4U barebone for dual EPYC CPUs
This 4U rackmount server barebone is built for AI, machine learning and high-performance computing workloads. It accommodates two AMD EPYC 7002 or 7003 series processors in Socket SP3 with a thermal design power of up to 280W each. No CPUs or memory are installed, so integrators choose the exact configuration required.
Suits HPC builders needing dense GPU and storage
The chassis supports up to eight full-height full-length dual-slot PCIe 4.0 x16 cards plus additional front-access slots and an OCP 3.0 mezzanine. Twelve hot-swap 3.5-inch drive bays provide high local storage density. Buyers who require single-socket operation, smaller form factors or integrated GPUs should evaluate other platforms.
Verify CPU BIOS revision
A BIOS update is mandatory for EPYC 7003 series processors; confirm firmware availability before deployment. Memory must be DDR4 3200 registered RDIMM up to 64GB per DIMM or LRDIMM up to 256GB per DIMM across 32 slots. Ensure the power infrastructure can deliver 1600W redundant CRPS supply.

Questions about this item
Which AMD EPYC processors are compatible with the 4U8G-ROME2/2T dual Socket SP3 board?
The board supports dual AMD EPYC 7002 and 7003 series processors up to 280W TDP. EPYC 7003 series CPUs require a BIOS update from ASRock Rack Technical Support before installation.
Can I keep my existing DDR4 3200 RDIMM or LRDIMM modules when moving to this 32-slot server?
Yes. The system accepts DDR4 3200 registered DIMMs: RDIMMs up to 64GB and LRDIMMs up to 256GB per module across 32 x 288-pin slots.
How do I verify the 3+1 redundant 1600W CRPS power supplies are operating correctly after build?
Check the front-panel PSU status LEDs; all four units should show solid green. The Aspeed AST2500 BMC also reports each supply's health and redundancy state via IPMI.
