Motherboard information

2.1Before you proceed

Take note of the following precautions before you install motherboard components or change any motherboard settings.

CAUTION!

•Unplug the power cord from the wall socket before touching any component.

•Before handling components, use a grounded wrist strap or touch a safely grounded object or a metal object, such as the power supply case, to avoid damaging them due to static electricity.

•Hold components by the edges to avoid touching the ICs on them.

•Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that came with the component.

•Before you install or remove any component, always remove the AC power by unplugging the power cord from the power outlet. Failure to do so may cause severe damage to the motherboard, peripherals, or components.

Chapter 2: Motherboard information

2.2Motherboard layout

NOTE: Place eight screws into the holes indicated by circles to secure the motherboard to the chassis.

CAUTION! Do not overtighten the screws! Doing so can damage the motherboard.

Place this side towards the rear of the chassis

2.3Central Processing Unit (CPU)

The motherboard comes with a surface mount LGA1151 socket designed for the Intel® 9th/8th Generation Core™ i9 / i7 / i5 / i3, Pentium®, and Celeron® processors.

LGA1151

IMPORTANT: Unplug all power cables before installing the CPU.

CAUTION!

•Upon purchase of the motherboard, ensure that the PnP cap is on the socket and the socket contacts are not bent. Contact your retailer immediately if the PnP cap is missing, or if you see any damage to the

PnP cap/socket contacts/motherboard components. The manufacturer will shoulder the cost of repair only if the damage is shipment/transit-related.

•Keep the cap after installing the motherboard. The manufacturer will process Return Merchandise Authorization (RMA) requests only if the motherboard comes with the cap on the LGA1151 socket.

•The product warranty does not cover damage to the socket contacts resulting from incorrect CPU installation/removal, or misplacement/loss/ incorrect removal of the PnP cap.

1.Clear RTC RAM (2-pin CLRTC)

This header allows you to clear the CMOS RTC RAM data of the system setup information such as date, time, and system passwords.

CLRTC

<![if ! IE]>

<![endif]>+3V_BAT GND

PIN 1

Connector type HEADER 1x2p, 2.54mm pitch, S/T

To erase the RTC RAM:

1.Turn OFF the computer and unplug the power cord.

2.Use a metal object such as a screwdriver to short the two pins.

3.Plug the power cord and turn ON the computer.

4.Hold down the <Del> key during the boot process and enter BIOS setup to re-enter data.

NOTE: If the steps above do not help, remove the onboard battery and move the jumper again to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the battery.

2.Chassis intrusion header (4-1 pin_CHASSIS)

This header is for a chassis-mounted intrusion detection sensor or switch. Connect one end of the chassis intrusion sensor or switch cable to this connector. The chassis intrusion sensor or switch sends a low-level signal to this connector

when a chassis component is installed. The signal is then generated as a chassis intrusion event.
