Chapter 2 Installation: ASRock b85m pro4
Chapter 2 Installation
is is a Micro ATX form factor motherboard. Before you install the motherboard,
study the conguration of your chassis to ensure that the motherboard ts into it.
Pre-installation Precautions
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
•
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.
•
In order to avoid damage from static electricity to the motherboard’s components,
NEVER place your motherboard directly on a carpet. Also remember to use a grounded
wrist strap or touch a safety grounded object before you handle the components.
•
Hold components by the edges and do not touch the ICs.
•
Whenever you uninstall any components, place them on a grounded anti-static pad or
in the bag that comes with the components.
•
When placing screws to secure the motherboard to the chassis, please do not over-
tighten the screws! Doing so may damage the motherboard.

2.1 Installing the CPU
1. Before you insert the 1150-Pin CPU into the socket, please check if the PnP cap is on
the socket, if the CPU surface is unclean, or if there are any bent pins in the socket.
Do not force to insert the CPU into the socket if above situation is found. Otherwise,
the CPU will be seriously damaged.
2. Unplug all power cables before installing the CPU.

2.3 Installing Memory Modules (DIMM)
is motherboard provides four 240-pin DDR3 (Double Data Rate 3) DIMM slots,
and supports Dual Channel Memory Technology.
1. For dual channel conguration, you always need to install identical (the same
brand, speed, size and chip-type) DDR3 DIMM pairs.
2. It is unable to activate Dual Channel Memory Technology with only one or three
memory module installed.
3. It is not allowed to install a DDR or DDR2 memory module into a DDR3 slot;
otherwise, this motherboard and DIMM may be damaged.

e DIMM only ts in one correct orientation. It will cause permanent damage to
the motherboard and the DIMM if you force the DIMM into the slot at incorrect
orientation.

2.4 Expansion Slots (PCI and PCI Express Slots)
ere are 2 PCI slots and 2 PCI Express slots on the motherboard.
Before installing an expansion card, please make sure that the power supply is
switched o or the power cord is unplugged. Please read the documentation of the
expansion card and make necessary hardware settings for the card before you start
the installation.
PCI slot:
e PCI1 and PCI2 slots are used to install expansion cards that have 32-bit PCI
interface.
PCIe slots:
PCIE1 (PCIe 3.0 x16 slot) is used for PCI Express x16 lane width graphics cards.
PCIE2 (PCIe 2.0 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
(CLRCMOS1)
Clear CMOSDefault
(see p.10, No. 22)
CLRCMOS1 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. Aer waiting for 15 seconds, use a jumper cap to
short pin2 and pin3 on CLRCMOS1 for 5 seconds. However, please do not clear
the CMOS right aer 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 prole will be cleared only if the CMOS battery is
removed.
If you clear the CMOS, the case open may be detected. Please adjust the BIOS option
“Clear Status” to clear the record of previous chassis intrusion status.

2.6 Onboard Headers and Connectors
Onboard headers and connectors are NOT jumpers. Do NOT place jumper caps over
these headers and connectors. Placing jumper caps over the headers and connectors
will cause permanent damage to the motherboard.
System Panel Header
Connect the power
(9-pin PANEL1)
switch, reset switch and
(see p.10, No. 12)
system status indicator on
the chassis to this header
according to the pin
assignments below. Note
the positive and negative
pins before connecting
the cables.
PWRBTN (Power Switch):
Connect to the power switch on the chassis front panel. You may congure the way to
turn o your system using the power switch.
RESET (Reset Switch):
Connect to the reset switch on the chassis front panel. Press the reset switch to restart
the computer if the computer freezes and fails to perform a normal restart.
PLED (System Power LED):
Connect to the power status indicator on the chassis front panel. e LED is 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 sleep state or powered o (S5).
HDLED (Hard Drive Activity LED):
Connect to the hard drive activity LED on the chassis front panel. e LED is on when
the hard drive is reading or writing data.
e front panel design may dier by chassis. A front panel module mainly consists
of power switch, reset switch, power LED, hard drive activity LED, speaker and etc.
When connecting your chassis front panel module to this header, make sure the wire
assignments and the pin assignments are matched correctly.
