2.3 Installing Memory Modules (DIMM)

is motherboard provides four 288-pin DDR4 (Double Data Rate 4) DIMM slots,

and supports Dual Channel Memory Technology.

1. For dual channel conguration, you always need to install identica l (the same

brand, speed , size and chip-type) DDR4 DIMM pairs.

2. It is unable to activate Dual Channel Memor y Technology with only one or three
memor y module installed.

3. It is not allowed to install a DDR, DDR2 or DDR3 memory module into a DDR4
slot; otherwise, this motherboard and DIMM may be damaged.

e DIMM only ts in one correct orie ntation. It will cause permanent dam age to
the mothe rboard and the DIMM if you force the DIMM into the slot at incor rect

2.4 Expansion Slots (PCI Express Slots)

ere are 6 PCI Express slots on the motherboard.

Before installing an ex pansion card, please make sure that the power supply is
switched o or the power cord is unplugged. Plea se read the documentation of the
expan sion card and mak e necessary hardware settings for the card before you start
the installation.

PCIe slots:

PCIE1 (PCIe 3.0 x1 slot) is used for PCI Express x1 lane width cards.

PCIE2 (PCIe 3.0 x16 slot) is used for PCI Express x16 lane width graphics cards.

PCIE3 (PCIe 3.0 x1 slot) is used for PCI Express x1 lane width cards.

PCIE4 (PCIe 3.0 x16 slot) is used for PCI Express x8 lane width graphics cards.

PCIE5 (PCIe 3.0 x1 slot) is used for PCI Express x1 lane width cards.

PCIE6 (PCIe 3.0 x1 slot) is used for PCI Express x1 lane width cards.

2.5 Jumpers Setup

e illustration shows how jumpers are setup. When the jumper cap is placed on

the pins, the jumper is “Short”. If no jumper cap is placed on the pins, the jumper

is “Open”. e illustration shows a 3-pin jumper whose pin1 and pin2 are “Short”

when a jumper cap is placed on these 2 pins.

Clear CMOS Jumper

(CLRMOS1)

(see p.7 or 8, No. 20)

CLRMOS1 allows you to clear the data in CMOS. To clear and reset the system

parameters 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, time, and user default prole will be cleared only if the CMOS battery is

removed.
