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.
• 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.
