CPU Degradation

[searaider]

Because i'm doing an overclock and because i've read in some places that overclock can make cpu degradation with time, i would like to know from you what can cause that? high vcore? high pll? what?

I high voltage and temps cause the majority of failures. Even if you can control the temps high voltage takes its toll.

My old Q6600 would not last long at the 1.56v needed to keep it stable @ 4.2ghz. But 1.425v for 3.6 ghz should not be a problem.

Voltage is the only major factor in CPU degradation. Heat, unless excessively high, will not harm a CPU, since they are designed to withstand significant temperatures. With a 45nm CPU like your E8400, you should keep the CPU voltage at or below 1.4V at all times. With a 65nm CPU, such as a Q6600, the voltage should be kept at or below 1.5V.

I had a q6600 @ 1.65 on water for the longest...

Still, it's a risk but the price of cpu's nowadays makes it easier to digest if you bust one.

Greetings, but how about pll? if it is too high can contribute also to degradation?

Yes. All CPUs are susceptible. The actual amount of voltage that will lead to damage depends on the specific type of CPU however.

I´ve tried to reach 4ghz with mine but wasn't stable maybe bacause i'm affraid of going beyond 1.36 vcore, so now it's at 3.8ghz with 1.31 vcore

3353ish depending on exact clock...i'm running 419x8 on a Q6600 at 1.37v under load...

it's all she'll do...anymore and it needs an assload more voltage for ever diminishing returns...

temps are reasonable though...20's idle and low 40's under prolonged 100% load (cept burntest...low 50's)...can't beat that...
