Basic introduction
Prime95 segment first LOGO
Prime95 is a software specially designed to test system stability. Prime95 is recognized as the most cruel among all copying software. Prime95 loads the CPU with an absurdly high workload to test the CPU's endurance. Through testing, it can discover stability issues that other testing programs cannot. Huajun Software Park provides you with Prime95 download.

Prime95 software introduction

Prime95 and Super π are similar in that they both use continuous calculation functions to test system stability. However, the test environment of Prime95 is very harsh. Even a system that can successfully pass 4.19 million tests in Super π may not be able to survive a few minutes in Prime95. Many players use Prime95 to test the stability of the CPU after overclocking and use it as a basis for successful overclocking. The Prime95 test has attracted much attention from players because it can find stability problems that other test programs cannot find. It is also used by many professional computer OEM manufacturers to determine the stability of computers.

      How to use Prime95 to test CPU stability?

Prime95 download includes 32-bit and 64-bit versions,For 32-bit, use 32-bit, and for 64-bit, use 64-bit.

​ ​ 1. The name of the software used here to test CPU stability is "Prime95". This is a free green software. You can download it from this site, unzip it to your computer and run it directly.

3. Next, in the test options, select the first item and keep other settings unchanged. This item is mainly used to test the floating point operations of the CPU, and also tests the filling of the CPU's cache. After selecting, click the "OK" button, as shown in the figure:

4. Then the Prime95 software will automatically perform a stress test on the current computer CPU. The CPU of my current computer is a quad-core, so you will see "Work #1-4". Each Work area represents a logical CPU core, as shown in the figure:

5. Then you can open the system’s task manager. In the performance list, you can see that the CPU utilization will be very high, as shown in the figure:

6. Under normal circumstances, the test time is 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, the temperature of the CPU increases because the CPU utilization is always dealing with high load. If the CPU fan fails to dissipate heat effectively, it may cause automatic power outage.

7. 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, as shown in the figure:

Prime95 FAQ

      How long does it take for the Prime95 test to be considered stable?

It is advisable to run the Prime95 test for no more than 3 hours for two reasons: first, a system that can pass the 3-hour Prime95 test is already very stable; second, running the Prime95 test for too long may cause CPU damage. Because many components are working under heavy load during the Prime95 test, such as the CPU, North Bridge and motherboard power supply module (especially the motherboard power supply module that is directly exposed to the air). Therefore, heat dissipation of these components must be done well to prevent accidents.
