1U barebone with SP5 socket

The ASRock Rack 1U4L4E-GENOA/2T is a 1U rackmount barebone server designed for general-purpose workloads. It accepts a single AMD EPYC 9004 series processor in an SP5 socket and provides eight 288-pin DDR5 4800 memory slots. No CPU or memory is installed, so the builder supplies both to match the target application.

Suits storage-dense single-socket builds

This chassis fits four hot-swap 2.5-inch bays that each take NVMe PCIe 5.0 x4 or SATA drives, plus four hot-swap 3.5-inch SATA bays. Two M.2 M-key slots add PCIe 4.0 x4 capacity. Builders needing more than one processor socket or more than eight DIMM slots should look at a different platform.

Sustained load on Platinum power

A redundant 1+1 750 W 80-PLUS Platinum power supply feeds the system during continuous operation. The Aspeed AST2600 with 512 MB DDR4 handles remote management without loading the main CPU. Dual 10 GbE ports from an Intel X550-AT2 controller maintain network throughput under prolonged traffic.

Questions about this item

Which AMD EPYC 9004 series processor and DDR5 4800 RDIMMs must I supply to complete this barebone?

Choose a single SP5 (LGA 6096) EPYC 9004 or 97x4 CPU and populate up to eight 288-pin DDR5 4800 RDIMM slots, each supporting up to 96 GB per DIMM or 512 GB per 3DS DIMM.

Can I keep using my existing 2.5" U.3 NVMe and 3.5" SATA drives in the hot-swap bays?

Yes, the four 2.5" bays accept NVMe (PCIe 5.0 x4) or SATA drives, and the four 3.5" bays accept SATA drives, so current U.3 NVMe and 3.5" SATA media will work.

How do I confirm the system is operating correctly after installing the CPU, memory and drives?

The Aspeed AST2600 BMC with 512 MB DDR4 provides IPMI remote console and sensor monitoring, while the Intel X550-AT2 dual 10 GbE ports show link status for network verification.
