Memory errors on x86_64 (x64) systems running Linux or Windows will give rise to Machine Check Exceptions (MCE). This document will tell you how to analyze these MCEs using HERD.
- Silent Northbridge MCE
- Performance Reduction
- Memory Capacity Reduction
This document describes which troubleshooting steps to take when trying to resolve memory errors on x64 systems running the Linux and Windows operating systems. A memory error will give rise to a machine check exception (MCE).
In the case of correctable memory errors, the MCE will be reported on the console and in the system log files /var/log/messages on Linux and the Event Log on Windows.
In the case of an uncorrectable memory error, the platform will reset, and a MCE entry may appear in the system log file /var/log/messages after a reboot occurs.
The presence of this log entry is not always guaranteed as the severity of the platform crash dictates the platforms ability to report errors.
