is is a Micro ATX form factor motherboard. Before you install the motherboard,
study the conguration of your chassis to ensure that the motherboard ts into it.
Pre-installation Precautions
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
• Make sure to unplug the power cord before installing or removing the motherboard
components. Failure to do so may cause physical injuries and damages to motherboard
components.
• In order to avoid damage from static electricity to the motherboard’s components,
NEVER place your motherboard directly on a carpet. Also remember to use a
grounded wrist strap or touch a safety grounded object before you handle the
components.
• Hold components by the edges and do not touch the ICs.
• Whenever you uninstall any components, place them on a grounded anti-static pad or
in the bag that comes with the components.
• When placing screws to secure the motherboard to the chassis, please do not over-
tighten the screws! Doing so may damage the motherboard.

2.1 Installing the CPU
1. Before you insert the 1700-Pin CPU into the socket, please check if the PnP cap
is on the socket, if the CPU surface is unclean, or if there are any bent pins in the
socket. Do not force to insert the CPU into the socket if above situation is found.
Otherwise, the CPU will be seriously damaged.
2. Unplug all power cables before installing the CPU.

2.3 Installing Memory Modules (DIMM)
is motherboard provides four 288-pin DDR5 (Double Data Rate 5) DIMM slots,
and supports Dual Channel Memory Technology.

1. For dual channel conguration, you always need to install identical (the same
brand, speed, size and chip-type) DDR5 DIMM pairs.
2. It is unable to activate Dual Channel Memory Technology with only one or three
memory module installed.
3. It is not allowed to install a DDR, DDR2 , DDR3 or DDR4 memory module into a
DDR5 slot; otherwise, this motherboard and DIMM may be damaged.
4. e DIMM only ts in one correct orientation. It will cause permanent damage to
the motherboard and the DIMM if you force the DIMM into the slot at incorrect
orientation.
