How much voltage does it take to hurt a CPU?

all right i have never done a video like this this should be quite interesting we are going to blow a cpu up because i'm curious as as to what point it happens designed to bring a balance of performance and cost to gamers the bg5 m.2 ssd from keoksia is an obvious choice the bg5 ssd utilizes kyoccia's fifth generation 112 layer by cs flash 3d memory and uses a dram list architecture leveraging host memory buffer technology to maintain affordable power and efficiency and for those needing a more robust storage and professional use geoxys cd7 features pcie gen 5 and 32 giga transfers per second perfect for enterprise and data center solutions to see the complete list of storage options from kyoto whether it be for everyday use and pc gaming or professional enterprise and data center solutions follow the sponsored link in the description below i can hear you guys already that's not fair we need a cpu and then you're blowing up a perfectly good one this is an intel confidential cpu i could not give it away sell it trade it or have it leave my possession so that sucks for you guys because i can't give it away but anyway it's a 9900k i didn't want to blow up anything really new or like super useful but we have other 9900ks and i wanted to use this specific config for a very specific reason this is the z390 dark motherboard from evga it has a built-in cpu stress test right here so stress test right so this will automatically start stressing the cpu it's not quite as stressful as say like cinebench or something but it gives us voltage reading frequency as well as temperature now i'm not planning on necessarily doing any sort of overclocking because i'm curious specifically about the voltage i want to see what happens to the cpu if we over volt it and remove all of the safeguards this i was a little bit inspired by a couple of things one cletus mcfarland's recent video where he put gasoline in the oil like remove the oil and put gasoline in and actually was able to run 17 laps with the crown vic around the freedom factory before it completely like blew a hole in the bottom of the engine this is sort of like the same thing only this is if we just did a massive tune on an engine with no safeguards whatsoever now there are obviously built-in safeguards in the system where and i'm looking at what the temperatures are currently right now because this is our limiting factor right here we need to disable any sort of overtemp protection because if i were right now to pump the voltage to say what does it allow on this motherboard up to three volts right now we're in normal which is up to 1.4 volts extreme goes up to 3 volts warning high voltages can cause permanent cpu and or system damage it's the end or system that worries me that's why i have all these other fans on here because as i'm pumping a ton of voltage into the cpu it's going to put a huge amount of stress on the vrm so the vrms have to supply that voltage i also have uh some on the chipset down here although it shouldn't be affected i also have these three fans on full blowing across the motherboard i'm trying to provide as much cooling to the board as possible before the cpu itself goes to put i'm also running kingpin kpx on here what i could have done is just like the old days just not put a cooler on there at all turn off the safeguards turn it on and watch the hotspot form in the center and then have it eventually melt itself to death but we very well could potentially destroy this motherboard by doing this this should be seen as nothing more than just science for the sake of seeing what happens i know it seems wasteful but like i said i couldn't give you guys a cpu if i wanted to it sounded like i didn't want to i like giving you guys stuff i just can't give you this one okay you know no you know what i'm gonna start at like 135. override is where the voltage we dial in is the voltage it's going to do right so we have to reboot that and it should come on now around 135. that's pretty solid look at that 1.305 that's pretty close so now if i stress test this look at that we immediately jumped up 5c and look at the voltage though 1.334 under load that's because of the v drip settings i just i just did so if you want to see how v droop affects it so i want to give you guys some information so it's not just look at this idiot on youtube blowing up cpus for the hell of it no this these are the risks you take when you start overclocking and i want you to see specifically how v-droop and voltages obviously affect temps and such but yeah we're already at 65c by bumping up the voltage 0.1 or 100 millivolts so that dramatically affected our temperatures right there um also this obviously has a lot to do with the cooler that's on there as well so this is a 360 aio it's decent for cooling these temperatures are less about the liquid thermal capacity in this aio and about the transfer of the heat out of the die through the ihs into the cooler but if i were to go now to the droop and just put this back at default i'm curious yeah look at that see there is droop now and look at the difference in temps between 1.33 and 1.275 look at that 6c so by adding droop right more droop that means it's going to go down lower than our target so 25 less droop that should be right about where i want it to be yeah so there we go you see not really much of a change with temps about about one degree so it looks like minus 25 is perfect to keep it right on our target let's go 1.35 and i don't think that's going to apply unless i reboot right yeah oh what okay i didn't know that i could do this without a restart so that makes this even simpler because it means i can keep it going and booted i believe 105c is our limit so two volts is our max not three anyway i can't find anywhere in here where it allows us to turn off the thermal limit 1.35 i just want to see where our temps immediately shoot to okay so it's about 65 66 over time obviously it'll go up a little bit but i'm really curious as to where the initial slingshot goes to so i'm just going to go ahead and cancel that yes i know we're not saturating our fluid i don't care about