1.4V maybe, 1.30-1.35V vcore for daily OC's Warning: Spoiler! (Click to show)

we dont know much yet about degradation over longer time,
but better be safe then srry right smile.gif

Intel lists 1.52v as the max vid range. VID is not vcore. Loadline is there by spec so introducing loadline which most people do when using those voltages changes things. Under load that 1.52v VID is probably closer to 1.4v. You might want to check out this older anandtech article which explains what loadline can do. I think that it is still relevant.

I don't know where that graph came from that you posted or more importantly where those numbers came from. I know that it wasn't Intel. Looks to me like some one pulled that from their rear end tbh.

BTW, the latest Prime95 also uses AVX extensions (same as any current linpack stress tester with AVX) to stress test the CPU, but when using Prime95 it takes 10-20x times LONGER UNDER LOAD to actually prove stability/instability and I'd rather be inclined to say that it's the Prime95 stress testing causing more degradation (much longer under load) than IBT/LinX could ever do (much shorter runs) ...
some chips will degrade when overvolted even if temps are not a big issue (will degrade more if temps are at thermal limits) and some won't, and most of them will also degrade slowly over time, nothing wrong with it, that's how it is smile.gif

Hey get off your horse cowboy! tongue.gif

I never said degradation happened in the first place, what I meant is that perhaps he was never really stable to begin with. IBT is NOT a reliable stress test, only good for having a quick guesstimate of your theoretical max temps under load. He eventually had to jack up voltages upon finding instabilities IBT never detected.

But anyway, he has already stated that it's a different chip altogether so case closed.

LOL! no sweat buddy, not shooting anybody here wink.gif
was just saying, because I like using IBT, it's much quicker (than Prime) for stability testing and in fact with Ivy Bridge architecture and WHEA warnings in Windows Event Logs, those are my current favorite tools for setting a rock solid stability biggrin.gif
I consider rock solid when no WHEA shows up in logs when under load of IBT running at least 20 rounds in Maximum stress mode (using around 14GB out of 16GB RAM). it works this way pretty nicely for me biggrin.gif

BTW, Liquid Ultra 5g arrived here biggrin.gif
tomorrow will get to deliding my 3770K chip, wish me luck redface.gif
hopefully I will be back with some good news by tomorrow evening biggrin.gif

hey peeps, what voltage can one expect @5ghz ?

mine @ 4.8ghz is 1.365 volts.. but when i try 5ghz, I'm @1.5 volts and still freezing.. some of the core will not process prime tests.. doesn't throw any errors but will not complete a test.. is it safe to go above 1.5v for 5ghz?
