MZ33-AR1 Gigabyte E-ATX Single SP5 24 DIMM Slots MZ33-AR1 REV. 3 Server Mainboard

E-ATX AMD EPYC SP5 Server Motherboard engineered for PCIe 5.0 expansion and dense storage with the MZ33-AR1 Gigabyte

The MZ33-AR1 Gigabyte (MZ33-AR1 REV. 3) is an E-ATX server motherboard for single-socket AMD EPYC 9004/9005-class SP5 platforms, designed for compute nodes that prioritize I/O throughput and platform consistency. It supports up to 500W CPUs and pairs the EPYC IOD architecture with 12-channel DDR5 ECC to sustain high core-count consolidation for virtualization and general enterprise workloads.

For scalable connectivity, the MZ33-AR1 Gigabyte exposes 4 PCIe 5.0 x16 mechanical slots to accommodate high-bandwidth NICs, HBAs, and accelerator add-in cards without forcing lane compromises. Storage topology is optimized for mixed all-flash and capacity tiers: multiple NVMe ports for low-latency datasets, a large SATA domain for bulk media, plus an M.2 PCIe 4.0 x4 boot option to keep front-access bays available for applications. Integrated dual 10GbE and an AST2600 BMC provide out-of-band control aligned with remote operations.

Why Choose the MZ33-AR1 Gigabyte?

The MZ33-AR1 Gigabyte is built for density-to-performance efficiency in single-socket EPYC deployments where PCIe 5.0 expansion and storage fan-out define platform value. It enables predictable scale-out across clusters, supporting standardized management, flexible adapter selection, and reliable operation for enterprise lifecycle planning.

Gigabyte designs server platforms with a focus on validated signal integrity, serviceable layouts, and firmware maturity for modern data centre requirements. The board’s management stack and enterprise I/O design support repeatable builds and controlled change management across production environments.
