Installing the Motherboard
1 Install your CPU. Pull up the lever away
from the socket and lift up to 90-degree
angle.
2 Locate the CPU cut edge (the corner with the
pin hold noticeably missing). Align and insert
the CPU correctly.
3 Press the lever down and apply thermal
grease on top of the CPU.
4 Put the CPU Fan down on the retention
module and snap the four retention legs of
the cooling fan into place.
5 Flip the levers over to lock the heat sink in
place and connect the CPU cooling Fan
power cable to the CPUFAN connector. This
completes the installation.
CPU Installation Procedure
The following illustration shows CPU installation components.
To achieve better airflow rates and heat dissipation, we suggest that you use a
high quality fan with 4800 rpm at least. CPU fan and heatsink installation
procedures may vary with the type of CPU fan/heatsink supplied. The form
and size of fan/heatsink may also vary.
Do not remove any memory module from its antistatic packaging until
you are ready to install it on the motherboard. Handle the modules only
by their edges. Do not touch the components or metal parts. Always wear
a grounding strap when you handle the modules.
Installing Memory Modules
845PE-A800 accommodates two 184-pin 2.5V unbuffered Double Data Rate (DDR) SDRAM
(Synchronous Dynamic Random Access Memory) memory modules, and supports DDR400
(overclocking)/333/266 memory modules. Each module can be installed with 1GB of memory,
the total maximum memory size is 2 GB.
