polaris and RDNA 1 cards were popular with BIOS mods that improve mining performance but harm gaming performance. It can be a headache to deal with modded cards, plus they've been in the mines for a very long time at this point.

I haven't had any problems with any Polaris cards that were mined with..... aside from the previous owner not reflashing the correct VBIOS back on to the card.
@@m8x425 Yeah, for technical people who have a fallback display output to be able to correct a bad flash they can be a decent buy. The problem is they are still outrageously too expensive. They're selling for like $150 for a 580 8gb and that's more than double what I'd even remotely think of paying for one.
Basically don't buy ex-mining GPUs, unless you love gambling.
@@cracklingice Yeah, that's a bit high. There are people selling them in my area on CL or Offerup for $120.... but I've seen people selling FTW3 1080ti's for $300.
I think it was back in 2019 I bought an 8gb RX 480 Strix for $90, a group of the Sapphire Nitro+ (light blue shroud) 8gb RX 580's for $100 a piece. I'd also seen RX 570's listed for $60 back then.
Very helpful, thanks!
so much useful information in tthis video, thank you so much.
Hi Buildzoid!
For the thermalpad-replacement you can go with thermal putty (stuff like K5 Pro). Tested it on Laptop and Smartphones and it works like a charm.
They're quite messy tho. I'd rather get some decent soft pads from Alphacool.
It's funny, I thought about this topic the other day, if I would have a problem with an ex-mining card and now you made a video about it.
Thanks for the insight
Great video ! What's your opinion on manufacturer OC cards, like the MSI Suprim 30 series ?
Thanks for all of the infos.
The problem with case fans is that they usually have a different connector. You either connect them to the motherboard and lose the fan curve defined by the GPU, or have to get the right connectors and solder the fans to them.
Great vid bro this was needed pity you did not do part two on Ebay second hand I like you have bought many parts second hand on Ebay with very good success
I've bought used mining cards from fleabay since4 2013 and resold them during mining peaks and have had no regrets whatsoever. I never had a failed one.
I look for those that have had been bios flashed for undervolting.
How do u look for those that have been undervolted? Do u just ask the seller?
absolutely agree with replacing fans with case fans. Did that on my 1070 in the past and it gave a good performance boost besides being more silent. Just used cable ties to strap them on, perfection!
How did you deal with powering and controlling the speed of those case fans?
@@SylvanFeanturi had the case temp sensor attached near the card, the fans attached to the motherboard and set a fan curve for case temp. Works like a charm.
@@yspegel Okay, thanks for the tip! May do for something like that if I don't manage to get mini pwm -> pwm plug on a cheap :D
Hi guys, so getting mining 6900XT for $550 is safe & good deal?
I just bought an MSI 3080ti gaming x trio from ebay. Not in original box. So far so good. Runs very cool. No issues following a lengthy stress test.
I have purchases used, 3090 used for mining for 1 year, I take the cards to clean and replace thermal paste and thermal pads, twice we reopened the card to solve hotspot issue where the card have issue that it reach up to 105 ° C and thermal throttle is there a way i can solve this issue ?
Thank you for your video. 👍
Whats your opinion on thermal putty? They typically don't have that good of a conductivity but it eliminates the chance of killing your card
Awesome, thanks for this.
thanks for this video!
there are literally piles of ex-mining Vega 56 being sold for 170-220 usd in my area, I almost tempted to get one, but I guess I'll look for something else
The cards would run fine. The problem is that Vega56 performance ain't worth ~$200 anymore imo
More like $100...
Does the memory type Samsung/Hynix vs Micron bios types apply too all GPUs so all Radeon and Nvidia or just RX580 specific?
very good info, thank you
What about capacitor degregation in mining cards?
@Actually Hardcore Overclocking. Question - What would be a way if a video card is not detected in device manager?
BZ, u said u need to keep an eye on 3 things when choosing a bios for ur gpu, but u only stated 2, clocks and memory brand. Whats the third one?
hi would you consider working on my SPECTRIX D50 Xtreme DDR4 RGB Memory Module
I have 4 of them, but the led's are busted on 2 sticks of the 4. wondering if i could send them to you
Thanks!
Could you include chapter marks, would make it easy to jump to rants/topics of interest! Thanks! 💙
What about mining gpus with waterblocks, do the vrm suffer that much? Either the memory or vcore vrms
now i want to see your case fan gpu mods
I bought a renewed 6700Xt powercolor from Amazon... How do i know if it was mined??
I replaced the thermal pads on my gigabyte card because the stock pads leak oil from normal use and have trash cooling peformance as well. I used thermalright they are a bit harder than stock. But what I did was heat up the gpu before reassembling it to make the new pads softer. Memory Temps dropped massively and no negative peformace on the core where I used noctua nt-n1.
