Hey everyone! I'm having issues with my Shuttle XPC SN45G running at 400mhz FSB. Everytime I set the FSB to 400mhz I get lockups and errors only when I'm playing games (currently HL2). I have an AMD AXP 2500+ oc'ed to 3000+ w/ 333mhz FSB right now. I also have kingston value ram 2x512mb DDR400. I never had an issue like this before only now and only when playing games. FYI i replaced my faulty stick of corsair before I had the kingston, so is my new memory at fault? Thanx in advanced for the help.
