1.4 Before you proceed
Take note of the following precautions before you install motherboard components or change
any motherboard settings.
• Unplug the power cord from the wall socket before touching any component.
• Before handling components, use a grounded wrist strap or touch a safely grounded
object or a metal object, such as the power supply case, 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, switch off the ATX power supply and
detach its power cord. Failure to do so may cause severe damage to the motherboard,
peripherals, or components.

M4A88T-M CPU Socket AM3
This motherboard comes with an AM3 socket designed for Phenom™ II / Athlon™ II /
Sempron™ 100 series processors.
The AM3 socket has a different pinout from the AM2+/AM2 socket. Ensure that you use a
CPU designed for the AM3 socket. The CPU ts in only one correct orientation. DO NOT
force the CPU into the socket to prevent bending the pins and damaging the CPU!
1.6.1 Installing the CPU
To install a CPU:
1. Locate the CPU socket on the motherboard.
2. Press the lever sideways to unlock the
socket, then lift it up to a 90°-100° angle.
Ensure that the socket lever is lifted up to a 90°-100° angle; otherwise, the CPU will not t
in completely.
3. Position the CPU above the socket such that the CPU
corner with the gold triangle matches the socket corner
with a small triangle.
4. Carefully insert the CPU into the socket until it ts in place.
The CPU ts only in one correct orientation.
DO NOT force the CPU into the socket to
prevent bending the pins and damaging the
CPU!
