3.5 System Memory
This motherboard features two Double Data Rate (DDR) Dual Inline Memory Mod-
ule sockets and three Single Data Rate (SDR) Dual Inline Memory Module sockets.
3.5.1 DDR DIMM Support
The two DDR DIMM sockets support 2.5Volt (power level) unbuffered/registered
Double Data Rate Synchronous Dynamic Random Access Memory (DDR SDRAM)
of 64MB, 128MB, 256MB, 512MB, and 1GB to form a memory size between 64MB
to 2GB. One side (with memory chips) of the DIMM takes up one row on the
motherboard.
DDR DIMMs support non-ECC modules that are available in both registered
(typically used in servers) and unbuffered (typically used in PCs) versions.
NOTE: The DDR memory bus runs at the same frequency as the CPU front side bus.
Install memory in any combination as follows:
