Dual EPYC Server Board

The Supermicro MBD-H12DSI-NT6-B is an Extended ATX server motherboard built for dual AMD EPYC 7002 and 7003 series processors in Socket SP3. It targets high-density compute nodes, virtualisation clusters and storage appliances that need maximum core count per chassis. Builders requiring single-socket operation or consumer-grade features should look elsewhere.

Memory and Expansion Limits

Sixteen DDR4 DIMM slots support up to 4TB of registered ECC memory at 3200MHz, filling every channel across both sockets. Six PCI-E 4.0 expansion slots provide three x16 and three x8 links for accelerators, networking or storage controllers. A single M.2 M-key slot accepts 2280 or 22110 form factors at PCI-E 4.0 x4 speeds.

BIOS Gate for Newer CPUs

The board ships with BIOS that must be at version 2.3 or newer before an AMD EPYC 7003 series processor with 3D V-Cache technology will post. Without that update the system will not boot, so plan firmware preparation before installing those specific SKUs.

Spørgsmål om denne vare

Should I choose the EPYC 7002 or 7003 series for this Socket SP3 board?

Both series fit the same Socket SP3, but the 7003 series needs BIOS 2.3 or newer to enable 3D V-Cache technology.

What does the 3200 MHz DDR4 rating mean once the board is populated with 16 DIMMs?

The board supports up to 4 TB of registered ECC DDR4 at 3200 MHz across all 16 slots when compatible processors are installed.

How many PCI-E 4.0 lanes do the three x16 and three x8 slots provide in practice?

The board offers three PCI-E 4.0 x16 slots and three PCI-E 4.0 x8 slots for add-in cards, plus one M.2 M-key slot at PCI-E 4.0 x4.
