Model specifications

Architecture / generationSkylake-W, Xeon W-2100 workstation generation (2017)
Exact partIntel Xeon W-2123
Package / socketFC-LGA2066 (LGA2066 / Socket R4)
Compute and clocks4 cores / 8 threads; 3.60 GHz base; up to 3.90 GHz Intel Turbo Boost 2.0
Cache / power8.25 MB Intel Smart Cache; 120 W TDP
Memory4-channel DDR4-2666; ECC support; up to 512 GB maximum (board and DIMM type dependent)
Expansion48 PCI Express 3.0 lanes from CPU
Board compatibilitySingle-socket C422/LGA2066 workstation board validated for Xeon W-2100, such as Supermicro X11SRA-F; check exact CPU support, board revision and BIOS before purchase. Not interchangeable with the later W-2200 by socket alone.

Compatibility and service

  • Use an LGA2066 C422 workstation board with explicit Xeon W-2123 support and the required BIOS; chipset/socket match alone is insufficient.
  • Populate four memory channels with board-qualified DDR4-2666 ECC UDIMMs or other specifically validated memory; capacity is platform dependent.
  • Provide cooling and power delivery rated for the 120 W processor and verify cooler clearance/mounting.
  • No integrated graphics; provide a discrete GPU or other display adapter.
