Who has damaged/broken a CPU from overclocking?

I have no idea if i could even kill a processor. The only time i've really tried to overclock using voltage, i've been stopped dead by a shocking motherboard. Asus M3A78 Pro (DO NOT BUY THIS BOARD). No matter which BIOS revision you use, it doesn't let you take vCore above 1.3v, even though it sticks at about 1.4 if you have it set on Auto....

I'm never buying an Asus again, for my own systems :) budget stuff for other people is fine, but never for myself.

I've never killed something by overclocking too much. GeIL memory takes extra voltage like a beast. 1.8v stock, had it on 2.2 and it was running like a dream (if a little toasty). Got speeds from 800 up to 900 :) even tested it once on 1GHz and it was fine. Had to worsen the timings for the 1GHz test though... on 900 it was still on 4-4-4-12. Excellent.
 
2 volts through a TB1200 AXIA @ 1533mhz, 156watt TEC cooling normally ranging from 10c to 30c.

i got up to watch the Japanese F1 race (4am), it was -1c, with thick fog. My water cooling radiator was outside, so i turned the PC, put the radiator fans on min speed while watching the racing. The low air temps + thick fog meant my water temps dropped massively (from hot enough to bath in, to cold) and my cpu temp was -17c at idle, so i stuck some seti on to boost the temp, to 10c... However while it was at -10c, ice had formed on the cpu and now melted. My insulation had not done a good job, however it did hold the water in the socket area only, not allowing any to leak further down the motherboard or onto graphics card. I only knew i had a problem a few hours later when it wouldn't be stable anymore. My Last TEC cooling days. CPU became locked to some wierd multiplier and was rubbish from that point on.

Killed outright? hmm a PII350, trying to get the case off the Slot1 cpu, put a screwdriver through the cache chip....doh.
 
None, my current 45nm Intel chip is at 1.64v under a average watercooling system and It's not shown any type degrading at all.

I've set it that high as an experiment to see what Vcore these 45nm chips can take on a daily basis and so far it has taken everything I have thrown at it :D
 
I have killed only a couple of CPU's, but I guess when you in the world of extreme this has got to be expected, but saying that only two CPU's killed out of ( can't remember how many I have tested over the years) can't be a bad thing.

Cooling is the main thing, when a CPU start to draw Current when loaded things start to get hot and break down/degrade, making sure you have good cooling is the main thing when overclocking.
 
I have killed my Q8200 while doing something from 2.33 to 2.8 and accidentally selected 2.3 V.Restarted the pc...everthing was fine only that my CPU idle temps got up from 30c to 51c in 1 min.So back to bios to check the voltages and I saw 2.3 selected but when I tried to set it to 1.2-1.3 I was already too late.The Pc powerd off and the CPU was lying lifeless in the socket that became his coffin.:p Pulled it out and there were 10 pins burnt.

Edit:The thread name sould be changed in "Who has damaged/broken a CPU from overvolting" because most people said that they're CPUs died after overvoltage.

I've never killed a cpu through overclocking it, but my tweaking and fiddling has caused the death of one.

I killed a Duron 750MHz once reseating the heatsink, I rocked the hsf unit a bit too much when securing it to the socket and cracked the fragile exposed core on it, replaced it with a Duron 800 and a shim (remember those :p).
 
I've chipped a few cores back in the day, never outright killed a CPU though. Graphics cards though, I only really ever upgrade once I've burned my current card out completely or the card I'm hoofing gets 2 generations old.
 
I killed an Athlon AYHJA 'Y' 1.4ghz chip through too much voltage. The overclock just gradually became more and more unstable, until eventually it wouldn't even be stable at stock. Trying for 1.7ghz on air was not the best idea I'd ever had.
 
Never killed a CPU but I did murder my old gfx card many moons ago....only after the new one arrived though :D
 
It's all about the cooling. Which can degrade over time as fans get dusty or even fail. As long as you get the heat away, they generally will keep working fine.

I've burnt out a gfx card and a processor from overvolting and not cooling enough.

Electromigration can kill even a well cooled chip, although it can take time. Ask anyone who fed too much voltage into a Northwood P4...

yup, all my CPU's have gradually lost speed to the point they no longer run at stock. I put it down to Electromigration. Dunno if that is the case though.
 
my e8500 was knackered but other than that the only thing have broken was somehow both the gpu and motherboard on and old 1900+ system because of the fan cutoff switch on a mesh computer when the door came off :confused:
 
Back in the days I think I killed my Intel Celeron 700 because of trying with to much voltage. It just wouldn't boot in my and my mates pc.

I've had no trouble with any of the other chips I owned. Though right before I sold my E2160 it wouldn't overclock as far as it did before... put like 1.5 - 1.6v through it to get it stable.... maybe it was a good choice selling it after all ;)

The fun thing about cpu's like the E1xxx, E2xxx and now the E5xxx series is that you don't feel bad when putting a lot of voltage or whatever through them as they are so cheap and easily replacable :)

i've never burnt a cpu, i've even overclocked to extreme levels when ever it becomes unstable it just restarts pc, plays around a little with ya, but when you unplug the power cable and put it back in, all starts normal @ default.

however a friend of mine did cook his agp graphics card, he took off the fan + heatsink that came with the card, and put his own custom one in, the thing is, he had a cooling system built in to his tower and it was powered by a seperate power supply unit which he would only switch on while gaming etc.

and you guessed it, he played a couple of hours, didn't switch it on and started seeing artifacts on screen, paid no attention cause he was so into the game and a few moments later, pc turned off and didn't turn back on until he changed graphic card.

he still has the card, i'll get him to send me a pic for u lot if you like.
 
not yet, and im running a canny lot of volts through my quad, they are built to last for a long time, i tend to update them before the expected life span anyway
