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 unplug ged. Pl ease re ad the documentation of the expansion card and
make 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 x16 slot) is used for PCI Express x4 lane width graphics 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

(CLRMO S1)

(see p.8, No. 25)

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.

Onboard headers and connectors are NOT jump ers. Do NOT place jumper caps over these
heade rs and connectors. Placing jumper caps over the headers and connectors will cause
permanent damage to the motherboard.

PWRBTN (Power Switch):

Connec t to the power switch on the ch assi s front panel. You may congure the way to tur n

RESET (Reset Switch):
Connec t to the reset switch on the chassi s front panel. Press the reset sw itch to restart the
computer if the computer f reezes and fails to per form a normal restar t.

PLED (Syste m Power LED):
Connec t to the power status indicator on the chas sis front panel. e LED i s on when the
system is operating. e LED keeps blinking when the system is in S1/S3 sleep state. e
LED is o when the system is in S4 slee p state or powered o (S5).

HDLED (Ha rd Drive Activity LED):
Connec t to the hard drive ac tivity LED on the chassis front panel. e LED is on when the
hard drive is reading or wr iting data.

e front panel de sign may dier by chassis. A front panel module mainly consists of powe r
switch, reset switch , power LED, hard dr ive activity LED, speaker and etc. When connect­ing your ch assi s front panel module to thi s header, make sure the wire a ssignments and the
pin assignments are matched correctly.

Besides four USB 3.0 ports

on the I/O panel, there

are two headers on this

motherboard. Each USB

3.0 header can support

two ports.

is header is for

connecting audio devices

to the front audio panel.

1. High Denition Audio support s Jack Sensing, but the panel wire on the cha ssis must sup ­port HDA to function correctly. Ple ase fol low the instructions in our manual and chassis
manual to install your system.

2. If you use an AC’97 audio panel , please install it to th e front panel audio header by the
steps below:
A. Connect Mic_IN (MIC) to MIC2_ L.
B. Conne ct Audio_R (RIN) to OUT2_R and Audio_ L (LIN) to OUT2_ L.
C. Connect Ground (GND) to Ground (GND).
D. MIC_ RET and OUT_RET are for the HD audio panel only. You don’t ne ed to conn ect
them for the AC’97 audio panel .
E. To activate the front mic, go to the “FrontMic” Tab in the Realtek Control panel and
adjust “Recording Volume”.
