Real RAM‑related Windows error codes, what they mean, and how to fix them.
RAM Error Codes & Fixes
| Error Code | What It Means | Fix |
|---|---|---|
| 0x1A – MEMORY_MANAGEMENT | Windows detected memory corruption. | Run a memory test, reseat RAM, disable XMP/overclock. |
| 0x12B – MEMORY_MANAGEMENT | Severe memory corruption. | Test each RAM stick individually, try different motherboard slots. |
| 0x50 – PAGE_FAULT_IN_NONPAGED_AREA | RAM returned invalid data. | Remove overclock, check RAM timings, run memory diagnostics. |
| 0x7E – SYSTEM_THREAD_EXCEPTION_NOT_HANDLED | Memory access violation. | Check RAM temperature, test RAM stability. |
| 0x8E – KERNEL_MODE_EXCEPTION_NOT_HANDLED | CPU tried to read bad memory. | Test RAM, reset BIOS to defaults, check for corrupted SPD data. |
| 0x124 – WHEA_UNCORRECTABLE_ERROR | Hardware error (RAM, CPU, or memory controller). | Lower XMP/overclock, test RAM, check CPU and motherboard stability. |
| 0x9C – MACHINE_CHECK_EXCEPTION | CPU detected ECC or parity failure. | Check ECC logs (if available), test RAM, inspect motherboard. |
| ECC Correctable Error | Single‑bit memory error fixed automatically. | Monitor error count, improve cooling, replace RAM if errors increase. |
| ECC Uncorrectable Error | Multi‑bit memory corruption. | Replace RAM, check motherboard memory controller. |
| Parity Error | RAM returned mismatched parity bits. | Replace RAM, inspect motherboard traces and slots. |
