I feel like you gave us more with that CPU then you could have ever done by giving it to just one person. Free stuff is cool and all but I watch your videos for the knowledge. Means more to me then money.
Well said. This was very entertaining
Bruh... you seek knowledge then misspelled a word.
@@AMSOfficial79 😂😂😂 in the same sentence
@@AMSOfficial79 bruh... you seek bruh... but you misbruhed bruh
well put!
Extremely impressing! I would never have thought that even a modern CPU would survive these voltages. Shoutout to the engineers and manufacturers for building such *hot* shit and to you Jay and your team for showing and proofing it in such a entertaining way!
The result of Intel 14++++++++++++++++ nm ;)
Surviving it for a very short time and more than a few days run time is completely different
Cpu's dont die from voltage. Since in this test the CPU was throttling, adding more voltage would drop the amperage, meaning the total amount of watts going through the CPU is constant. CPU's can easily hit 1.6v on low loads and survive for decades. Actually, a stock 10900k with TVB enabled hits 1.65 from the factory.
Regarding this test, if he had better cooling and could keep it from throttling, the CPU would probably instantly die at 1.65-1.7 volts running cinebench
@@KiSs0fd3aTh low, single core loads are completely different to sustained all core loads. And CPU's absolutely do degrade and thus die from voltage. Derbauer did a test over 6 months with ryzens, 2 degraded noticeably, one didn't care and that was only at 1.45....granted that's for ryzen but still
He also did degrade the cpu significantly running this test.
I used to use an AMD 233Mhz, I had it sitting in a box under my desk. Fast forward a few months later, I accidentally touched the case (one of those old, solid sheet metal ones), and the whole case was really warm to the touch. I crawled under my desk and I realized that the whole area (it sat in a corner) was actually really warm. Come to find out that the fan on the cpu cooler had died, and the cpu was basically using the motherboard and by extension the whole computer and case to cool itself. The heat that came out of the case when I opened it was incredible. It was still running though, I was really impressed with the chip and the Asus P55T2P4 motherboard for lasting all that time. The fan had probably died at least a week prior to me discovering.
"back in the day" I built a K6-2 233 for my family (I was 13 or so and really getting into computers) and I had no idea but when I built the PC I set the CPU voltage for old Intel specs which was 5v. The case of the computer was quite warm (and the heatsink and fan was blistering hot). I later found out about a month later that the CPU uses 3.2v and I went back in and changed the jumper, much cooler! I was surprised the CPU survived. I felt kinda dumb, but I learned.
And that's why folks, the CPU is one of the most resilient components in your system 🙂
My cpu survived a motherboard dying and a power supply breaking on seperate occasions. Totally unexpected, but a blessing. The damn beast is still running. She be scarred, but still is a fine lass haha
@@liveyourdreammedia My 6600k has been going for over 6+ years at a comfortable 5GHz - 1.4Vcore on an Asus Z170-A board, I'm super impressed how reliable my PC has been, my HDD indicated 27,000 hours of power on time which is around when I built it.
@@Gobbbbb that's great dude!!
still runnin a 2600k in my secondary system@ 5.1 :D and 1.35voltz :*
@@tyonorshapzc7tjfvb7-caz if you're stable @ 1.35 it's not a gold sample, it's a rhodium sample
Let's all appreciate the engineering that allows this kind of abuse to occur and still result in a more-or-less functional CPU
The CPU hotspot, you mentioned (removed heatsink, and cooked CPU) was back in the day, when not thermal throttling was implemented in any CPUs, whatsoever. (an external temp sensor was usually in the middle of the 370 pin socket, but that was mostly optiona, and only shot down the system, when measured too high temp.
This test was one of the reasons, thermel throttling has been added to CPUs!
I dont think, currently, you will be able to destroy a CPU.
There are basically two ways, they can die:
- Thermal degradation
- The gate oxide is damaged due to too high gate voltage (the Vcore, you fiddled with...)
Thermals:
Heat generation of a semiconductor has two aspects:
- Clock speed: th number of times the given circuit changes state
- Supply voltage: The voltage provided to the circuit.
In general, heat generation of the chip is proportional (linear) to the clock BUT exponential to supply voltage.
This means, that if you want to stress your CPU because of heat, its better to increase Vcore voltage!
