ASRock Rack Shows Single-Socket Board for Intel Diamond Rapids
The DMRD16-2L+ uses sixteen-channel memory and routes all PCIe I/O through MCIO connectors instead of standard card slots.
Updated on Nov. 7, 2026 in Data Centers
ASRock Rack showed the DMRD16-2L+, a single-socket board for Intel's Diamond Rapids Xeon platform, at OCP Summit 2026. The EEB-format board supports sixteen DDR5 slots and up to 16 MCIO x8 connectors rated for PCIe 6.0 or CXL 3.0.
Why it matters
The board's design reflects a shift toward MCIO-based connectivity for high-bandwidth I/O in server platforms rather than conventional PCIe card slots. Its support for MRDIMM memory at up to 12800MT/s points to the memory bandwidth demands of data center workloads.
The board provides up to 128 PCIe Gen6 or CXL 3.0 lanes through 16 MCIO x8 connectors, alongside a single M-key M.2 slot supporting PCIe 5.0 x4. Release timing and retail availability are not stated in the source.
The players
ASRock Rack
ASRock Rack is a server motherboard and platform subsidiary of ASRock that designs boards for data center and enterprise customers.
Intel
Intel is a U.S. semiconductor company that designs the Xeon server processors used in data center and enterprise computing.
The details
The DMRD16-2L+ uses a single DIMM per channel layout across its sixteen DDR5 slots and an ASPEED AST2700 BMC for management. It includes two 1GbE RJ45 ports powered by an Intel I350 controller and a 12-by-13-inch EEB form factor.
Timeline
ASRock Rack showed the DMRD16-2L+ at OCP Summit 2026 on November 7, 2026.
Under the Hood
The DMRD16-2L+ implements PCIe 6.0 and CXL 3.0, interconnect standards that enable higher-bandwidth links and memory pooling in server systems. By routing these links through MCIO connectors rather than standard card slots, the board follows a design pattern increasingly common in data center hardware.
The board's MCIO-based connectivity and large memory capacity are aimed at server builders and data center operators rather than general consumers. Its practical effect on those buyers depends on availability and pricing, which the source does not provide.
The takeaway
Server platforms are moving toward MCIO-based I/O and higher-speed memory modules to meet data center bandwidth needs. Buyers evaluating next-generation Xeon systems should watch for availability and pricing details for boards like the DMRD16-2L+.
