2.3 Memory
The mainboard provides two 184-pin unbuffered DDR333/DDR400 DDR
SDRAM, and supports the memory size up to 2GB without ECC. To oper-
ate properly, at least one DIMM module must be installed.

Introduction to DDR SDRAM
DDR (Double Data Rate) SDRAM is similar to conventional SDRAM, but
doubles the rate by transferring data twice per cycle. It uses 2.5 volts as
opposed to 3.3 volts used in SDR SDRAM, and requires 184-pin DIMM
modules rather than 168-pin DIMM modules used by SDR SDRAM.