For thermal degradation:
Semiconductors are manufactured by some metallurgical processes, that are mostly temperature driven. The silicon wafer is doped with different substances to create a P-N junction. The higher the temperature, the faster the reaction is...
But usually, during manufacture time, these temps are way over a 1000°C. At this temperature, those reactions take a couple of hours.
Since those reactions are activated by temperature, the Arrhenius equation applies to them. That states, that each 10°C raise in temperature halves the reaction time. SO every 10°C decrease in the ambient temp reduces the propagation of this reaction by half.
And there is a lot of 10°C degrees between 100°C CPU core and 1000°C
That means, if you want to destroy your CPU by temperature, you need either a high temperature environment, or a lot of time.
For Gate oxide damage:
Gate of MOSFETs are like a capacitor.
There is a Gate electrode, an insulator and the actual channel below.
Electrons are attracted by the gate voltage from the channel to the gate electrode by the gate voltage (Vcore) .
Normally, those electrons only pile up in the Channel, and provide a conductive path between the Drain and the source, so the MOSFET is opened.
In case of a too high Gate voltage, those electrons move from the channel to the insulating Oxide layer and mostly stuck there, and ruin the insulation properties ( like stones in a stream, where you can step on them to cross it dry footed)
(This means, that this specific MOSFET might open with lower Gate voltage ( In an extreme case, it will alwasy stay open...)
This is of course not a clear yes/no situation, so total loss of functionality only happens, when critical MOSFETs in the design are demeged permanently.
Until that time, the restarts are the common symptomes of this issue.
So, conclusion is:
- I am not surprised, that you could not destroy the CPU.
- However, it is clear, you reached some of its limitation!
- To really destroy the CPU, you need more Vcore voltage OR you need to run the CPU for MUUUUCH longer time...
- But even then: destruction of a single MOSFET within the Billions of transistors in a 9900K does not mean automatically, that you "killed" you r whole CPU...
It will most liekly result in such wacky operation of it...
bruh get a life.....
Yea, electromigration is the real killer of CPUs. The higher the voltage, the more this effect can become a problem. It typically is the result of running cores at very high voltages for extended periods of time, it usually won't destroy a CPU right away. Instead, you'll have a CPU that runs fine for six months or a year, and then starts to become unstable. At the voltages CPUs ship at, it's rarely an issue.
CPUs are also manufactured to be able to briefly withstand VERY high temperatures when they aren't being powered (upwards of 200-300C) during the soldering process. It's not necessarily the temperature that kills them, but rather running them at these temperatures with power going through them. The real temperature at which CPUs fry themselves while running is around 110-130C, and hotspots between the many sensors of the CPU die do exist. But with auto shutoffs happening at 100-105C, it's not really much of a risk. The CPU will shut itself down long before there are any problems.
@@photoniccannon2117 CPUs are manufactured at over a 1000°C temperatures. Mostly metallurgic steps are taken during the process. When they are "finished" those processes are technically just "frozen" not stopped. Since those are temperature activated reactions, the lower the operational temperature, the longer their lifespan would be. Since even the 100°C is way lower than the 1000+°C used at manufacturing, this difference is practically unrecognizable for a normal user.
regarding electron migration, this is why alumínium was changed to copper in the process around 2000. Alumínium atoms were too light so the flow of electrons could push them away and break conductive paths.
Cool exploration video, but multimeters are not good at all to measure voltage fluctuation. You should get an oscilloscope to really see the min/max voltage.
The video wasn't really about that.
It served the purpose in this video just fine, but you are not wrong, they don't have the refresh rate to show what is actually happening, especially the el cheapo model he has.
@@BlacKSye yeah, I know. But it might be misleading to someone. Also, the peak voltage could been even higher and it was just not picked by the multimeter.
You underestimate how quickly a multimeter will adjust to a change in voltage, and how much they will adjust by. They absolutely will detect a 1mV adjustment without issue within about a quarter of a second. For this video, that is more than sufficient.
@@AZSprocket you actually think 4hz refresh rate is enough for something like this?
Laughable
JayzTwoCents: I know what you're thinking. "You're wasting CPUs."
Meanwhile, me: *PROCEED WITH THE DESTRUCTION*
I imagine you like that scene of the first Incredibles movie.. where EDNA MODE shows the super suits for the family to the completely worried elastigirl.
