2+ years later and yours is the video that has made the most sense to this new Vega 64 owner. Your approach of setting a fan speed first is simple genius and definitely the most sensible starting point for real world users. Thanks for the video!
I think it is simple, but most people seems to have problems understanding it, your tutorial makes it impossible to get it wrong. thanks for your excellent work, mate!
+Marcelo Tezza Yes, this was the intention - to start from basics so it's easy to understand.
I will keep it at 69 likes.

my sapphire nitro+ vega 64 bought new may 2019 ran like a champ above 1600 mhz core but started noticing lower clock speeds each driver updategot to update 19.12.1 clocks was only 1200 to 1300 mhz and losing 15 fps on valley bench updated to 19.12.2 the 2020 new driver and clocks again slower 1000 to 1200 mhz but mem stated bouncing from 800 to 945 which has never done temps fine edge temp only reaching 64 c . was afraid card was going bad . but uninstalled driver started going back to older drivers each time clocks would improve a little now back to driver 18.5.2 and clocks are back to 1580 to 1603 not the 1630 it was running but i know its drivers now not the card . i just bought this card 8 months ago new WHY is AMD doing this . if anyone having this problem with VEGA cards try this .. it stinks but it worked on my card .
@@stevin47 Mine also was running at 1600mhz when I bought it with the driver you mentioned and it also slows down with each driver update it seems. I think they do it so you will buy a new card. The only thing now is I really don't trust amd anymore. Why would someone spend so much money on a card if it's just going to be broken by drivers sometimes less than a year after it was purchased. I've had enough of them.
How many fps will i gain?
Don't forget that the Memory Voltage is actually some sort of vcore voltage floor. So your vcore voltage isn't going to go lower than whatever your mem voltage is set to.
+Adrian Mugnieco Yeah, found that info too late to put it in the vid...
MindBlank Tech totally cool, the hardware is still new. Content like this is why I'm subscribed!
I watched this video a few times due to my brains input lag. This is by far the best VEGA tuning guide on YT. Thanks to you I used wattman to get my V64 running at 1600Mhz @1090mv or 1560 @ 1050mv with a massive temp drop and a boost in frame rate with a custom fan curve. It's a shame how aggressive AMD are with their set voltages but I'm glad you helped me find the sweet spot.
Followed your settings with the exception of the fan speed (mine it's higher) and overall it is working like a charm. The temps have been reduced from 83-85c to 75-78 at max loads using the 3dmark time-spy benchmark and also got an improved average of 5-7 FPS with a rx vega 64 and ryzen 5 2600x 16gb ram at 3000Mhz. I'm totally chuffed about this, thank you very much for your technical explanations and the tweaks!
THIS IS THE _BEST_ VEGA UNDERVOLTING VIDEO OUT THERE!!!
+DCYOUKNIGHTED Thanks bud! :)
Good job man. In the end, Amd has always been a great experience for enthusiasts. There is always something new to discover and enjoy!
+thesilviu silviu Yeah, AMD usually needs more attention to bring out the potential. Been like this since I remember.
Memory voltage is actually the Core voltage Floor. even if you go with 1050mv and your mem voltage is at 1060mv it wont go to 1050mv it will sit at 1060. This is proven by Buildzoid so if you want to Undervolt make sure mem voltage is lower than your actual core clock.
TheSinisterEyes1 KANEKI!!!! U smashed !!!!
Thank you. Just bought an Vega 64. Was wondering why my voltage didn´t apply correctly.
This is not True. Core voltage FLOOR is not memory voltage. If it was Jan why didnt they named it memory voltage you dumbass. On my Chanel you van find a video dislrooves your illogic
Semiconductors don't behave like resistors, they don't have static resistance so no ohm law. Power draw increase/decrease in relation to voltage is calculated with squared voltages. 1.0V to 1.2V increases power draw 44%, not linear 20%. It's still approximation since it doesn't include leakage. In your example 156W power draw at 1.2V would drop to 108W at 1.0V. At 1.5V power draw would be 243W. And then frequency have linear effect on top of that.
