Ok asus and gskill are a joke to get a hold of so I come here. I have a p5k board. I just got DDR2 PC6400 2x2GB. When I run WoW my comp freezes and I have to hit restart on my case. I have changed the timing in the bios the voltage the command rate and the mhz. It still freezes. My old ram works fine and this ram works fine unless I try and run Wow(old ram ran wow fine). Any suggestions?