@@CesarinPillinGaming “but can withstand temperature up to 1000 DEGREES.” 😈
I really wish you would have recorded all of the max overclocks and voltages on that CPU before doing these tests. Then you could make a part 2 showing how much you degraded it while trying to kill it. CPU degradation gets talks about alot online, but nobody ever has real data.
ive literally never heard a single discussion on degredation
@@siccoblue2112 Derbauer made a video on running 3 ryzen 5000's at 1.45V for half a year and then looking at how much extra voltage was required for 4.7 GHz stable.
I had a higer volted i5 back in the day, iirc 2500k. That thing went a good 5 to 6 years until it just stopped overclocking. Would still run fine stock. Replaced it with a 3770k untill i upgraded to 9900k, and now im on a 12900k.
Edit wow what jay did in this vid is basicly what happened to my 2500k, it was only about 1.3 to 1.35v, but that was a lot back then.
I used to have my 8700k oc'd to 5ghz until it became unstable unless I shoved voltage down its throat so now I just do 4.7. But yeah some tests like that would be cool.
i have an old a8-9600 that has degraded horribly from being at 100% trying to play roblox all the time, but now the pins are extremely bent :( i was going to use it for a secondary streaming machine since i upgraded last year.
Nick's pause before laughing at the back to the future joke was great!
I love the irony. You can hook up the CPU to a car battery and stress test it inside a microwave and your computer will protect itself, there is no damage. But you bend 1 pin in the motherboard and you are done
So I've recently installed my first aio and apparently plugged it in to the wrong port, which I didn't know. My system turned off all the time, running an 10700k.Upon inspection I noticed it was getting up to 115°C in the bios... It still works for some reason. Cpu's are tough 😅
Yeah 10th gen handled heat ez, go over 100 on 11th or 12th gen and its wraps
I dont think it likes that temp but a few tines its prob fine. It will damage over time id expect
Yeah, it may degrade over time at those temps but in practice the chip should just thermal throttle anyway. TJmax is 100 degrees after all.
@@nebula2294 oops, my 12900k reached 100°C plenty of times and it still works without any problem.
0:52 "it's not fair, we need CPU's"
well.. someone needs to blow it up to see what happens, and it ain't gonna be any of us :P
So this is Jay's version of a Cletus video. SWEET!
I wonder what would happen with something like a Ryzen 5 3600, I have that chip and the idea of accidentally adding too much voltage (killing it) scares me. It's good to see that your chip stood up to the abuse
I almost accidentally did that to a Ryzen 3 1200 a few years ago. Scared the living hell out of me when I saw it idling at 60*C.
I see you have been visited by the JayZ giveaway bot.
A power surge managed to cook the PCIE lanes of my 3600X once before, had to RMA, whenever GPU drivers installed Windows would corrupt and need to be reinstalled. I assume this happened because I was 4k gaming CP2077 at the time and thus the PCIE bus portion of the CPU was doing a shit ton of work transporting all that data. It was such a nightmare to troubleshoot without a literal second set of parts to swap out to process of elimination troubleshoot. CPUs are hella resilient relative to some of the other PC component types, however when they do break boy is it a pain in the ass to deal with.
I had a Ryzen 5 3600 and I think that happened me but I think it was a power surge from the PSU that killed it although it not 100% dead just dead enough windows won't install. Got a 5600x now so academic but had to use my FX8350 until I could afford a new Chip and MB. That PSU was a CIT500W no longer being used new System is using a CX650F RGB, didn't want the RGB just want the white cables worked out cheaper than buying a black CX650 and cable extensions.
@@ShadySKWASHA Lol think we had the same issue them I assumed it was the PSU that cause it if I had another Zen chip I could have diagnosed the issue right away but I didn't and at least I had my old FX to fall back on.
I love that evga board bios screen so many things to change its realy impressive. And that cpu deserves a service medal.
