1.7.2 Memory configurations
You may install 512MB, 1GB and 2GB 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. Refer to the DDR2 Qualified Vendors List on the next page
for details.
• When installing total 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.
