Basically I had my E6300 @ 2.8ghz. It was running fine for most of the day, but last night all games gave me error reports, had a blue screen pointing to ATI...I formated today - still there. Sometimes 3dmark 01 would run once then balls up. I played wow - got in fine, quit and got a bluescreen. Anyway - I took one stick out (2*512) and all *seems* good. Should I bother testing the seemingly faulty stick, or just try and RMA it?