The locked clock speed is exactly what happened to my 7700k when i overheated it. it locked itself to 4.37GHz. so this is really interesting to see it being replicated
Interesting . Same thing happened to me with my 4790k . I thought i was losing my mind but i kept checking at ya, locked and wont act "normal" now . Im just glad it still functions lol
similar thing happened to me with my old 2500k on p67 sabertooth board, seems the board took some damage from dying PSU (cx750m), cant set multiplier and second PCIe slot is dead, but it turns out the cpu is still fine pushing 4,5GHz on air with low end Z77 board 6 years later, max on sabertooth was 5,3GHz with water
@@dubi127 so at the end its a fail of the motherboard and not the cpu? When it only loads 3,6 ghz but on other mainboards its fine with 4,7?
When he changed the board, the cpu was fine... maybe the board is damage and not the cpu? 🤔
Same thing happened to me on an AMD a7 APU
I was quite alarmed when after a bios update and leaving precision boost overdrive turned on for my Asus Crosshair VIII Extreme, it was throwing 1.61 volts to my 5950x.... That's the fastest I've gone back to bios. Temps were fine due to custom loop. But the fact it was feeding over 1.6 while gaming and just letting it sit there without changing any bios voltage or overclock settings was terrifying.
First thing I do on any motherboard is to turn off load line calibration (set it to minimum/highest VDroop) since at auto voltage it's redundant.
@@ascissordollynamedgwen9409 my a6 6400k was eating 1.4 volts at stock lmao
@@ascissordollynamedgwen9409 it threw me off when i went from intel to ryzen with my 3700x, it booted for the first time at 1.44v while showing like 3600MHz. But it stills runs today at 1.38v at 4400MHz waiting for my 5900x to show up
@@ascissordollynamedgwen9409 just got my 5950x but it only boost to 4ghz all core? is this normal at stock settings? also voltage is 1.1V, im using a B450 motherboard and the cooler that came with my R7 2700 non x, temps are ok for the stock cooler, 74C when gaming in CPU intensive titles and mid 80s in cinebench R23, got a score of almost 27k .
@@ascissordollynamedgwen9409 I thought the 5ghz was all core xD well guess it is right, maybe the vrms is what is causing my CPU to not boost a little higer, also how can you see 5ghz? I use hw monitor and ryzen master and none shows the CPU actually going above 4ghz .
This was a lot of fun to watch. Next time though maybe do a "no regard for safety, one drag race run" overclocking?
These kinds of videos are some of the most fun to watch. Keep 'em coming Jay
You watch Cleet? Hell yeah, i knew you were my real dad 🤣
Good point though I read in the comments: what would we have to expect on Ryzen with such an experiment?
yeah would like to see that as well
preferably 5900x or 5950x with so many cores as they have
i shoved by mistake 1.6v on my 2600 non x still fine.
AMD boards happily shove 1.5v at the CPU's by default (much to my horror the 1st time seeing it). It'd probably make it to 3v.
@@Accessless so yes and no... Yes they can shove high voltages on Ryzen but... There is a thing called clock gating so the effective voltage is significantly lower. It's not straightforward like Intel has.
@@Accessless and no. The max vid is 1.55v. As long as you don't set a manual voltage in bios, all Ryzen chips out currently can only do 1.55v. It takes a couple of hours on the SOC to kill it.
I have run my 8086k at 5.4 all core 1.47v constantly for many years now. No problems at all and I am due an upgrade soon, so it’s lasted it’s useful life for me.
This smells like more XOC content from Jay.... oh, would that be a thrill! I know it's most "relevant", when there's a new GPU or something - but I still really liked that type of content from Jay and GN :P
I would love to see this repeated with like a 1st Gen Rysen 1800X or something, just to see if the AMD cpu's are as, uhhhhh ?robust,? as the Intel ones in the same test methodology.
What would you expect?
Well, I can't tell you about the 1800X, but I can tell you about the 3800X and it's one tough son of a bitch. For a while I was running mine with a manual overclock to 4.425GHz at about 1.425V. At some point I installed Ryzen Master to mess with it and I thought that it would override the BIOS settings, so I threw a +125mV offset on the thing (thinking that it would go from the 1.3V it started with to 1.425V). But Ryzen Master decided to throw that on top of the 1.425V I had set in BIOS without me realizing. I didn't pay much attention, so I started gaming. After 2-3 hours of playing, I removed my headphones and realized that the AIO fans were going full tilt, so I checked the temps. The thing was pinned at 100-105C, but didn't really throttle itself much. I panicked, reset everything and it kept working normally for the next 9 months, after which I sold it to a friend who's been using it for about 7-8 months now without problems.
