ASRock Rack X470D4U
AM4/X470 ATX server-workstation board with ECC-capable UDIMM, dual GbE and IPMI. This record is restricted to the exact printed SKU; confirm the physical PCB revision before installation or firmware service.
MODEL / REVISION: X470D4U is the exact manufacturer model/SKU documented here. Match the PCB revision and assembly label printed on the physical board before choosing firmware or CPU support; revision-specific differences must not be inferred from a similar model or suffix.
Specifications
| Exact board / SKU | ASRock Rack X470D4U — exact product suffix retained; verify PCB revision from board silkscreen. |
|---|---|
| PCB revision | The manufacturer reference identifies this exact model SKU, not a single board assembly revision. Read the revision silk-screen on the physical PCB; no unverified revision number is assumed. |
| CPU socket / platform | One AMD Ryzen AM4 processor from the exact qualified CPU list; generation and BIOS floor depend on SKU. |
| Chipset / controller | AMD X470 |
| Form factor | ATX. |
| Memory / ECC | Four DDR4 UDIMM sockets; ECC UDIMM depends on supported CPU and validated memory. No RDIMM; check QVL. |
| PCIe topology | Two full-length PCIe 3.0 slots with lane width dependent on Ryzen CPU, plus chipset PCIe expansion; see manual map. |
| Storage | Eight SATA 6 Gb/s and two M.2 sockets with socket-specific SATA/PCIe modes and lane sharing. |
| Network / BMC | Dual Gigabit Ethernet; ASPEED AST2500 BMC with IPMI 2.0/KVM and dedicated management interface. |
| Firmware / platform support | Check X470D4U CPU list, minimum BIOS, QVL and BMC firmware. Do not confuse with X470D4U2/X470D4U-2T variants. |
Compatibility and revision notes
Check X470D4U CPU list, minimum BIOS, QVL and BMC firmware. Do not confuse with X470D4U2/X470D4U-2T variants. Populate memory only in the documented module class and channel order; ECC does not make UDIMM/RDIMM classes interchangeable. Check chassis clearance, cooler, power connectors, risers, storage cabling and BMC network isolation against the model manual.
Socket shape and chipset branding alone do not guarantee CPU compatibility. Confirm exact CPU/stepping, minimum BIOS, memory QVL, PCIe lane sharing and board revision before service.
Preservation and repair
Record PCB silk-screen, serial label, BIOS/BMC versions, MAC addresses, attached risers and cables, and test conditions. Use ESD-safe handling and the vendor socket procedure; never apply firmware for a visually similar SKU.
