Setup and Installation

Motherboard Components Overview

Familiarize yourself with the various components and ports on the motherboard before installation.

Memory Installation

The motherboard supports DDR4 memory. Follow these steps for proper installation:

1. Align the notch on the memory module with the key in the DIMM slot.
2. Press down firmly on both ends of the memory module until the clips on the slot snap into place.
3. If using a single memory stick, install it in the outermost black memory slot near the SATA port.
4. If using two memory sticks, install them both in the black memory slots to ensure dual-channel operation. Failure to do so may prevent the system from booting.

Storage Device Installation (M.2 Slots)

The motherboard features two NVMe M.2 slots for high-speed storage:

• The upper M.2 slot supports PCIe 3.0 x4 (NVMe only) with speeds up to 3700MB/s.
• The bottom M.2 slot supports PCIe 2.0 x2 (NVMe only) with speeds up to 831MB/s.
• A dedicated M.2 WiFi slot supports PCIe (NGFF) protocol wireless network cards. CNVI protocol is not supported.

Maintenance

Clearing CMOS

Clearing the CMOS can resolve certain boot or configuration issues. There are two methods:

Method 1: Using the Recovery Jumper

1. Power off the computer and disconnect all power cables.
2. Remove all installed components (CPU, RAM, GPU, etc.).
3. Locate the 2-pin Clear CMOS header (labeled CLR_CMOS or similar) on the motherboard.
4. Use a metal conductive object (like tweezers) to short the two pins for 3-5 seconds.

Method 2: Removing the Battery

1. Power off the computer and disconnect all power cables.
2. Locate the small circular CMOS battery (CR2032) on the motherboard.
3. Carefully remove the battery from its holder.
4. Wait for 1-5 minutes to ensure the CMOS memory is fully discharged.
5. Reinstall the battery and reconnect all power cables and devices.
