Installing the Motherboard
2-1. Safety Precautions
2-2. Installing the motherboard in a Chassis
This motherboard carries a Micro ATX form factor of 225 x 185 mm. Choose a chassis
that accommodates this from factor. Make sure that the I/O template in the chassis
matches the I/O ports installed on the rear edge of the motherboard. Most system
chassis have mounting brackets installed in the chassis, which corresponds to the
holes in the motherboard. Place the motherboard over the mounting brackets and
secure the motherboard onto the mounting brackets with screws.
Follow these safety precautions when installing the motherboard:
• Wear a grounding strap attached to a grounded device to avoid damage
from static electricity.
• Discharge static electricity by touching the metal case of a safely grounded
object before working on the motherboard.
• Leave components in the static-proof bags.
• Always remove the AC power by unplugging the power cord from the power
outlet before installing or removing the motherboard or other hardware
components.
Do not over-tighten the screws as this can stress the motherboard.

The following illustration shows the location of the motherboard jumpers. Pin 1 is
labeled.
To avoid the system instability after clearing CMOS, we recommend users to
enter the main BIOS setting page to “Load Default Settings” and then “Save
and Exit Setup”.

2-4. Installing Hardware
2-4-1. Installing the Processor
• This motherboard has an LGA1151 socket.
• When choosing a processor, consider the performance requirements of
the system. Performance is based on the processor design, the clock speed
and system bus frequency of the processor, and the quantity of internal
cache memory and external cache memory.
• You may be able to change the settings in the system Setup Utility. We
strongly recommend you do not over-clock processor or other
components to run faster than their rated speed.
• The following illustration shows CPU installation components.
A. Press the hook of lever down with your thumb and pull it to the right
side to release it from retention tab.
B. Lift the tail of the load lever and rotate the load plate to fully open
position.
C. Grasp the edge of the package substrate. Make sure pin 1 indicator
is on your bottom-left side. Aim at the socket and place the package
carefully into the socket by purely vertical motion.

B250H4-M20 USER MANUAL
D. Rotate the load plate onto the package IHS (Intergraded Heat
Spreader). Engage the load lever while pressing down lightly onto the
load plate. Secure the load lever with the hook under retention tab. Then
the cover will flick automatically.
Please save and replace the cover onto the CPU socket if processor is re-
moved.

11
B250H4-M20 USER MANUAL
A. Apply some thermal grease onto the contacted area between the
heatsink and the CPU, and make it to be a thin layer.
B. Fasten the cooling fan supporting base onto the CPU socket on the
motherboard. And make sure the CPU fan is plugged to the CPU fan
connector.
C. Connect the CPU cooler power connector to the CPU_FAN connector.
2-4-2. Installing the CPU Cooler
• Install the cooling fan in a well-lit work area so that you can clearly see the
motherboard and processor socket.
• Avoid using cooling fans with sharp edges in case the fan casing and the
clips cause serious damage to the motherboard or its components.
• To achieve better airflow rates and heat dissipation, we suggest that you
use a high quality fan with 3800 rpm at least. CPU fan and heat sink instal-
lation procedures may vary with the type of CPU fan/heatsink supplied.
The form and size of fan/heatsink may also vary.
• DO NOT remove the CPU cap from the socket before installing a CPU.
• Return Material Authorization (RMA) requests will be accepted only if the
motherboard comes with the cap on the LGA1151 socket.
• The following illustration shows how to install CPU fan.

12
B250H4-M20 USER MANUAL
2-4-3. Installing Memory Modules
• This motherboard accommodates two memory modules. It can support
two 288-pin DDR4 2400/2133 MHz.
• Do not remove any memory module from its antistatic packaging until
you are ready to install it on the motherboard. Handle the modules only
by their edges. Do not touch the components or metal parts. Always wear
a grounding strap when you handle the modules.
• You must install at least one module in any of the two slots. Total memory
capacity is 32 GB.
• Refer to the following to install the memory modules.
We suggest users not to mix memory type. It is recommended to use the
same brand and type memory on this motherboard.
C. The slot latche is levered upwards and latch on to the edges of the
DIMM.
A. Push the latche on the mobilizable side of the DIMM slot down.
B. Install the DIMM module into the slot and press it firmly down until it
seats correctly. Check that the cutouts on the DIMM module edge
connector match the notches in the DIMM slot.

2-4-4. Installing Add-on Cards
The slots on this motherboard are designed to hold expansion cards and connect
them to the system bus. Expansion slots are a means of adding or enhancing the
motherboard’s features and capabilities. With these efficient facilities, you can
increase the motherboard’s capabilities by adding hardware that performs tasks
that are not part of the basic system.
Before installing an add-on card, check the documentation for
the card carefully. If the card is not Plug and Play, you may have
to manually configure the card before installation.
The PCI Express x1 slot is fully compliant to the PCI Express Base
Specification revision 3.0.
PCIEX1_1 Slot
PCIEX16 Slot The PCI Express x16 slots is used to install an external PCI
Express graphics card that is fully compliant to the PCI Express
Base Specification revision 3.0.
This is M.2 slot, 2242/2260/2280 supports PCI-E Gen3 x 4 SSD &
Intel®OptaneTM Technology.

1 Remove a blanking plate from the system case corresponding to the slot
you are going to use.
2 Install the edge connector of the add-on card into the expansion slot.
Ensure that the edge connector is correctly seated in the slot.
3 Secure the metal bracket of the card to the system case with a screw.
Follow these instructions to install an add-on card:
For some add-on cards, for example graphics adapters and network adapt-
ers, you have to install drivers and software before you can begin using the
add-on card.
Please refer the following illustrations to install the add-on card:
Install the VGA Card in the PCIEX16 slot
Install the LAN Card in the PCIEX1 slot
