. To keep it "quick," you can configure it to stop after a single pass. : Create a bootable USB drive using the MemTest86 official tool Configuration : Boot from the USB and go to Test Selection Number of Passes : A single pass typically takes about 1 hour per 8GB of memory, though this varies by RAM speed. Efficiency
| Result | What It Means | Next Step | |--------|--------------|------------| | after 1 pass | RAM is probably fine for basic use. No catastrophic failure. | Run a longer test overnight for confidence, or consider other components (CPU, motherboard). | | 1+ errors in <15 min | Your RAM has a hard fault. Replace it immediately. | Test each stick individually to isolate the bad module. | | System freezes / reboots during test | Severe failure—likely a shorted or completely dead DIMM. | Remove all but one stick. Retest. |