You're absolutely right, sir. According to review on TPU, Vega's 64 average (gaming) power draw is 349W (turbo). Theoretically, decreasing voltage by 15% will result in ~252W of power draw. It's totally worth of possible performance (aka frequency) loss.
Kognak you're half right ohms law may not apply perfectly, and I'm gonna try hard to ignore the fact that he left the Ohms law text on the screen when he started explaining Watts law. Ohms law actually explains why the power consumption goes up by 2x the % increase in voltage he just messed up the math/explenation. Since the resistance stays roughly the same, when you change the voltage you have to balance the equation by proportionally changing the amperage. It's the voltage and amperage both changing by that percentage that results in double the effective change when you apply Watts. law.
+Kognak I'm far from an expert in this, but it needs to be relatable and easy to comprehend for people wondering what the hell's going on with "undervolting".
P=V*I, V=R*I, I=V/R so P=V*V/R, so here is your quadratic law. This is valid for the static power portion, where V is the core voltage and I the leakage current. The dynamic power is P=C*V*V*f, where C is the capacitance and f is the frequency of the GPU. Also, the more the active transistors the higher the power consumption (Vega64>Vega56). Finally, the static power dissipation, a result of existing leakage currents, rises with temperature, for this reason a proper cooling is extremely important, otherwise the GPU will try to get down the temperature by reducing voltage and frequency, resulting in a performance loss.
and it's not DC more like AC as Hz is referring to how many times i goes between 0 and 1. and this simple rules you are using are really not any god.. best regards 2.year electrical engineer student.
Thank you, thank you, thank you for explaining how to undervolt and overclock in a manner I could follow! Using what I've learned to adjust settings on a Nitro+ RX 580. Got it to 1450MHz and 1100mV and still stable. Not much different from out-of-the-box specs, but it's a start.
OK, so I've seen a couple of comments stating that I didn't perform a correct calculation of Power Draw when undervolting to 1.0v, since current draw also changes. Well, thing is that the purpose of this video is to convey in a simple-to-relate-to manner what's going on when undervolting. It's totally ok for pointing it out, but if we're to become over-zealous and turn this into an Electronics workshop (again, not the purpose of the vid), then I should've also accounted for the resistance modifying due to lower temperature, lower leakage, the fact that Ohm's law doesn't perfectly apply here etc.
Including the frequency variable (how it affects heat, power draw etc.) was as far and deep as I wanted to go on this subject.
Hope it's clearer now for those that obviously are more savvy on the Electronics science stuff.
Thnx for this excelent video, but there is something more that was limitating me to achieve higher core clocks: The GPU Hot-Spot Temp.
The problem was that while i was lowering my core voltage and rised my power limit, the delta between the GPU temp and the GPU Hot-Spot temp was higher and higher, at stock, the difference was around 20ºC (65ºC GPU and 85ºC Hot-Spot) but when i undervolted the GPU, that delta was around 40ºC over the GPU Temp, with a +30% power limit (60ºC GPU and 100ºC Hot-Spot temp) causing constant crashes after 1-2 hours of gameplay.
In the other hand i had to say that my GPU died the last week, i think that it came faulty, because that hot-spot temp wasn't normal when i was just lowering the voltage to 1030 mv in P7 (with allways the stock core clock). I never used more than 30% power limit and i never overclocked it. The model is the Gigabyte RX Vega 64 Gaming OC and im getting a new one the next week due to the great Gigabyte warranty.
A+ video, making the "big" tech tubers look like newbs. So with hbm2+core+fan what's you estimated total power draw after undervolt?
Yep, impressive how some youtubers are having a hard time getting it.
+Rex Tilton Thanks dude! Stock the PD was around 220W. Mainly because at stock it throttles, so it's below rated PD... After UV OC it's at 230W. So not bad at all.
I just put a reference Sapphire Vega 64 into my system, and started by setting the power limit to +50%, memory clock to 1050MHz, core boost clock to 1700MHz, and voltage offset (in Afterburner) to -100mv.
Under full load, the core clock stays in the 1680's. No artifacts or lockups thus far, though I've not yet put a great deal of stress on it.
