SBC-372
Chapter 2 Installation
is is a 3.5”SBC (5.8-in x 4-in x 1.2-in, 14.7 cm x 10.2 cm x 2.95 cm) form factor mother-
board. Before you install the motherboard, study the conguration of your chassis to ensure
that the motherboard ts into it.
2.1 Screw Holes
Place screws into the holes to secure the motherboard to the chassis.
2.2 Pre-installation Precautions
Take note of the following precautions before you install motherboard components or change
any motherboard settings.
1. Unplug the power cord from the wall socket before touching any component.
2. To avoid damaging the motherboard components due to static electricity, NEVER place
your motherboard directly on the carpet or the like. Also remember to use a grounded
wrist strap or touch a safety grounded object before you handle components.
3. Hold components by the edges and do not touch the ICs.
4. Whenever you uninstall any component, place it on a grounded antistatic pad or in the
bag that comes with the component.
5. Heatsink (e thermal solution of whole system needs to be designed additionally.)
6. e Alder Lake-PS processor has integrated PCH, with a feature of PCH replacement
counter. e Intel ME supports a maximum PCH replacement for 20 times. Each time a
processor is replaced (even with the same model), the counter will add one to the count.
To reset the PCH replacement counter, please refer to https://www.asrockind.com/en-
gb/index.php?route=newsblog/faq&faq_id=88
Make sure to unplug the power cord before installing or removing the motherboard. Failure to
do so may cause physical injuries to you and damages to motherboard components.
Do not over-tighten the screws! Doing so may damage the motherboard.
Before you install or remove any component, ensure that the power is switched o 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.

10
2.3 Installation of Memory Modules (SO-DIMM)
SBC-372 provides one 262-pin DDR5 (Double Data Rate 5) SO-DIMM slot, and supports
Dual Channel Memory Technology.
Step 1. Align a SO-DIMM on the slot such that the notch on the SO-DIMM matches the
break on the slot.
Step 2. Firmly insert the SO-DIMM into the slot until the retaining clips at both ends fully
snap back in place and the SO-DIMM is properly seated.
1. e SO-DIMM only ts in one correct orientation. It will cause permanent damage to
the motherboard and the SO-DIMM if you force the SO-DIMM into the slot at incor-
rect orientation.
2. Please do not intermix dierent voltage SO-DIMMs on this motherboard.

SBC-372
2.4 Expansion Slots
ere are 2 M.2 sockets on this motherboard.
M.2 sockets:
1 x M.2 (Key E, 2230) with PCIe Gen3 x1 and USB 2.0 for Wireless
1 x M.2 (Key M, 2242/2260/2280) with PCIe Gen4 x4 for SSD

2.5 Jumpers Setup
The illustration shows how jumpers are setup.
When the jumper cap is placed on pins, the
jumper is “Short.” If no jumper cap is placed
on pins, the jumper is “Open.” The illustration
shows a 3-pin jumper whose pin1 and pin2 are
“Short” when jumper cap is placed on these 2
pins.
(3-pin CLRMOS1)
(see p. 4, No. 4)
NOTE: CLRMOS1 allows you to clear the data in CMOS. To clear and reset the system param-
eters to default setup, please turn o the computer and unplug the power cord from the power
supply. Aer waiting for 15 seconds, use a jumper cap to short pin2 and pin3 on CLRMOS1
for 5 seconds. However, please do not clear the CMOS right aer you update the BIOS. If you
need to clear the CMOS when you just nish updating the BIOS, you must boot up the system
rst, and then shut it down before you do the clear-CMOS action. Please be noted that the
password, date, and time will be cleared only if the CMOS battery is removed.
Clear CMOS Headers
(2-pin CLRMOS2)
(see p. 4, No. 2)
NOTE: CLRMOS2 allows you to clear the data in CMOS automatically when AC power on.
To clear and reset the system parameters to default setup, please turn o the computer and
unplug the power cord, then use a jumper cap to short the pins on CLRMOS2.
