4.2. Installing the CPU
- Locate the AM4 CPU socket on the motherboard.
- Lift the load lever on the side of the socket.
- Carefully align the triangular mark on the CPU with the mark on the socket.
- Gently place the CPU into the socket without forcing it.
- Lower the load lever to secure the CPU in place.
4.3. Installing Memory (RAM)
- Open the clips on both ends of the DIMM slots.
- Align the notch on the DDR4 memory module with the key in the DIMM slot.
- Insert the memory module firmly into the slot until the clips snap into place. For optimal performance, install memory modules in matching pairs into the designated dual-channel slots (refer to the motherboard's silkscreen or full manual for specific slot recommendations).
4.4. Installing M.2 SSDs
This motherboard features two M.2 slots. The top slot (nearest the CPU) supports PCIe 4.0, while the second slot supports PCIe 3.0.
- Locate the M.2 slots and remove the thermal guard/heatsink if present.
- Insert the M.2 SSD into the slot at a 30-degree angle.
- Gently push the SSD down and secure it with the provided M.2 screw.
- Reinstall the thermal guard/heatsink, ensuring proper contact with the SSD.
4.5. Connecting Power Supply
- Connect the 24-pin ATX main power connector from your power supply to the motherboard.
- Connect the 8-pin (or 4+4 pin) ATX 12V CPU power connector to the motherboard.
4.6. Installing Expansion Cards (e.g., Graphics Card)
- Align your graphics card or other PCIe expansion card with the PCIe x16 slot (the top reinforced slot for graphics cards).
- Press down firmly until the card is seated correctly and the retention clip at the end of the slot locks into place.
- Secure the card to your PC case with a screw.
4.7. Connecting Front Panel Cables and Peripherals
- Connect your case's front panel connectors (Power LED, HDD LED, Power Switch, Reset Switch) to the corresponding pins on the motherboard's front panel header. Refer to the motherboard's silkscreen for correct pin alignment.
- Connect USB 2.0, USB 3.0, and USB 3.2 Gen1 Type-C front panel headers if your case supports them.
- Connect the front panel audio cable.
- Connect SATA data cables to your storage drives (HDDs/SSDs) and the motherboard's SATA ports.
- Attach the Wi-Fi antenna to the rear I/O panel.
