Description

The Gigabyte MS73-HB1 Extended ATX motherboard is a top-tier enterprise-class offering (Server/Enterprise), specially designed to accommodate dual 4th and 5th Gen Intel® Xeon® Scalable processors with an LGA4677 socket. It delivers unmatched computing power and expanded bandwidth for demanding workstations, artificial intelligence (AI), deep learning, and data analytics applications. Equipped with 16 8-Channel DDR5 RDIMM memory slots, support for the latest PCIe 5.0 protocol through 6 x16 slots, 2 M.2 NVMe PCIe Gen4 x4 ports, dual 1GbE LAN networking, and the Intel® C741 chipset, the MS73-HB1 guarantees uninterrupted stability and outstanding energy efficiency. In addition, it offers comprehensive remote management capabilities through the GIGABYTE Management Console and GSM software, as well as advanced TPM 2.0 hardware security.

Support for Dual Intel® Xeon® Scalable 4th & 5th Generation Processors

Unlock ultimate computing power in your enterprise environment thanks to support for dual Intel® Xeon® Scalable 4th and 5th Gen processors (as well as the Intel® Xeon® CPU Max series) with LGA4677 socket. The Gigabyte MS73-HB1 motherboard leverages Intel's revolutionary architecture, offering up to 64 cores per processor, enabling the simultaneous execution of complex tasks with unmatched speed. The integrated AI acceleration engines and Intel's specialized accelerators dramatically optimize performance in artificial intelligence, deep learning, networking, and data analytics applications, delivering best-in-class performance per Watt.

8-Channel DDR5 RDIMM Memory Architecture with 16 Slots

Manage massive volumes of data without the slightest sign of lag thanks to the advanced memory architecture of the Gigabyte MS73-HB1. It features 16 DIMM slots with support for eight-channel memory (8-Channel DDR5 RDIMM), delivering a dramatic increase in overall bandwidth and memory operating frequency compared to older DDR4 generations. This enormous capacity and lightning-fast data throughput make this motherboard the ideal choice for demanding virtualization environments, high-load databases, and high-density computing tasks.

Full Support for PCIe 5.0 & Expanded Expansion Slots

The motherboard offers the market’s maximum I/O throughput by fully leveraging the PCIe 5.0 protocol, which doubles bandwidth compared to the previous generation, reaching 128GB/s. It is equipped with 6 PCIe Gen5 x16 expansion slots, allowing the installation of multiple high-end GPU accelerators, high-speed networking cards, and storage controllers. In addition, support for the CXL 1.1 protocol dramatically improves performance through memory coherence and direct access by accelerators to system memory.

Flexible PCIe Gen4 M.2 & SlimSAS Storage Options

Meet every modern data storage need with the rich connectivity options integrated by the Intel® C741 chipset. The Gigabyte MS73-HB1 features 2 M.2 NVMe slots with PCIe Gen4 x4 interface for lightning-fast operating system drives, 3 SlimSAS 4i connectors with SATA interface, as well as 2 standard 7-pin SATA ports. This architecture enables easy integration of ultra-fast NVMe SSDs and SAS/SATA storage arrays, ensuring immediate access and data security for your business.

GIGABYTE Management Console & GSM Complete Management Suite

Simplify the management and maintenance of your infrastructure with Gigabyte’s free professional tools. The preinstalled GIGABYTE Management Console platform provides remote real-time monitoring of system health through an intuitive web browser interface, supporting the IPMI standard and automatic event logging. At the same time, the GIGABYTE Server Management (GSM) suite enables simultaneous management of entire server clusters through GSM Server, CLI, Agent, Mobile app (Android/iOS), and a dedicated Plugin for VMware vCenter.

Advanced Hardware Security TPM 2.0 & Enterprise Reliability

Protect your sensitive corporate data from unauthorized access with advanced security technologies. The motherboard supports optional TPM 2.0 module (Serial Peripheral Interface or LPC bus) for hardware-based authentication and secure storage of passwords, encryption keys, and digital certificates. At the same time, Intel® TDX technology provides enhanced confidentiality at the virtual machine (VM) level. Designed with strict thermal engineering standards and energy efficiency, the MS73-HB1 guarantees uninterrupted operation (Continuous Operation) without unplanned interruptions.
