Frequently Asked Questions - J4125M ASROCK

Which processors are compatible with the ASROCK J4125M motherboard?

The ASROCK J4125M motherboard is equipped with an integrated (soldered) Intel Quad-Core J4125 processor. Only this processor is compatible with this model. The J4025M version integrates an Intel Dual-Core J4025 processor.

What is the maximum RAM memory capacity supported?

The maximum supported memory is 8 GB in dual-channel DDR4 configuration, with unbuffered non-ECC modules. 2 GB modules are not supported.

Does the motherboard support discrete graphics?

Yes, it has a PCI Express 2.0 x16 slot (operating in x1 mode) for a discrete graphics card. However, performance will be limited due to the x1 bandwidth.

How to clear the CMOS on this motherboard?

To clear the CMOS, turn off the computer and unplug the power cord. Wait 15 seconds, then short pins 2 and 3 of the CLRMOS1 jumper for 5 seconds. Replace the cap and reconnect power.

What video output ports are available?

The video output ports are a D-Sub, a DVI-D, and an HDMI 2.0. The motherboard supports up to three simultaneous monitors.

Can I install an M.2 NVMe drive?

No, the M.2 (Key E) slot is intended only for an Intel CNVi Wi-Fi/BT module. It does not support NVMe or SATA M.2 drives.

What BIOS software is used?

The BIOS is an UEFI AMI with GUI, supporting PnP, ACPI 5.0, and SMBIOS 3.0.

Does the motherboard support Windows 11?

Officially, it supports only Windows 10 64-bit. Windows 11 is not certified, but may work if the TPM 2.0 and Secure Boot prerequisites are met (the UEFI BIOS allows this).

How to connect the front panel of the case?

Connect the front panel cables to the PANEL1 header (9 pins). Observe polarity: PWRBTN for power, RESET for reset, PLED for power LED, and HDLED for hard drive activity.

What precautions should be taken when cleaning?

Use a soft dry cloth or compressed air. Avoid liquids and chemicals. Unplug the power before cleaning. Do not touch the printed circuit boards with your fingers.

Chapter 2 Installation

This is a Micro ATX form factor motherboard. Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits 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 overtighten the screws! Doing so may damage the motherboard.

2.1 Installing Memory Modules (DIMM)

This motherboard provides two 288-pin DDR4 (Double Data Rate 4) DIMM slots, and supports Dual Channel Memory Technology.

1. 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. The DIMM only fits 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.

Supported DDR4 Non ECC DIMM

2.2 Expansion Slots (PCI Express Slots)

There are 3 PCI Express slots on the motherboard.

Before installing an expansion card, please make sure that the power supply is switched off 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.

PCIe slot:

PCIE1 (PCIe 2.0 x1 slot) is used for PCI Express x1 lane width cards.
PCIE2 (PCIe 2.0 x16 slot) is used for PCI Express x1 lane width cards.
PCIE3 (PCIe 2.0 x1 slot) is used for PCI Express x1 lane width cards.

Warning:

To ensure better graphics compatibility, the BIOS is set to "boot from Onboard VGA" as default even the user install a VGA card on PCIe slot.

2.3 Jumpers Setup

The 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". The 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.1, No. 1)

Clear CMOSDefault

CLRMOS1 allows you to clear the data in CMOS. To clear and reset the system parameters to default setup, please turn off the computer and unplug the power cord from the power supply. After 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 after you update the BIOS. If you need to clear the CMOS when you just finish updating the BIOS, you must boot up the system first, and then shut it down before you do the clear-CMOS action. Please be noted that the password, date, time, and user default profile 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.

2.4 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 (9-pin PANEL1) (see p.1, No. 8)

Connect the power switch, reset switch and 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 configure the way to turn off 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. The LED is on when the system is operating. The LED keeps blinking when the system is in S1/S3 sleep state. The LED is off when the system is in S4 sleep state or powered off (S5).

HDLED (Hard Drive Activity LED):

Connect to the hard drive activity LED on the chassis front panel. The LED is on when the hard drive is reading or writing data.

The front panel design may differ 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.

Chassis Intrusion and
Speaker Header
(7-pin SPK_CI1)
(see p.1, No. 10)

Please connect the chassis intrusion and the chassis speaker to this header.

Serial ATA3 Connectors

(SATA3_1:

(SATA3_2:

see p.1, No. 6)

SATA3_1

SATA3_2

These two SATA3

connectors support SATA

data cables for internal

storage devices with up to
