How to Fix: memtest86+ error explosion, and then nothing

Technical issue with memtest86+ error explosion and system instability, resolved by swapping RAM sticks.

Quick Answer: Swap RAM sticks to resolve memory-related issues.

The user's desktop has become less stable over the last two weeks, experiencing frequent BSODs (memory-related error messages), difficulties with application installs/uninstalls, random application misbehavior, and occasional driver loading issues. Memtest86+ was used to diagnose the issue, revealing thousands of errors in 4 passes.

The user is frustrated by the intermittent nature of these problems and seeks a solution to resolve the memory-related issues.

🔍 Why This Happens

  • The primary cause of this error is likely due to faulty RAM modules. The memtest86+ results indicate that thousands of errors were found in 4 passes, suggesting a significant issue with the system's memory. This could be caused by defective or incompatible RAM modules, which are not recognized by the system.
  • An alternative reason for this error could be related to the motherboard or other components on the system, however, memtest86+ results suggest that the RAM is the main culprit.

🚀 How to Resolve This Issue

Rotating and Testing Individual RAM Sticks

  1. Step 1: Boot into the system with one stick of memory installed in a single slot (e.g. slot 1). Run memtest86+ for at least two passes to ensure that no errors are found.
  2. Step 2: If no errors are reported, move on to the next stick and repeat the process (steps 1-2) until all sticks have been tested individually.
  3. Step 3: Once all individual sticks have been tested, try swapping them out in different combinations to identify any potential issues with specific RAM modules or slots.

Re-testing the System with All RAM Sticks

  1. Step 1: Boot into the system with all four sticks of memory installed in their respective slots. Run memtest86+ for an extended period (at least several hours) to ensure that no new errors are found.
  2. Step 2: Monitor the system's behavior and performance during this test, as some systems may exhibit issues before the actual error messages appear.

🎯 Final Words

Based on the user's experience with memtest86+, it is likely that faulty RAM modules are the primary cause of the system's instability. By rotating and testing individual RAM sticks and re-testing the system with all RAM sticks, the user can identify and potentially replace any defective modules to resolve the issue. If no issues are found during these tests, other components on the system may be causing the problem.
