I gave my son my p5k-vm and some crucial 1066 tracer mem and other goodies and I was amazed at the clocks he's getting. 500 fsb with a e6420 @ 3.5 ghz. And, YES! it oc's the freakin memory bertter than my dluxe!!! he has it running @1200 with what it says is only 2.1v's! Quite a nice board I'll get him to post.
