System memory
The motherboard comes with two Double Data Rate2 (DDR2) Dual Inline
Memory Module (DIMM) sockets.
A DDR2 module has the same physical dimensions as a DDR DIMM but has a
240-pin footprint compared to the 184-pin DDR DIMMs are notched differently
to prevent installation on a DDR DIMM socket.
The figure illustrates the location of the DDR2 DIMM sockets.

Memory configurations
You can install 128 MB, 256 MB, 512 MB, and 1GB DDR SDRAM DIMMs into
the DIMM sockets using the memory configurations in this section.
• Installing DDR2 DIMMs other than the recommended configurations
may cause memory sizing error or system boot failure. Use any of
the recommended configurations on the next page.
• Install only identical (the same type and size) DDR2 DIMM pairs
using the recommended configurations.
• Make sure that the memory frequency matches the CPU FSB
(Front Side Bus). Refer to the Memory frequency/CPU FSB
synchronization table on the next page
• Due to chipset resource allocation, the system may detect less
than 2 GB system memory when you installed two 1 GB DDR2
memory modules.
• This motherboard does not support memory modules made up of
128 Mb chips or double sided x 16 memory modules.
