1.7 System memory
1.7.1 Overview
The motherboard comes with four Double Data Rate 2 (DDR2) Dual Inline Memory
Modules (DIMM) sockets.
The figure illustrates the location of the DDR2 DIMM sockets:
1.7.2 Memory configurations
You may install 256 MB, 512 MB, 1 GB and 2 GB unbuffered non-ECC DDR2
DIMMs into the DIMM sockets.
• You may install varying memory sizes in Channel A and Channel B. The
system maps the total size of the lower-sized channel for the dual-channel
configuration. Any excess memory from the higher-sized channel is then
mapped for single-channel operation.
• Always install DIMMs with the same CAS latency. For optimum compatibility, it
is recommended that you obtain memory modules from the same vendor.
• When installing total memory of 4GB capacity or more, Windows 32-bit operation
system may only recognize less than 3GB. Hence, a total installed memory of
less than 3GB is recommended.
• This motherboard does not support memory modules made up of 128 Mb
chips.
