1.5.2Memory Configurations

You can install 128 MB, 256 MB, 512 MB, 1GB and 2GB DDR2 SDRAM DIMMs into the SODIMM sockets using the memory configurations in this section.

￿Installing DDR2 DIMM other than the recommended configurations may cause memory sizing error or system boot failure. Use any of the recommended configurations.

￿For dual-channel configuration, the total size of memory module(s) installed per channel must be the same (DIMM1 = DIMM2).

￿Always install DIMMs with the same CAS latency. For optimum compatibility, it is recommended that you obtain memory modules from the same vendor.

￿Due to chipset resource allocation, the system may detect less than 1 GB system memory when you installed one 1 GB DDR2 memory modules.

￿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.
