The motherboard comes with four 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. DDR2 DIMMs are notched to match the break on the
socket and ensure correct installation.
The figure illustrates the location of the DDR2 DIMM sockets:

You may install 256 MB, 512 MB and 1 GB registered ECC DDR2 DIMMs into
the DIMM sockets.
• Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules
from the same vendor. Refer to the DDR2 Qualified Vendors List on
the ASUS website (www.asus.com) for details.
• This motherboard does not support memory modules made up of
128 Mb chips or double sided x16 memory modules.