Temperatures max out at about 20C over ambient (i.e. low 50's normally, as high as 55C at one point). Those temperatures are, of course, a direct consequence of the most important configuration option I chose, which was to remove the stock cooler and attach a water block instead.
Thanks for the guide. After tinkering around with my Vega64 I ended up with 1620Mhz at 1090mv on the core, 1030Mhz on the HBM, fan at 3700 68c max on the hotspot which is shown on GPU-Z.
nice
magnificent production and content quality!
+Mihai Balan Thank you! Appreciate it! :)
Guru3D sends greetings :D
Great Vid. im waiting for Vega rev.2 with 4xStacked HBM at whooping >1TB/s !
Some said av. q2 2018
Now on Fiji HBM with Undervolt ;) 1050 and 1.169v.
2 weeks bruh
Very nice video and explanation of how and what needs to be done. That +15% FPS is great btw. And remember that Vega drivers are FAR from optimised yet as with every new arch for AMD GPUs for the last 5 years at least.
Depends what after, if maximal performance, or balance in it and power comsuption. There was a dude on Techpowerup testing Vega in Superposition bench and kinda realized, that he founded the sweet spot at about 1300MHz on core with about 135W and 95% of performance (100% was reference balance mode with about 160W) or 108% of performance but with practically two times higher power hungry hog of 240W and it could be much more. :)
Thanks my build now runs better and a bit quieter. This was really helpful and awesome! Thanks a lot!
That is a really good job at describing undervolting. Well done
Soooo trying to understand the current 8 thumbs down on this excellent video that answered a lot of questions for AMD Vega 64 owners. This is the ONLY video I've seen that addresses some of the speed bumps for Vega and it was simple, and straight to the point.
ya
great explaination video. a much needed one also, as lot of people are really struggeling with the concept of undervolting. one little thing to correct though: you say some of the drawn power is converted to heat. that's not correct. ALL of the drawn power is converted to heat through heat radiation or friction/convection. even the air momentum and noise are converted back to heat mostly in the near proximity of the case.
I came here for an awesome video, and stayed for the science!
+Storm Jones Thanks mate! :D
Great video. Thank you for taking the time to explain this process in simple, easy to understand terms.
+michael gregory Glad you liked it, mate!
Really laid it out here! I'm going to revisit my GPU voltage/clocks and ensure I did it correctly!
Thank you for breaking this down when you didn't have to, subscribed, you're awesome.
A lot of people recommend to flash the Bios of the Vega 64 onto the 56 to get more voltage to HBM and therefore better HBM overclocks.
Joshbert & Friends I tried that yesterday. But for me, it didn't work out as good as I'd hoped.
With 56 bios, I have a stable 1000mv, ~1540Mhz core under load, 910Mhz HBM - at 2700RPM fan speed.
Now, with the 64 bios, the card got much hotter for me at the same settings, so I had to crank up the fan to 3000+ RPM. As expected, I did get better HBM performance (was it about 1000Mhz?), but the core clock was really unstable. Even though temperature kept below 80C under load, the core clock still never reached a stable 1540Mhz like before, but rather swung around between 1200-1350Mhz. So for me I got worse performance and more heat/louder fan.
@@amundskrullebakken8140 not all Chips are Equal some are better or worser you got unlucky with the Chip Roulette
Keep HBM under 80C for maximum stability, memory voltage is actually minimum core voltage, and some people seem to have an issue where if they mach P6 and P7 clocks they get locked to P5 so only adjust P7 at first.
+SlavjanA True, but very hard on reference cooler.
Got the same card as you! Best RX Vega 64 tutorial yet.
I got my sapphire nitro+ rx vega 64 undervolted/overclocked to 1715mhz core @ 1065mV and 1120mhz memory @ 951mV @ +50% power on air @ 100% fan speed for gaming purposes all stable. While gaming the core is actually 1650mhz average. This gained me 8-15 more FPS @ 4K in all my games. The hottest I’ve seen it get is 70c and I play in 4K max settings 60FPS. Average power consumption is around 300W.
