| Error Pattern | Likely Cause | Action | | :--- | :--- | :--- | | Single bit error, same address, every run | One dead memory chip | Replace the specific stick. | | Random addresses, different bits | Faulty memory controller (CPU) or power regulation | Test RAM in a different PC. If passes, replace CPU/mobo. | | Errors only on cold boot | Cold solder joint or capacitor | RMA the motherboard or RAM. | | Errors only on Pass 5+ | Thermal expansion failure | Improve case airflow; replace RAM. |
