Integrated Memory Controller (IMC) failure

What is IMC-FAULT-00?

This high-severity issue affects the processor (CPU). The controller inside the processor cannot communicate stably with the RAM. Reports of Integrated Memory Controller (IMC) failure usually describe a sudden crash, brief unresponsiveness, or a stop-code screen appearing out of nowhere. It's most often caused by 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 IMC-FAULT-00 for most affected systems.

• 2
  Increase LLC (Load-Line Calibration) in BIOS

  If the fault persists, continue with the next steps, which account for less common cpu instability causes.

• 3
  Undervolting

  Still seeing IMC-FAULT-00 after that? "Undervolting" is the next thing to check.
