    OK, try these settings for 4Ghz. You will need to remove the 667Mhz memory (Kingstons).

    You may not be able to get 4Ghz, not all quads will do it.

    Ok I got it up to 3.8GHz and I'll get it to 4GHz when i get a new cooler. Thanks for your help. Here's a pic :D

    Looks good! So why no 4Ghz, too hot?

    Just wondered cause if that 3.8 is stable you should be able to do 4Ghz with your cooler cause voltages still look fairly low.

    I did a test with prime95 and pass . So I just tried 4GHz but when I save and exit bios my computer restarts twice and it go to 2GHz and when i enter bios it says stuff about wrong setting press any key to continue? What's wrong ? Is it the CPU Vcore because when i try it with 1.45V it stills happen and I don't wanna go any further and screw my CPU.

    It could be any setting really, that means the settings failed, and defaults are loaded no matter what it shows in the BIOS.

    Could be Vcore, what all did you change from 3.8 to 4Ghz? What settings fully for each one, then I can maybe see the problem. You can use more than 1.45 and your CPU will be fine, as long as temps are good, but especially should be fine for short testing anyway. Those CPU's are rated to 1.5 or 1.55 so you are good to try a bit more, but if you are unsure go ahead and give me the full settings you tried for 4Ghz as well as your full working 3.8 settings.

    I heard that if you raise CPU PLL it can fry your chip fast so that's why I left it on auto.

    For 4GHz, I just raised FSB to 450MHz.

    From what I have read you won't fry it but it may cause some damage so you won't be able to OC anymore.

    Howeven leaving it on auto is just as bad, BIOS will set it too high when you OC, you can check EasyTune -> Tuner -> Advanced -> Voltage tab for it's target value.
    Set it manually to 1.57v or 1.59v.
