| Firmware compatibility | Use the exact model and board revision support page. Check CPU support and minimum BIOS before fitting a processor; do not flash firmware intended for a similarly named board. |
Compatibility and revision notes
Do not confuse the 990FX Extreme4 with the 970 or 990FX Extreme3 family. Check ASRock’s CPU list for the exact processor and BIOS; 140 W class CPUs require documented support and adequate cooling.
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
Check the AM3+ socket, chipset fan/heatsink, SATA headers and expansion-slot latches. Preserve RAID configuration and firmware identifier during maintenance.
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.
