2-3 CPU Installation

This motherboard provides an AM3+ socket that supports compatible AMD

AM3/AM3+ processor.

The CPU that comes with the motherboard should have a cooling FAN attached to

prevent overheating. If this is not the case, then purchase a correct cooling FAN

before you turn on your system.

WARNING!

Be sure that there is sufficient air circulation across the processor's

heatsink and CPU cooling FAN is working correctly, otherwise it may

cause the processor and motherboard overheat and damage, you

may install an auxiliary cooling FAN, if necessary.

To install a CPU, first turn off your system and remove its cover. Then find Pin-1

(small triangle indicator) of the CPU and make sure to install it matched with Pin-1

(small triangle indicator) of the CPU socket. See to it that system is turned off and the

installation direction is correct. If the installation direction is wrong, CPU can not be

installed into the socket. In this case do not try to force it into the socket, but to change

to the correct direction.
