i5 3570K 24/7 4.4GHz OC

post #1 of 7
Thread Starter 
I looked for an i5 3570K club or something like that to post this there, but didn't see anything (let me know if I missed it), but I'm curious as to whether a 4.4GHz clock speed would be alright for a 24/7 overclock. If not, what would be the highest in your opinion before a significant reduction of CPU life would take effect?

Right now, I'm running 4.4GHz at 1.168V (CPU-Z voltage reading. Core Temp shows 1.206V). I'm seeing idle temps around 30*C and full load temps averaging around 64*C and maxing out at 68-69*C using prime95.

I'm air cooled and using an ASUS P8Z77-V LK mobo. Let me know if you think this is an alright 24/7 OC.

Frequency really doesn't degrade processor lifespan, it's voltage. And since your voltage is really low then there really should be no noticeable degradation on the processor. I've been running my 2500k at 1.328v for about 2 years but it's 32nm and yours is 22nm. But AFAIK Ivy Bridge is pretty similar in terms of the voltages it can handle compared to Sandy Bridge.

Ya, I was pretty surprised that I was stable with such low voltage. I must have got a lucky processor.

Is there a magical limit on voltage or at least a hear-say maximum voltage before cpu life may take a hit? I've always heard that 70*C is the maximum temp that you would want to be at, and while that correlates with voltage to an extent, I'm not sure if it's the temp or the actual voltage that is really the factor that degrades the life of the cpu.

I'm 4.4GHz @ 1.248v with max temps the same but I have dual 120mm fans on my EVO, your good and at a lower voltage.
it seems 4.4GHz is a sweet spot for being on air and not delidding.

so let's get gaming, what's next GPU upgrade.?

Ivy Bridge can overclock well into the 90'sC...
72C or something like that is the stock temps..

It's the combination of voltage & heat that degrade, if kept cool enough more voltage can be used without speeding up degradation, if it runs hot, decreasing voltage will help slow it down. Both high voltage & hot temps at the same time will take it's toll.

Looking at your voltage & temps, your cpu will have a long & happy life.

Sounds like I have a little bit of wiggle room then. Cool!...pun intended.

And yes, GPU upgrade probably will be in the future. I'm thinking I might just do another GTX 560 in SLI for about a year and then do an upgrade to a newer model GPU. They so expensive! lol But I digress from the topic.

Thanks for the advice and assurance guys!
