How to Install Asus WS C621E SAGE

• Step 1: Verify compatibility. Ensure you have Intel Xeon Scalable processors that fit LGA-3647 sockets and that your chassis supports the SSI EEB form factor. Update BIOS to the latest version prior to installation to maximize CPU and memory compatibility.

• Step 2: Prepare the chassis and cooling. Install the motherboard standoffs in the chassis, attach the CPU coolers or liquid cooling blocks, and confirm proper clearance for large GPUs and memory modules. Adequate airflow is essential for dual-CPU configurations and multi-GPU setups.

• Step 3: Install CPUs and memory. Place Xeon processors into their respective sockets with correct orientation, apply thermal paste if necessary, and secure cooling. Insert DDR4 DIMMs into the designated slots following the motherboard’s memory population guide to maximize bandwidth and stability across channels.

• Step 4: Mount expansion cards and storage. Install GPUs in appropriate PCIe slots, ensuring PCIe lane configuration aligns with your GPUs’ requirements. Attach NVMe drives to M.2 slots and/or U.2 connectors as needed, and configure any RAID or NVMe arrays in the BIOS or OS later.

• Step 5: Connect power and front-panel cables. Attach the main power connector and any CPU power connectors, plus the chassis power/reset buttons and LED indicators. Double-check all cables to prevent post-assembly issues and ensure stable power delivery to dual-CPU configurations.

• Step 6: Configure BIOS/UEFI. Enter the BIOS at first boot, set memory profiles (XMP or equivalent), enable any CPU multiplier or turbo settings allowed by your CPUs, and configure PCIe lane spacing for the GPUs. Save settings and reboot to confirm all components are detected correctly.

• Step 7: Install the operating system and drivers. Install your workstation OS, then add chipset, storage, GPU, and management drivers. Consider enabling ASUS management features or enterprise utilities that help monitor power, temperature, and system health remotely.

• Step 8: Run validation tests. After installation, run stress tests and benchmarks specific to your workloads to verify stability, cooling performance, and platform responsiveness under load. Fine-tune BIOS settings if necessary for peak performance without compromising reliability.
