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 sup-
plied. The form and size of fan/heatsink may also vary.
Installing Memory Modules
This motherboard accommodates two 240-pin unbuffered DDR2 SDRAM (Synchronous
Dynamic Random Access Memory) modules. It can support DDR2 800/667/533/400 memory
types and its total maximum memory size is 16 GB.
DDR2 SDRAM memory module table
Note: 1. When running dual channel mode, install only same (same density, DRAM
technology and DRAM bus width) module for each channel.
2. Please note that those types not in the TableB (p.17) will not boot up.
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.
