1.5.2 Memor y Configurations
You can install 256MB, 512MB, 1GB and 2GB DDR2 SDRAM DIMMs into the SODIMM
sockets using the memory configurations in this section.
z Installing DDR2 DIMM other than the recommended
configurations may cause memory sizing error or system boot
failure. Use any of the recommended configurations.
z For dual-channel configuration, the total size of memory
module(s) installed per channel must be the same (DIMM1 =
DIMM2).
z Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules
from the same vendor.
z Due to chipset resource allocation, the system may detect less
than 1 GB system memory when you installed one 1 GB DDR2
memory modules.
z This motherboard does not support memory modules made up of
128 Mb chips or double-sided x16 memory modules.
Make sure that the memory frequency matches the CPU FSB
(Front Side Bus). Refer to the Memory frequency/CPU FSB
synchronization table.
