ASRock Rack DMRD16-2L+ motherboard supports 4 TB of DDR5 memory in standard EEB case

ASRock Rack's DMRD16-2L+ motherboard was unveiled during OCP Global Summit 2026. It's a high-density motherboard that doesn't break from standard server form factor. The platform is targeted to support up to 4 TB of DDR5 RAM per CPU.

ASRock Rack's new high-density motherboard supports 4 TB of DDR5 memory in a standard EEB form factor

That's important because it means fewer CPU sockets will be needed to handle high memory requirements. This configuration will be very important for people trying to keep socket costs down on huge datasets.

Specifications

• Form Factor: EEB (12 x 13-inch)
• Memory Capacity: Up to 4 TB
• Memory Slots: 16 DIMM slots
• Processor Support: Intel Diamond Rapids Xeon 7
• Expansion Connectors: 16 MCIO x8 connectors

ASRock Rack's DMRD16-2L+ motherboard is a specially designed platform for Intel's future Diamond Rapids Xeon 7 processors. The motherboard is 12 x 13 inches or EEB form factor. So it'll fit in some standard PC cases. The motherboard dimensions means it can be used in standard PC cases that are easier to obtain.

It's a high-density motherboard with 16 memory slots. It's intended to hit its high memory density targets. It supports RDIMM modules up to 128 GB with 8000 MT/s.

It also supports high-speed MRDIMM up to 12800 MT/s. It supports 256 GB MRDIMM 2U modules.

It has 16 MCIO x8 slots. They can support PCIe 6.0 and CXL 3.0. The motherboard provides 128 lanes for storage, networking, and accelerators.

There are 2x 1GbE network ports. It includes an Aspeed AST2700 management controller.

Intel Diamond Rapids is due to ramp in 2027. Intel has yet to announce an exact date. ASRock Rack has not yet provided pricing or availability details for the DMRD16-2L+.

The platform could theoretically offer up to 1.6 TB/s of memory bandwidth. It would need to use 2nd gen MRDIMM with 12800 MT/s.
