2.4.1 Overview
The motherboard comes with two Double Data Rate 2 (DDR2) Dual Inline Memory
Modules (DIMM) sockets.
The figure illustrates the location of the DDR2 DIMM sockets:
2.4.2 Memory configurations
You may install 128 MB, 256 MB, 512 MB , and 1024 MB unbuffered non-ECC
DDR2 DIMMs into the DIMM sockets.
Channel Sockets
Channel A DIMM_A1
Channel B DIMM_B1
• 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. Refer to the DDR2 Qualified Vendors List on the next page
for details.
• If you are using a Windows 32-bit version operating system (e.g. 32-bit
Windows, 32-bit Vista) without the Physical Address Extension (PAE)
support, the system will allocate a certain amount of memory space for
system devices.
• This motherboard does not support memory modules made up of 128 Mb
chips or double sided x16 memory modules.
