3. Installation Guide
3.1 CPU Cooler Installation
- The AMD Ryzen processor is integrated onto the motherboard.
- Apply thermal paste to the CPU's integrated heat spreader (IHS).
- Install the CPU cooler (compatible with LGA1700 mounting) onto the motherboard, securing it with the provided hardware. Refer to the cooler's manual for specific instructions.
3.2 Memory (RAM) Installation
- Locate the two SO-DIMM DDR5 memory slots.
- Open the clips at both ends of the memory slot.
- Align the notch on the DDR5 SO-DIMM module with the key in the memory slot.
- Insert the memory module firmly into the slot until the clips snap into place.
- Ensure both clips are fully closed and the module is seated evenly.
3.3 Storage Device Installation
M.2 NVMe SSD Installation:
- Locate the two M.2 NVMe PCIe 4.0 x2 slots (2280 size).
- Remove the M.2 standoff screw from the motherboard.
- Insert the M.2 SSD into the slot at a 30-degree angle.
- Gently push down the SSD and secure it with the standoff screw.
SATA Drive Installation:
- Connect SATA data cables from your SATA drives to the SFF-8643 sockets on the motherboard. Note that SFF-8643 requires a breakout cable (one to four SATA3.0) for connecting multiple drives.
- Connect SATA power cables from your power supply to the SATA drives.
- The motherboard also features a dedicated SATA3.0 socket and a SATA4PIN power socket for additional connectivity.
3.4 Power Supply Connection
- Connect the 24-pin ATX power connector from your power supply to the 24-pin ATX socket on the motherboard.
- Connect the 8-pin (or 4-pin) CPU power connector from your power supply to the 8-pin CPU power socket on the motherboard. A 500W or more power supply is recommended, especially when using 9 disks.
3.5 Peripheral Connections
- Display: Connect your monitor to the HDMI2.0, DP1.4, or Type-C (USB4) ports on the I/O panel.
- Network: Connect Ethernet cables to the four Intel 2.5G RJ45 ports.
- USB Devices: Connect USB devices to the USB3.2 and Type-C (USB4) ports on the I/O panel. Utilize the internal USB2.0 and USB3.2 pin headers for front panel USB ports.
- Audio: Connect audio devices to the 2-in-1 audio interface.
- Front Panel Connectors: Connect your chassis's front panel cables (power button, reset button, HDD LED, power LED) to the F_PANEL header.
- Fans: Connect system fans and the CPU fan to the designated 4-pin fan power supply pins.
