This motherboard only supports 4 banks of unbuffered DDR memory and 8 banks of registered DDR memory. Currently, Crucial 256 and 512MB DDR parts are double banked.The easiest way to identify the number of banks a module has is by counting the number of chips on the DIMM. Typically, DIMMs with 8 or 9 chips are single banked and those with 16 or 18 chips will be double banked.
