Installing Socket 478 CPU Cooler Set 
As processor technology pushes to faster speed and a higher 
performance, thermal management becomes increasingly 
important. To dissipate heat, you need to attach the CPU cooling 
fan and heatsink on top of the CPU and we suggest that users 
should purchase Intel
®
 Boxed Cube Cooler for better heat 
dissipation. (Please refer to the image at the right hand). 
 
Follow the instructions below to install the Heatsink/ Fan: 
1. Locate the CPU and its retention mechanism on the motherboard. 
2. Position the heatsink onto the retention mechanism. 
3. Mount the fan on top of the heatsink. Press down the fan until its four clips get wedged 
in the holes of the retention mechanism. 
4. Press the two levers down to fasten the fan. Each lever can be pressed down in only 
ONE direction. 
5. Connect the fan power cable from the mounted fan to the 3-pin fan power connector on 
the board. 
Installing Memory Modules 
1. The memory module has only one notch on the center and will only fit in the right 
orientation. 
2. Insert the memory module vertically into the DIMM slot. Then push it in until the golden 
finger on the memory module is deeply inserted in the DIMM slot. The plastic clip at 
each side of the DIMM slot will automatically close when the memory module is 
properly seated. 
3. Manually check if the memory module has been locked in place by the DIMM slot clips 
at the sides.

Important: 
DDR2 memory modules are not interchangeable with DDR and the DDR2 standard is not 
backwards compatible. You should always install DDR2 memory modules in the DDR2 
DIMM slots. 
In Dual-Channel mode, make sure that you install memory modules of the same type and 
density in different channel DIMM slots. 
To enable successful system boot-up, always insert the memory modules into the DIMM1 
first.
