Ghost, i think you can get your FSB as high as 450 using the 333/1333 reference clocks. beyond that, you might have to use 400/1600.

GTJ and Anubi, thank you very much. especially GTJ. without you, i probably would have thrown my BT in the trash a long time ago. i'll try the black slots and renew my efforts to hit DDR 1800 memory. i had just begun to accept DDR 1500, even though i wasn't terribly happy about it.