@@959tolis626 , interesting, things sure have come a long way from 2003 when i got into building PCs i tell ya ! I am kinda trying to figure out what might be safe for my 1800X. I can push 4.0 without even touching the voltage, but am not sure what is safe for the long term, 5-7+ yrs. I also heard 4.2 was kind of the ceiling on 1st gen Ryzen, i assume due to voltage overload rather than temp, but idk.
@@shreyasdharashivkar8027 , i really dont know. It all seems to come down to the onboard throttling code regarding temp via clocks. I don't think he actually managed to fry it even after going ham on voltage, but idk if AMD has similar functionality, or maybe lets you disable more of the gaurdrails and actually manage to kill one with volts, idk.
I killed my 2700 with 1.55v on the SOC and the core and it took a few hours for it to die.
Cleetus and Jay is the crossover I have been waiting for
DId not think Cleetus would have influenced this, considering the destruction Whistlin and Demoliton Matt does!
This definitely became one of my favorite vids from you, I’d love to see you do more torture testing vids like this.
10:35 That voltmeter reports that the cpu hit 1.887V, then right after 1.537V and next 0.763V. I think that those values are the max absolute voltage, max turbo clock stock voltage and base clock voltage. The board just does a test on boot to test if the cpu is properly working. Like a max, medium(turbo) and minimum values of the cpu table of voltages in that motherboard.
You should try the 1.887V (reported on voltmeter) with 3GHz all-cores and do a 3dmark or Cinebench test just to check if it passes.
17:07 Lmao, Jay cracks me up!
Hands down my favorite Tech channel; with character!
I appreciate this video, it's very interesting to observe, and to help educate people who are deathly afraid of voltage. I think you should've gone more into depth on idle vs load voltage, how Vdroop works, and perhaps explained transients because those definitely were a factor in this.
My 4790k died on me a few years ago. Well it didn't die, exactly, but I think it needed more initial voltage to POST than it was getting from the mobo.
Sometimes after multiple bootloops it would eventually POST, and then it would run fine for days, until I powered off the PC.
I could game, run stress tests, and do everything, no problem, but once I switched it off there was no telling how many bootloops it would take to get it up and running again.
I was so convinced that "CPUs don't die" that I bought a used mobo on eBay and it behaved the same; it was a $20 "broken" Z97 Deluxe (that wasn't actually broken) and it came with all the extras like a thunderbolt card, wireless charger, NFC, Wifi, etc. So I was delighted!
Ended up RMAing the CPU with about a week left on the 3 year warranty.
If you're not smelling burning cabbage you're not over volting it.
Actually would quite like to see Jay to an old school oc video. Talking pumps from an aquarium, modding an air cooler into a waterblock, car heat core radiator and the classic of pin modding a cpu and accidently frying it.
You've gotta do AMD version of this!! Thanks for the awesome content!!
I've dealt with PC where the PSUs have exploded Gigabyte-style, and others that caught fire and the CPU usually survives. Usually the cpu death come slow by electron-migration and degradation.
Interesting!
i have never found a degraded cpu (i dont usually deal with overclockers, so i guess that is why) do they have symptoms? or just plain die one day?
This is when having an oscilloscope would be really useful. You could see the exact voltage spike when powering the the system on, and how long that voltage is there for. A standard DMM isn't fast enough to really give you an idea.
Literally was just wondering this… as always you read my mind Jay. Keep it up man, your videos keep me sane at work lol
"Look at this guy, who's trying to kill the hell out of a CPU!"
How to make a Holy CPU by JayzTwoCents
@JayzTwoCents - this was interesting! I was kinda expecting the CPU to be bricked eventually. I'm curious though - what if you tried to do the same thing with a Ryzen CPU?
The most voltage I've personally seen on Vcore was when a friend of mine had me overclock his i5-3570K on an Asus P8Z77-V LX2 running an older BIOS.
There was an issue with that BIOS ignoring things you set, so for one boot, it decided that our overclock was fine, but it wants to see it with Vcore on Auto. Since the clock was high, the board decided to pump 1.597V into the CPU. For context, it was cooled by a basic slim tower cooler, and we set the Vcore at around 1.325V. So nearly 1.6V was definitely not what we wanted to see.

