Its a useful looking page, only problem here is that my Toshiba P200-1EE does have a memory controller listed as an Intel 965 chipset, but its got a ATI Radeon 2600 graphics card and a T5250 (1.5Ghz, 667Mhz front side bus) processor.
According to this guide the chipset comes with integrated graphics only, so I guess this guide is for the complete solution, I'm not sure if anyone knows but I'd like to find out if its possible on this laptop to upgrade the processor, either to one that supports a 800Mhz bus or one that keeps the 667Mhz bus (guessing the graphics card expects the memory to be 667Mhz, but don't really know).
