    E8500 max voltage

    Hi there ;
    After reading many post . Most people suggest to stay bellow 1.35 v as safe voltage .
    However, I don't need my chip for more than 6 months .
    What should be the voltage then ???.
    1.5 v is good enough ??

    thanks,

    well i have runned mine with almost 2.0v with a cascade so i would say if you have the cooling power go for it 1.65v with air cooling is pretty much the max i would imagine. after that most coolers loose there ability to transfer heat away from the cpu..

    I would stick around 1.4-1.45 on air or water for daily use... 1.65 max for benching...
    Question : Why do some overclockers switch into d*ckmode when money is involved

    Remark : They call me Pro Asus Saaya yupp, I agree

    Killing the chip will probably not happen at sub-1.55v if the chip doesn't run too hot (which is the max you'd ever want to use anyway because more yields pretty much no extra overclocking). The only thing you risk when using 1.35v is degradation in maximum overclock and a lower overclock at a specific vcore. I'd say 1.35v is pretty safe and if you encounter any degradation just up the vcore by a tad or lower the clock until it regains stability. For 6 months use I'd suggest to not hold back too much

    so 1.4-1.45 on water will kill the chip on 6 month ????? .

    I would say 1.4v, maybe 1.45v with 45nm cpus, we still don't know whether they can tolerate the same voltages 65nm cpus could even though they run cooler (mainly because of high k+mg)

    do u talk about the max safe voltage range or the max voltage for 6 month run .

    Why does your sig say ''CRAPPY'' e8500 @ 4.7GHz with 1.45v? are you insane dude lol...

    My E8400 needs 1.38v underload just to do 4GHz stable (granted it used to do it with 1.34v, but degradation happened) i would never complain about 4.2GHz even at 1.4v underload. lol your a crazy guy

    1.38? Wow. I hope my 8500 doesn't degrade. It's doing 4GHz on 1.25 but it runs near 70C too under prime. Gotta water cool it. Until I do, I just might step things down to 3800.

    . I forget to remove the world crappy after signature update.
    The crappy processor was An E6600 @ 3.2 Ghz (not stable @ higher frequency even with 1.8 v)
