Memory Configurations - Asus V-Series P5G31 Installation Manual

2.5.1 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.
• If you install two 2GB memory modules, the system may only recognize less
than 3GB because the address space is reserved for other critical functions.
This limitation appears on Windows
not support Physical Address Extension (PAE).
• If you install Windows
than 3GB is recommended.
• This motherboard does not support memory modules made up of 128 Mb
chips or double sided x16 memory modules.
