• 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.
