Overview

The motherboard comes with two 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 figure illustrates the location of the DDR2 DIMM sockets:

Memory configurations

You may install 256 MB, 512 MB, 1 GB, and 2 GB unbuffered non-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 next page

for details.

• Due to chipset resource allocation, the system may detect less than 4 GB

system memory when you installed two 2 GB DDR2 memory modules.

• This motherboard does not support memory modules made up of 128 Mb

chips or double sided x16 memory modules.

• If you install Window

®

XP 32-bit operation system, a total memory of less

than 3GB is recommended.
