Memory configurations

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

Installing DDR DIMMs other than the recommended configurations may cause memory sizing error or system boot failure. Use any of the recommended configurations on the next page.

Install only identical (the same type and size) DDR DIMM pairs using the recommended configurations.

Make sure that the memory frequency matches the CPU FSB (Front Side Bus). Refer to the Memory frequency/CPU FSB synchronization table on the next page.

This motherboard does not support double-sided 16-bit DDR DIMMs.

Do not create a three-DIMM configuration in dual-channel mode. The third DIMM is ignored in the dual-channel operation.
