a metal object, such as the power supply case, before handling
components to avoid damaging them due to static electricity.
• Hold components by the edges to avoid touching the ICs on them.
• Whenever you uninstall any component, place it on a grounded
antistatic pad or in the bag that came with the component.
• Before you install or remove any component, ensure
that the ATX power supply is switched off or the power cord is detached
from the power supply. Failure to do so may cause severe damage to the
motherboard, peripherals, and/or components.

will not t in completely.
2. Unlock the socket by pressing the
lever sideways, then lift it up to a
90º angle.
2.3 Central Processing Unit (CPU)
The motherboard comes with a 940-pin AM2 socket designed for the AMD Athlon™
64/AMD Athlon™ 64 FX/AMD Athlon™ 64 X2 and AMD Sempron™ processors.
Socket lever
The AM2 socket has a different pin layout from the 940-pin socket designed for
the AMD AM2 processor. Make sure you use a CPU is designed for the AM2
socket. The CPU ts in only one correct orientation. DO NOT force the CPU into
the socket to prevent bending the connectors on the socket and damaging the
CPU!
