Product information

Description

ASRock EPYC4000D4U (KNOLL3 X300) is a Micro-ATX server motherboard with Socket AM5 designed for AMD EPYC 4004/4005 and AMD Ryzen 7000/8000/9000 series processors. It accepts an ATX power supply or 12V DC-in and provides four DDR5 DIMM slots with support for ECC and non-ECC UDIMM modules up to a total of 48 GB. The board includes dual Gigabit Ethernet ports, integrated ASPEED AST2600 graphics/controller, remote management via IPMI, and multiple expansion and storage interfaces suitable for compact server or workstation builds.

Advantages

The micro-ATX form factor balances compact size and expandability, offering a PCIe 5.0 x16 slot and additional MCIO expansion options for high-speed devices. Dual LAN ports driven by Intel i210 provide reliable Gigabit connectivity while onboard IPMI (ASPEED AST2600) enables remote management and monitoring. DDR5 memory support with four DIMM slots allows for error-correcting ECC configurations on compatible modules, and two M.2 plus SATA III interfaces deliver flexible storage choices for both NVMe and SATA drives.

Suitable for

  • Compact rack or tower servers
  • Edge and industrial computing applications
  • Remote-managed appliances and network appliances
  • Small workstations requiring PCIe 5.0 expansion

Key specifications

  • Form factor: Micro-ATX (9.6" x 9.6")
  • Chipset: KNOLL3 X300
  • Processor socket: Socket AM5; compatible with AMD EPYC 4004/4005 and AMD Ryzen 7000/8000/9000 series
  • Memory: 4 DIMM slots (2DPC); DDR5 ECC/non-ECC UDIMM; maximum internal memory 48 GB
  • Expansion: 1 × PCIe 5.0 x16; MCIO slots supporting PCIe5.0 (x8 and dual x4 configurations)
  • Storage: 2 × M.2 (PCIe5.0 x4 capable) and 2 × SATA III (6 Gb/s)
  • LAN: 2 × RJ45 Gigabit Ethernet (Intel i210)
  • Video/Management: 1 × HDMI, 1 × DisplayPort; ASPEED AST2600 with IPMI remote management
  • BIOS: UEFI AMI (256 Mbit); ACPI version 6.4

How to use

Install the motherboard into a compatible Micro-ATX chassis and connect either a standard ATX power supply or a 12V DC input according to the board's power connector specification. Fit a supported Socket AM5 CPU and populate DDR5 UDIMM memory modules across the four DIMM slots following the motherboard manual for optimal dual-channel/2DPC population. Connect storage devices to the M.2 slots or SATA III ports and install any PCIe cards into the provided PCIe 5.0/MCIO slots. Configure network, storage, and firmware settings via UEFI BIOS and use IPMI for remote monitoring and management if required.

Usage recommendations

Use server-grade ECC DDR5 modules when fault tolerance is required; ensure BIOS is updated to the latest version before deploying in production. For stable network performance, use quality cables and configure the Intel i210 interfaces in the OS or management firmware as needed.
