Uh... well the problem is that the dividers can't divide the RAM base frequency to LESS than the CPU base frequency AFAIK. I THINK this is true for all P35 chipset motherboards, though I suppose someone may have a clever BIOS or hardware hack to make it work otherwise.
So if you need to run your CPU @ 400x9 = 3600, your RAM's MINIMUM speed is on a 1:1 divider, which means it ALSO runs at 400 MHz in this example.
So if you have GREAT confidence that your CPU AND Motherboard will hit like 500 MHz and above clock speeds (that's probably VERY optimistic in most realistic cases ), then there's maybe some reason to buy PC2-8000 DDR2-1000 memory which is guaranteed to run 500 MHz at stock timings / volts.
Anything much less than that and you might as well buy cheap but decent 400 MHz PC2-6400 RAM and you'll be able to run your CPU input clock at a speed equal to or in various steps less than 400 MHz and still keep the RAM running at 400 MHz with the dividers causing the CPU to be able to run at equal or LESS input clock speeds as the RAM. And of course a decent set of 400 MHz PC2-6400 RAM will usually overclock at least to around 425 if not in many cases well above that sometimes even up to 450, maybe 500 MHz with loosened timings......
