Very interesting. I also can't overclock on my board anymore as well. My PC won't cold boot at even very mild overclocked speeds (20x150).

Although still, even a mild OC will randomly power cycle my machine anymore...

I was about to RMA my memory, but I may try and borrow some from a friend this weekend to rule that out. If my tests

PS - It is not a failed PSU. I've checked with a known working one.

i just let it without any overclock, i've tested the ram with memtest 4.0 default and under overclock and it has no problem as long the cpu is on default setting, it must be some sort of incompatibility, i really can't figure this issue out, my psu is a brand new enermax pro82+ 525w , i only have a 9800gt vga so i don't need more than this.