Videos like this make the internet great! Awesome work and very informative!
Well done again ..... definitely not mind blank, mind full of good stuff hehe
Very good video. Big youtubers with all their fancy stupid videos should learn from smaller channels like this one doing all the good work. Its like the simple marketing philosophy. You go to a flashy mall, you get ripped of. You go to a small store, you get a bargain.
Even the fury cards did it. My Nitro R9 Fury wouldn't OC beyond 1075mhz, but it undervolted by -48mV and is rock stable.
Great editing, this is a go to video.
very great video just what i needes to get started with my new card
Awesome video, cant wait for AIB cards
Big like man. Appreciated!
Again a really good and informative Video. Thank you for the great content.
+Ole J Thanks mate and glad you guys enjoy it!
Thanks bro, nice guide
Thank you, very informative and useful. 🙂👍👍
I settled on HBM: 1000mhz, 1050mv. CORE: pstate6 1532mhz 1050mv. pstate7 1632mhz 1100mv. FAN: Min 2000 Target 3600. Power Limit 35% Temperature target 68c. It holds in the low to mid 60's and when It boosts, it's able to maintain my target temperature of 68c. I actually quit testing before it crashed but I do know my HBM won't hold at a 1000mv. I could try to lower pstate 7's voltage a bit more but meh. Also, you don't want to have your pstate voltage lower then your memory voltage. It doesn't work and you also don't want both pstates to have the same clock. It'll get stuck on pstate 5. Last thing... HWINFO64 voltage sensors make the card studder so disable those if you use that program.
Thanks for this MindBlank! Great guide as always!
So, what happens if you watercool the card? Would it operate at a higher frequency? Is there a frequency cap?
Thanks for explaining the concept. People just tell the results, so it's hard to grasp how to do it. I wonder what would happen if I tinker with R9 380 :)
+MrRaivokasMagma Yeah, that was the intention - start with the basics.
Very informative, clever man
as always a great video, thankyou again for making these
+zhain0 Thanks mate, I appreciate your guys' support!
keep up the good work ... :)
+Ali Naeimi Thanks mate!
Now if only there'd actually be cards available to buy. Not to mention custom ones...
PS: Looking forward to custom Vega roundup reviews, especially in regards s to temps/noise and tweaking.
Yeah, at ~500 euro that's a nobrainer to get a custom 1080. However, the latest Forza benchamarks seem to foreshadow the potential of the "fine wine". As usual, what we see in 2017 may be much more different than what we see in 2018...
very good video, subbing !
Math + Science = Fun and a loud fan ^_^
So, in other words, undervolt the sucker and tweak the fan levels to keep the card in check? Sounds like a normal day to me XD
Lowering your current will increase your current draw. Do not lower it too low, you will damage the electronics.
Good Video, I just dont understand what was the point of going down to 1000mV when you just a few moments later you pick 1100mV out of the blue.
So in simple words you say turn up the power limit and turn up the core clocks and the memory clocks lowing the voltage? And turning up the fan speed?
I wouldn't be surprised if a lot of the "hot and loud" problems AMD has always had was often at least in part due to their tendency to factory electrocute their processors. my Ryzen 5 1600 runs at higher than XFR clock speeds at 1V where the XFR pushes the voltages up to 1.4V if it is even running at its turbo speeds.
In your example you forgot that if you undervolt the current drawn will decrease also with the same load so no longer you are drawing 130amps but around 108amps.
I dunno but here are my results with Vega 64 AIO undervolt! Undervolting causes the Core Freq to increase by about 30 Mhz avg per -20mV drop which increases power consumption basically no change in power consumption from stock balanced its not till you hit around -50mV and under which drops power consumption but unfortunately this causes game instability and hard locks. All this testing is done at 60C as well. You are NEVER stable really with an overclock or UV unless you play games for months with ZERO crashes than you can say you have stability.
