Product Overview

AMD EPYC™: The New x86 Option

AMD’s return to the CPU segment delivers a whole new value proposition to the x86 world. Built on GIGABYTE’s extensive design expertise across a range of chipset platforms, this AMD EPYC™ platform is already receiving acclaim for its high specification:

• Memory.
• I/O.
• Network Connectivity.

This platform is intended as an alternative for builders in the x86 space and packs a real punch in flexibility and expansion options.

EPYC 7000 Series CPU Key Features:
• 32 Cores Compute.
• 8 Channels Memory.
• 128 PCIe Lanes
• Regulated Per Core Power.
• Integrated Custom Security.

Comprehensive I/O

Both single and dual-socket CPUs come equipped with 128x PCIe lanes, providing extensive I/O options. This is a huge improvement in I/O vs. incumbent x86 offerings.

Increased I/O allows for flexibility in extending your storage, networking or compute to a level previously unattainable with standard server motherboards.

In addition, the integrated nature of the processor – designed as a system-on-chip (SoC) - means that there is no need for a separate PCH and less additional switches needed for expansion lanes.

High-Speed Networking

GIGABYTE offers 10Gb across dual ports on-board, ensuring that users can get the most out of their system and are well equipped for today’s traffic demands. The server’s network performance is boosted with full-line rate throughput and CPU overhead is reduced, leaving the EPYC to focus on the real compute tasks.

Dense, High Speed Storage Support: On-Board M.2

GIGABYTE AMD EPYC™ platforms are designed to support on-board ‘M.2’ storage devices for time-sensitive operations and leaves room on the standard storage for compute tasks. Delivering up to 32 Gb/s data transfer speeds, M.2 offers users considerably faster storage performance than current mSATA devices.

Data Security: TPM 2.0 Module Support*

GIGABYTE’s EPYC™ platform is designed to support Trusted Platform Modules (TPM - discrete cryptographic on-board processors).
*TPM 2.0 Module not included, available separately - GIGABYTE P/N: 9CTM000NR-00.

Carefully Selected Components

GIGABYTE’s passive components are meticulously selected to guarantee a super stable operating environment and allow the processors and the memory to deliver their maximum performance. GIGABYTE’s server motherboards are built with ultra-long lasting components for the highest reliability attainable which allows us to offer some of the most durable servers in the industry.

Radeon Instinct™ MI25 Support*

GIGABYTE’s EPYC server platform is fully compatible with AMD’s new Radeon Instinct™ MI25, one of the world’s fastest training accelerators. The MI25 can deliver up to 24.6 TFLOPS of FP16 and 12.3 TFLOPS of FP32 peak performance, and features large BAR (Base Address Register) support for multi-GPU peer-to-peer communication. Combining AMD’s CPU and GPU solutions together with its ROCm open software platform allows for enhanced synergy and optimisation, delivering a powerful compute solution with lower latency to meet the challenges of HPC.
*For use in slot 3 (counting from the nearest board edge) only.

GIGABYTE Server Management (GSM)

GIGABYTE SERVER include the exclusive ‘GIGABYTE Server Management’ utility designed to provide datacenter and rack-level management via an effortless user experience. The browser-based client (or CLI if preferred) enables administrators to remotely manage and monitor the GSM Server and GSM Agent modules. This reduces administrative burden further increasing ROI. Additionally, the API programmable client enables administrators to streamline and automate workflows with multiple concurrent sessions for the highest degree of efficiency. All modules are fully IPMI and Redfish compliant.

GIGABYTE BMC Interface: Easy BIOS Upgrade

GIGABYTE has developed this integrated function (requiring no additional software) that allows users to update the BIOS of motherboards through the BMC controller:

• No need to install core components such as CPUs, memory, drives and OS.
• No need to power on the system (NB. PSU must be connected).
• Update individual (IPMI 2.0) or multiple boards simultaneously (Command Line).

Environmental Compliance

GIGABYTE maintains its commitment to green products, and adheres to the latest RoHS regulations (in effect July 2017).

• AMD EPYC™ 7000 series processor family.
• 8-Channel RDIMM/LRDIMM DDR4, 16x DIMMs.
• 2x SFP+ 10Gb/s LAN ports (Broadcom® BCM 57810S).
• 1x Dedicated management port.
• 4x SlimSAS (for 16 x SATA 6Gb/s) ports.
• Ultra-Fast M.2 with PCIe Gen3 x4 interface.
• Up to 4x PCIe Gen3 x16 slots and 3x PCIe Gen3 x8 slots.
• Aspeed® AST2500 remote management controller.

Please Note: Memory runs at 2133MHz when 1R/2R memory modules are fully populated.
