What is SOCKET-PIN-FLT?
Bad contact in processor socket is a high-severity processor (CPU) issue. The pins in the processor socket do not touch, which causes accidental disconnection of the lines. 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
Improve cooling and repast is the first thing worth trying, since it resolves SOCKET-PIN-FLT for most affected systems.
-
2
Increase LLC (Load-Line Calibration) in BIOS
If the problem isn't fully resolved yet, the remaining steps rule out the less frequent cpu instability triggers.

3
Undervolting
Still seeing SOCKET-PIN-FLT after that? "Undervolting" is the next thing to check.

Frequently Asked Questions
SOCKET-PIN-FLT is most often triggered by dried thermal paste. Other reports point to overclocking too aggressively, silicon degradation and weak power supply as contributing factors.
"Improve cooling and repast" clears up most SOCKET-PIN-FLT reports by itself. The remaining steps above cover what's left.
Rated high severity — SOCKET-PIN-FLT 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. SOCKET-PIN-FLT 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.
