Software guide: Useful Utilities for overclocking and not only. Testing Equipment in Linux Linux Processor Testing Inscription

This material is intended to register readers in today's manifold software for configuring, evaluating performance and overclocking system components, as well as monitoring data tracking. The basis of this article make up useful links to download the appropriate applications.

Drivers: Platform

Correct driver selection for various system nodes, in particular elements motherboard and GPU video cards are extremely important for stable PC operation. Where special "creativity" is not required, so it is when installing drivers coming in a set with motherboard. Nevertheless, you can always find and install fresh versions Drivers for chipset, audio controller and Wi-Fi cards (if any).

Benchmarking

Methods for estimating the performance of the system of the system of a great set, and each experienced enthusiast is their own. Listed below are the most simple ways, and in-depth testing you can spend using the application set of applications from among those mentioned in processor reviews, video cards, memory modules and other components on our website.

Presenting a rendering of a 3D scene, enjoys considerable popularity. It is free, shows stable results and can upload up to 256 processor streams (256 aMD cores Bulldozer or 128 cores Intel Core With Hyper-Threading). More or less relevant, especially in the context of competitive benchmarking, previous version This application -

RivaTuner Statistics Server Auxiliary Utilities (RTSS) and FRAPS will help measure the frame frequency in games that do not have built-in benchmarks. With their help, you can write game rollers. The FRAPS interface is easier, but the updates of this utility have not been produced for almost two years.

So, we have considered the most useful and in demand by enthusiasts of the program to configure, monitor, overclocking and testing PC nodes. To date, the choice of utilities for these purposes is huge, and in the article, most likely, not all of the applications that you personally use are mentioned. Write on your own preferences in the comments to this material.

Will cope when the load on the processor reaches 100 percent. Thus, it is possible to identify problems with cooling and solve them before they create real inconvenience. In this material, we will tell about how to conduct a processor test stress using LINX and OCCT programs.

One of the most famous programs for stress testing processor is the LINX program. This program Completely free and is a graphical interface for the LINPACK program developed by intel.. With this program, you can create a limit load on the processor and thereby find out to what temperature the processor will warm up.

In order to conduct a stress test processor using LINX, to your computer, unpack any folder and run the linx.exe file. After starting the program, you will see approximately such a window as in the screenshot below. Here there are two "Start" and "Stop" buttons with their help you can run and stop the stress test.

But, do not rush to run LINX. You still need some kind. For this purpose, you can use HWMONITOR. This program is designed to observe current parameters Systems. With it, you can track the temperature, load, the speed of rotation of the coolers and much more.

Install and run on your computer. After startup, scroll through the list of the parameters that tracks HWMonitor to processor parameters. When stress testing, you need to pay attention to the speed of rotation of the coolers, temperature and clock frequency of the processor.

After everything is ready, you can run LINX test stres. To do this, just click on the "Start" button.

After starting stress testing, we start watching the processor temperature in the HWMONITOR program. If the processor cooling system is working, then at first the temperature will increase dramatically, but after the fans are promoted to full power It should decrease and stabilize at one mark. In the screenshot below, it can be seen that the temperature first jumped up to 80 degrees (MAX column), and then dropped to 72 degrees (Value column).

If the cooling system of the processor is faulty or it simply does not cope with heating, the temperature will continue to grow throughout the dough stress. If the temperature oversteps the mark of 80 degrees and continue to increase, then testing is better to interrupt so as not to bring the computer before the emergency reboot.

To turn off the test stress simply click on the "Stop" button in the LINX program. If the computer is hung, and the "Stop" button does not work, then restart the computer with the RESET button on the system unit.

Testing a processor using OCCT

OCCT - another very popular program for stress testing processor. OCCT is equipped with two processor testing algorithms at once. This is a LINPACK, which is used in LINX, as well as its own OCCT algorithm. In this case, the OCCT is equipped with a more advanced interface. With it, you can track the temperature, load and other processor parameters. So when testing with OCCT, the HWMONITOR program is no longer needed.

In order to conduct a processor test stress using OCCT, install and run on your computer. Next, you need to go to the Test tab that you want to use and click on the "ON" button.