the fluid i'm not testing the cooler is it funny how point or 25 millivolts is like 2c so we're about to hit 69. we have to hit nice and then 70. that's only 1.376 so what's funny is the new cpus are using this much voltage and you can see now why they get so hot that much voltage for the e core p core and then it's hitting like 90c on water i'm legit concerned about my uh 12th gen system i'm building for myself all right here we go 1.4 now is where we're going to start seeing things potentially get a little toasty but you know what though to be honest this is not the most demanding stress test it's truly not i just didn't want to install an os i'm going to do 25 millivolt increments 1.425 i really would like to know what what kind of test this is running because if i tried that with cinebench that'd be an instant lock i guarantee it let's go one five that was well you went one point four two five to one five yeah i know because i'm trying to speed this up a little bit all right 1.525 oh it's red now angry what's going to happen here is it's going to hit that temperature limit and if it if it hits that hit limit and doesn't go any higher then i have to find the setting somewhere in this menu system that will turn off those safeguards this is a v this is a kingpin board it should not have safeguards it should just come with a disclosure look at where it's idling now it's idling it's so hot 1.55 it's just like the cpu is like what are we doing remember when the temperature was underneath these 1.575 i have never gone this high no i take that back i've gone 1.6 volts on an x299 79 80 xc or whatever it was i've got 1.6 volts on that hit six gigahertz all core so yeah this is now in territory where i've not really gone before all right 1.6 here we go i'm not sure we're gonna make it to two oh look at that i'm expecting this to be somewhat non-dramatic hey nick once you get the fire extinguisher off the wall too just in case because we blow up cause we blow a cap or something it's just gonna right after you said it's not gonna be dramatic how hot well i just watched the slo-mo guys video about the caps exploding so i don't feel any warmth at all like these v these vrm's are so beefy and with the fan blowing down on it and the fans going across it i'm not worried about the board tank's getting warmish on the intake side for sure and then it's pretty cold on the on the output side i wonder why no no 1.65 okay i think i think we're being like no the i mean we should see the frequency drop right if we're actually thermal throttling okay so if i go 1.65 now and we see the same behavior then we'll know it's throttling wow yeah but look 100c it's not going it's not going any higher that's too that's too locked unless it's just not reporting over a hundred and it's like 100 100 plus come on we'll go 1.7 yeah that's i think it's just not reading anything higher than 100. 1.75 okay that to me sounds like protection because the cpu died right now yeah yeah they wouldn't even power on like pushing the power button nothing would happen yeah so that's protection that's like voltage condom right there i need to find where the settings are to turn all that crap off so we went ahead and hooked up the multimeter here and i gotta make sure these do not touch that is direct vcore probing so it says 1.238 volts so there's 1.23122 so it's funny the software shows a little fluctuation but if you look like at the hardware it is not moving at all right uh under load okay yeah so 1.238 1.243 so you can see how these small fluctuations here like when it shows up and down which of course now i call it out it's not doing it are not happening here on this on the hardware side one point two three nine two three eight it's very solid i'm it's interesting to see what the voltage does at boot right point nine so on a clear cmos now we should go back to like one two again oh that hit one six 1.5 you saw that right yeah so okay how many people have experienced the cpu dying on a startup you're like [Music] there's your reason why like i said this in the video before i said when a motherboard turns on it like punches the cpu for a second like wake up there's your proof of it it's like boot looping now i wonder if we just broke the motherboard so anyway you saw that right let's let's do that again i'm going to turn it off watch the screen when i hit power watch how much and this is hardware this is not this is sensing the voltage it's not like software which could read weird watch this when i turn it on 1.24 on that one which was normal hit it again it's gonna restart nothing happens right turn power supply off turn power supply on let's see when we wake it up boom 1.47 so it hits it with voltage it truly does 1.5 so there's your proof right there that when you turn on your system that is the hardest moment for the cpu i like snapped on the screen that's pretty yeah and then money fell out of the sky hey there's a hole there though that's where money could fall from no we put money up there i shot things up there with an air gun all right 1.625 now we're back 1.617 so it is applying the voltage so i absolutely now could leave this running oh look at that look at that it's starting we're starting to actually throttle now see this yeah but that's fine what if i do this what if i because i care about the voltage right or if i just drop this to like four gigs right easy i care about the voltage not the frequency it's running at look at how much attempt came down 10c 700 i i'm shocked honestly that it has not popped already with what we're doing to it 1.65 it is doing 1.64 this is not a real world test 1.7 oh we're already throttling there but look it's 1.692 jeez i feel like look at the frequency yeah we need to turn off that that temperature limit almost every other motherboard i've ever had allows me to disable that 1.75 i guess we gotta you make it to two at least but it's throttling now which it wasn't before yeah it's probably hard let's go to one eight dude it's throttling like 1700 megahertz technically 29 this is impressive though it's literally like i'm doing everything i can not to die right now you know what i mean sure the frequency