- Align the motherboard with the standoffs and gently lower it into place.
- Secure the motherboard with screws, ensuring not to overtighten.
4.2. CPU Installation (Xeon E5 2650 V4)
- Locate the LGA 2011-3 CPU socket on the motherboard.
- Open the CPU socket retention mechanism by pushing down and out on the lever(s).
- Carefully align the Xeon E5 2650 V4 CPU with the socket, matching the golden triangle/arrow on the CPU with the corresponding mark on the socket. Do not force the CPU into the socket.
- Gently lower the CPU into the socket.
- Close the retention mechanism by pushing the lever(s) back into place until they click.
- Apply a thin, even layer of thermal paste to the top of the CPU.
- Install your CPU cooler according to its manufacturer's instructions, ensuring proper contact and secure mounting.
4.3. RAM Installation (DDR4 ECC)
- Locate the 4 DDR4 memory slots. For dual-channel operation, refer to your motherboard's specific manual for recommended slot pairing (e.g., A1 and B1).
- Open the clips at both ends of the memory slot.
- Align the notch on the DDR4 memory module with the key in the memory slot.
- Press down firmly on both ends of the memory module until the clips snap into place.
4.4. Storage Device Installation (M.2 NVMe/SATA & SATA)
4.4.1. M.2 SSD Installation
- Locate the M.2 slots on the motherboard.
- Remove the M.2 standoff screw from the desired slot.
- Insert the M.2 SSD into the slot at a 30-degree angle, ensuring the gold contacts are fully seated.
- Gently push down the M.2 SSD and secure it with the standoff screw.
4.4.2. SATA Drive Installation
- Connect one end of a SATA data cable to a SATA port on the motherboard.
- Connect the other end of the SATA data cable to your SATA hard drive or SSD.
- Connect a SATA power cable from your power supply to the SATA hard drive or SSD.
4.5. Graphics Card Installation (PCIe x16)
- Locate the PCIe x16 slot.
- Remove the corresponding expansion slot cover from your PC case.
- Open the retention clip at the end of the PCIe x16 slot.
- Align your graphics card with the slot and press down firmly until it is fully seated and the retention clip snaps into place.
- Secure the graphics card to the case with a screw.
- Connect any necessary PCIe power cables from your power supply to the graphics card.
4.6. Power Connections
- Connect the 24-pin ATX main power connector from your power supply to the motherboard.
- Connect the 8-pin +12V CPU power connector (or 4-pin if applicable) from your power supply to the motherboard.
