Symptoms
- Random blue screens (BSOD) with different error codes each time
- Crashes happen more under heavy multitasking or gaming
- System becomes unstable after adding new RAM
- Errors mention memory-related messages like MEMORY_MANAGEMENT or IRQL_NOT_LESS_OR_EQUAL
Likely causes
- CommonA faulty RAM stickBad memory produces intermittent, hard-to-pin-down crashes.
- CommonRAM running at settings (speed or voltage via XMP/DOCP) it can't handle reliablyEnabling a RAM profile that's slightly unstable is a frequent cause.
- PossibleMismatched RAM sticks from different kitsMixing speeds or timings can cause instability even if the system boots.
- PossibleRAM not fully seatedA stick that's slightly loose can cause intermittent errors rather than a full failure to boot.
- PossibleAn unrelated driver or software issue misreported as memory-relatedNot all blue screens with memory-sounding names are actually caused by RAM.
What to do
- Run Windows Memory Diagnostic (search for it in the Start menu) and let it complete a full scan.
- For a more thorough test, run MemTest86 from a bootable USB drive overnight.
- If errors are found, test each RAM stick individually to identify which one is failing.
- If RAM was recently overclocked or an XMP/DOCP profile was enabled, reset to default (JEDEC) speeds and retest.
- Reseat all RAM sticks fully, ensuring they're in the motherboard's recommended slots.
- If testing shows no memory errors after all this, investigate drivers or software as a separate cause.
Tools and parts
- Bootable USB drive for MemTest86
When to call a pro
If a memory test confirms errors and swapping sticks doesn't resolve it, replacing the faulty RAM (often under warranty) is the fix.
