amdkmdap Stopped Responding
What is this error?
AMD's display driver (amdkmdap or atikmpag.sys) stopped responding and was recovered by Windows. This is the AMD-specific TDR crash.
Common causes
- AMD Adrenalin driver bug
- GPU overheating
- unstable overclock or undervolt
- AMD driver timeout settings
- VRAM issues
How to fix it
- DDU clean install of AMD driver
- disable AMD ULPS
- check GPU temps
- reset Adrenalin settings

"amdkmdap stopped responding" or "atikmpag stopped responding" means AMD's display driver crashed and Windows recovered it. Both driver names refer to AMD GPU drivers — amdkmdap is newer, atikmpag is the legacy name.
Affects all AMD Radeon GPUs — RX 500-series through RX 9000-series.
How to fix it:
- Clean install AMD driver — download DDU, boot into Safe Mode, completely remove AMD drivers, then install the latest AMD Adrenalin driver. Or use AMD's own 'Factory Reset' option during installation
- Disable AMD ULPS (Ultra Low Power State): in Registry Editor, search for 'EnableULPS' and set all instances to 0 — ULPS can cause the GPU to not wake up properly
- In AMD Adrenalin, reset all settings to 'Default' — especially any tuning/overclocking profiles
- Disable AMD Radeon Anti-Lag, Radeon Boost, and Enhanced Sync — these features can cause driver instability
- Check GPU temps — AMD GPUs throttle at 90-110C junction temperature depending on model
- Increase TDR timeout in Registry Editor: HKLM\SYSTEM\CurrentControlSet\Control\GraphicsDrivers > DWORD 'TdrDelay' = 10
- If using a 5700 XT or 6000-series, try disabling hardware acceleration in Discord and Chrome — these GPUs are notorious for TDR with hardware-accelerated apps
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
