GIGABYTE R283-ZF1-ACL1 barebone server 24 DDR5 2.5 NVMe SATA SAS

SKU CH-M9BS-75HM0 MPN R283-ZF1-ACL1

2U barebone server supporting dual AMD EPYC 9004/9005 processors, 24 DDR5 DIMM slots, four dual-slot Gen5 GPUs and sixteen 2.5-inch hot-swap drive bays

  • Supports up to four dual-slot Gen5 GPUs for accelerated workloads
  • Dual AMD EPYC 9005 and 9004 series processors deliver high core counts
  • 12-channel DDR5 architecture with 24 DIMM slots maximises memory bandwidth
  • Dual ROM architecture provides firmware redundancy and recovery
  • 16 hot-swap 2.5-inch bays support NVMe, SATA and SAS-4 storage

Dual EPYC 9004/9005 barebone

This 2U server barebone accepts two AMD EPYC 9004 or 9005 series processors. It targets organisations building dense GPU compute nodes for AI training or high-performance computing. The chassis provides four full-height PCIe Gen5 x16 slots for dual-slot accelerators.

Tool-less drive bays and GPU retention

Twelve 2.5-inch hot-swap bays accept Gen5 NVMe, SATA or SAS-4 drives without tools. GPU installation uses the four FHFL slots; the main risk is exceeding the platform power budget when four dual-slot cards are fitted. Memory population follows the 12-channel DDR5 RDIMM layout across 24 slots.

24 DDR5 RDIMM slots

The board exposes 24 DDR5 RDIMM sockets in a 12-channel arrangement per processor pair. This capacity ceiling decides whether the system fits a given memory footprint. Buyers needing more than 24 modules must choose a different platform.

Questions about this item

How do I verify the 24 DDR5 RDIMM slots are populated correctly after setup?

The system supports 12-channel DDR5 memory across 24 DIMM slots; check the BIOS or management console to confirm all installed modules are detected and running at the expected speed.

What drive types fit the 2.5-inch hot-swap bays and do I need separate caddies?

The chassis provides 4 bays for Gen5 NVMe or SATA or SAS-4, 4 bays for Gen5 NVMe only, and 8 bays for SATA or SAS-4; caddies are included with the barebones unit.

Which AMD EPYC processor series should I choose between the 9004 and 9005 for this 2U server?

Both the 9004 and 9005 series are supported in the dual-socket configuration; select the 9005 series for newer core architecture or the 9004 series for established platform maturity.
