AMD WattMan Settings Reset / Crash
What is this error?
Default Radeon WattMan settings have been restored due to unexpected system failure. The GPU crashed and AMD's power management reset all tuning profiles.
Common causes
- unstable GPU overclock or undervolt
- aggressive WattMan power tuning profile
- driver instability during heavy GPU load
- VRAM overclock too high
- insufficient PSU power delivery
- thermal throttling triggering WattMan reset
How to fix it
- Reset WattMan to defaults
- disable auto-overclock features
- set a manual fan curve
- update AMD driver with factory reset

That WattMan popup after a crash or black screen is one of the most common AMD GPU issues. It hits hardest in demanding games like Cyberpunk 2077, Starfield, and Hogwarts Legacy where the GPU is running at full load.
How to fix it:
- Open AMD Software > Performance > Tuning and click 'Reset' to restore all defaults. Do not touch these settings again until the crashes stop
- If you were using Auto Overclock or Auto Undervolt, disable them completely. AMD's auto-tuning pushes clocks too aggressively on many cards
- Set a manual fan curve: Performance > Tuning > Fan Tuning. Aim for fans at 80% by 80C. Stock fan curves run too hot on many RX 7000/6000 cards
- DDU clean install: boot into Safe Mode, run Display Driver Uninstaller, restart, install the latest AMD driver with 'Factory Reset' checked
- If crashes continue at stock settings, your PSU may be the issue. RX 7900 XTX can spike 100W+ above its rated TDP — make sure your PSU has enough headroom
- Check Event Viewer > System for 'amdkmdap' errors to confirm it is a GPU driver crash
- As a temporary workaround, set Power Tuning to -5% to reduce power draw slightly
When to seek help
If this error keeps happening after trying the fixes above, it may point to a deeper hardware or system issue. Consider professional help if:
- The crash occurs across multiple games or applications
- You see the same error after a clean Windows install
- Your PC is less than a year old (could be a warranty issue)
- You smell burning or hear unusual sounds from your PC
