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 identical

identical identical

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.
