Chapter 2 Installation

is is an ATX form factor motherboard. Before you install the motherboard, study the conguration 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

•

components. Failure to do so may cause physical injuries 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 1700-Pin CPU into the socket, please check if the P nP cap is on the socket, if the CPU sur face is unclean, or if there are any b ent pins in the socket. Do not force to insert the CPU into the socket if above situation is found. Other wise, the CPU will be seriously d amaged.

2. Unplug all power cables be fore installing the CPU.

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 identical (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 memory 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.

2.4 Expansion Slots (PCIe Slots)

ere are 4 PCIe 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 make necessary hardware settings for the card before you start the installation.

PCIe slots: PCIE1 (PCIe 4.0 x16 slot) is used for PCIe x16 lane width graphics cards. PCIE2 (PCIe 3.0 x1 slot) is used for PCIe x1 lane width cards. PCIE3 (PCIe 3.0 x16 slot) is used for PCIe x4 lane width graphics cards.

PCIE4 (PCIe 3.0 x1 slot) is used for PCIe 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”.

Clear CMOS Jumper (CLRMOS1) (see p.1, No. 22)

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 the pins 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. Please remember toremove the jumper cap aer clearing the CMOS.

2-pin Jumper

B660 Pro RS

If you clear the CMOS, the case open may be detec ted. Please adjust the BIOS option “Clear Status” to clear the record of previou s chassis intrusion status.

2.6 Onboard Headers and Connectors

SPE AKE R

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 (9-pin PANEL1) (see p.1, No. 18)

PWRBTN (Power Button):

Connec t to the power button on the chassi s front panel. You may congure the way to turn o your system using the powe r button.

RESET (Reset Button):

Connec t to the reset button on the chassi s front panel. Press the reset button to restar t the computer if the computer freezes and fails to perform a nor mal restart.

PLED (Syste m Power LED):

Connec t to the power status indicator on the chassis front panel. e LED i s on when the system is ope rating. e LED keeps blinking when the system i s in S1/S3 sleep state. e LED is o when the system is in S4 sleep state or powered o (S5).

HDLED (Ha rd Drive Activity LED):

Connec t to the hard drive activity LED on the chassis front panel. e LED is on when the hard drive i s reading or writing data.

e front panel design may dier by chassis. A front panel module mainly consists of power button, reset button, power LED, hard drive activity LED, speaker and etc. When connecting your chassis front panel module to this head er, make sure the wire assig nments and the pin assig nments are matched correctly.

2.7 Smart Button

e motherboard has a smart button: BIOS Flashback Button, allowing users to ash the BIOS.

B660 Pro RS

BIOS Flashback Button (BIOS_FB1)

BIOS Flashback Switch allows users to ash the BIOS.

(see p.3, No. 10)

ASRock BIOS Flashback feature allows you to update BIOS without powering on the system, even without CPU.

Before u sing the BIOS Flashback f unction, please su spend BitLocker and any encryption or security relying on the TPM. Make sure that you have already stored and backup -ed the recovery key. If the recovery key is missing while encryption is active, the data w ill stay encrypted and the system will not boot into the operating system. It is recommended to disable fTPM before updating the BIOS. Otherwise an unpredictable failure may occur.

To use the USB BIOS Flashback function, Please follow the steps below.

1. Download the latest BIOS le from ASRock's website : http://www.asrock.com.

2. Copy the BIOS le to your USB ash drive. Please make sure the le system of

your USB ash drive must be FAT32.

3. Extract BIOS  le from the zip le.

4. Rename the le to “creative.rom” and save it to the root directory of X: USB ash drive.

5. Plug the 24 pin power connector to t he motherboard. en turn on the power supply's AC switch. *ere is no need to power on the system.

6. en plug your USB drive to the USB BIOS Flashback port.

7. Press the BIOS Flashback Switch for about three seconds. en the LED starts to blink.

8. Wait until the LED stops blinking, indicating that BIOS ashing has been completed. *If the LED light turns solid green, this means that the BIOS Flashback is not operating properly. Please make sure that you plug the USB drive to the USB BIOS Flashback port. **If the LED does not light up at all then please disconnect power from the system and remove/ disconnect the CMOS battery from the motherboard for several minutes. Reconnect power and battery and try again.

2.9 M.2 WiFi/BT PCIe WiFi Module and Intel® CNVi (Integrated WiFi/BT) Installation Guide

e M.2, also known as the Next Generation Form Factor (NGFF), is a small size and versatile card edge connector that aims to replace mPCIe and mSATA. e M.2 Socket (Key E) supports type 2230 WiFi/BT PCIe WiFi module and Intel® CNVi (Integrated WiFi/BT). * e M.2 socket does not support SATA M.2 SSDs.

Before you install Intel® Integrated Connectivity (CNVi) module, be sure to turn o the AC power.

Installing the WiFi/BT module or Intel® CNVi (Integrated WiFi/BT)

Step 1

Prepare a type 2230 WiFi/BT PCIe WiFi module or Intel® CNVi (Integrated WiFi/BT) and the screw.

PCB Length: 3cm Module Type: Type2230

Step 2

Find the nut location to be used.

English

Step 3

Gently insert the WiFi/BT module or Intel® CNVi (Integrated WiFi/ BT) into the M.2 slot. Please be aware that the module only ts in one orientation.

Step 4

Tighten the screw with a screwdriver to secure the module into place. Please do not overtighten the screw as this might damage the module.
