1U AMD EPYC 9005/9004 barebone

This 1U rackmount barebone accepts a single AMD EPYC 9005 or 9004 series processor in the SP5 socket. It targets general-purpose, cloud-native and technical computing workloads that need high core density and memory bandwidth in a compact form factor. The system ships without CPU or memory installed.

Verify SP5 processor and DDR5 6000 RDIMMs

Confirm the chosen EPYC 9005 or 9004 CPU matches the SP5 socket and your core-count requirements. You must supply up to twelve DDR5 6000 RDIMMs across the twelve 288-pin slots to populate the twelve memory channels. No storage or M.2 drive is included, so plan for NVMe, SATA or SAS-4 devices.

Twelve hot-swap bays plus PCIe Gen5 expansion

Twelve 2.5-inch front bays support Gen5 NVMe, SATA and SAS-4 hot-swap drives, freeing internal cabling and simplifying service. Two full-height half-length PCIe Gen5 x16 slots and two OCP NIC 3.0 PCIe Gen5 x16 slots provide high-speed networking or accelerator capacity. Dual 1300W 80 PLUS Platinum redundant power supplies deliver resilience.

Questions about this item

Does the R163-Z35-AAC1 ship with a processor, memory or drives, or must I buy them separately?

The barebone arrives without an AMD EPYC 9005 or 9004 CPU, without DDR5 6000 RDIMMs for the 12 slots, and without storage for the 12 hot-swap bays or the M.2 slot; you supply all three.

Which AMD EPYC generation fits the SP5 socket in this 1U server?

The SP5 socket supports both AMD EPYC 9004 and 9005 series processors, up to 192 cores, so you choose a 4th- or 5th-gen part that matches your core-count and cache needs.

What does the 1300W Platinum redundant power rating mean for daily operation?

Two 1300W 80 PLUS Platinum units share the load; if one fails the other continues to power the CPU, 12 DDR5 channels, 12 drive bays and both PCIe Gen5 x16 slots without interruption.
