1U Dual-Socket SP5 Barebone Server

The ASRock Rack 1U12E-TURIN2/EVAC is a 1U rackmount barebone server designed for dual AMD EPYC 9005 and 9004 series processors. It supports up to two CPUs with a thermal design power of up to 360W each, conditionally supported. The platform targets general-purpose server workloads requiring high core density and memory capacity.

Suits high-density compute, not GPU-heavy builds

This server suits deployments needing twelve hot-swap 2.5-inch NVMe drive bays and twenty-four DDR5 6400 RDIMM slots in a 1U form factor. It is not for buyers who need more than two full-height PCIe 5.0 x16 expansion slots or onboard networking faster than 1 Gigabit Ethernet. The Aspeed AST2600 provides basic graphics only.

Twelve PCIe 5.0 NVMe bays set storage density

The single specification that decides fit is the twelve hot-swap 2.5-inch drive bays wired for PCIe 5.0 x4 NVMe. This density defines the storage ceiling for the chassis. Buyers needing more bays or different drive interfaces must choose a different platform.

Questions about this item

Does the 1U12E-TURIN2/EVAC ship with any CPUs, memory or drives, and what must I add to make it run?

The barebone arrives without any CPUs, DDR5 6400 RDIMMs or NVMe drives. You must supply up to two AMD EPYC 9005 or 9004 processors, registered DDR5 6400 memory for the 24 DIMM slots, and NVMe SSDs for the 12 hot-swap 2.5-inch bays. The 2000W redundant power supply and Aspeed AST2600 management GPU are already installed.

Which AMD EPYC 9005 or 9004 models fit the dual SP5 sockets and the 360W TDP limit?

Both sockets accept any AMD EPYC 9005 or 9004 series processor, including 3D V-Cache variants, provided each CPU does not exceed the conditionally supported 360W TDP. Choose core counts and clock speeds that match your workload while staying within that thermal envelope.

What usable throughput can I expect from the 12 NVMe bays wired for PCIe 5.0 x4 once the server is populated?

Each of the 12 front 2.5-inch bays delivers a full PCIe 5.0 x4 link to the CPU, so every installed NVMe SSD can run at its rated PCIe 5.0 x4 speed without sharing bandwidth with other bays.
