Product description
Gigabyte MZ33-AR1 (Rev. 3.x) – Single-Socket SP5 Platform for 500W AMD EPYC 9005 with 24-DIMM Architecture
The Gigabyte MZ33-AR1 (Rev. 3.x) is an elite server motherboard designed to extract maximum performance from single-socket infrastructure. Engineered for the AMD EPYC 9005 “Turin” and 9004 “Genoa” series, this platform utilizes a deep E-ATX form factor (305W x 330D mm) to accommodate a robust power delivery system capable of sustaining cTDP levels up to 500W. It is built for extreme compute density, making it the ideal foundation for high-frequency trading, scientific simulation, and AI workloads that demand peak processor frequencies.
Unrivaled Memory Density: 24 DIMM Slots
A defining characteristic of the MZ33-AR1 is its massive memory capacity on a single CPU. It fully activates the 12-channel memory controller of the SP5 socket using a “2 DIMMs Per Channel” (2DPC) topology. With 24 DIMM slots available, system architects can populate up to 6TB of DDR5 ECC 3DS RDIMM memory. This allows memory-intensive applications, such as in-memory databases and large-scale virtualization, to run without the latency penalties associated with dual-socket communications.
Advanced MCIO Storage Ecosystem
The board replaces legacy storage headers with a high-density MCIO cabling architecture, optimizing airflow and signal integrity. It offers a total of six MCIO connectors configured for versatility:
- Gen5 Performance: Three MCIO 8i ports (PCIe Gen5 x8) are dedicated purely to high-speed NVMe or accelerator connectivity.
- Hybrid Flexibility: Two MCIO 8i ports (PCIe Gen5 x8 / SATA) allow users to connect either next-gen NVMe drives or legacy SATA arrays (BIOS configurable).
- Legacy Support: One MCIO 8i port (PCIe Gen4 x8) provides additional lanes for standard storage or auxiliary devices.
Native 10-Gigabit Networking
Connectivity is handled by the enterprise-grade Broadcom BCM57416 controller, providing dual 10GBase-T LAN ports natively. This ensures immediate integration into high-speed corporate networks and fast storage fabrics without occupying a PCIe slot.
PCIe 5.0 Expansion and Management
For external accelerators, the board provides four PCIe 5.0 x16 slots, offering full bandwidth for professional GPUs and FPGA units. System supervision is centralized via the ASPEED AST2600 BMC, enabling secure IPMI 2.0 access and KVM-over-LAN for remote “lights-out” management. A dedicated M.2 slot (PCIe Gen3 x4) is also included for reliable OS booting.
Technical Specifications Summary
- Processor Support: AMD EPYC 9005/9004 (Socket SP5) / Up to 500W cTDP
- Memory Topology: 24 DIMM Slots, 12-Channel DDR5 ECC (Up to 6TB)
- Network Interface: 2x 10GbE (Broadcom BCM57416) + Dedicated IPMI LAN
- Expansion Slots: 4x PCIe 5.0 x16 slots
- Storage I/O: 5x MCIO Gen5 (2x SATA capable), 1x MCIO Gen4, 1x M.2 Gen3

Overview and Analysis of the Gigabyte MZ33-AR1 Motherboard
The Gigabyte MZ33-AR1 is a single-socket E-ATX server motherboard designed for the latest AMD EPYC 9004 (Genoa) and 9005 (Turin) processors based on the SP5 socket (LGA 6096). This solution is intended for building high-performance servers that require a balance between computational power, massive memory capacity, and I/O capabilities, but within a single-socket configuration.
The board is oriented towards the following tasks:
- Virtualization and cloud computing (thanks to the high core count of EPYC and memory capacity).
- In-Memory databases and big data analytics.
- AI inference and machine learning model training.
- High-Performance Computing (HPC).
A key feature of the MZ33-AR1 is support for 24 DIMM slots, allowing for the installation of up to 6 TB of DDR5 RAM, providing bandwidth comparable to dual-socket systems.
Comparative Table of Technical Specifications
Below is a comparison of the Gigabyte MZ33-AR1 with its closest competitors on the SP5 platform.

Analysis of the Strengths of Gigabyte MZ33-AR1
Based on the technical specifications, clear advantages of the Gigabyte MZ33-AR1 can be highlighted, especially in comparison with single-processor competitors (Supermicro H13SSL series):
- Unprecedented Memory Capacity: The board is equipped with 24 DIMM slots, supporting up to 6 TB of RAM. This is twice as much as ATX format competitors (Supermicro H13SSL-NT/N), which are limited to 12 slots and 3 TB of memory. This makes the MZ33-AR1 an ideal choice for tasks critical to memory volume.
- Maximum Performance (TDP): Support for processors with a TDP of up to 500W (including the 9005 series models) guarantees the ability to install the most powerful chips in the EPYC lineup without the risk of throttling or instability, while many competitors are limited to a 400W threshold.
- High-Speed Network: The presence of two 10Gb/s (10 Gigabit Ethernet) ports ensures high network bandwidth “out of the box”, which is important for modern data centers and virtualization clusters.
- E-ATX Form Factor: Although it requires a more spacious chassis compared to ATX, this size allows for 24 memory slots and better cooling of VRM components, which is critical for systems of this level.
Conclusion
The Gigabyte MZ33-AR1 is the ultimate solution for single-socket servers on the SP5 platform. It blurs the line between single- and dual-processor systems, offering huge memory capacity and support for the hottest processors. This is the best choice for those who want to get the maximum out of a single AMD EPYC CPU without overpaying for a dual-socket platform, while still demanding Enterprise-level functionality.
Product FAQ
This motherboard features the SP5 socket and is designed to work with AMD EPYC 9004 series processors (Genoa, Genoa-X, Bergamo) and the latest AMD EPYC 9005 (Turin). It supports CPUs with a Thermal Design Power (TDP) of up to 400W and even higher, provided there is adequate cooling.
Thanks to its 24 DIMM slots, the board supports the installation of up to 6 TB of DDR5 RDIMM or 3DS RDIMM standard memory. The memory operates in 12-channel mode, ensuring extreme bandwidth.
Most likely, no. The board is made in the E-ATX form factor (305W x 267D mm), which is significantly wider than standard ATX. Its installation requires a specialized server case or chassis that supports boards of this size and provides proper cooling for the VRM zone and the processor.
Yes, the Gigabyte MZ33-AR1 is equipped with two high-speed 10 Gigabit Ethernet (10GbE Base-T) ports, allowing for fast network connectivity without the need to purchase additional network cards.
Absolutely. The board provides support for the PCIe Gen5 interface, allowing the use of the most modern and fastest NVMe drives, network cards, and computing accelerators with double the bandwidth compared to PCIe 4.0.
The model is equipped with a dedicated management port (MLAN) and an ASPEED AST2600 BMC controller. This provides full remote administration functionality (IPMI 2.0, Redfish), including console access (KVM over IP) and hardware status monitoring regardless of OS operation.
No, the board works only with server-grade registered DDR5 RDIMM or 3DS RDIMM memory with Error Correction Code (ECC) support. Standard UDIMM memory used in home PCs is not supported.
The board has 4 PCIe x16 (Gen5) slots and 1 PCIe x8 (Gen5) slot, which allows for the installation of several single-slot or dual-slot expansion cards. However, the physical dimensions of the cards and the available space in the chassis should be taken into account.
Yes, given the high power consumption of EPYC processors and the large amount of memory, it is recommended to use a server power supply that supports EPS12V standards and has sufficient wattage (often 1000-1200W and above), with the necessary number of connectors to power the CPU (usually 2x 8-pin).
