Is there a problem with the motherboard, or is it more about your skills?
Single core or multi-core setup, but I didn’t begin the Cinebench test because my VRM reached 57°C.
Multi-core configuration enabled. Turn off the test duration setting as well. What is the time it takes for programs to begin crashing?
It's unpredictable—may take anywhere from 5 minutes to 30 minutes.
Have you experimented with your RAM?
