ASRock Rack TURIND8X-2T/500W AMD EPYC 9004 & 9005 Series Motherboard

TURIND8X-2T/500W SP5 Platform

The TURIND8X-2T/500W is a single-socket SP5 server motherboard from ASRock Rack, built in an EEB 320.8 x 330.2 form factor for high-expansion, accelerator-heavy systems. It targets deployments that prioritise PCIe slot density and bandwidth over multi-socket scaling, while retaining full server-class management and monitoring. The platform is defined by its high TDP CPU support, extensive PCIe Gen5 slot layout, mixed MCIO and M.2 storage connectivity, and integrated 10GbE networking.

Ready for AMD EPYC 9005 & 9004 Series Workstation Processors

The board supports a single Socket SP5 (LGA 6096) processor, compatible with AMD EPYC 9005, 9004 (including models with AMD 3D V-Cache), and 97x4 series processors. It is rated for processor thermal design power up to 500 W, enabling high-core-count and high-frequency EPYC configurations in a single-socket footprint. As with other SP5 platforms, the design uses AMD EPYC’s System-on-Chip architecture, consolidating memory, PCIe, and storage controllers directly on the CPU without a separate chipset.

1DPC 6400 MHz DDR5 RDIMM Across 8 Channels

The motherboard provides eight DDR5 DIMM slots arranged in a 1DPC topology to maintain signal integrity and predictable memory bandwidth. It supports DDR5 288-pin RDIMM and RDIMM-3DS modules. Maximum supported capacity per DIMM reaches 128 GB for standard RDIMMs and up to 256 GB for RDIMM-3DS modules. Memory speeds are supported up to 6400 MHz at 1.1 V, aligning with current-generation EPYC memory specifications.

PCIe 5.0 Expansion and Lane Sharing

A defining characteristic of the TURIND8X-2T/500W is its dense PCIe slot layout. The board provides seven full-length PCIe 5.0 x16 slots and one PCIe 5.0 x8 slot, with multiple slots supporting CXL capability depending on the installed processor generation. Several slots share PCIe lanes with onboard MCIO and M.2 connectors. Certain slots automatically reduce to x8 or x4 operation when shared devices are populated, with lane routing managed through automatic switching and jumper configuration. This allows flexible trade-offs between slot bandwidth and onboard expansion depending on system requirements.

MCIO, M.2 and Storage Connectivity

In addition to full-length PCIe slots, the board includes multiple MCIO connectors supporting PCIe 5.0 x4 operation, with selected connectors configurable as four SATA 6 Gb/s lanes. MCIO connectivity shares PCIe resources with specific PCIe slots and the PCIe x8 slot, introducing configurable behaviour depending on which interfaces are populated. Two M.2 M-key slots are provided, supporting PCIe 5.0 x4 operation, with one slot additionally supporting SATA 6 Gb/s. Both M.2 slots support 22110 and 2280 form factors. Using the EPYC CPU’s integrated storage controllers, the platform supports up to 16 SATA 6 Gb/s connections, exposed through MCIO and optional M.2-based expansion.

Networking, Management and I/O

Onboard networking is delivered via a Broadcom BCM57416 controller providing two 10GbE RJ45 ports for high-throughput system connectivity. A dedicated management LAN is provided through a Realtek RTL8211F PHY connected to the onboard BMC - ASPEED AST2600 - which enanles IPMI-based remote management, sensor monitoring, and remote KVM access. The same controller provides VGA output for local console access.

Rear I/O and Internal Connectivity

Rear I/O includes a VGA port, a DB9 serial port, two USB 3.2 Gen1 Type-A ports, dual 10GbE RJ45 ports, and a dedicated IPMI management port, alongside a UID button with LED. Internally, the board offers extensive headers for chassis integration, including system and auxiliary panel headers, fan headers, thermal sensor input, TPM (SPI), SMBus, PMBus, IPMB, USB 3.2 Gen1 header, and NMI support. Power delivery is handled via a 24-pin ATX connector and three 8-pin ATX 12V connectors.

Management, Monitoring and Diagnostics

The platform uses an AMI UEFI BIOS stored in a 256 Mb (32 MB) SPI flash ROM, supporting ACPI 6.4 compliance and SMBIOS 3.5 or later. Hardware monitoring covers CPU, motherboard, and thermal sensor inputs, along with detailed voltage rail reporting and multi-zone fan speed control. Diagnostic features include a standby power LED, 80-port debug LED, eight fan-fail LEDs, and a BMC heartbeat LED, supporting rapid fault identification during deployment and servicing.
