A method to test the stability of CPU performance with Prime95

a method for testing CPU performance stability with Prime95. Many netizens have encountered such a problem, that is, when using a computer to watch video, the computer will suddenly crash, blue screen or even shutdown restart. This may be related to computer CPU performance instability. So how do you look at the stability of CPU performance? The software we recommend to use is: Prime95. Below, look at the specific view Method!

How to use CPU test software:

First, here to use the test CPU stable software name called "Prime95", this is a free stunning software, can be downloaded through Baidu Search, decompression to the computer directly run. After decompression, enter the software directory, run the "Prime95" executable file directly, as shown in the figure:

Second, the software will pop up the selection dialog box when it is first used. We choose "Just Stress testing" here, as shown in the picture:

Third, next in the test option, we select the first item, the other settings remain unchanged. This is primarily used to test floating-point operations on CPUs, as well as to populate the CPU cache for testing. When you choose, click the "OK" button, as shown in the picture

Four, then the software will automatically to the current computer CPU pressure test. My current computer CPU is the Quad core, so you will see "Work #1-4", each Work zone represents a logical CPU core, as shown in the figure:

Five, then we can open the system's task manager, in the performance list can see the CPU utilization will be very high, as shown in the figure:

Six, under normal circumstances, the test time is 6-24 hours. If the CPU really has hardware performance problems, it may be in a few minutes will appear abnormal conditions, such as panic, restart, automatic power outages. When we stress test the CPU, because CPU utilization has been processing high load state, so will cause the CPU temperature rise. If the CPU fan is not radiating, it may cause an automatic power outage.

If you want to stop the test, please click "Test-" stop "in the upper left corner of the software, then click" OK "button to stop all the tests, as shown in the picture:
