GIGABYTE

GIGABYTE MZ33-AR1 Rev. 3.x server motherboard

SKU CH-SX0F-ES3B2

E-ATX server board for AMD EPYC 9005 and 9004 CPUs with 12-channel DDR5 across 24 DIMMs, dual 10GbE LAN, multiple PCIe Gen5 MCIO links and four x16 slots

  • Supports up to 192-core AMD EPYC 9005 processors
  • 12-channel DDR5 with 24 DIMM slots for high memory capacity
  • Dual 10Gb/s LAN via Broadcom BCM57416 for fast networking
  • Six MCIO 8i connectors with PCIe Gen5 x8 or SATA options
  • Four PCIe Gen5 x16 slots plus M.2 PCIe Gen4 x4 for expansion

AMD EPYC 9005 / 9004 server motherboard

The GIGABYTE MZ33-AR1 Rev. 3.x is an E-ATX board built for single-socket AMD EPYC 9005 and 9004 series processors. It targets data-centre workloads such as general-purpose compute, cloud-native services and technical computing where high core counts and memory bandwidth are required.

Dual 10GbE LAN plus mixed MCIO and M.2 storage

Two Broadcom BCM57416 10 Gb/s ports provide high-speed networking out of the box. Six MCIO 8i connectors deliver a mix of PCIe Gen5 x8, PCIe Gen4 x8 and SATA pathways, while a single M.2 slot adds PCIe Gen4 x4 connectivity for fast local storage.

24 DDR5 RDIMM slots across 12 channels

The board supports up to 24 DDR5 RDIMM modules in a 12-channel configuration, matching the 192-core ceiling of the latest EPYC processors. Four full-length PCIe Gen5 x16 expansion slots give headroom for multiple accelerators or high-bandwidth NICs, though the single-socket design limits total lane count compared to dual-socket platforms.

Questions about this item

Will the 24 DDR5 DIMM slots need periodic reseating or replacement?

The 24 DDR5 RDIMM slots are fixed on the board and do not require routine reseating; only a failed module would need swapping.

What limits sustained performance on the 12-channel DDR5 memory subsystem?

The 12-channel DDR5 architecture scales bandwidth with all 24 slots populated, so memory throughput is the first ceiling under continuous load.

How much heat do the dual 10GbE Broadcom BCM57416 ports add during all-day operation?

The BCM57416 controllers are integrated on the motherboard and draw minimal power, so they add negligible heat to the chassis airflow.
