Errors with memtest or fails with all memory
Question
Errors with memtest or fails with all memory.
Answer
Any error with memtest can be an indication of bad settings, faulty memory, or other hardware related issues. Below are known reasons why you may encounter errors while testing your computers memory.
Overclocked computer / CMOS setup settings
If the memory is overclocked or you've adjusted the memory settings in CMOS setup its recommend that you reset the CMOS settings to the default or factory default settings and try running the test again.
If your CMOS setup allows for your memory timing or CAS settings to be adjusted and you're getting memory errors, make sure these settings are also set to their lowest values.
Incompatibilities
Different types, manufacturers, or sizes of memory in the same computer can cause incompatibilities. If your computer is using different memory types try removing that memory from the computer and running the test again.
If you've been using the same memory in the computer and started encountering errors you may be encountering one of the other issues mentioned below. If possible try testing each memory stick individually.
Computer is overheating
A computer that is overheating can also encounter memory errors during the test. To help verify that your computer is not overheating and causing memory errors open your case and make sure all fans in the computer are working and try leaving the side of your case open for extra airflow during the test.
Temporarily remove other hardware
To help eliminate the possibility of other hardware in the computer causing memory issues remove all hardware that is not required to run the test. This can include: external drives, USB devices, expansion cards, hard disk drive, etc. Once these have been removed re-run the test to determine if they're the cause of memory errors.
If after doing this you get no memory errors, re-connect each device until you can isolate what device is causing the problem.
Swap / change memory
If you have another computer with compatible memory swapping the known good memory into your computer and re-running memtest is a good method to see if it's the memory at fault or your computer.
Bad motherboard, processor, PSU, or other hardware
Finally, if all the above steps have been attempted and you continue to experience issues your computer likely has defective hardware that is causing your memory errors. This could be a bad motherboard, processor or PSU.
