1.5.2 Memory
Configurations
You can install 128 MB, 256 MB, 512 MB, 1GB and 2GB DDR2 SDRAM DIMMs into the
DIMM 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.
