GIGABYTE MZ23-SU0 server motherboard AMD EPYC 9005/9004 CEB UP

SKU CH-ANY5-3QJTT MPN MZ23-SU0

Supports single AMD EPYC 9005/9004 processors with twelve DDR5 RDIMM slots and five PCIe Gen5 x16 expansion slots

  • Supports single AMD EPYC 9005 or 9004 series processors
  • 12-channel DDR5 RDIMM architecture across 12 DIMM slots
  • Dual 1 Gb/s LAN ports driven by Intel I350-AM2 controller
  • Five PCIe Gen5 x16 expansion slots for high-bandwidth add-in cards
  • Two MCIO 8i connectors providing PCIe Gen5 x8 or SATA connectivity

Single-socket EPYC server board

The GIGABYTE MZ23-SU0 is a CEB-form-factor motherboard built for single AMD EPYC 9005 or 9004 series processors. It targets deployments that need high core density in a single-node chassis. Twelve DDR5 RDIMM slots provide 12-channel memory bandwidth for memory-intensive workloads.

Suited for dense compute nodes.

This board suits builders who need up to 5 PCIe Gen5 x16 slots and 12 memory channels in one socket. It does not suit buyers who want dual-socket scaling, on-board networking faster than 1 GbE, or more than two M.2 PCIe Gen3 x2 sockets.

Twelve DDR5 channels set the memory ceiling

The defining specification is the 12-channel DDR5 RDIMM design with 12 DIMM slots. This capacity dictates maximum memory bandwidth and total system RAM, making it the primary factor when matching the board to a workload.

Questions about this item

How much power does the MZ23-SU0 draw when running an EPYC 9005 processor continuously?

The board supports single EPYC 9005 or 9004 series processors with a 12-channel DDR5 design across 12 DIMM slots, but continuous power draw depends on the specific CPU TDP and workload configuration.

Which components must I already have to boot this motherboard?

You need a compatible EPYC 9005 or 9004 series processor, DDR5 RDIMM modules for the 12 DIMM slots, and a power supply with sufficient EPS connectors for the CPU and board.

Will my existing PCIe Gen4 add-in cards work in the five PCIe Gen5 x16 slots?

Yes, the five PCIe Gen5 x16 expansion slots are backward compatible with PCIe Gen4 cards, which will operate at Gen4 speeds when installed.