EVGA pads on my old 1070 did that as well. Scared the crap out of me.
So far I'm 0/4 for working 2080 Tis from EVGA B-Stock, all have had green or purple artifacting, Code 43 errors, and low resolution only output.
the price of Vegas is higher than the 1080 because they do 50-55mh on eth instead of like 38mh
same idea with the VI, it does insane hashrate on eth (but will up and die if you fart near it)
17:18 Regarding the nicotine dust and residue that is on these parts, I recommend cleaning giving it a brief once over to get the thick parts of dust. Once that's done get some CRC Electronics Cleaner (other countries might have different brands). That stuff has a powerful spray, dries fast, 0 water, and will strip the stickiness away. If it's extra stubborn, you can spray a q-tip or something and quickly rub the area.
CRC makes some excellent products for automotive too!
What about the thermal paste k5 pro for vrm? I mean no tolerance issue there
Recently heard from Steveon Gamers Nexus that apparently RTX 3xxx cards especially the high end can have transient spikes of iirc around 700 watts. Which is a good indication on why the vrms are exploding on 3090s.
I've found the tar from smoker's computer parts is far more of a problem than the smell. The tar forms a sticky surface to which the dust adheres. The Datavac won't touch it so you have to resort to lots of IPA and cotton buds.
please recommend good thermal pads.. recently bought gelid and thermalright but they were rock hard, with zero compressibility and cracked like crazy after 6 weeks.. a bit lost now as used these for years but seems the quality has gone south :-(
I bought an exmining RX580 in jan 2020, and its been solid. I even mined on it last winter since I was paying for heat I might as well profit from it. It was a wash with crypto crashing, but thats absolutely fine with me since now GPUs are becoming normal. Still this old card marches on.
whats the best beast card over 1k to game 1080p ultra
Be wary of 3060ti (both used and new), as they almost always use Hynix 1GB GDDR6 chips as of late and those die from a slight overheat.
And the only way to fix them afterwards is to swap all 8 chips of VRAM for different vendor like Samsung. Becasue while you use the hot air gun to swap 1 chip, all chips around it die from that.
my 3060ti's do much better than me. i cant sit in the room for long.
All the models of 3060 ti?
Is this all model of 3060ti
@@alfredgamerzzgamers3970 no not all models.
Also, if buying secondary, ask if the warranty was used. If the card wasn't registered (except evga) get the receipt. I did some mining and changed all my pads and paste every 3 months and cleaned them weekly. It takes minutes to blow out a rig with a blower.
@Buildzoid Have you tried CS Labs K5 Pro thermal pads replacement? I love it. It dropped my GPUs Hotspot Temp by 15c. It's a little messy but worth it if you match the thickness and it spreads out when pressure is applied.
Came to the comments to ask about this. Saw an LTT video about it and it looks like a much less stressful solution
@@Wiikender besides the mess it's a great product. It was $30 for 6x10g bottles.
Well where would i get a new board for the chip even if i buy a used chip. Never seen them sold separately.
Thermal pads; Gelid Extreme and Ultimate are soft (they're more like pre-formed sheets of putty - you can ball them up and use them as such) and amongst the best thermally (ahem, and the most expensive). I've replaced every pad on every component over the past few years (two MB's and four GPU's) with them. With GPU's I always disassemble again after fitting to check I've got the thicknesses right (having measured everything the best I can, clearances/gaps or the original pads). Temperatures _always_ drop markedly, if there's no sensor a finger test confirms the heatsinks are always warmer.
Was waiting for you to say something about buying used GPUs, thanks man!
About the thermalpads issue: there is also those "thick" paste solution. Should this be doing the trick without risking damage due to hardness and thickness?
I have a Inno3D 2080 whose fan headers are blocked at maximum speed. This happened most likely because I changed the original 2 fans for a 3 *Noctua 92x12 setup using a splitter for one of the fans. The amperes shouldn't have been a problem in theory as the original fans had three times more Ampere capacity, but something went wrong I guess.
I am currently powering my GPU fans from my mainboard, but was wondering if anyone has encountered this issue or if there are any fixes for the GPU fan headers.
Gpurisers has 20W/mK pads that are soft and work super well. Kritical pads has kits with precut pads for a lot 30xx cards. Haven't tried them myself but I suspect it's the same material as gpurisers
intresting I might check those out.
@@ActuallyHardcoreOverclocking I can't vouch for kritical pads, but iirc gpurisers has a UK warehouse. And gpurisers pads come in 0.25mm increments.
Bought a MSI GTX 1080Ti Gaming X back when the crypto bubble burst a couple of years back from a miner for around 220-250$. I cleaned it (even though it was pretty clean), changed paste and thermal pads (did research for the right thickness) and it still works flawless to this day. Hands down the best buy I ever made for my PC. I finally replaced it with a new RTX 3080Ti I got cheap. Maybe I was lucky.
