    I ran memtest86 for about 2 hours (2 full cycles) with no errors, and system stability tester for 45 min~ using 64m pi digits, no errors either.
    I can understand prime95, If I run blend test, after about 45 minutes the system reboots, leaving no logs of were or if it did fail.
    The only weird thing was after shutting down normally windows, next day when I turn on again the pc rebooted 2 times before bios, bios settings were default again. That happened just one time (can't understand why) now I turn off an on again with no problems

    Try the following.
    Where ranges or more than one value specified you need to check which is most stable for you.
    Only make one change at a time.
    Prime95 log is in results.txt in the same directory. If the machine crashed the value that caused it is the one that comes after the last successful test, you may scroll back and see what it was.

    no good at 400x7.5 or changing some parameters like you said, I loaded the last "stable" settings that I've mentioned and now wont even boot... I get triple reboot plus a repetitive beep comes out(WTF) the settings that worked this afternoon now they dont anymore.. FUNNY
    Im starting to believe that no good can come if I keep playing with this haha

    Have you tried both 4.00B and 4.00D multipliers?
    Try with 3.33D timings 8-8-8-24 and MCH Reference auto.
    If you crash/BSOD the error code may help too, you can find it in the evemt log.

    this may help you for Prime 95 errors...

    Small FFT
    This test uses data that fits completely into your CPU's level 2 cache, it stresses the processor intensely but does not stress the RAM or the link between the RAM and the processor. It will error out because of:
    Not enough vCore
    Possibly low CPU Termination (VTT)
    Possibly low/high CPU ref
    Possibly low PLL (clock generator) voltage

    Large FFT
    This test uses large "pieces" of data that require information to be moved in and out of RAM quite intensely to constantly feed the processor. The data in these calculations doesn't fit completely in CPU onboard cache, so the work load on the MCH and RAM is huge. It will error out because of:
    Not enough vDIMM (RAM voltage)
    Not enough (and rarely too much) MCH core voltage
    Incorrect MCH ref voltage
    Unstable memory timings (includes both main timings ie 5-5-5-15, and also tRead and tRFC.
    Only fails because of processor when vCore is waaaaaay too low!

    Blend
    This alternates between small and large data sets, and although it is a useful "last test" when run for say 24 hours after you believe you have everything dialed in and it passes Large and Small seperately, it's confusing for fault finding.
    If Blend fails it could be for any reason mentioned for small FFT and large FFT leaving you with no indication what to do to stablise the system.

    thanks for the help. getting an stable OC is being more dificult than just buying a new pc! haha Every time I change just one of those settings a new issue appear: now my windows won't boot, in the loading windows screen the pc reboots but in the M.I.T doesnt appear the error in red letters..
    Thats enough for today..

    Welcome to the world of Overclocking. It can be a long process, not for the ill fanted.

    Hey ugh the corsair memory is it dual or tripple channel ddr3? Also you may need to reset your CMOS after all your testing. Your full system specs in your sig would help greatly so we know wot were dealing with. Guessing wot you have is a disadvantage for all.

    Also IMO you may be taking the wrong approach in your OC. If were me ( and I'm no expert @ overclocking) I would 1st find my highest memory MHz at the lowest fsb and multi and go from there. I know there are a lot of knowledgeable peeps here to help you out. The 8 GB memory may also be a problem IMO.

    Another approach I might take is to search your mother board model and 8 gigs memory.

    Buying a new CPU/motherboard is always easier, but some of us like to get more of what they bought anyway.
    Keep in mind that entering settings that fail and trting a completely new settings won't bring you anyway.
    Identifieyin the problem and adjust settings accordingly one by one is the right way.
    Also stating "I tried those settings" does not help us to help you, be more specific, what settings have yoy tried what have you changed and what made difference for better or worse.
