MZ31-AR0 Gigabyte

Gigabyte E-ATX Server Motherboard engineered for AMD EPYC SP3 single-socket density with SKU 9MZ31AR0MR-00

Gigabyte positions the 9MZ31AR0MR-00 as an E-ATX server motherboard for AMD EPYC SP3 (LGA4094) single-socket platforms where predictable throughput and platform consolidation matter. The EPYC SoC approach reduces chipset dependency while enabling a balanced I/O profile for virtualization hosts, edge services, and general compute nodes that need consistent PCIe 3.0 lane availability.

The board implements an 8-channel DDR4 memory architecture with 16 DIMM slots, supporting up to 2TB capacity and up to 2666 MT/s to sustain VM density and memory-resident caching without forcing a dual-socket footprint. For expansion, Gigabyte provides 4 PCIe 3.0 x16 slots (x16 electrical) and 3 PCIe 3.0 x8 slots (x8 electrical) to accommodate NICs, storage HBAs, and accelerator-class adapters typical in SDS and infrastructure stacks. Storage is optimized for high-bay SATA designs via 16 SATA ports plus a PCIe 3.0 x4 M.2 slot for boot or metadata tiers, while integrated dual 10GbE SFP+ and onboard 1GbE support segmented service and management networks.

Why Choose the Gigabyte?

Gigabyte delivers a pragmatic single-socket architecture that maximizes usable I/O per rack unit while keeping platform power, cooling, and licensing complexity under control. With integrated IPMI/BMC management and TPM support, the Gigabyte design aligns with remote operations, secure provisioning, and scalable rollouts across edge and core clusters.

Gigabyte engineering emphasizes stable firmware behavior, serviceable board layout, and compatibility with standard data centre practices including out-of-band management via ASPEED AST2500, predictable SATA topology, and deterministic PCIe slot mapping for repeatable builds.

Key Applications:

Single-socket virtualization hosts
Software-defined storage nodes
High-bay SATA storage servers
10GbE edge and core infrastructure services
General-purpose compute

At Happyware - Server Hardware you benefit from non-binding offers tailored precisely to your needs and the option to extend the warranty up to 6 years, supporting standardized procurement and long-term platform continuity for enterprise deployments.
