    I ran OCCT Linpack on the OC in my specs and failed after 46 mins. In trying to figure out which component was unstable, I dropped my cpu to 2.5GHz and kept my memory at 1GHz and tested again--passed for 6 hours. I increaced my CPU voltage and am going to have to run OCCT again tonight.

    It is stable but it aborting due high temp. I have to change 12mm fans on my CPU.
    That would be no.

    My 3.6GHz clocks are stable, but the 4.0GHz takes way to much voltage and gets way to hot for me to let it run for more than an hour. If I was on water I wouldn't worry.

    Agreed...My 3.6 on my PHII is stable, but 3.9 took to much voltage. But to answer the original questions...My 3.6 is stable as a rock at 1.42 volts.

    I think OCCT hates Win 7. Even with a stable OC, I always get errors on the 8-9 min mark and in multiples. So, if it makes it 8-9 min, next time I a chance for a error is not until the 16-17 min mark. Its constant too.

    Question: Does anyone know if there is any truth that if you error out and see excessive fluctuation on the 3.3, 5, or 12 volt charts that you need to increase the vMCH and if you see it on vCore that you need to increase VTT or PLL?

    I had seen someone comment this over on the Anandtech board while doing a google search once.

    Both my 3.6Ghz and 3.8Ghz settings are 2 hour stable, which both are under 1.3v vcore. I havent tried 4 hr+ yet.

    So far, the highest stable OC i have managed to reach on this chip is 4.10Ghz- 8.5X480 1920Mhz FSB and a 1:1 ratio on the RAM:CPU (961Mhz) I have gone as far as 4.525Ghz on this chip but I cant seem to get it stable past 4.10.. and when I mean stable... Im talking about at least a 7hour OCCT Linpack (over night while sleeping lol)

    My 3GHz is 6hr stable in Linpack. However my RAM is at it's wits end... won't do 520MHz.

    I only ever test for 1 hour, if it plays all my games and does everything else I want without a failure then it's stable.
