What is PROCHOT-1?
Thermal throttling of CPU performance is a high-severity processor (CPU) issue. The processor slows down to avoid overheating and damage. Typical causes include dried thermal paste, overclocking too aggressively, silicon degradation and weak power supply. Follow the steps below to fix it.
Common Causes
- Dried thermal paste
- Overclocking too aggressively
- Silicon degradation
- Weak power supply
Step-by-Step Fix Guide
-
1
Improve cooling and repast
As a first move, Improve cooling and repast handles the most common scenario behind PROCHOT-1.
-
2
Increase LLC (Load-Line Calibration) in BIOS
A recurrence usually points to a rarer cpu instability cause, which is what the following steps are meant to catch.

3
Undervolting
Still seeing PROCHOT-1 after that? "Undervolting" is the next thing to check.

Frequently Asked Questions
PROCHOT-1 is most often triggered by dried thermal paste. Other reports point to overclocking too aggressively, silicon degradation and weak power supply as contributing factors.
Most PROCHOT-1 reports resolve after "Improve cooling and repast". The rest of the guide above is there for the cases that don't.
Rated high severity — PROCHOT-1 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. PROCHOT-1 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.
