2.
Identify the pin Pin-1 corner
on the CPU socket and the
pin Pin-1 corner on the
processor.
3.
Match the Pin-1 corners and insert the processor into the socket. Do not use
force.
4.
Swing the locking lever down and hook it under the latch on the edge of the
socket.
5.
Apply thermal grease to the top of the CPU.
6.
Lower the CPU fan/heatsink unit onto the CPU and CPU socket and then snap
then snap the fan/heatsink into place.
7.
Plug the CPU fan power cable into the CPU cooling fan power supply on the
mainboard (CPUFAN1).
Note:
After you have assembled the system, you must set the correct clock
speed and frontside bus (FSB) speed. Check the jumper section on page 8
for more information.
Installing Memory Modules
This mainboard accommodates 184-pin 2.5V Double Data Rate (DDR)
SDRAM and 168-pin 3.3V SDRAM memory modules. The memory chips must
be standard or registered SDRAM (Synchronous Dynamic Random Access
Memory).
The CPU supports 100MHz system bus. The SDRAM DIMMs and DDRs can
synchronously work with 100 MHz or operates over a 133 MHz system bus.
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 rather than the 168-pin 3.3V unbuffered
DIMMs used by SDRAM.
