ECC RAM Error

What is RAM-ECC-ERROR?

ECC RAM Error ranks as a high-severity system memory (RAM) issue in our database. The ECC memory detected and corrected the error, but there is a risk of an uncorrectable error when retrying. Common triggers are aging of RAM modules, cosmic Rays, electrostatic discharges and unstable power supply. See the troubleshooting steps below for the fix.

Common Causes

• Aging of RAM modules
• Cosmic Rays
• Electrostatic discharges
• Unstable power supply

Step-by-Step Fix Guide

• 1
  Check ECC error logs

  We'd suggest Check ECC error logs first — it's the fix most often responsible for solving RAM-ECC-ERROR outright.

• 2
  Run the MemTest86 ECC test

  If the problem isn't fully resolved yet, the remaining steps rule out the less frequent ram instability triggers.

• 3
  Replace the faulty DIMM

  "Replace the faulty DIMM" covers a less common but documented cause of RAM-ECC-ERROR.

• 4
  Check the power supply to the server

  "Check the power supply to the server" is worth trying when unstable power supply turns out to be the culprit.
