    Ahh, maybe he just gave the wrong settings to us then? I think he says XMP on though, right?

    You go ahead and help him though since you have been already and I will step aside :)

    That way I don't confuse things anymore

    I specifically asked if XMP is disabled or not.
    BTW it's easy to see if auto selects the right multiplier, there are no maching miltipliers for 800 and 1066 for 333MHz in the other straps.

    XMP is disabled.

    Your board may need the lower MCH, just trying to see if that is for sure or not.

    Also, set your own Memory mutliplier so you know Auto is not setting an incorrect one. For 333 FSB to run 1066 Memory set 3.20B
    I set CPU Termination to 1.220V and my computer still froze, I also tried increasing the MCH core but if I go above 1.050V my computer becomes more unstable. Should I try decreasing the MCH core from 1.050V?
    Also tried to use 3.20B but my computer still froze (after 3 minutes).

    If XMP is disabled and memory is running at 1066 (533MHz in CPU-Z Memory tab) I strongly recommend to clear CMOS, 20-30 minutes clear with jumber on CLR_CMOS pins and the battery out. If this is not enough, leave it like that for 6-8 hours/overnight. Read the second parf of this post.
    This is not the normal behaviour for this setting, and if this does not work as it should maybe other things too.

    Yes, I have seen users that had to use 0.95v to get stable.

    I too have seen a few boards need less than stock MCH, it's just not all that common is why I was wanting you to try a few more things before you are sure you have one of these boards.

    Last thing I would suggest you try before you decide you need less than the norm, is try putting your memory in the other channels using slots 2+4 instead of 1+3 or visa versa if you are already using 2+4

    I cleared my CMOS and changed the RAM to the other slots, my computer didn't freeze for 40 minutes now, I'm going to try lowering the MCH Core voltage.

    edit: never mind, I can't even access my OS anymore, verifying DMI doesn't succeed( I don't think it did before either) and it endlessly says that windows did not start normally, my computer just blue screens really fast at the end and restarts.

    Clear your CMOS fully as mentioned in post #2 here
    http://forums.tweaktown.com/f69/bios...h-guide-27576/

    If that does not help then try only one stick of ram after clearing the CMOS AGAIN, if that does not help try putting the memory back in the other slots and clearing it again.

    Then of course you do have to set your SATA mode again to the same you were using before, and then go into Hard Disk Boot Priority and move your disk by name to the top of the list if it is not already.

    I did that, turns out it was actually the OS that was unstable, I reinstalled my OS and everything is fine now. Thanks to everybody that helped me.
