The motherboard comes with four 240-pin Double Data Rate 2 (DDR2) Dual
Inline Memory Modules (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 DIMM. 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 DDR2 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 in Table 1.
• In dual-channel configurations, install only i d e n t i c a l i d e n t i c a l i d e n t i c a l i d e n t i c a l i d e n t i c a l (the same
type and size) DDR2 DIMM pairs for each channel.
• Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules
from the same vendor.
• Due to chipset resource allocation, the system may detect less than
4 GB of system memory when you installed four 1 GB DDR2 memory
modules.
• Due to chipset limitation, 128 MB or double-sided x16 memory
modules are not supported in this motherboard.
