Safety Information
Electrical safety
To prevent electrical shock hazard, disconnect the power cable from the electrical outlet
before relocating the system.
When adding or removing devices to or from the system, ensure that the power cables
for the devices are unplugged before the signal cables are connected. If possible,
disconnect all power cables from the existing system before you add a device.
Before connecting or removing signal cables from the motherboard, ensure that all
power cables are unplugged.
Seek professional assistance before using an adapter or extension cord. These devices
could interrupt the grounding circuit.
Make sure that your power supply is set to the correct voltage in your area. If you are not
sure about the voltage of the electrical outlet you are using, contact your local power
company.
If the power supply is broken, do not try to fix it by yourself. Contact a qualified service
technician or your retailer.

Chapter 1 - Product Introduction
1.1 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.
Use a grounded wrist strap or touch a safely grounded object or 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
anti-static pad or in the bag that came with the component.
Before you install or remove any component, ensure that the
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.
1.2 Motherboard Overview
Before you install the motherboard, study the configuration of your chassis to ensure that the
motherboard fits into it. Refer to the chassis documentation before installing the motherboard.
Make sure to unplug the power cord before installing or removing the
motherboard. Failure to do so can cause you physical injury and
damage motherboard components.
1.2.1 Placement Direction
When installing the motherboard, make sure that you place it into the chassis in the correct
orientation. The edge with external ports goes to the rear part of the chassis as indicated in
the image below.
1.2.2 Screw Holes
Place four (4) screws into the holes indicated by circles to secure the motherboard to the
chassis.
Do not over tighten the screws! Doing so can damage the
motherboard.

1.3 Central Processing Unit (CPU)
The motherboard comes with a surface mount LGA1151 socket designed for the Intel®
Core™ i7/ i5/ i3 processor in the 1151-land package.
Your boxed Intel® Core™ i7/ i5/ i3 LGA1151 processor package
should come with installation instructions for the CPU, fan and
heatsink assembly. If the instructions in this section do not match
the CPU documentation, follow the latter.
Upon purchase of the motherboard, make sure that the PnP cap
is on the socket and the socket pins are not bent. Contact your
retailer immediately if the PnP cap is missing, or if you see any
damage to the PnP cap/socket pins/motherboard components.
XXXXXX will shoulder the cost of repair only if the damage is
shipment/transit-related.
Keep the cap after installing the motherboard. XXXXXX will
process Return Merchandise Authorization (RMA) requests only
if the motherboard comes with the cap on the LGA1151 socket.
The product warranty does not cover damage to the socket pins
resulting from incorrect CPU installation/removal, or
misplacement/loss/incorrect removal of the PnP cap.
Install the CPU fan and heatsink assembly before you install
motherboard to the chassis.

MX370QD User’s Manual
MX370QD User’s Manual
17
If you purchased a separate CPU heatsink and fan assembly,
make sure that you have properly applied Thermal Interface
Material to the CPU heatsink or CPU before you install the
heatsink and fan assembly.
To support i7 CPU, we suggest to use at least 150w adapter or
above. For i5 CPU, 120w or above is suggested.
1.3.1 Installing the CPU
1. Locate the CPU socket on the motherboard.
Before installing the CPU, make sure that the socket box is facing
towards you and the load lever is on your left.
2. Press the load lever with your thumb (A), then move it to the left (B) until it is released
from the retention tab.

B
Retention tab

MX370QD User’s Manual
18 MX370QD User’s Manual
To prevent damage to the socket pins, do not remove the PnP cap
unless you are installing a CPU.
3. Lift the Load lever with your thumb and forefinger to around 180º angle (A), then pull the
PnP cap from the CPU socket to remove (B).
4. Position the CPU over the socket, making sure that the gold triangle is on the top-left
corner of the socket then fit the socket alignment key into the CPU notch.
5. Pull back the load lever , then push the load
lever (A) until it snaps into the retention tab.

The CPU fits 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!
1.3.2 Installing the CPU Heatsink and Fan
Intel® Core™ i7/ i5/ i3 LGA1151 processor requires a specially designed heatsink and fan
assembly to ensure optimum thermal condition and performance.
Install the motherboard to the chassis before you install the CPU
fan and heatsink assembly.
When you buy a boxed Intel® Core™ i7/ i5/ i3 LGA1151
processor, the package includes the CPU fan and heatsink
assembly. If you buy a CPU separately, make sure that you use
only Intel® certified multi‑directional heatsink and fan.
Your Intel® Core™ i7/ i5/ i3 LGA1151 processor LGA1151
heatsink and fan assembly comes in a push-pin design and
requires no tool to install.
If you purchased a separate CPU heatsink and fan assembly, make
sure that you have properly applied Thermal Interface Material to the
CPU heatsink or CPU before you install the heatsink and fan
assembly. You also need to choose proper CPU heatsink and fan
based on different CPU TDP.
To install the CPU heatsink and fan:
1. Place the heatsink on top of the installed CPU, making sure that the four fasteners match
the holes on the motherboard.
Orient the heatsink and fan assembly such that the CPU fan cable is
closest to the CPU fan connector.

Make sure each fastener is oriented as shown, with the narrow
groove directed outward.
2. Push down two fasteners at a time in a
diagonal sequence to secure the heatsink and fan
assembly in place.
3. Connect the CPU fan cable to the connector on the motherboard labeled CPU_FAN.

Do not forget to connect the fan cables to the fan
connectors. Insufficient air flow inside the system may
damage the motherboard components. These are not
jumpers! DO NOT place jumper caps on the fan connectors.