reduction is absolutely making this less of a problem but this is still the voltage being applied to the die okay regardless of the frequency it's running at this is still absolutely the issue here yep dude this is impressive though the way it can actually keep this from dying right now 1.9 dude this is stupid 1.8 gigahertz that's exactly like my e6300 was right there 1.86 gigahertz all right let's just go to two 800 megahertz but it can't throttle anymore oh there it goes two gigs or two two volts so the question is did the motherboard just reset itself yes it did it intelligently realized you guys are stupid and it redid everything [Music] [Music] it's the perfect time to show some of the behavior differences between the boards because look it's at 5 gigs and at 1.323 volts on its own because the asus boards especially back in that era were automatically applying like enhancements and stuff out of the box which is a problem because some cpus couldn't actually run those enhanced settings so things were crashing out of the box because the motherboard's fault and people thought it was a bad cpu so i'm disabling all that right now ai overclock tuner we're saying that to manual um multi-core enhancement is disabled and cpu core ratio i am going to sync all cores and i'm going to make that limit like 45 1.4 five there we'll start in the yellow how's that just boot i'll have to call out the temps they're in the little q code right here on the side that you guys can't see we set the max to 115 so we are allowing more voltage more temperature i'll be honest with you like i would have if you told me hey jay you're going to be pumping a ton of voltage into a cpu up to 1.9 volts and it's not going to die with a standard aio with even just turning it on i would have been like y'all are crazy because we have to use a windows test here we're just going to do 3dmark's cpu test and we are 1.45 volts which is high but not astronomically high 63 68 66 okay by reducing the clock from the 5 gigahertz down to the 4.5 clearly temperature wise it can handle it just fine because it's showing 68 on the package this is getting long-winded because apparently i can't kill a cpu on purpose v core 1.643 let's see what the temps do when i load something so here's the core temps right here 90 degrees it's like bouncing around look at that 90 is like 98 on the on the package for a second what if i run something like heaven to just put a light load on the cpu 107 on the package for a second look at that when it was loading it shot up to 107.5 oh yeah that was obviously the core that loaded but look look it's like actually pretty reasonable it locked up it says 88 oh i went back and it went back to the future [Laughter] it can't load 3d mark it crashes every time i get a load 3d mark see it hits 100c right there 106 on core 2 108 there it goes i've never wanted a cpu to die so badly and it won't so we've reached a power up cycle now where it's continuously shutting down see gets the 9c then 0-0 we might have actually damaged the cpu now [Music] 9c is straight up v core your cpu isn't getting enough voltage that's what someone wrote bro i don't think i i think it's the opposite of that one this is consistent behavior this is what i was looking for cmos clear clear oh my god it initialized this thing will die i can't kill it bro i don't have what time it's just i've been doing this for hours we need to label this cpu nick as toasted stretched i don't know what to call it but we definitely yeah this is a reused stretch bolt for sure [Music] we cannot get it to go above 3600 now um it's like the turbo is completely dead in look i'm i'm sync all course right and it was at 50 but it's target up here you can see it's applied look right so if i go to 50 okay our target is 50 50 right there avx is 50 because it's zero and then 3600 is showing so if i reboot look it will not turbo anymore so what if i do this [Applause] obviously it's ignoring because we are not booting six gigahertz right now although that voltage it could be that's the thing now look it's completely ignoring we broke the turbo i didn't know you could do that that is new to me yeah 3.6 it is just ignored everything i've told to do look at the vid it's all the way down to 1.8 you mean 0.8 or 0.8 sorry i'm so used to the ones but we're still throwing 1.572 v core at it but it's not converting into vid with the core clock though oh yeah it's throttling 2.8 2.7 for 2.8 3.1 it's why is it throttling there yeah that is weird because the current temps are not high enough for it to throttle it's like i don't i don't know which chart we're following okay we broke it in an unexpected way for sanity's sake i need to now take this and i know this video has been long guys but this is interesting i want to take the cpu out of this board and put it back in the evga board and see if it's behaving the same if it will no longer follow any of the things we're telling it to do other than voltage because the motherboard solely controls that that tells us we broke the turbo settings in this we are now back on the evga board let's see what happens i was like that's taking a while longer to reset itself okay three six that's expected now if i do the test it should go up to four seven it's a lot harder to kill a cpu these days which was all i wanted to show and what i was hoping for was a little bit of magic smoke i was hoping for potentially well i got one more try now with 5'2 okay so it is absolutely oh 5'3 was like nope which is that hard limit we kept reaching with the cpu alright guys that's it for today's video remember the old videos where you could see like somebody had a took the cooler off like an old amd cpu and turn it on you just see it like a hot spot for him i was honestly hoping for something like that so the good news is i do believe the cpu to be [Applause] fine it's fine i swear everything's fine it's a lot harder to hurt your stuff than you ex than you would expect so does this video serve as that purpose and you all can not be mad at me anymore because the cpu is fine i think yeah it's fine so you don't have to be at me anymore alright guys thanks for watching [Music]