I love the cleetus inspiration...makes me feel good we could have been watching the same videos around the same time more relatable. Love ya bud
I once ran an Athlon x4 845 for like a week at over 1.6V in order to run the BCLK high enough to run the chip at 4.54ghz, it was surprisingly stable, and I backed off from there because of the junk amounts of L2 kept it from being a not slow chip
I ran some old 1st and second intel i7s on 1.5-1.6v also ran a Pentium 4 at 1.65v to hit 4ghz with it.
Taking inspiration from Cletus McFarland.. seems legit
I think the whole pupose of this experiment was to produce a new comedy routine and you nailed it 😂😂
Cars and tech in one video never been a better video
So there are 3 factors which can degrade our cpu voltage; current and temperature. You will not experience degradation by keeping your cpu under 85c.
I know for fact, 10th gen will experience no damage up to 1.52v (apparently you will see some damage at 1.75v in one week and not at 1.7v in the short term, 3-6 months, no data to confirm).
The tricky part with high voltage is the current, so u can go at 1.52v and stay super safe if u have a 28A limit on each core.
If you break one of those rules, that will kill your cpu in the long term.
Id love to get someone from like intels engineering department to come on a video and discuss whats probably happening
Man wouldn't it be hilarious to see Jay get in on one of Cleetus' crown Vic races? What a crossover that would be. 😆
🖕 Congratulations you among the selected winners claim your PC via telegram 📩⬆️⬆️
adventures in screwin around with computers is what I've always loved about your channel.
I'd like a deep dive on memory overclocking. Specifically Ryzen DRAM calculator and how to identify different settings in different BIOS. Each mobo vendor decides to change the names of these things. Also certain settings seem to be missing, I don't know what to think about that. I'm always afraid I'm increasing the wrong voltage too much because I misunderstood the name of the setting. One voltage is a flat number while another is a stupid offset. I'm never sure which is which and it never bothers to say what the setting is currently at. Also this should cover boards that aren't super peak expensive, but the stuff that actually sells well and people are using. My $130 B550M AORUS PRO that supports DDR4 4733 for example.
Buildzoid on his channel actually hardcore overclocking goes in memory oc deep drives.
@@BringTheSteak yes, watch Buildzoid.. Truly the master...
Haha it's great to know you are a fan of cleeter
wow I never thought a CPU would survive at the voltages you're dumping into that thing. That's impressive. Says a lot about how tough modern CPU's are.
Hearing you mention Cleetus and the Freedom Factory makes me smile. I'd love to see you go there one day, maybe for a Jay/Nick Le Mullets!
This whole video was great.
Supposedly if you were to go above 1.4 on first gen Ryzen, there would be permanent damage, so maybe try to kill that too.😂
I've done 1.48v on both 2700 and 5800x without killing them. Would love to see someone do it on first gen Ryzen.
well... mine didn't die or seem to suffer. I had a R7 1700 that I tried to bench at 4.1 ghz with 1.48 vcore... it failed, but the chip was fine... I could run it at 4.0 ghz with 1.45 vcore with no issues. Perhaps the custom loop cooling I had left over from my FX overclocking days made a difference, but I doubt it... edited to correct typo
@@minotaurbison Sounds like we need to give our CPUs over 1.48v......My poor 5800x is going to regret this.
The most i put through my 1600x when i had it was 1.39v i think, take the frequency up to 3.9 GHz, was scared of touching 1.4v
@@tyf.4399 You guys must have dog shit chips
Fire in the disco! Fire in the… Taco Bell….
I went to the store to get more fire!
Apparently that sort of failure can also naturally be caused by a bad voltage regulator if the voltage regulator goes bad.
Considering this from the engineer's pov, I have a feeling that the broken turbo is more of a "some idiot is at the wheel please don't listen to him" mode... or it just broke which honestly would also be fair at this point.
Love the Vids Jay, Nick, and Phil, keep busting out of the box with these ideas!
I was thinking maybe it has a turbo “fuse” or thermistor, something like that which got that hot too hot and needed to cool off for a bit
A fellow Cleetus McFarland viewer, I love that you took inspiration from that video in particular, because just like that car wouldn't have been useful to anyone in the condition it was in.... This CPU gave its life ... For science!
ditto. I didn't think I'd hear Cleet's name on this channel ever.
