How I mprime is optimal to use to quickly isolate bad individual memory DIMM, or trigger a motherboard's memory DIMM slot to report errors.
How we use mprime for CPU/Memory burn-in. Instructions are for Linux. For Windows, use Prime95 and use the same instructions as below.

## Usually wget files into a new directory to keep extracted files in one place, otherwise you will get logs/readme's filling up wherever you're currently in mkdir mprime cd mprime wget http://www.mersenne.org/ftp_root/gimps/p95v303b6.linux64.tar.gz tar -xf p95v303b6.linux64.tar.gz |
Do not use for non-server >40 core/thread single-processor systems. mprime/Prime95 is written in Assembly language, which greatly increases the amount of system resources than most programs; running this might be too extreme for your current system, and you may mistaken the results (i.e. abrupt shutdown) as a hardware issue, whereas it just may be a limitation of your system's ability to control system hardware temperatures.
Using mprime
I only use option 16 (Options/Torture Test) since we just need mprime for stress testing. It will max the detected threads across all CPU's, I just hit 'enter' when it asks 'Number of torture test threads to run (x):'.
...
The procedures to run the mprime test above will not change much, but the outcomes will. For example, I try not to have any other processes running when using mprime. It was fine before scalable processes where CPU cache sizes were significantly smaller, but any other memory-related processes may kill mprime without any specific reason in the 'results.txt'. An example is trying to run the GPU standalone test in this article GPU Validation Test while trying to run mprime. To test high wattage/TDP, I will run mprime test 2 to max out CPU, and then GPU Validation Test to (almost) max TDP across ALL installed GPU's that are CUDA-capable (i.e. mprime will run two CPU's to 120-140w each, and GPU Validation will run ~250-300W on each GPU). Memory/blend test not ran with GPU Validation since it will cause stability issues with memory.
