2: Mainboard Installation
Installing Memory Modules
This mainboard accommodates 184-pin 2.5V unbuffered Double
Data Rate (DDR) SDRAM memory modules. The memory chips
must be standard or registered SDRAM (Synchronous Dynamic
Random Access Memory).
The CPU supports 100MHz system bus. The DDR DIMMs can
synchronously operate 100 MHz or 266 MHz system bus.
DDR SDRAM performs 800 MBps or 1 GBps data transfer
depending on whether the bus is 200 MHz or 266 MHz. It doubles
the rate to 1.0 GBps and 2.1 GBps by transferring data on both the
rising and falling edges of the clock. DDR SDRAM uses additional
power and ground lines and requires 184-pin 2.5V unbuffered
DIMM module rather than the 168-pin 3.3V unbuffered DIMMs
used by SDRAM.
