ASRock Rack’s DMRD16-2L+ motherboard for Intel Diamond Rapids Xeon CPUs features 16 DDR5 slots, 16 memory channels, and 128 PCIe Gen6 lanes.

ServeTheHome identified the ASRock Rack DMRD16-2L+ as a motherboard for Intel’s Diamond Rapids Xeon central processing units (CPUs). The supplied article summary describes a motherboard platform, rather than a complete server, accelerator, rack, or cluster.

Its memory configuration comprises 16 DDR5 slots and 16 memory channels. These are distinct specifications: the summary provides both counts but does not state an installed memory capacity or measured memory bandwidth.

The board also provides 128 Peripheral Component Interconnect Express Generation 6 (PCIe Gen6) lanes through Mini Cool Edge IO (MCIO) connections. The supplied excerpt does not include benchmark results, pricing, or commercial availability, so it supports a hardware-specification update rather than a performance or deployment claim.
