ASRock Rack previews Diamond Rapids board packing up to 4 TB of DDR5 memory

At the OCP Global Summit 2026, ASRock Rack showcased the DMRD16-2L+, a single-socket motherboard engineered for Intel's upcoming Diamond Rapids Xeon 7 processors. The 12 × 13-inch board uses an EEB form factor that is comparable in size to enthusiast E-ATX designs, allowing it to fit into select standard PC cases despite its enterprise feature set. ASRock Rack has not yet revealed pricing or release timing for the hardware. [1][2]

The platform relies on 16 memory channels with one DIMM per channel, accommodating up to 4 TB of memory when equipped with 256 GB MRDIMM 2U modules. The board supports RDIMMs of up to 128 GB at speeds reaching 8000 MT/s, alongside faster MRDIMMs at up to 12800 MT/s. Instead of standard PCIe expansion slots, the board supplies 16 MCIO x8 connectors that support PCIe 6.0 and CXL 3.0 across 128 lanes. Connectivity also includes one PCIe 5.0 x4 M.2 slot, two 1GbE network ports, and an Aspeed AST2700 controller to handle server management. [1][2]

The platform is aimed at demanding AI, cloud, and high-performance server tasks. Intel says Diamond Rapids processors are currently sampling and projected to ramp up in 2027, with previously disclosed configurations featuring up to 256 P-cores and 1.28 GB of last-level cache. While primary demand sits in datacenters, the board's compact dimensions and high capacity could also appeal to workstation builders running local artificial intelligence workloads. [1]
