ASRock Rack B650D4U-2L2T/BCM Server Motherboard

The ASRock Rack B650D4U-2L2T/BCM is a professional-grade Micro ATX server motherboard designed for AMD Ryzen 7000 series processors. Built on the AMD B650E chipset with AM5 socket (LGA 1718), this board delivers enterprise-level performance and reliability for workstation and server applications supporting processors up to 170W with proper cooling.

Memory and Storage

Equipped with 4 DDR5 DIMM slots supporting both ECC and non-ECC UDIMM configurations, the board handles up to 96GB of memory at speeds reaching 5200MHz (1DPC) or 3600MHz (2DPC) in dual-channel mode. Storage flexibility includes 4 SATA 6Gb/s ports and one M.2 slot with PCIe 5.0 x4 interface supporting 2280/2242 form factors.

Network Connectivity

Network performance is exceptional with quad LAN configuration: dual 10GbE RJ45 ports powered by Broadcom BCM57416 controllers and dual 1GbE RJ45 ports using Intel i210 controllers. This configuration ensures high-bandwidth data transfer and network redundancy for mission-critical applications.

Expansion and Graphics

The expansion capabilities include three PCIe slots: one PCIe 5.0 x16 slot, one PCIe 5.0 x4 slot, and one PCIe 4.0 x1 slot. Display outputs feature one HDMI port and one DisplayPort for AMD processors with integrated graphics, plus VGA output through the ASPEED AST2600 BMC controller.

Remote Management

IPMI remote management functionality through the dedicated RJ45 port allows administrators to monitor and control the system remotely. The BMC provides comprehensive hardware monitoring including CPU, DDR, motherboard, chipset, 10G LAN, and M.2 slot temperatures, plus multi-speed fan control and extensive voltage monitoring across 16 different rails.

System Features

The motherboard includes AMI UEFI BIOS with 256Mb SPI Flash ROM, ACPI 6.4 compliance, and SMBIOS 3.5 support. Back panel I/O provides 4 USB 3.2 Gen1 Type-A ports, serial port, UID button with LED, and dedicated IPMI port. Internal connectivity includes multiple fan headers, TPM support, SMBus, PMBus, and IPMB headers for comprehensive system integration.

Operating Environment

Designed for reliable operation in temperatures ranging from 10°C to 35°C, with non-operating tolerance from -40°C to 70°C. The board is backed by a 3-year warranty, ensuring long-term reliability for server and workstation deployments.
