Most enthusiast board will run "faster" if you know how to properly overclock the memory. Boards will never "officially" spec their board for a non certified speed, but if you want to tweak the board's BIOS settings, and get your RAM hopping as fast as possible, you buy a higher rate, and then overclock your memory bus to this increased bus speed, the memory should be able to handle the speed it was sold at (hence the higher speed designation) assuming the board can overclock it to that point.
DFI has one of the best memory overclocking (and processor overclocking for that matter) boards on the market.
Asus, Abit, MSI, Gigabyte, pretty much all of the tier1 and tier2 motherboard manufacturers have memory overclocking to some degree. Currently, DFI is the recognized leader.
