Is multithreading necessary in games? Implementation of multi-threaded game engine architecture. Let's move on to the instructions...

All modern computers are multi-core devices, which affect system performance. However, Windows 7, like any other operating system, does not use the processor cores to their full capacity. This is due to saving resources on the PC itself. Therefore, if your programs do not slow down and errors do not occur, we do not recommend using all the cores of the graphics accelerator. This action should be performed in cases where the PC power is not enough to run standard programs and games.

Configuring kernels through the startup menu

This option for using all the processor power is the simplest and safest. It is suitable for all versions of Windows OS (except XP). Any user, even a beginner, can perform the above steps.

  • Press “Win+R” and enter “msconfig”.
  • The System Configuration window will open. Go to the “Download” tab and click “Advanced options”.

  • In the window that appears, check the “Number of processors” box so that the item with the choice of cores becomes active. We set the maximum memory.

  • Afterwards we save the result and reboot the system. Multitasking mode will turn on.

IMPORTANT! If your PC turns off during advanced settings, check whether your power supply has enough power.

Advanced CPU settings with AIDA64

The AIDA64 program is useful not only for its reports on the status and characteristics of individual PC components, but also for its functions of unlocking processor cores. To use the CPU capabilities using this program, you should do the following:

  • We launch the program and select “Motherboard”, “CPU” in the menu on the left.

  • Next, turn on each of the cores and reboot the system.

If the involved kernels did not bring benefits, it is worth returning the settings back.

Using CPU Cores Using CPU-Z

The CPU-Z program allows you not only to check what characteristics a particular PC component has, but also to optimize the operation of some of them. In order to enable all kernels, you must do the following:

  • Let's launch the program. Go to the “CPU” tab.
  • In the “Theads” item you need to set the value the same as in “Cores”.

  • After rebooting the system, you need to check the changed parameters.

Overclocking the processor using BIOS settings

To use all the cores of the graphics accelerator, you should go to the BIOS. To do this, restart your PC and press “F2” or “Del” several times. Then you need to make the following settings:

  • Find the “Clock Calibration” section (It is only available for AMD products). Set the value to “All Cores”. In the “Value” item we set the value as a percentage.

  • After rebooting the system, it is worth checking the PC for functionality.

These methods are quite simple and in rare cases cause the system to crash. However, if after editing the settings errors begin to appear, you should stop unlocking the cores and return the settings back.

To learn how to enable processor cores on a PC with Windows 7 and higher, watch the video:

Personal computers and laptops with multi-core processors have enormous computing power. Thanks to the parallel operation of all cores, the device is able to show impressive performance in computer games and programs. In this article we will figure out how to enable all cores on Windows 10, which applications can be used to view information about the processor, and so on.

Depending on the workload of the computer, the occupancy level of each core may differ from the others. In addition, each core is capable of operating at a separately set frequency due to BIOS settings or motherboard software. The load on the computer is distributed evenly, which is why you get high performance.

There is only one case when a dual-core processor will not use the second core - this is the procedure for turning on the PC. To start the operating system and get the computer ready, the BIOS uses the resources of only one core. You can use all the resources and speed up the process of turning on your computer a little. However, you should not expect significant changes - speeding up the PC startup must be achieved using other methods (for example, installing it on an SSD).

Switching methods

You can activate all 4 cores in a 4-core processor when you boot your computer using the following methods:

  • through standard system tools;
  • through settings

The instructions described below are suitable for 32 bit and 64 bit OS. Home, Pro and Enterprise versions are supported. In order for the computer to begin using all its power at startup, the following operation must be performed:

  1. Go to the Run application using the Win + R keys. Enter the line “msconfig” and press Enter to run.

  1. In the window that opens, you will see the “Download” tab.

  1. In it you need to select your OS and click on the “Advanced boot options” button.

  1. Check the “Number of processors” checkbox and set the maximum number of cores. You also need to increase the “Maximum Memory”. The PCI Blocking setting must be disabled to ensure that the computer distributes the load evenly across all the cores. To complete the settings, close the window with the “OK” button.

Tip: You cannot set the maximum memory amount to less than 1024 MB, so as not to achieve the opposite effect - slowing down the computer boot.

After saving the settings, you need to see how many cores are running now. If all parameters are reset, then reduce the “Maximum Memory” and test again. To avoid repeating this procedure, in the “System Configuration” window, check the box next to “Make these boot parameters permanent” and finish the job with the “OK” button.

In BIOS

It is worth warning that changing BIOS settings is recommended only if your personal computer stops booting. Without minimal knowledge, we do not advise you to use this method if the one described above works.

