Compatibility and revision notes
The published board CPU power envelope matters: do not install an unsupported high-TDP AM3+ processor based solely on socket fit. Confirm MSI’s model-specific CPU list and BIOS version.
Before installation, check the manufacturer’s model-specific CPU support table and manual. Verify the power supply, cooler, chassis clearance, memory population rules and any shared PCIe or SATA lanes for the intended configuration.
Preservation and repair
Inspect the VRM heatsink and socket before testing power-hungry CPUs. Keep the manual’s memory population order and document BIOS settings before firmware service.
For an archive record, photograph PCB labels before cleaning and note serial/date codes, firmware, accessories, known faults, repairs and test conditions. Use ESD-safe handling; do not energize a board with loose conductive hardware beneath it.
