AsRock WC422D8A-2T/U ATX Server Motherboard
The AsRock WC422D8A-2T/U is a single-socket LGA 2066 ATX server motherboard built for rack-mount workstation and server chassis where dual 10GbE networking needs to be on-board rather than added via an expansion card. Model WC422D8A-2T/U ships at 3.97 lb and measures 13.78 x 11.65 x 2.76 in, dimensions worth checking against your chassis standoffs and rear I/O shroud before ordering.
Overview
This board targets integrators building single-CPU Intel Xeon W or Core X-series platforms (Socket R4 / LGA 2066) into rack servers, video management workstations, or industrial compute nodes. The "2T" in the WC422D8A-2T/U designation points to its dual 10GbE LAN configuration, a detail that matters if your deployment plan calls for direct-attached storage networking or link aggregation without burning a PCIe slot on a NIC.
Key Features
- Single Socket R4 (LGA 2066): supports Intel's high-core-count workstation/server-class CPUs for this socket generation, giving you a upgrade path within the same platform generation instead of a full board swap.
- ATX form factor: fits standard ATX-compatible rack and tower server chassis, simplifying sourcing for replacement chassis or spares versus proprietary board sizes.
- Dual 10GbE onboard LAN: frees a PCIe slot that would otherwise go to a network card, useful when you also need room for a capture card, RAID controller, or GPU in the same 2.76 in board height envelope.
- Compact 13.78 x 11.65 in ATX footprint: confirm clearance against your rack chassis motherboard tray before ordering, particularly around rear I/O and PCIe riser placement.
Integration & Compatibility
Pair this board with a chassis and cooling solution rated for LGA 2066 socket CPUs, and verify memory and expansion card compatibility against AsRock's published support list for this exact model before finalizing a build. Country of origin is listed as CN for import/compliance documentation purposes.
Frequently Asked Questions
Q: What socket does the WC422D8A-2T/U use?
A: Single Socket R4 (LGA 2066).
Q: What form factor is the WC422D8A-2T/U?
A: Standard ATX.
Q: Does the WC422D8A-2T/U include onboard networking?
A: Yes, dual 10GbE LAN ports are integrated on the board.
Q: How much does the WC422D8A-2T/U weigh, and what are its dimensions?
A: 3.97 lb, measuring 13.78 x 11.65 x 2.76 in (L x W x H).
The WC422D8A-2T/U crosses my bench when someone's building a rack node that needs dual 10GbE without eating a PCIe slot for a NIC. That's the whole story this board tells at the spec level available to me right now.
Technical Highlights:
- Single Socket R4 (LGA 2066): puts this in workstation/server CPU territory rather than mainstream desktop sockets — plan cooling and power delivery accordingly.
- Dual 10GbE onboard: two network ports built into the board means one less expansion slot committed to networking hardware in your chassis.
- 13.78 x 11.65 x 2.76 in ATX footprint at 3.97 lb: standard ATX mounting, so chassis sourcing stays flexible — measure your PCIe riser clearance against the 2.76 in height before committing to a 1U or 2U build.
Deployment Considerations:
- Confirm CPU, memory, and expansion card compatibility against AsRock's official support list for the WC422D8A-2T/U before finalizing a parts order — I don't have that detailed compatibility matrix in front of me for this listing.
- Country of origin is CN — factor that into any import/compliance paperwork for government or regulated deployments.
This is the board I'd spec for a single-CPU LGA 2066 rack server build where dual 10GbE needs to be native to the board rather than an add-in card — common in dense recording or storage-node builds where slot real estate is tight.
