Compatibility and service notes
- Requires an LGA1200 board with exact model and BIOS support. 500-series boards are the native platform generation; selected 400-series boards support some 11th-generation CPUs only with appropriate BIOS and board-specific validation. Verify the CPU support list rather than inferring compatibility from the socket alone. This locked 65 W SKU has less peak power than higher-power models, but cooling and board power policy still matter.
- The i5-11400 includes UHD Graphics 730; the i5-11400F is a separate no-iGPU product. This non-K model has a locked multiplier.
- Before installation, compare the full processor marking with the motherboard maker’s support list and minimum BIOS, then confirm cooler mounting, memory type, power delivery, and firmware settings. Socket fit alone does not establish compatibility; never force the package.
Service & archival record
Record the full model/ordering code and S-spec, stepping, board revision, BIOS/microcode, memory configuration, cooler, power profile, physical condition, provenance, and source revision. Separate measured behavior from published specifications.
Handle the package by its edges and protect socket contacts. Inspect for contamination, damaged pads/pins, and uneven cooler pressure before use.
