How to install ASRock Rack X399D8A-2T

• Preparation: Power down your system, unplug the power cord, and discharge any static electricity. Gather a compatible Ryzen Threadripper CPU, an appropriate cooler, memory modules, SATA cables, a suitable power supply, and a chassis that accommodates an ATX motherboard. Verify compatibility with your chassis and ensure you have all necessary mounting hardware and anti-static precautions in place.
• CPU installation: Open the CPU socket retention mechanism for Socket TR4. Align the Ryzen Threadripper processor with the socket notches, then carefully insert it into place. Lower the retention lever and secure the socket according to the motherboard manual. Apply a thin, even layer of thermal paste on the CPU if your cooler requires it, then attach the CPU cooler and connect the fan header to the appropriate CPU fan header.
• Memory installation: Install memory modules in the recommended DIMM slots to enable quad-channel operation. Start from the first pair of slots and populate all eight slots to reach the maximum memory capacity. Ensure each DIMM clicks securely into position and that the latches lock on both ends. If you’re using memory kits, follow the manufacturer’s guidelines for populated slot order to achieve optimal performance and stability.
• Storage configuration: Connect your SATA drives using the eight SATA ports. Plan your storage topology in advance—decide which drives will be used for boot, which will be part of a RAID array, and which will be data drives. If you plan to use RAID, configure the array in BIOS or install the appropriate RAID controller as needed. Ensure cables are routed neatly to avoid interference with fans and other components.
• Chassis installation and power:Mount the motherboard into the chassis using the included stand-offs. Connect the main power connector and the CPU 8-pin power connector, along with any required PCIe power cables for expansion cards. Tie down cables to maintain airflow and access to components. Before powering up, double-check all connections, including case switches and front-panel headers, to ensure proper operation when you boot for the first time.
• BIOS configuration: Power on and enter the BIOS/UEFI. Enable or adjust memory XMP profiles to match your RAM’s rated speed, set boot order, and configure virtualization features if required for your workload (e.g., VT-d/AMD-V). If you plan to use a RAID configuration, ensure the SATA mode is set appropriately (AHCI or RAID) and install any required drivers as part of your OS installation.
• Operating system and drivers: Begin with your chosen server OS installation. After installation, install chipset, storage, and any motherboard drivers from ASRock Rack’s support resources. Update the BIOS if a newer version is available to ensure compatibility, stability, and security patches. Finally, configure network settings, storage pools, and any virtualization or container platforms you plan to deploy on the server.
