How to Install Supermicro X11DAC Workstation Motherboard

• Prepare a compatible Extended ATX chassis with adequate airflow and a high-quality power supply. Confirm that the chassis supports the DP configuration you intend to use (single or dual Xeon processors) and that there is space for expansion cards and storage devices.
• Install the CPU(s) into the LGA-3647 socket(s). Follow the processor orientation marks, apply thermal paste as required, and secure the heatsinks with the correct mounting hardware to ensure proper cooling and CPU stability.
• Install memory DIMMs in the recommended slots for optimal memory channel performance. Use ECC DDR4 modules to take advantage of error correction and system reliability. Route memory cables and verify that all DIMMs are fully seated.
• Mount the motherboard into the chassis using the appropriate standoffs. Connect the 24-pin main power, the CPU power connectors, and any additional power rails required by your DP configuration. Attach the motherboard power cables securely to prevent startup issues.
• Install storage devices (NVMe and SATA) and any PCIe expansion cards. Connect data and power cables as needed, ensuring no cables obstruct fans or airflow. Install an operating system or boot device and configure the BIOS/UEFI settings for your workload, including memory profiles, CPU options, and boot order.
