Prime95

Prime95 official edition

The official version of Prime95 is a stable tool for testing the computer system. Prime95 tests the endurance of the CPU by loading the CPU with a slightly exorbitant workload. Prime95 has a "torture test", which places CPU and RAM in the test, mainly to ensure the correct execution of applications on the specific PC. PC download network provides download service of Prime95 software. Please go to PC download network to download other versions of Prime95 software!

Prime95 Software Introduction

Prime95 and Super π are similar in that they both use non-stop calculation functions to achieve the goal of testing system stability. However, the test environment of Prime95 is very harsh, even if it can be used in Super π; The system that successfully passed 4.19 million tests in the Prime95 will not survive for several minutes. Many players use Prime95 to test the stability of the CPU after overclocking, and use it as the basis for successful overclocking. The Prime95 test has attracted the attention of many players because it can find stability problems that cannot be found by other test programs. It is also used by many professional computer OEMs to determine the stability of computers.

Prime95 software features

1. GIMPS has a new sub project - look for (possible) Mason's main supporting factors

2. Like the LL test, PRP testing now supports shift counts to help with double checking

3. PRP testing now supports a low overhead error check, which can almost guarantee correct results even on chip hardware

4. Since the PRP test is highly reliable, we now provide the option to conduct the PRP test instead of Lucas Lehmer primality test

5. For non basic 2 PRP tests, there is a new option to run each iteration twice. If there is a mismatch, roll back

Prime95 installation steps

1. First, download the Prime95 software package on the PC download network to get the zip compressed package

2. Right click the compressed package and select to unzip it to the current folder to get the Prime95 folder

3. After opening the folder, there will be 32 bit and 64 bit options. Open the corresponding folder according to the system of your computer

4. Open the corresponding folder and get the exe file. Double click to use Prime95 software without installing it

How to use Prime95

How can I use Prime95 to test CPU stability?

The Prime95 download includes 32-bit and 64 bit versions. 32-bit uses 32-bit and 64 bit uses 64 bit,

1、 The name of the software used here to test the CPU stability is "Prime95", which is a free green software. You can download it on this site, unzip it, and run it directly on your computer. After decompression, enter the software directory and directly run the "Prime95" executable file, as shown in the figure:

2、 When first used, Prime95 software will pop up the selection dialog box. Select "Just Stress Testing" here, as shown in the figure:

3、 Next, select the first item in the test option, and other settings remain unchanged. This item is mainly used to test the floating point operation of the CPU, and also to fill the CPU cache. After selection, click "OK", as shown in the figure:

4、 Then Prime95 software will automatically stress test the current computer CPU. The CPU of my current computer has four cores, so I can see "Work # 1-4" The Work area represents a logical CPU core, as shown in the figure:

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

6、 Generally, the test time is 6 to 24 hours. If the CPU really has a hardware performance problem, it may appear abnormal conditions within a few minutes, such as crash, restart, automatic power failure, etc. When we stress test the CPU, because the CPU utilization is always under high load, the CPU temperature will rise. If the heat dissipation of the CPU fan is not sufficient, it may lead to automatic power failure.

7、 If you want to stop the test, click "Test ->Stop" in the menu bar at the upper left corner of the software, and then click "OK" button to stop all tests, as shown in the figure:

Prime95 FAQs

       Q: How can I use Prime95 to test CPU stability?

A: First, the name of the software to be used here to test the stability of the CPU is "Prime95", which is a free and unique software that can be downloaded through Baidu search, decompressed to the computer and run directly. After decompression, enter the software directory and directly run the "Prime95" executable file.

2、 When using for the first time, the software will pop up a selection dialog box. We choose "Just Stress Testing" here.

3、 Next, in the test options, we select the first item, and other settings remain unchanged. This item is mainly used to test the floating point operation of the CPU, and also to fill the CPU cache. After selecting, click the "OK" button.

4、 Then the software will automatically stress test the current computer CPU. The CPU of my current computer has four cores, so I can see "Work # 1-4". Each Work area represents a logical CPU core.

5、 Then we can open the task manager of the system. In the performance list, we can see that the CPU utilization will be very high.

6、 Generally, the test time is 6 to 24 hours. If the CPU really has a hardware performance problem, it may appear abnormal conditions within a few minutes, such as crash, restart, automatic power failure, etc. When I

When we stress test the CPU, because the CPU utilization is always under high load, the temperature of the CPU will rise. If the heat dissipation of the CPU fan is not sufficient, it may lead to automatic power failure. 7、 If you want to stop testing, please click "Test ->Stop" in the menu bar at the upper left corner of the software, and then click "OK" button to stop all tests.

       Q: How long will the Prime95 test be stable?

Answer: The Prime95 test run time should not exceed 3 hours. There are two reasons: First, the system that can pass the Prime95 test for 3 hours is already very stable; Second, running the Prime95 test for too long may cause CPU damage. Many components of Prime95 work under heavy load during testing, such as CPU, North Bridge and mainboard power supply module (especially mainboard power supply module directly exposed to air). Therefore, the heat dissipation of these parts must be done well in case of accidents.
