I was reading the specification of the MSI K7N2G-ILSR.
"Supports both 64-bit and 128-bit DDR SDRAM"
Can somebody explain to me the difference and what it means?

Marketing hype sort of. SDRAM modules use a data path that is 64 bits wide to connect to the memory controller in the north bridge. Nforce2 chipsets have 2 memory controllers providing 2 x 64 bit data paths but these connect to seperate 64 bit memory modules, not a single 128 bit one.