I can comment for the air cooled 64. I played around with it all day for the stable voltage at the 1546 average frequency. I started at 1200 mv and ended at 960 mv for p6 and p7 as well as the memory voltage (core floor voltage). Memory voltage is locked based on the bios of the card. More powerful gpus have more voltage. I added 100 Mhz to the memory to bring it up to 1045. I set the temp target so the max is 75 and the target is 70. The highest the fan has to spin up to to maintain 1546 Mhz average at 70 degrees is 2900 rpm. The fan noise is easily block able with headsets on while maintaining maximum performance. I tested Dirt rally to find stability and came to these results. (Dirt rally 2560x1080 2X Msaa average 121 fps minimum 100. Super sampling enabled in radeon settings as well as performance textures). I do have one question for you. How does the liquid version do at the dirt rally benchmark compared to the air cooled card I have? Does the higher frequencies help with fps?
Ryzen 1700 3.8 Ghz
Flare X 3200 Ram
Vega 64 @1546
Nope, 1 hour of gaming means stable for me. Because i don't ever play hours on end anymore, that was my younger days. So i could care fuck all if i crash after 13 hours of hardcore gaming, i don't do that. If i don't crash within the first hour, i'm good.
giantmonkey101 dude what is 60c referring to??? I’m lost
Excellent video, thanks for posting it.
I have the liquid cooled version, and I get some different results. In Global Wattman, I increase the frequency by 2.5% and set the memory clock to 1090. I set the fan at 80%. It runs stable, with the clock dropping to the 1760 range for brief moments. The things is, the card never reads hotter than 50c, no matter how much of a load it's under. Even with the temps running low, it still won't hold any higher of a clock. Does this sound right to you?
Everyone got better silicon than me :P I can only get to 1660 on p7 with the fan at max. Most of the time I sit at 1600Mhz which gets me around 1550Mhz stable with a fan speed of 3200 RPM. I could really do with better cooling.
You just forgot one step: change the stock Tim ^^
+Luís Pedro Yup, for sure. It's only that some manufacturers don't take well to opening the card up.
Yeah. Asus is one of them. I know that XFX doesn´t mind.
What's more power hungry than a Vega, my r9 290x
360w :)
Is your R9 290X overclocked? If so, what speeds are you running at?
Where can I download that WattTool software please?
thanks
So where you been MB? Haven't gotten a new video from you in a while.

I bought a Vega 64 Red Devil this month, I'm using the new 19.12.2 driver and had a performance improvement, but I had a problem in some games and others didn't even open. I'm still doing the driver tests, which one works best using undervolt. I particularly prefer the official drivers, I will test the one you quoted. As soon as AMD improves this new driver of it I use it again.
i have the same card as you sapphire nitro+ vega 64 and im seeing loss in performance too, older drivers are better than these new broken junk drivers, 2020 drivers suck for vega, i think october 2019 drivers had best undervolt and oc potential and mem oc, plus fans can run under 28% unlike todays zero fan that doesnt kick in even at 70 degrees because it buggy, probably last amd card i will buy
@@agreen9903 I'm currently using the last one that came out so far, which is 20.2.1. And so far it is very good and stable, even though I am touching the voltage curves, with undervolt in my Vega 64.
@@maurohos are you getting any crashes or black screens that require a forced restart?
@@agreen9903 So far I haven't had anything like it, The Division 2, Battlefiled 5, Dirt Rally 2.0, Metro Exudos among others and this driver is cool. The only problem I had was with the game DOOM and Need For Speed that no longer open, I believe that I will have to format the machine because I haven't done it for a long time.
I got mine running on auto fer GPU seen it 1835+ at times... The memory at 1100 didn't touch the voltage. +50% power limit on the gigabyte rx Vega 64 water cooled 😋
I paid 692 fer it @newegg -50 gift card because before I had rma'd the sapphire before it (and added $72) I caught them slipping with a new flash sale... So I got a free rosewill convection oven with the gift card. They owe ME .01 that's OK you can keep it Newegg lol.. cheers mates from the USA
It is odd. I ran into this trying to figure out why Radeon settings wiped itself out and would not install. It was some error, dont know. I did a DDU and I am good. But I did have to redo the settings for my undervolt. I let Tomb Raider DOX idle in the background while messing with my settings. The game maxes the gpu performance instantly, and does not let up. So my Vega 56 air boost with a stock MSI blower is working at a decently respectable steady 1605mhz on core clock with bursts up to 1643mhz. My current memory clock is 950mhz from 800mhz. It ran at 975, but I did not see enough gains to justify the higher temps. I have the wattman voltage for state 6 and 7 at 950 and 1080 ( ironically.) lol The memory is undervolted to 850. My highest temps are @72c at the worst and around 38c at idle. fan speed at an ear bleeding 3.2k-4.1k rpms sadly. The power draw is not really impressive at 220w under full load. I got a much smoother framerate in the vr games than I did with the gtx 1070 FTW edition I was borrowing.
