Or else it won't work. Supplying data sooner is usually OK.
Ok I will try to keep this short.
If your main board only has a 256 FSB can you still use
DDR400 ram or will it not work?
If your main board supports a 400mhz FSB but, you are running a 266 CPU bus can you still use DDR400 or will
it also not work in this situation?
I guess the real question is must bus speeds between the processor and the memory match?
