Dual-socket EPYC server board

The ASRock Rack ROME2D16-2T is an EEB form-factor motherboard built for dual AMD EPYC 7002 or 7003 series processors in SP3 sockets. It provides sixteen DDR4 DIMM slots across two CPU channels, supporting registered RDIMM, LRDIMM and NVDIMM-N modules up to 256 GB per slot. Five PCIe 4.0 x16 slots and one x8 slot offer high-bandwidth expansion for compute or storage accelerators.

Suited for dense compute and storage nodes

This board targets builders assembling high-core-count servers, virtualization hosts or storage appliances that need dual 10 GbE and extensive PCIe 4.0 lane count. It is not a fit for single-socket workstations, systems requiring consumer CPUs, or chassis limited to ATX or smaller form factors. Buyers needing integrated graphics beyond basic Aspeed AST2500 output should look elsewhere.

Sixteen DDR4 slots with 256 GB per DIMM ceiling

The defining specification is the sixteen-slot memory subsystem, accepting DDR4 RDIMM up to 64 GB, LRDIMM up to 128 GB and 3DS modules up to 256 GB each. This capacity ceiling decides whether the platform can meet a given workload's memory footprint before any other feature is considered.

Highlights

  • Dual SP3 sockets scale compute with AMD EPYC 7002 and 7003 processors
  • Sixteen DDR4 DIMM slots support up to 256 GB per module for massive memory capacity
  • Five PCIe 4.0 x16 slots plus one x8 slot enable high-bandwidth expansion cards
  • Dual 10 GbE Intel X550-AT2 ports plus dedicated IPMI provide fast, managed networking
  • EEB 12" x 13" form factor fits standard server chassis for dense deployments

Questions about this item

What EEB chassis dimensions and mounting pattern does the ROME2D16-2T require?

The board follows the EEB 12" x 13" form factor, so the chassis must accept that footprint and the standard EEB mounting holes.

Which BIOS version must be flashed before installing an EPYC 7003 processor with 3D V-Cache, and how is it applied?

A BIOS update is required for EPYC 7003 series processors with AMD 3D V-Cache Technology; apply it via the dedicated IPMI port or the BMC web interface before seating the CPUs.

What is the maximum capacity per DIMM slot for RDIMM, LRDIMM and 3DS modules on this board?

Each of the 16 DDR4 slots supports up to 64 GB RDIMM, 128 GB LRDIMM or 256 GB 3DS RDIMM/LRDIMM modules.
