What is AVX-PANIC?
Crash when executing AVX instructions is a high-severity processor (CPU) issue. Calculation error when using AVX/AVX2 wide vector instructions. Typical causes include dried thermal paste, overclocking too aggressively, silicon degradation and weak power supply. Use the steps below to track down and fix the cause.
Common Causes
- Dried thermal paste
- Overclocking too aggressively
- Silicon degradation
- Weak power supply
Step-by-Step Fix Guide
-
1
Improve cooling and repast
Start with Improve cooling and repast — it clears the most frequent root cause behind AVX-PANIC in the majority of cases we've seen.
-
2
Increase LLC (Load-Line Calibration) in BIOS
For cases that don't clear up right away, the remaining steps target less typical cpu instability problems.
-
3
Undervolting
Still seeing AVX-PANIC after that? "Undervolting" is the next thing to check.

Frequently Asked Questions
Dried thermal paste accounts for the majority of AVX-PANIC reports; overclocking too aggressively, silicon degradation and weak power supply come up less often but are documented.
Most AVX-PANIC reports resolve after "Improve cooling and repast". The rest of the guide above is there for the cases that don't.
Rated high severity — AVX-PANIC isn't immediately destructive, but recurring instances are a sign to fix it sooner rather than later.
You shouldn't need to. Work through the guide above first — a reinstall is only worth considering if none of those steps help.
Not necessarily. AVX-PANIC can be triggered by software and driver issues, overclocking instability, or BIOS misconfigurations — not just hardware failure. Run through the diagnostic steps above before concluding the processor itself is defective.
