Well i just got an asus P5N-e sli mobo and i have a pentium 4 640 oced from 3.2 to 3.8 and idleing at 40C. The problem i have is that i can't install more than 1 stick or ram or i get blue screen of death at startup. I have 533 pc4200 ram. I have 1x1gb stick and 2x512 sticks. i am just running the 1gig one right now. If i add the other two after windows loading screen i get blue screen of death. Any ideas as to why or how i can use all of my ram? i tried the ram on other computers and it works.. just not on my board.