Further all just like with LINX. If the processor cooling system is properly, the temperature will first join, and then it will decrease and stabilizes on some mark. If the cooling system is not proper or does not cope with the load, the temperature will continue to grow. In this case, the stress test must be stopped.

To properly test the cooling system and the stability of work in overclocking, when to achieve high frequencies, it is also necessary to raise the voltage, you need to load it under the string for a pretty long time. This will only help special utilitieswhich can boot the processor on the taste, complex, but meaningless calculations. Here the main thing is to take the "right" program to work effectively using complex floating point formulas to handle a large amount of data. Perhaps one of the best utilities Created an Intel called LINPACK. True, it was done by programmers for advanced users, without frightening over the windows with ruffles, limiting command line. Black screen with incomprehensible running rows robbles ordinary users Computer into a stupor that do not understand what to do with these and where to click the mouse. Glory to God found good people who screwed to LINPACK graphic shell, calling your creation Linx.

LINX does not have to install, and you will need to download archive file., unpack it, go to the created folder and start the executable file linx.exe. To delete the program, it will be enough to delete the folder where the LINX files threw off, the main thing is not forget, as it is called and where to be.

The fact that the creating tests are intel are not worth worrying about the efficiency of working with aMD processors, LINX perfectly loads processors as Intel and AMD.

After launching LINX, the program is actually ready to work for this enough to press the "Start" button at the top with right side. Further, gain patience and wait until the specified number of tests in a circle takes place. When the test cycle is completed in the table, its results will be added, namely the time, the data processing speed, the number of streams used and the system matrix size linear equationswhich was used for calculations. At a time, loading the processor to the maximum, allowing you to check it on the stability of the work and the efficiency of heat removal of the cooling system.

To stop the test run, just press "TOP".

In the main window in top string Under the main menu there are sections where users can change:

  • "Task volume:", indicate the size of the matrix of the system of linear equations, which will be used for calculations. The more, the longer the calculations go. Note, this parameter is associated with "Memory", that is, when one of them changes, another will automatically change.
  • "Memory (MIB)", the amount of RAM, which the program can use the program. As mentioned above, with an increase in volume, it will automatically change "the volume of the task:", the same way.
  • "Perform" how many test runs will be done in a circle.

Of the interesting features of the program, it costs to note the support of obtaining data on the temperature of the processor, the frequencies of the core and supply voltage from the EVEREST / SPEEDFAN applications and display them in the form of graphs during tests. Plus allow stopping tests when errors occur or if the processor is heated above specified value (only when working in Evered / Speedfan pair). Also in the settings, you can specify the number of threads, which will be performed at the same time, select the title of tests 32 or 64-bit, the priority of testing processes (it is better to leave the default, so that the computer does not slow down), and limit the scope of the program memory used, so that the operating system is not Brake.

To date, LINX, and if you are completely accurate, then linpack if you lean the graphics shell, the only test that allows you to adequately check the stability of the processor. Consider, this program creates very high loads on the processor, under which it will never work at home, and it is not desirable to constantly launch it on your computer for several hours. Especially in the light of the fact that everyone intel processors The last generations under the lid of the terminal, which, with long-term exposure, high temperatures, can over time to lose its properties.

The program works both in 32 and 64-bit operating systems. The program interface is translated into English and Russian, users must download the desired version Program with appropriate localization.

Monitoring is carried out using a program kit lM-Sensors..

We check the support of the 3D acceleration by means of the video card:


glxinfo | Grep Direct.

If 3D support is implemented, the output will be:


Direct Rendering: YES

Check the speed of 3D:


GlxGears.

A window with a simple 3D animation will appear. In the console, there will be information about the rendering speed every 5 seconds. Normal FPS values \u200b\u200bfor the configured driver must be on average above 1000 (if vertical synchronization is enabled, the FPS value will be limited to the synchronization frequency).

Another test OpenGL:


USR / LIB / XSCREENSAUR / GLBLUR -FPS

A screensaver window appears, in which the FPS value will be displayed.

In case of any problems, you can reinstall the video driver (for embedded intel video cards you need to reinstall the package xserver-Xorg-Video-Intel). Driver settings are carried out by the program. driconf.. Also to control the operation of the Intel video card you can install the package intel-GPU-Tools (The package includes the Intel_GPU_TOP utility, allowing real-time monitoring the loading of the video processor).
