Server Motherboard for AMD AM5

The MSI D3051GB2N-1G is a uATX server motherboard built around the AMD B650 chipset. It accepts a single AMD Ryzen 7000 or 9000 series processor, or an EPYC 4004 or 4005 series CPU, with a TDP limit of 170W. The board measures 9.6 by 9.6 inches and ships new.

Suited for ECC Memory and Remote Management

This board suits builders who need ECC DDR5 memory support across four DIMM slots with a maximum of 48GB per module. Integrated ASPEED AST2600 graphics provide IPMI and Redfish remote management, plus a dedicated 1GbE server management LAN port. It is not for systems requiring 10GbE networking, more than two M.2 NVMe drives, or a second CPU socket.

Single AM5 Socket with 170W TDP Limit

The single AMD Socket AM5 restricts the platform to one processor with a maximum 170W TDP. This thermal ceiling determines which Ryzen or EPYC models can be installed without throttling. Verify your chosen CPU stays within this limit before purchase.

Questions about this item

Should I populate one DIMM per channel or two DIMMs per channel on this board?

With one DIMM per channel the board runs DDR5 at 5200 MT/s; filling all four slots drops the speed to 3600 MT/s.

What does the 170 W TDP limit mean for my CPU choice?

Any single AM5 Ryzen 7000 or 9000 series processor rated up to 170 W is supported.

How fast are the M.2 slots when both are used?

Each M.2 2280/22110 slot provides PCIe 4.0 x4 bandwidth; the second slot shares its link with the PCIe 4.0 x8 expansion slot.
