Dual-Socket SP5 Barebone for AMD EPYC 9004 and 9005

The 1U12E-TURIN2 is a 1U rackmount server barebone that accepts up to two AMD EPYC 9004 or 9005 series processors in Socket SP5. It provides 24 DDR5 4800 registered DIMM slots for up to 12 TB of memory and twelve hot-swap 2.5-inch bays wired for NVMe PCIe 5.0 x4 or SATA drives. A 1+1 redundant 1600 W 80-PLUS Platinum CRPS power supply is included.

Suited for dense dual-processor deployments

This platform fits workloads that demand two high-core-count CPUs, large memory capacity and twelve front-accessible NVMe drives in a single rack unit. It is not for buyers who need onboard networking faster than 1 GbE, more than two full-height PCIe 5.0 x16 slots, or support for processor families other than AMD EPYC 9004 and 9005.

Twelve hot-swap 2.5-inch NVMe PCIe 5.0 x4 drive bays

The defining specification is the twelve front bays, each wired for a PCIe 5.0 x4 NVMe device or a SATA drive. This density decides whether the chassis matches a storage-heavy, dual-socket build or whether a different bay count or interface is required.

Questions about this item

How do I install the EPYC processors into the dual SP5 sockets on this 1U barebone?

Open the socket latches, align the processor triangle with the socket corner, place the CPU gently, close the latch, then secure the retention frame using the supplied screws in a cross pattern.

Which components will need replacement first during the server's operational life?

The 1+1 80-PLUS Platinum 1600W CRPS power supplies and system cooling fans are field-replaceable units designed for hot-swap servicing without downtime.

What thermal limit appears first when both EPYC CPUs run at 240W TDP continuously?

The 1U chassis airflow and dual 1600W power supply cooling capacity set the practical ceiling before CPU throttling activates under sustained maximum load.
