Motherboard ASRock ROME2D16-2T LGA 4094 EEB, dual-socket, 16 DIMM DDR4, 3.2 TB RDIMM, 5x PCIe x16 Gen4, 16x SATA III

ASRock ROME2D16-2T is an EEB server motherboard designed for dual-socket AMD EPYC 7003 processors (LGA 4094). It supports up to two CPUs, 16 DDR4 DIMM slots with a maximum RDIMM capacity of 3.2 TB at 3200 MT/s, five PCIe x16 Gen4 slots, two M.2 connectors and 16 SATA III ports. Onboard components include AST2500 graphics, three RJ-45 Ethernet ports with a Realtek RTL8211E controller, multiple fan and power connectors, a TPM header and AMI BIOS with SMBIOS 3.3.0 and ACPI 6.3. The board is intended for rack or workstation server use in dry, ventilated environments and fits EEB chassis dimensions of approximately 305 × 330 mm.

Advantages

This motherboard supports high-density memory configurations up to 3.2 TB RDIMM across 16 DIMM slots and dual AMD EPYC 7003 processors for scalable compute. Five PCIe x16 Gen4 slots and two M.2 interfaces provide flexible expansion for accelerators and NVMe storage, while 16 SATA III ports enable large-capacity HDD/SSD arrays. Integrated AST2500 management graphics, multiple fan connectors and a TPM header simplify server integration and maintenance in controlled environments.

Suitable for

• High-memory database servers
• Virtualization hosts and hyperconverged infrastructure
• Compute-dense workstation or rack servers with PCIe accelerators
• Storage servers using multiple SATA III drives and NVMe M.2 devices

How to use

Install the motherboard into a compatible EEB chassis and connect dual AMD EPYC 7003 processors into the LGA 4094 sockets according to the CPU and heatsink manufacturer instructions. Populate memory modules in matched DIMM slots for optimal channel operation, and attach storage devices to SATA III ports or M.2 slots as required. Connect power via the 24-pin ATX connector and required CPU power inputs, attach system fans to the provided headers, and connect LAN, VGA and USB peripherals to the rear I/O. Configure BIOS settings using the AMI interface and verify SMBIOS/ACPI settings for your server operating system.

Use this motherboard only in a dry, well-ventilated environment and ensure adequate airflow and cooling when populating multiple CPUs, high-density memory and expansion cards.
