The Installation of LGA 775 CPU & CPU Cooler
1. The CPU has a plastic cap on it to protect the
contact from damage. Before you have installed
the CPU, always cover it to protect the socket
pin.
4. Open the load lever.
7. Visually inspect if the CPU is seated well into
the socket. If not, take out the CPU with pure
vertical motion and reinstall.
10. Align the holes on the mainboard with the
heatsink first. Push down the fan/heatsink un-
til its four clips get wedged into the holes of
the mainboard.
MSI Reminds You...
1. Confirm if your CPU cooler is firmly installed before turning on your system.
2. Do not touch the CPU socket pins to avoid damaging.
3. Whenever CPU is not installed, always protect your CPU socket pin with the plastic cap covered (shown in
Figure 1) to avoid damaging.
4. Please note that the mating/unmating durability of the CPU is 20 cycles. Therefore we suggest you do not
plug/unplug the CPU too often.
