2.4.1 2.4.1 2.4.1 2.4.1 2.4.1 Overview Overview Overview Overview Overview
The motherboard comes with six Double Data Rate 2 (DDR2) Dual Inline Memory
Modules (DIMM) sockets.
A DDR2 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, 1 GB, and 2 GB registered ECC DDR 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 at
the ASUS web site.
• Due to chipset resource allocation, and depending on the number of
expansion cards installed, the following conditions may occur:
- the system may detect less than 8 GB system memory when
you installed four 2 GB DDR2 memory modules
- may show an available memory space of less than 4 GB when
you installed four 1 GB DDR2 memory modules
• Three DDR DIMMs intalled into any three memory sockets will
function in single-channel mode.
• If you are installing only one memory module, install into the blue
socket labeled DDR_A3 or DDR_B3. Installing into any other socket
would not work.