This is very very useful so thank you, I just don't understand why this isn't done automatically?! Isn't this supposed to be a high end card? I'm getting 85c at Overwatch 1080p MEDIUM settings! It's crazy
That's beyond reasonable, if undervolting doesn't work I'd check the fan speeds and in an extreme case reapply the thermal paste.
Ordered strix vega 64 like 6 months ago and it was super hot so I opened it up replaced thermal pad and paste. Still too hot. RMA'd it and FINALLY today I got new strix card and guess what. All stock, I fire up valley benchmark and gpu hotspot rises to 100 celcius and soc VRM temp to 115 celcius max and fan speed sounds like jet engine. wtf.
Sadly the strix version of the vega cards have a very bad rep and apparently for a good reason. You want to stick with Sapphire Nitro+ or Red dragons from powercolor i think it is. Normally strix cards are working well but Asus really dropped the ball with the Vega cards.
you should post more often my dude
+Andrew Harper I know bud... It's hard with a new home in renovation and day job. You guys should see more frequent uploads once I'm moved in the new "studio". I'm working hard on everything.
There is no way in hell I can reach as good clock speeds as you @MindBlank Tech with my strix vega 64. I even changed the thermal pad to thermal grizzly and paste to noctua. I have to underclock AND undervolt to even have stable gaming experience. With these settings the gpu might be like 70 C, Hbm like 75 C and then the hotspot is 90 C. Without undervolting the hotspot is 100 C + and my games crash. I might have to run my card with these settings to be able to play games: core 1400 mhz, hbm: 945 mhz and hbm voltage at 1000mv and core voltage at 950mv. Idk what I should do. Its kinda annoying since I expected this strix card to be amazing... Many people can run their vega 64 at 1600-1700 mhz on the core and 1100-1200 on the hbm without problems... sigh
Great guide! One question, how do you keep the GPU under full load during voltage tweaking? Knowing I have one monitor.
Any tool you suggest?
Crater of Atom Download Unigine Heaven and run it in a window in the background. 👍
So if you want more performance you just have to overclock the memory?
Great job.Total System power?(Stock and U.v+O.c)
I love your accent man. That alone made me sub to you in firstplace, where are you from? I am curious, let me know! Also GJ with 3600 ryzen ram speed, thanks to you now many gamers realize that 7700k is slow. Did you check out AMD overclockers ram tests? From what i understood > 3200 timings matter again, for example 3200 CL12 in their test was faster than 3500 cl16. Will you test this once again? :)
Synoxia 7700K slow? It's only the fastest gaming CPU even over Ryzen. You sound biased. Pathetic biased AMD fans as usual.
Clayton Hernandez Pathetic Intel fan. 7700k is nowhere being the fastest cpu in gaming. Fastest single core cpu and most supported cpu is the proper position. Every game that support multithreads/ryzen or combination of both sees 7700k destroyed, which is the reason of rushing coffee lake (which is slower than ryzen, again)
Synoxia Oh really??!? Every benchmark I've seen has shown 7700K to be the gaming champ. How about you provide some links before posting this nonsense? I've seen countless benchmarks where 7700K came out on top too many times to count. Sure Ryzen wins in other areas but in GAMING, 7700K IS THE CHAMP.
Timings always matter mate, memory speed is a combination of timings and frequency, so memory at 2.6Ghz CL10 is faster than memory at 3.2Ghz CL20 for example.
