1U EPYC barebone for general-purpose workloads

The ASRock Rack 1U4LW-ROME/2T is a 1U rackmount server barebone designed for general-purpose deployments. It accepts a single AMD EPYC 7002 or 7003 series processor in a Socket SP3 socket. No CPU or memory is installed, so the buyer provides both.

Suits single-socket builds

This platform suits integrators building a single-processor server that needs front-accessible 3.5-inch hot-swap bays and internal 2.5-inch SATA bays. It is not for buyers who need dual-processor support, more than one full-height half-length PCIe 4.0 x16 slot, or 10 Gigabit Ethernet beyond the two onboard ports.

Single Socket SP3 processor limit

The chassis supports a maximum of one processor, fixing the compute ceiling at a single EPYC CPU. That constraint decides whether the barebone matches the intended workload.

Questions about this item

Should I choose the 7002 or 7003 series EPYC processor for this barebone?

Both series fit the SP3 socket, but the 7003 series requires a BIOS update before it will boot. If you want to avoid that step, select a 7002 series CPU; otherwise plan the update first.

What does the 10 Gigabit LAN figure mean once the server is running?

The Intel X710-AT2 controller provides two RJ45 ports that each negotiate up to 10 Gb/s over copper cabling, so throughput is limited by the 10 GbE link and the PCIe 4.0 x16 slot it occupies.

What does the PCIe 4.0 x16 slot cap in practice?

The single full-height half-length slot runs at PCIe 4.0 x16 electrical, so any add-in card is limited to that generation and lane width; the slot shares the CPU root complex, so total bandwidth cannot exceed the x16 ceiling.
