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.
