Specifications

2. Match the pin1 corner marked as the beveled edge

on the CPU with the pin1 corner on the socket.

Insert the CPU into the socket. Do not use force.

3. Push the locking lever down and hook it under the

latch on the edge of socket.

4. Apply thermal grease to the top of the CPU.

5. Install the cooling fan/heatsink unit onto the CPU,

and secure them all onto the socket base.

6. Plug the CPU fan power cable into the CPU fan

connector (CPUFAN1) on the mainboard.

Installing Memory Modules

This mainboard accommodates two 184-pin 2.5V unbuffered

Double Data Rate SDRAM (DDR SDRAM) Dual Inline

Memory Module (DIMM) sockets, and supports up to 2.0 GB

of 400 MHz DDR SDRAM.

DDR SDRAM is a type of SDRAM that supports data transfers on

both edges of each clock cycle (the rising and falling edges),

effectively doubling the memory chip’s data throughput. DDR

DIMMs can synchronously work with 133 MHz, 166 MHz or

200 MHz memory bus.

DDR SDRAM provides 1.6 GB/s, 2.1 GB/s or 3.2GB/s data

transfer rate when the bus is 133 MHz, 166 MHz or 200 MHz,

respectively.

DDR SDRAM uses additional power and ground lines and requires

184-pin 2.5V unbuffered DIMM module.