11:50 Would the "punching effect" apply to every other device? Hopefully not as confirmation bias but Ive had a few hard drives circuit boards die from turning the pc on. Different wall outlet, different hdd brands, different mobo, different psus etc etc.
Because of this would it be unreasonable to always leave the pc in sleep mode or in low power mode, rather than turning on from scratch, or is it unnessecary paranoia especially with newer parts. :)
t can, but generally HDDs aren't effected by system voltage. Some PSUs have had some pretty shoddy regulation on the 12 and 5v rails, so it's possible that in turning a PC on with one of those that you might end up with more than the required voltage for a bit. Over time, that'll lead to failures.
@@nightbirdds My psus are always silver and up from reputable brands, not some random gray ones. Perhaps my hdds were on the older side but they were quality when I bought them. I have no evidence or timeline to substantiate my claim but I can say it did happen a few times in my lifetime
I've turned off every single pc build I've ever had every night and turned them back on in the morning. 25 years of use, 8 different PC builds, never had a drive or other hardware failure at boot, but definitely had 4 failures after a few hours of use... 2 of the failures were hard drives dying of old age, one was my old Geforce 6800gt dying from cat hair, and the other was a no name brand POS motherboard in 2003 failing due to chinese capacitors. Unlikely you could ever trace any of that to power cycling.
@@scythelord To reply to you and everyone that sees this, I was probably just really unlucky, especially being reminded of the voltage overshoot which comes back to me as a "wait duh" moment, but its possible ive just gotten some of those good ol 1% batches, or the voltage went to 5 volts or something, idk
Initial start is always hard on every machine. Engines in cars take the hardest hit when you first turn it on, same as HDDs, AC units, and CPUs. Manufacturers take this into account when designing them, so it's nothing to worry about
I love experimenting with stuff so naturally this is now my new favorite video.
Well Jay, as the Mythbusters often said: "It's it worth doing, it's worth overdoing." You go right ahead. These are some of your best videos, including the one where you put different fluids in a watercooling loop.
Intel: hard to kill cpu
AMD: bend the pins. CPU dead
Would have been interesting to see the effect this had on the CPU. If there is any difference in Cinebench score, if there is any significant decrease.
all that matters really is the frequency it's running at, which you could see got lower for some reason, so yeah. The score did decrease.
This is what happened to my 2600k system. Last year my system started crashing once in two months, but the crashing became frequent from monthly to weekly and then on daily basis. Before its ending days system used to stuck on boot loop for couple of minutes everytime I start it from cold boot. In the end the turbo frequencies got locked to default boost and it didn't let me change anything from bios like yours was happening. So I had to get a new system. Damn that was a good CPU.
I feel like more than half this test was the CPU, “aiiight, imma head out” over you guys’ humor lol, great video to end my day with 😂
Jay: I wanna provide as much cooling as possible
Me looking at my floor fan with a 2 foot diameter thinking: that not enough cooling
Hey Jay! How much voltage draw is there when waking from sleep as compared to cold boot?
Coming back from sleep should basically be the same draw as when he reset the machine. Only on the first cold boot did it spike, and I would expect the same behavior from a sleep state as the power is not really off in sleep, even though fans, etc are not running.
@@420inportland Thanks for the reply.
The spike is normal and as expected since it's before Vdroop
Really great vid, agree with all the comments here. Really learned a lot thx! Only suggestion is for stuff like this have multiple cameras going, one fixed on the screen, one on the motherboard, the panning back n forth got me a little dizzy.
The thing about running CPUs at high voltages is that it greatly increases electromigration, which can eventually cause CPUs to fail months or years down the road. This effect increases substantially above 1.4 volts or so (and is exacerbated by high temperatures, which ordinarily aren't terribly dangerous but combined with these voltages, can greatly increase wear).
The reason that CPUs can easily handle being pinned at 90-100C during heavy loads without failing is largely because the voltages are usually low enough to avoid electromigration becoming excessive (at the normal voltages CPUs run at, this isn't a huge issue). When you throw voltage through the roof, the higher temperatures (combined with the higher voltage) make this a much bigger risk, which puts more wear and tear on the CPU over time.
Still a very fun experiment, and I'm impressed that it even runs at all with these kinds of voltages!
