Just recently got my xp3200 barton with asus a7n8x-e deluxe, with 2 512 ddr 400 mhz ram. Seems to be unstable with a 200 fsb setting in my bios, especially when starting a game. Most of the time it shuts down and reboots. If I change my fsb setting in bios to 166 instead of 200, wich now turns my 3200 into a 2500 , everything runs fine and is very stable. Any ideas as to how to correct this problem.
