Hardware Setup

2-5

The mainboard provides two 184-pin DDR DIMM (2.5V) with 4 memory banks.

To operate properly, at least one DIMM module must be installed.

You can install two PC1600/PC2100 DDR SDRAM modules on the DDR DIMM

slots (DDR 1~2).

DDR (Double Data Rate) SDRAM is similar to conventional SDRAM, but

doubles the rate by transfering data twice per cycle. It transfers data on both

the rising and falling edges of the clock. Conventional SDRAM only uses the

rising edge of the clock to transfer data.

DDR SDRAM 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.

Two types of DDR are available at the time of writing: PC1600 & PC2100.

PC1600 DDR SDRAM running at 100MHz will produce about 1.6GB/s memory

bandwidth. PC2100 running at 133MHz will produce 2.1GB/s memory bandwidth.
