The Gigabyte MZ31-AR0 is a single-socket server motherboard for AMD EPYC 7002 (Rome) processors on the SP3 socket, with support for up to 64 cores per CPU. It stands out for holding full 3200 MHz DDR4 memory speed even with two DIMMs per channel, where many competing EPYC boards drop to lower speeds. It carries PCIe 4.0, dual 10GbE networking and eight memory channels, aimed at big data, HPC and cloud workloads. It is a bare board for builders and integrators, not a consumer desktop part, and its feature set is competitive with other single-socket EPYC 7002 platforms.

The Gigabyte MZ31-AR0 is a server motherboard with a Socket SP3 for AMD EPYC 7002 Series (Rome) processors. These processors are built on 7nm process technology and offer up to 64 Zen 2 cores per CPU. They support PCIe Gen 4.0 with bandwidth of up to 64GB/s, twice that of PCIe Gen 3.0.
The board supports 8-channel DDR4 RDIMM or LRDIMM memory at up to 3200MHz with 1 DIMM per channel. Gigabyte states that 3200MHz is also supported with 2 DIMMs per channel. It has dual onboard 10Gb network ports and onboard M.2 storage support with transfer speeds of up to 32 Gb/s. It supports Trusted Platform Modules (TPM 2.0).
Management runs through an AMI MegaRAC SP-X BMC with a browser-based interface, RESTful API support including Redfish, and an HTML5 iKVM remote client with no extra license. The BIOS can be updated through the BMC without installing CPUs, memory, drives or an OS, and without powering on the system. Fan speeds adjust automatically based on temperature sensors, and custom fan profiles can be created. The board follows RoHS regulations in effect July 2017.
