I have this motherboard with a Barton XP-M 2500+. My DDR is rated at 333mhz max. Now my setup is running at 166 * 12.5 (2083MHZ) @ 1.45V rock stable with a temp of 38C at full load wich is good. But the bios don't allow me to choose higher multi than that. I know that you can Bridge Mod CPU to get higher multi but I wonder if there's other way to do that, I don't want to mess with modding.... Wizza