Jay wants to kill a CPU: I WILL NOT DIE!
Jay doing an average OC video - CPU: Sorry Dave I cannot do that. I'm dead now
Your problem with "trying to break a CPU" is that you didn't have Linus Sebastian handle it.
Man i love jay for talking about cleetus im so happy its nice to have another car guy thats also a tech head
The Cleetus McFarland video reference made me remember you're a car guy also! Just watched your R8 Rear Spoiler upgrade and loved the Carbon Wing! Love everything you guys do!
This is good to know because im terrified to mess with clocks and voltages on my cpu's
Can we take a moment to appreciate the absolute marvel of engineering that a CPU nowadays is?
Jay you'd want to use an oscilloscope to read rapid voltage fluctuations at startup. There's a number of reasons for that transient reading of 1.5 - 1.7v to show up at button press but I wouldn't trust a multimeter with it.
I love that two of my favorite youtubers have the same interests.
The biggest thing with having a high VCore that seems to happen is you need more voltage to get an OC stable that used to work just fine on manual before your auto-ridiculously-high Adaptive was applied lol
This video was amazing, I love the longer style videos and more loose unplanned stuff, nice change of pace
I love these kind of videos where we get to test things like this!
The x99 was one of the beefiest things you could buy during the time. Broadwell and haswell Enthustiast builds were top of the line and an overclockers dream if I remember right.
Yeah, I have an x99 PRO Asus mobo with a 6950x Extreme Edition and the thing still rips. Seeing as how it is still really hard to fully saturate a PCIE 3.0 bus, and having SATA SSD's zippered together in RAID 0...a damn near 8 year old system can still clean house.
@@worstcat8489 tell me about. I have a z170 MSI titanium X-power motherboard with a 6700k skylake build with a win 7/10 dual boot.Thing still runs smooth to this day
Good effort Jay, you did your best but some things are just impossible!
Seeing that Jay also watches Cletus, let’s me know he’s also a man of car culture 😁
The exposed die stuff from AMD way back when is what cooked itself alive if a heat sink was removed, or the thermal paste wasn't doing its job. IHS's dramatically improved thermal efficiency, and with voltage and heat protections, your cpu is pretty safe. It still can't handle a severe voltage spike though, like electrical surges or lightning strikes.
Awesome vid, I am now curious about testing other "safety features limits"
Loved the shoutout to The Freedom Factory! Know ur a car geek too so cool to see you’re a fan!
I loved learning that my favorite PC/Tech youtuber watches my favorite racing/car youtuber. Awesome!
My favorite type of video. Jay does it so we don't have to!
My 5800x is getting really hot at 90 C so it’s great to see this kind of video lol. Keep it up!
That's not a good temp , Intel CPUs tend to run hotter and can handle higher temps than ryzen. You should definitely do something about that
People always called me crazy for leaving my pc running all day. I always felt like it was hardest on the components at startup from just how all the fans ramp up. Glad you confirmed my suspicions.
This guy is destroying the same CPU I have in my system right now, and I'm crying. It's a perfectly ok CPU that still preforms great.
The reason the motherboard shows fluctuations and the DMM is not is due to polling rate. DMMs dont update very fast because the normal application of testing is house wiring, automotive etc. The DMM just takes an average and displays that. Where the motherboard is probably more real time updating.
The hitting the component with voltage is called inrush current. The inrush is the demand needed to start the component to doing what it needs to do. Inrush happens on electric motors, micro proces, led lights, and everything else electrical.
When this man dropped a Cletus line I knew Jay was the real deal been watching since the original Subzero build!
Jay: "Science!"
Cave Johnson: "Science!"
Hey, I'm actually not too far from Cleetus's place and my buddy's grandpa was the original designer of the track. Which reminds me that I haven't been to the drag strip in years. (Bradenton Motorsports Park which I don't believe is owned by Cleetus)
Nope its owned by Victor, one of Cleets close buds
Maybe the best most informational video I’ve seen in a while
Hell yeah brother, 2 of my favorite channels!
I love that you watch Cleetus. Got me saying FULL PULL when you stress test. DO IT FOR DALE.
this was alot of fun to watch and it shows how much fun you guys are having.
Phil, you missed a great moment to insert a Serj Tankien image over Jay's head when he yells "WAKE UP!"
