Server barebone ASRock 1U2N2G-AM5/2T — LGA 1718, DDR5 up to 48GB, 10Gb Ethernet, Aspeed AST2600, 1600W PSU

ASRock 1U2N2G-AM5/2T is a 1U rack server barebone designed for dense, space-efficient deployments. It uses an LGA 1718 single-socket AM5 platform compatible with EPYC™ 4005/4004 and Ryzen™ 9000/8000/7000 series processors and accepts up to four DDR5 UDIMMs (ECC or non‑ECC) for a maximum supported memory of 48 GB. Each of the two nodes includes a full‑height PCIe 5.0 x16 slot, a PCIe 4.0 x4 M.2 slot, onboard Aspeed AST2600 graphics and dual 10 Gigabit Ethernet ports by Broadcom. The system provides UEFI AMI BIOS, IPMI remote management and two front USB 2.0 ports, and comes with a redundant 1600 W CRPS power supply suited to 1U rack environments.

Advantages

The barebone balances compact 1U density with dual independent nodes, enabling two separate compute instances in a single chassis while preserving full‑height PCIe slot connectivity. Integrated Broadcom 10GbE per node and onboard Aspeed AST2600 allow immediate network and management access without additional adapters. UEFI AMI BIOS and IPMI support simplify remote provisioning and monitoring, and the included 1600 W 1+1 power solution addresses reliability and high-power compute loads in rack installations.

Suitable for

• Edge computing and small data centre racks where space is limited
• Network appliances, virtual network functions (VNFs) and firewall/router platforms
• High‑density hosting for lightweight multi‑tenant or containerized workloads
• Remote management and monitoring platforms requiring IPMI and Aspeed remote graphics

Key specifications

• Form factor: 1U rack chassis with two independent nodes
• CPU socket: LGA 1718 (single socket AM5 per node), supports specified EPYC and Ryzen series processors
• Memory: 4 DDR5 UDIMM slots per node (2DPC), ECC and non‑ECC supported, maximum combined memory up to 48 GB using 288‑pin DIMMs
• Expansion: 1 full‑height dual‑slot PCIe 5.0 x16 slot per node
• Storage: 1 M.2 slot (PCIe 4.0 x4) per node for NVMe storage
• Networking: Dual 10Gb Ethernet (Broadcom BCM57416) per node via RJ‑45
• Management and graphics: Onboard Aspeed AST2600 BMC with IPMI remote management
• BIOS: UEFI AMI BIOS, 256 Mbit
• Front I/O: Two USB 2.0 ports
• Power: 1600 W 1+1 CRPS redundant power supply suitable for 1U operation

How to use

Install the appropriate AM5 CPU into the LGA 1718 socket on each node following standard server CPU handling procedures, populate DDR5 UDIMMs into the four DIMM slots per node according to the board’s population guidelines, and install NVMe drives into the M.2 slots if required. Connect network cables to the RJ‑45 10GbE ports and configure BIOS/UEFI settings as needed. Use IPMI through the BMC (Aspeed AST2600) for out‑of‑band management, remote console access and firmware updates. Ensure the chassis is mounted in a compatible 1U rack position and the redundant 1600 W power supply is connected to a suitable power source or PDU.

Recommendations

Use ECC DDR5 modules when workload integrity and error mitigation are important; verify supported memory speed and capacity with your chosen processor. For thermal and acoustic stability in 1U deployment, ensure adequate rack airflow and avoid exceeding recommended TDP for installed CPUs. Keep UEFI and BMC firmware up to date and configure IPMI access controls for secure remote management.
