    But it is now set to Normal, which is 1.12500, is this fine for 3.33GHz, if the linx is stable? mm67 set 1.225 vcore for 4.2GHz, so I think this is kinda fine.
    I will test with 3072MB, but there was not enough free physical ram for that.

    No he had 1.36v in CPU-Z at 4.2GHz.
    If GFlops are as expected, run Prime95 blemd for 6-8 hours, if it doesn't fail or crash than it should be good.

    That old screenshot was done with LLC off, on full load Vcore drops to 1.296 V. Normally I use 1.3375 V in bios with LLC on which also shows same 1.296 V in Cpu-Z.

    With the vcore set to Normal, I run prime and the computer restarted :(

    Now I changed the Normal to 1.1250 and x264 encode is in progress (it takes about 4-5 hours to test).
    Then I will start prime95 to see if the computer is stable with 1.1250 or it will restart again (I run it for 30-40 mins before shutting prime down, till that it was fine).

    Temps are much better anyway with applying the new thermal paste and setting up the vcore from Auto to manual, the question is if 1.1250 will be enough for stable 3.33GHz :)

    If default is 1.125v there is no point setting it to the same value manually.
    Try 2-3 clicks higher.

    At the moment the prime is running and vcore is on 1.1250, everything is fine, I will check if the prime is still running in the morning.
    If there will be no problem with prime on vcore 1.1250 should I stay on this voltage or safer to set it 1-2 clicks higher ?

    Yes, stay as it is if Prime95 pass good 8+ hours blend.
    If you experiance BSODs or craches in the future you can try and add 2-3 clicks.

    My computer restarted on 1.1250 and on 1.1375 too, now the prime is running on 1.14xx, I hope this will be enough.
    The point is the more the vcore is, the longer the prime is stable and run.

    update: it restarted (and crashed with blue screen :F ) on 1.14375 too after approx. 7 hours of prime running, I had to increase the vcore with one step again, I hope this will be really enough, coz the prime almost was able to be run for 8 or more hours.

    Now I will leave it for at least 9-10 hours to see if it is really stable.

    My computer restarted on 1.1500 vcore too :|
    @Chike: I raised the vcore to 1.1625 now, prime is running again. Is it normal that the prime makes the computer crash/restart after x hours ? Or if the vcore is set properly, then the prime should run for days, weeks.. etc ?

    Yes, it is usually a specific FFT size that will cause it.
    To shorten the test you must find the FFT size that caused reboot.
    In the log(results.txt) you can only find the last FFT that passed successfully, the FFT you need is the one after that.
    If you can find that size back in the log from a successful test you can enter it as min/max FFT and run only that size, which hopefully will crash in just few minutes.

    It may be that it is not vcore that is the reason for crash. Perhaps you need more VTT or to rweak the references.
