You should always run the FSB and memory bus in sync for best performance.
So if you can only get 166MHz out of your memory, keep the FSB to 166MHz.
Of course 200MHz for both would be a little better.

There aren't any 400Mhz rams on the market. PC3200 is 200MHz. Talking
actual bus speed here, not data rate, DDR400. The memory bus and FSB
should have the same clock speed, 166MHz, 200MHz, or whatever.