Check this channel benchmarks then, fanboy.
Thermodynamically speaking, a graphics card is one big expensive resistor, since it does not transform electrical potential energy into anything other than heat, lol
dude u have the focusrite audio interface do u have problems with mic in csgo and crackling ?
Can someone tell me why my Vega 64 runs at 900mv without any sign of Crash? My HBM2 is also at 900mv. The Witcher is running at 75+ FPS and my GPU Is at 74 °C.
And my Fan is at 2200 rpm
hmmm luck?
I have some questions. I have a 600w 80+ bronze psu and a Rxvega 56 gigabyte double fan oc edition card paired with i5 9400f
Is the powersupply fine for this??
I'm also totally fine with putting the fan at 80 and 90% fan speeds and a little high temps, what memory and core clock boost max will be fine for me, please answer asap :)
Thanks for the info, just picked up a reference Vega 64. Sound is an issue for me. 2400RPM, 950mv across the board, 1020mhz on memory, set P6 and P7 to 1537 and 1547 respectively and it's stable at ~1450mhz automatically clocking. Average GPU power draw is 145W playing BF1 at ultra 1440P with FPS averaging at 95. Note this is on a 1600X 3.9ghz with 16GB ram at 3200mhz. Hope this helps, any advice is welcome as well. Kinda disappointed with games like Squad on UE4..
I may missed it. Its a Vega 64, isn't it? Good vid anyway
What's your final memory voltage? You forgot to mention!!
I am sorry, I know you probably did your research, but you are not right about (along with the power calculation, as allready mentioned) the lower HBM being hotter. I did a fast calculation and the difference is way under 1C. Sorry, but this is how thermodynamics work.
nice
how much power did you save in the end? :D
Undervolting reduces power consumption by how much in your case? im new to this pc building thing. thanks
Did you just say 130A? You do realize 1 Amp is a big number. The typical amperage of a wall outlet is around 10A. That's roughly 2000 Watts on 220V.
I think he means 1.3
@@samuelwhite3173 No, he means 130A. Power is current times voltage, so current is power divided by voltage. 130A at 1.1V is 143W. If you want to draw 250W at 1.05V, the amount of current will be 238A.
What games (other than witcher which I don't own) will keep the GPU at 99% Activity? And what software are you using to display the active temp and other info?
Just about any game should keep a GPU running 99%. Only games that doesn't is games like Warframe. That game doesn't utilize the GPU much.
What are you using to display the yellow writing which shows the Values in game?
Does the new auto undervolt GPU in Adrenalin 2020 work?
yes it works on my vega 56, it deducts 50mv from 1200mv
my gpu seems to be heat limit i under volted my rx 580 8gb and it been more stable
my vega pulse doesn't reach 70°C :D P7: 1650 and 1000mhz for hbm2
i have a sapphire vega pulse 56 i am getting some really great OC on it i would be very interested if you could do a similar review there is NONE OUT on this card showing any kind of undervolt oc etc...
Does decreasing the Voltage of the HBM2 matter? Do I need to lower the mv of my HBM2 if I found the max frequenty?
MindBlank will you be making a Vega 64 hybrid like you did with the RX 480?
+TopJoe 86 I will, but not a hybrid probably. I'm currently studying options available for Vega users interested in doing this.
MindBlank Tech Thanks for the response. I look forward to it.
I would like to see that
I got the RX Vega 64 OC Gaming (the one that has triple fans shroud rather than a blower). Would undervolting it improve performance like it does for this one? It's temp gets to around 67 - 72 degrees celcius though, which is why I'm not sure if undervolting will help or not.
It will help. Noise will be lower, temps even better, and more performance with less power draw.
I have a question. Ive followed this to UVOC my vega 64 and in games i get 1600-1650 pretty constantly but if i run a benchmark like firestrike it drops to 1400 in places. Any ideas why? It doesn't if i put the power limit up to +50% but then temps get crazy high compared to at 25% where it peaks at 50gpu and 60memory. tops.
So most of these problems are caused by the blower style coolers and may get better with aftermarket coolers?
