Best single-socket Intel Xeon workstation motherboards
Researched by Deal.ai's shopping agent across stores on November 3, 2026. Prices below are today's.
Top pick: Supermicro X11SRA. It's the cleanest fit for a single-socket Xeon workstation: LGA2066 with the Intel C422 chipset, which is the Xeon-W pairing that takes DDR4 ECC RDIMMs, in a standard ATX layout that drops into a normal case. If you want one board to build around and keep for years, this is it.
Who the others suit:
- Dell 026G78 (PowerEdge T130 board) — for a cheap, proven LGA1151 Xeon E3 build with DDR4; it's a server board, so check its I/O and mounting before committing.
- ASRock EPC621D8A — for a bigger LGA3647 Xeon Scalable build with DDR4 ECC; the listing I found is open box.
- Gigabyte MW83-RP0 / MW53-HP0 — newer workstation boards, but they're DDR5 platforms, so they don't meet the DDR4 requirement.
- ASRock Rack EC266D4U-2L2T — single socket and compact micro-ATX, but DDR5 only.
One caveat: the spec sheets I could pull don't spell out ECC support for every board, so confirm the exact revision's memory QVL before buying.
