Compatibility and service
- Confirm exact Xeon W-2155 support and BIOS revision for the board; a generic LGA2066 listing is not enough.
- Use board-qualified quad-channel DDR4-2666 ECC memory and follow its DIMM population rules.
- Provide cooling and VRM airflow suitable for the 140 W thermal design power.
- This CPU has no integrated graphics; a discrete graphics solution is required for display output.
