Compatibility and service
- Require board-manufacturer confirmation for W-2255; earlier Xeon W-2100 support does not automatically mean W-2200 support.
- Use quad-channel DDR4-2933 ECC memory listed by the board QVL; memory capacity and DIMM type depend on board population rules.
- Size cooling and board power delivery for the 165 W TDP and sustained workloads.
- No integrated graphics; a separate graphics adapter is needed for display.
