CPU stability test ?

Enter the software directory and run the "Prime95" executable file directly. When you use it for the first time, the software will pop up a selection dialog box.

We select “Just Stress Testing” here

Next in the testing options, we select the first item and keep other settings unchanged.

This item is mainly used to test the floating point operation of the CPU. It also tests the filling of the CPU cache.

After selecting, click the "OK" button and the software will automatically perform a stress test on the current computer CPU. The CPU of my current computer is quad-core, so you will see "Work #1-4". Each Work area represents a logical CPU core. Then we can open the system's task manager and see the CPU in the performance list. Utilization will be very typical, with test times ranging from 6 to 24 hours. If the CPU really has hardware performance problems, abnormal situations may occur within a few minutes, such as crashes, restarts, automatic power off, etc.

When we stress test the CPU, because the CPU utilization has been dealing with high load conditions, the temperature of the CPU will increase.

If the CPU fan fails to dissipate heat effectively, it may cause automatic power outage.

If you want to stop testing, please click "Test -> Stop" in the menu bar in the upper left corner of the software, and then click the "OK" button to stop all tests
