The motherboard comes with two 240-pin Double Data Rate (DDR2) and
four 184-pin DDR Dual Inline Memory Modules (DIMM) sockets.
DDR2 DIMMS are notched differently to prevent installation on a DDR DIMM
socket.
The following figure illustrates the location of the sockets:

You may install 256 MB, 512 MB, and 1 GB unbuffered non-ECC DDR/DDR2
DIMMs into the DIMM sockets using the memory configurations in this
section.
• Always install DIMMs with the same CAS latency. For optimum
compatibility, we recommend that you obtain memory modules from
the same vendor.
• Due to chipset resource allocation, the system may detect less than
4 GB system memory when you installed four 1 GB DDR memory
modules.
• This motherboard does not support memory modules made up of
128 Mb chips or double sided x16 memory modules.
