| Result | Meaning | Recommended Action | |--------|---------|---------------------| | (any tool, full pass) | RAM is likely stable under that test condition. | No action, but retest if system still unstable. | | Errors in WMD only | Moderate issue – may cause random crashes. | Reseat RAM, test each stick individually with MemTest86. | | Errors in MemTest86 | Definite hardware fault or configuration error. | 1. Test sticks one by one. 2. Replace faulty module. 3. Lower frequency/timings if borderline. | | Errors only under TM5/OCCT | Timing/voltage sensitivity (common on DDR5). | Slight increase to DRAM voltage or loosen timings. | | System freezes / reboot during test | Likely severe RAM or IMC (memory controller) issue. | Test with JEDEC default speeds (no XMP/EXPO). | Use Windows Memory Diagnostic in Windows 11 Here
