ATX server board for EPYC SP3

The ROMED8-2T is an ATX form-factor server motherboard designed for a single AMD EPYC processor in the SP3 socket. It targets system builders who need high core counts and eight-channel memory in a standard 12.0 by 9.6 inch layout. The board supports EPYC 7002 and 7003 series CPUs, including models with 3D V-Cache technology when a BIOS update is applied.

Eight DIMM slots and flexible PCIe layout

Eight 288-pin DDR4 slots accept RDIMM, LRDIMM, 3DS and NVDIMM-N modules up to 256 GB per DIMM with ECC across eight channels. Seven PCIe 4.0 x16 slots provide dense accelerator or networking capacity, while two OCuLink ports and two M.2 slots share bandwidth with the second PCIe slot via jumpers. Ten SATA 6.0 Gb/s ports and two Mini-SAS HD connectors handle high-volume storage. Dual 10 GbE RJ45 ports use an Intel X550-AT2 controller, and a dedicated IPMI LAN port enables remote management.

Single SP3 socket limits CPU choice to one processor

Only one EPYC CPU can be installed, so workloads requiring dual-socket memory capacity or PCIe lane count must look elsewhere. The board delivers up to 3200 MHz DDR4 speeds and 10 GbE networking out of the box, but buyers needing two CPUs or a different socket type cannot use this platform.

Questions about this item

What PCIe generation does the SP3 socket provide for the seven x16 slots, and what bandwidth does that cap each slot at?

The SP3 socket delivers PCIe 4.0 across seven x16 slots, capping each at 4.0 x16 bandwidth.

What chassis clearance and power connectors does the ATX 12.0 x 9.6 inch board require to fit and start?

It needs an ATX chassis with 12.0 x 9.6 inch clearance plus 24-pin, 8-pin, 4-pin and 6-pin power connectors.

How do you enable the second M.2 slot and the two OCuLink ports, and which jumper is often missed?

Move the jumper on slot 2 to share its lanes; the slot-2 jumper is the step most builders overlook.
