• 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
conguration. 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 Qualied Vendors List on the next page
for details.
• If you install two 1 memory modules, the system may only recognize
less than 2GB because the address space is reserved for other critical
functions. This limitation appears on Windows® XP 32-bit operation system
which does not support Physical Address Extension (PAE).
• If you install Windows® XP 32-bit operation system, a total memory of less
than 2GB is recommended.
• This motherboard does not support memory modules made up of 128 Mb
chips or double sided x16 memory modules.
