    Try switching to 2.0D memory multiplier. If that doesn't work, try backing off FSB to 425. You might be overclocking memory too much.

    Thanks for the reply, for some reason with 2D my pc continues to reboot and with the F6 BIOS same settings it was completely stable. May need to flash back the BIOS

    Well, I just tried the F7 bios as well. There goes my stability. I'm not happy at all. Now I have to reconfigure, tweak, and test again. I might just flash back to the F6 as you point out. Jeez!

    Haven't played around with f5 to much. Finally got it stable (f7) just had to increase my MCH one notch 6 loops of intel burn test. Gonna do more loops tonight when its a little bit cooler

    Not sure if F6 is better than F5 because I didn't even start overclocking until F6.

    I've actually found that decreasing MCH Vcore gets my stability back in check. Go figure!

    Yeap, P45 is very tricky about voltages when it comes to the MCH and the strap in use. So play around with it a bit if you have issues on a certain strap as sometimes less is better when you would think more is needed.

    MCH Ref and Vtt also play a huge part in stability, so keep that in mind as well
