The board includes a dedicated IPMI 2.0 LAN port. By default, use the IPMI utility to find its IP address, then access the web interface using a browser. Default credentials are often ADMIN/ADMIN; change them immediately for security.
What is the maximum memory capacity?
The maximum memory capacity is 4 TB when using 256 GB LRDIMMs. For most configurations, 16 slots allow flexible capacity and memory interleaving to enhance performance.
Does it support NVMe drives?
Yes, the motherboard supports NVMe PCIe 4.0 storage via its PCIe slots. It also has standard SATA 3.0 ports for traditional drives. For direct NVMe boot, ensure the BIOS and UEFI settings are configured accordingly.
What is the recommended power supply wattage?
For two high-end Xeon Scalable CPUs, a 1200-watt or higher power supply with dual EPS 8-pin connectors is recommended. Choose a unit with 80 PLUS Gold or better efficiency and sufficient +12V capacity.
How do I update the BIOS?
Download the latest BIOS from Supermicro's website, extract to a FAT32 USB drive, and use the IPMI BMC or the bootable DOS utility included in the package. Ensure a stable power supply during the update.
