How to check the processor for operability? Program for testing the processor

The central processor in any computersystem is almost the most important component, since it is on it that all operations and calculations are assigned. Therefore, its condition should be monitored so that there is no overheating, physical damage or something else. The question naturally arises as to how to test the processor for operability. To do this, you can use several common methods.

What are the threats of the CPU?

First of all, speaking of possible failuresprocessor chip, it should be noted that as a result of its damage the entire computer system will stop working. At best, with partial damage, the computer will behave inadequately (uncaused freezes, spontaneous reboot, severe overheating, inability to launch programs, etc.).

how to test the processor for operability

In the end, the system will simply fail,not to mention the fact that the failure of the processor may entail and violations in the operation of other "iron" components installed on the motherboard. To prevent such a situation, you need to perform a CPU check at certain intervals. How to test the processor for performance, now and will be considered.

Main symptoms of failure

In any computer there is a special primaryI / O system, which stores the main parameters and settings of all devices installed in the system. It's about the structure of the BIOS and its new version of UEFI.

While turning on your computer or laptopall health parameters are checked, and only then does the start of the operating system start. Many probably noticed the characteristic jerky signal of the system dynamics right after switching on. It indicates that all components are working properly. In case of failure of any of them, a sequence of signals is issued.

Depending on the manufacturer, recognizeViolations in the work of the processor can only be provided that the technical documentation is studied. There are also standard combinations. For example, the BIOS AMI produces five short sounds. The Phoenix BIOS uses a combination of four signals. Then a pause, two more signals, again a pause, and four more signals (such a sequence is also called 4-2-4).

As for the launch, in addition to BIOS signals,direct signs of violations in the processor can be the inability to boot the system (even with the present indication) or start, after which any application freezes.

Physical troubleshooting

The test of Intel or AMD processors can be started withphysical intervention. To do this, remove the processor from the socket of the motherboard and check its performance on another computer. If the problem appears there, it will only be necessary to replace the processor. At best, you can try to apply an additional layer of thermal paste, which reduces the heating of the CPU.

program for testing the processor

But without special knowledge to conduct suchprocedure will be quite problematic. Therefore, it is better to use special applications. Any program for testing a processor can be assigned to one of two types: either it is a general test, or only strictly defined parameters are checked (it's not about CPU load control programs at the moment).

CPU Test: General Test

For general verification, suchcommon utilities like CPU-Z or Hot CPU Tester. When you start the testing process, all the indicators related to the CPU will be determined. But, if CPU-Z is a more informative application, then Hot CPU Tester belongs to the class of test utilities.

program archiver

The program for diagnosing the CPU Hot CPUTester in use is very simple. It is enough after starting in the main window to click the Test Test button. After a while, a report will be presented, which can be printed. The only thing that should be paid attention is that before starting the test it is recommended to close all currently active programs, since braking can be observed in the work of the test application. At the same time, only that in the normal mode the verification process has passed without failures, it can already indicate that the processor is in order.

Testing of temperature indicators

If we talk about which program forCPU testing in terms of temperature indicators is preferable, it is especially worth noting such utilities as HWMonitor (section of the application CPUID Hardware Monitor), Core Temp, Open Hardware Monitor and others. Application interfaces are quite similar and do not cause special difficulties in use.

diagnostic program

Some of these utilities areportable versions, so first you need an archiver program to unpack the contents of the archive, after which the application can be launched without first installing it on the computer. The displayed parameters are also very similar, so it does not matter which of these utilities will be used for the verification.

Program for diagnosing the processor in the stress test mode

There is another method of verification, calledstress test. Its essence is to diagnose possible malfunctions in the work of the CPU at critical (peak) loads. For this purpose, the utility called CPU Stress Test or CST short is best.

Again, the application is aa portable version that does not require installation, and at best it will take an archiver program to unpack the downloaded archive. This application is very interesting in terms of functionality.

processor check

How to check the processor for operability with itshelp? Very simple. You just need to activate the start of the diagnostic process, after which the application, using SSE-commands, immediately begins to increase the load on the processor to 100%, and even with the temperature rise to critical values. As you can see, all active programs must be closed for the duration of the test.

processor malfunction

In principle, you can use the utility Prime95, which, unlike the first, gives a load not only on the CPU, but on all components in general.

Performance test

Finally, let's see how to test the processor for performance on performance indicators. To do this, it is best to use the unique Super PI application.

test of intel processors

It is based on calculating the value of the number "pi" inrange from 16 thousand to 32 million decimal places. How to evaluate the result? Yes, just look at the time spent on the operation and compare it with the performance of similar processors, for example, on the site of the program or the resource of the processor manufacturer. In general, it is this utility that most overclockers use to overclock processors, thus assessing performance gains.


It remains to say that to use any oneprogram is not worth it, because each of them can be designed for strictly defined tests. It is better to conduct a comprehensive test using several utilities. Even applications for general testing or purely informative programs do not give a complete picture of all possible violations in the work of the processor.

Which utility to use to run thator any other task, it is rather difficult to advise because of the thousands on the Internet today. Here, only some types of programs were considered, so that any user at least got an idea of ​​the general principles of verifying processors and possible tests.

As for what the test showsa negative result, you will either have to contact specialized centers where specialists can take some steps to troubleshoot problems or simply change the processor, because each CPU has its average lifespan, after which no physical intervention will make it work, as it should be.