I think what will happen is 1. driver improvements including uArch changes. 2. AiB cards will have better cooling so frequency will increase relative to voltage as well as noise levels reduce. Stock Vega is already hitting the heat wall. With better cooling frequencies rise = better performance overall. You can of course undervolt further to see slight improvements in frequency and less power usage but it will of course depend on how good your silicon is.
GN reportedly stated AMD are lying about Voltage (in these types of undervolt). He claims to have measured using a multi-meter the voltage and found it was actually higher (not what the software reports). Since you have an ability to explain these types of detail in more concise professional manner (abundance of sarcasm seems to be most important scientific methodology in GN content) it would be interesting to hear your thoughts on this, first about the possibility of this measurement and the readings (assuming that is possible to confirm).
Dobermanator I've got to defend GN on this one, he may be a bit sarcastic but his methods and understanding are solid. Where as Mindblank messed up the electrical explenation on undervolting pretty bad in this video. His explenation of how to do it was good though.
Well I've seen GN make a video review knowing (and broadcasting) he had a bad driver and other trouble which he was unable to resolve and then a fix came (turned out the very next day) GN did not redo or edit review. He chose time as the most important factor in releasing, that of course was used as fuel for an abundance of sarcasm going along with bad data - and him knowing in all that advance - so you think that's "solid," by all means go with that. And with all do respect I could not help notice that you have a similar style as GN. You've criticized in the form of sarcasm, and its is sarcasm because you did so yet offered no detail nor explanation of where or how it might have been better - at least here.
I didn't use any sarcasm. I criticized his electrical explanation which was wrong and I will explain since you are interested, and I said his explanation of how to do the undervolt was good, because it is a good method which should work. Sarcasm is stating the opposite of what you mean and since I meant both of my statements there was no sarcasm. His first equation is accurate ohms law, his second equation is watts law which is also accurate although mislabeled. He then gives a scenario a 1.2V processor at 130A with a power draw of 156W this would be watts law 1.2V x 130A = 156W. He reduces the voltage of 1.2V down to 1.0V and shows a power draw of 130W, this is where he messed up. As he stated earlier in the video your resistance is the factor in the equation of ohms law which is more or less constant so to use his hypothetical chip 1.2V = 130A x .00923Ω (I rounded the calculated ohm value for simplicity) updated for his new voltage value this equation would now read 1.0V = 130A x .00923Ω which would not be true he would need to adjust the amperage number in the calculation to re balance it since the ohm value is a "constant"(not truly constant but close enough as he explained in the beginning). so to make it right the equation should now read 1.0V =108A x.00923Ω(rounded again). Then applying watts law of voltage x amperage = wattage we get 1.0V x 108A = 108W.
Well thanks for that. I would / should have known that however I'm not often checking the math = the laws but good on you. Certain Mindblank would / should known this too, it's likely confusion as a result of all the other stuff he's trying put into this content = simple mistake, not from lack of knowledge. I do now, change the label of sarcasm to criticizing too as without the explanation (and it making sense *) it's not possible to know your intention. Regards to making sense, in this case it is an absolute because it deals with primarily
with math. With GN often sarcasm is merely that because its's often based (not always) on subjectivity or opinion that is not quantifiable despite claims / accusations made = my very original question above.
Steve Honaker II Sorry, GN looks like a child missbehaving when compared to mindblank, please, do not compare the two, one is a small channel with a very concise, organized and professional approach, the other is not.
really helpfull lol thanks ....
My water cooled vega 64 got 1105mhz at 950mv on the memory and 1672mhz on the core at 1100mv. Still have further testing to do though like I now the hbm can go lower still
Phillip Wise Sweet dude, good luck going further!
Phillip Wise nice that's what I'm getting from my 56 after bios flash and water cooling
ur not changing the hbm voltage. vega 64 always has 1.35v for the hbm memory. the number you change is the base core voltage, or floor voltage, which holds some parts of the memory management. you shouldnt go much lower than 950mV, this can cause instability. that number must always be lower than the "real" vcore tho.
Thanks for the info, i was getting a lot of instability under 920mv
