sorry to go off topic :
Retro either 1) RMA your board or 2) try other ram (P45 is very picky) or 3) come to the P5Q thread and share ya settings... something is wrong and for me the P5Q dlx is an incredible stable board... a solid workhorse... don't think another CPU will help in your case...

I would upgrade to an E8400 CPU mate instead of buying a new mobo... unless you want a new toy to play with
