Chip killer overclock?

post #1 of 22
Thread Starter 
My sandy was a tough cookie.
My ivy, not so much.


Long story short. New chip, 4.5ghz 1.35v stable, ran half a day 4.7 1.495v, wasn't happy, back down to 4.5, needed 1.36v for stable after that.

NOW:
4.7GHz 1.505v idles 1.500 1.488 under workload
Before my pc was 80%ram/80%cpu minimum 24/7, on 4.7GHz it's barely cracking 70/70 cpu/ram



Is this voltage a true chip killer? Will I see more degradation just from running these clocks, is it acceptable or is it truly a suicide run? My temps don't break 75C but I know it's getting a lot of voltage to the chip
All advice/knowledge shared will be appreciated, thanks!

Most chips won't degrade like that, I say that at 1.5v 24/7, it will take a few years for it to die, a bit quicker if you run the PC 100% 24/7/365

But Ivy needs a 'break in' period, about 3-4days

thanks Pedro, you ever kill any ivy's or ran 1.5v for long periods of time?

Im still on AMD, and I still run 1.53v 24/7 with no signs of degrading, but thats irrelevant.

1.5v will run OK for about 2-4yrs, I know its very rounded, but Im no expert at predicting, it may even be higher, but if you run it 24/7/365, it may only last a year due to constant abuse.

for safe 24/7 voltage, under 1.45/1.48 is the max I would go

any chance you could point me in the right direction of where and how you got those numbers?
I'm assuming there is a thread where some long term testing was involved or something? biggrin.gif

Well, its stuff you pickup across the months in OCN, no specific topic, just experts talking about them, and if multiple people say the same, chances are its about right thumb.gif

I would also like to say my estimate for 1.5v is a bit low.

3-5yrs for non abusive use smile.gif

I ran 1.35 V - 1.42 V and saw degradation in as little as a couple months. My 3570K gradually required more and more voltage. Anything above 1.3 V I'd say prepare to to up the voltage after a couple of months especially if you run it in fixed mode.

I know multiple people who run 1.45v+ and havnt touched their vCore in months/years, I say tehre is athe exception for some batches now and then though thumb.gif

Well, while i thank you for trying to help i dont go by "chances" because a few people say, at the end of the day if my ivy bridge burns out tomorrow, you won't be buying me a new one and it will be my fault for trusting without proof/fact/research

i thought there was a proven test or something where someone or some people ran multiple ivy's at high voltages to test degradation and lifespan

since every chip is different and my i7 already either "broke itself in" or degraded, i can't just take risks biggrin.gif

yeah but <10 people out of 100,000 or 1,000,000 isn't a good number to test my luck on. $300 isn't cheap biggrin.gif
also, batches don't classify the performance or anything else in these sandy/ivy's anymore. its truly silicon lottery.
multiple people have same batch and chips perform complete opposite

Same. I ran 30 days plus with 80/80% ram/cpu at 1.35 with not 1 error.

I ran 1.495 for a few hours and my 1.35 required 1.36 :/ after that I just gave up it wasn't worth the insane vcore increase for the 200mhz, while the 200mhz helps, it doesnt help enough to lose so much lifespan on the chip

Im sorry I cant be of any better help, as I dont know of anyone that did it on multiple Ivys smile.gif

But if you do find one, then please post me a link thumb.gif
