Hey, you and I have almost identical systems. How did you OC your CPU so high? I heard that an Athlon 2500 will OC to 2800 speeds with the stock heatsink. When I change my CPU multiplier to 12.0 I get crazy results, like XP won't load or everything crashes, even after I raise the core voltage a little bit. Also, on my Asus board I can't set the bus speed by 1MHz increments, only by 33MHz increments.. I don't get it.