I've mined for over a year on my 5700 XT. It's on an EK Quantum Vector, it runs at 794mv @ 1396MHz. It's on a custom BIOS with tightened GDDR6 timings that is suitable for both mining and gaming, and the timings even boosted FPS by about 2.8%, the VRAM runs at 1800MHz. Max core edge temp while mining is 40c, TJ at 46C. GDDR6 temp maxes at 55-58C depending on ambient. VRM runs at 42C. Eth hash is 56.12MH/s at 95 watts.
If someone offered me that kind of information about the card I was buying, I'd buy it without a single second thought. I'd also have zero questions about reliability about buying my own card. In fact, I'd be even more willing to buy a card which was mined, especially if temperature and power metrics were given, because chances are higher that the card was mined on than not, and if they're not upfront about it, then it was probably ran hot and carelessly.
I bought an rx470 that was mined on for 3 years, and I have daily used it as an htpc/gaming card for the last 3. Minus having to reinstall drivers every other update, it just needed repasted. And the fans needed replaced, but it was an xfx card with easy swap fans. Hindsight says I should've bought one of those 2x80mm fan bracket things off Amazon for 15$ instead of 15$ a fan for replacements.
I found it incredibly funny when you were repeatedly warning against dead Radeon VIIs. :)
I'm looking at a 2070super is that decent?
Should I buy an mined a5000 instead of a new 4090 for rendering?
Don't buy any. Let the prices fall even further 😎
I deal with a lot of used parts, in my experience the best way to get rid of bad smells like cigarettes is with an ozone generator. You can buy a good enough one off of amazon for $60, chuck it in a cardboard box with your stinky stuff for an hour or so and it'll take the smell out. It'll smell like it's been sterilized for a few days but afterwards will be scent free.
I see a lot of BIOS failures on Vega cards as well.
Does the oven trick do anything good to dead radeon 7s'?
no, ofc
I bought two ASUS Strix 3090 recently on ebay for much less than they usually go used. (800€ each)
The seller didnt mention any mining on them, but he was selling three of them of which one was sold already, so i got the remaining two.
The only thing he mentioned was he was using it for CAD. He is the owner of a shop for doll supplies and toys, oddly enough.
He also mentioned that he changed the thermal paste and pads.
He also was selling a couple of powerful PSUs, a rather weak CPU and a metal shelf on his Ebay shop.
The cards were in quite a pristine condition tho, very little scratches, very little dust. The fans are not rattling. Heck they still even smell new!
BIOS seems to report correct informations, tho the BIOS switch was flipped to Performance.
The only thing really weird about those cards is they get hot quite quickly. I run Furmark on them for like 40 minutes and they got to a toasty 80+C but remained there.
HWM reported hotspot temps of about 100c tho.... But no artifacting or anything and 3DMark score is around 19k for GPU score in time spy and around 13k in Port Royal.
I'm just wondering if this is normal behaviour? IDK how to tell if they were used for mining tho, are there definite tell-tale signs that are easy to spot?
A GPU fan modding video would be interesting
Is it though? It is literally just taking off the old fans and zip-tying new ones on.

Yes, of course. This way there will be so many people trying the mod and fail. Then I will have more clients and of course I will ask for double the price I am asking from someone who is coming to me to do it professionally and not trying to do it themselves. I barely can't wait.
@@Dandan-tg6tj Easily i can find a lot of videos of random dudes killing her gpus aplling tthermalpaste using dot method. In fact users cant be underrated.
This was one of the videos I watched to get info on used cards while I was shopping around for used cards over the last month or two. I eventually bought a used EVGA FTW3 RTX 3080. The transferable warranty coverage which EVGA offers gave me more piece of mind, as does the fact that the card has two bioses, and, of course, it also has a better than normal cooler.
I also watched Buildzoid's teardown video on the FTW3, and I realize that the components used and board design was disappointing to a lot of people, but for someone who doesn't want to do anything more than occasional light to moderate overclocking at most, it seems like a great card, especially because I didn't have to pay a price premium for it over other used RTX 3080 listings (I paid about 580 USD including shipping).
I'm still not sure if it was the best choice, and I'm not all that impressed by Ray Tracing, but at least I'm not too worried about the card actually dying on me any time soon. I probably should have just forgotten about Ray Tracing and gotten an RX 6700 XT.
Btw for some people information. At least there are some news about that from Russia.
It seems that miners created burn-tool (basically shorted PCI-E riser, or one with swapped lines). It is to attempt to RMA GPU to either seller or manufacturer.
So markets started to decline more GPU from warranty repair than usual, and you may find one of these in wild (aka ebay, aliexpress or local markeplace).
Is it worth getting a 6600XT used over a 6600 new? The XT is cheaper but used.
