4. Match the Pin-1 corners and insert the processor into the
socket. No force is required and the processor should drop into
place freely.
5. Swing the locking lever down and hook it under the catch on
the side of the socket. This secures the CPU in the socket.
6. All processors should be installed with a combination
heatsink/cooling fan, connect the cable from the fan to the
CPU fan power connector CPUFAN.

Install Memory

The mainboard has two 168-pin/184-pin DIMM sockets for
SDRAM/DDR (Double Data Rate) SDRAM system memory
modules. You must install at least one memory module in order to
use the mainboard, and you can only use one of the both
SDRAM and DDR SDRAM at the same time .
DDR SDRAM provides 800 MBps or 1 GBps data transfer
depending on whether the bus is 100 MHz or 133 MHz. It doubles
the rate to 1.6 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 reather than the 168-pin 3.3V unbuffered DIMMs
used by SDRAM.
For this mainboard, the maximum memory size is 1GB.
The edge connectors on the memory modules have cut outs, which
coincide with spacers in the DIMM sockets so that memory
module can only be installed in the correct orientation.
