If I'm not mistaken, then I think $ilent has some experience to back this statement up.

 

$ilent, was it you who had degradation of a 2500K after like 7 or 8 months of constant 24/7 load at 4.8 GHz using about 1.4V?

It was I made a thread here - http://www.overclock.net/t/1309067/sandy-bridge-degrade-at-1-4v-you-bet/0_100

However I think it was more a case of 'break in' period, like a pair of shoes. I had been folding on that cpu hard for 6 months too. Ultimately I dont think the cpu had degraded.

I think he had to bump up the voltage by 0.04V or something after 8 months of 24/7 load. It's not really a big deal, since you probably won't be anywhere close to 8 months of 24/7 use on your chip. 1.45V is pushing it a bit, but I wouldn't be afraid to have it at 1.4V or a little higher.

Yeah, so the point is that I'm being extra careful by recommending no more than roughly 1.35V, perhaps unnecessarily so.

Yeah, and the fact that he's trying to make it last 3-5 years "at least" makes me feel that being too safe can be the best choice (not "is", but just "can be"). I'm not sure though.

So thanks for the advice and from what I understood is that being under 1.35 vcore and max temps at around 70 degrees Celsius will keep my cpu running for another 3-5 years am I right?

You should be OK yes.

I've been using 1.45v for 5ghz on my 2500k, this is recorded during IBT

During lower loads, the voltage will be around 1.5v, for example during starcraft 2


Heat wise, 1.45v for something like folding during the summer won't cut it as I only have a thermaltake frio, it will hit 95C on IBT

However, if I'm just playing starcraft or crysis it's a brisk 55C tops if even... thumb.gif


As far as degredation... So far nothing on my 2500k w/ asus z68 pro... On my other 2500k w/ extreme 4 mobo, same cooler, I've had to increase my voltage ever so slightly to do 5ghz.. So... IDK, maybe

It could be that the extreme 4 degraded, or the 2500k degraded... but it's a very slight 0.05v voltage bump AFTER a year and a half


Either way.. I don't give a ****.. because I got the first chip for $200, and second chip for $150, and bought intel insurance on both because I wanted that 5ghz..

And to be honest... I am sure as hell not riding this thing for 5 years... because that's about how long it takes for 50% increase in IPC.. I would upgrade around the 25% increase which would be 3 years biggrin.gif

And in 3 years, I'll just downclock by 200mhz and give it away as a prize at something... thumb.gif

^Extreme 4 motherboards under report cpu voltage so 1.40v is probably closer to 1.45v.