So, to enable a multi-core processor you need to:

  1. Launch BIOS menu. This is done when you turn on the computer. On different motherboards, a separate key is responsible for starting. On most computers these are Del, F1, F2, F10 and similar system buttons. On the loading screen you will find information about your key.

  1. In the BIOS menu you need to open the “Advanced Clock Calibration” section. Here you need to set the “All Cores” parameter.

  1. To save and reboot, press F10 and confirm with the Y key.

Now you know how to boot your computer using all processor cores.

How to find processor information

You can find out how many cores your PC has and what specifications the CPU has in the following ways:

  • standard OS tools;
  • third party utilities.

First, let's look at the built-in capabilities of the operating system.

general information

You can view information about the processor and its characteristics as follows:

  1. Go to "Options". To do this, right-click on the “Start” icon and click on “Options” in the menu.

  1. Next, go to the “System” section.

  1. Now open the “About the system” section.

  1. In the list of all information, find the marked line. The name and frequency of each core are indicated here.

You can learn more about the equipment through the “Device Manager”. All ways to open this program are presented below:

  1. To open Device Manager, enter the appropriate query in the search bar.

  1. You can also launch the program through the Control Panel. Open it in any convenient way, and then go to “Hardware and Sound” (1).

  1. Next, click on “Device Manager”.

  1. At the command prompt, you need to enter “mmc devmgmt.msc” to launch Device Manager.

The application window looks like this:

In it you need to expand the “Processors” branch. The screenshot shows a 4-core device as you see 4 identical lines. Right-click on one of the lines and select “Properties”. In the window that opens you can find all the information on the processor.

Third party utilities

If you are not satisfied with the functionality of Device Manager, you can install one of the third-party utilities. The most common are CPU-Z, AIDA64 and Everest.

CPU-Z can be downloaded from the official website using the link. When you launch it for the first time, the utility will collect data about your PC configuration. The first tab contains all the information about the CPU:

In the remaining tabs you will find a detailed description of other equipment. For example, the SPD will contain a detailed description of the RAM (Module Size, Manufacturer, and so on).

The AIDA64 program is downloaded from the creators' resource. On the left side of the window you need to open the “Motherboard” branch and go to the CPU subsection. The Multi CPU column will indicate the number of processors:

The latest utility is Everest. It is very similar to the previous software. It also contains all the information you are interested in about the CPU in the “Motherboard” section:

Results

Enabling multithreading is possible only for the operation of starting a personal computer. In all other cases, the CPU uses all resources simultaneously, so there is no need for manual configuration.

Video

Below is a video instruction with a detailed description of all the actions and operations from this article. With the help of a visual aid, you will be able to understand the points and steps of the manual that are unclear to you.

Hello friends! I myself recently learned that Windows 7 has an option that, when turned on, uses all the cores on the processor when you turn on the computer. That is, if you have a multi-core processor, two cores or more, then you can speed up the loading of Windows 7 by simply enabling the use of all cores.

There are many ways to speed up your computer boot time, the best one is probably buying an SSD drive. But they are expensive, so why not try to increase the boot speed of Windows 7 at least a little by simply connecting all the cores on the processor to this process. Let's jump straight to the instructions.

Using a multi-core processor when turning on the computer

In Windows 7, go to “Start”, "All programs", “Standards” and launch the “Run” utility.

A window will appear in which we type the command msconfig and click “Ok”.

In the window that opens, you need to check the box next to “Number of processors” and in the list select how many cores to use when turning on the computer. I advise you to choose the maximum number of cores you have. As you can see, I have a dual-core processor, so only two. You may have more. To save, click “Ok”.

That's all, restart your computer and observe the result. Good luck!

How to enable all kernels on Windows 7? Users often ask this question and get stuck from time to time.

Even multi-core devices may experience stuttering. Let's take a closer look, how to effectively speed up your PC and “force” the system to use all available cores to their fullest.

Modern computers are multi-core devices. However, no operating system uses all cores to their full capacity.

Such a limitation is necessary to save resources on PCs and laptops.

Modern hardware technologies allow "load" the required number of cores when working with certain programs that require more performance.

If your PC doesn't start running faster even when running a powerful photo editor, game, or editing program, you'll need to adjust the processor usage mode yourself.

Method 1 – Setting up multitasking in OS startup mode

This setup option is one of the simplest and most effective. The bottom line is that the processor is overclocked immediately.

The user can always change the settings and return the original parameters.

Follow the instructions:

  • Open the command window using the Win + R key combination;
  • In the text field of the window that opens, enter the system configuration command msconfig;

Rice. 1 – calling the Windows configuration window

  • Now go to the downloads tab. Here you can view the version of the installed OS, configure safe mode and other boot options;
  • Press advanced options key;

Rice. 2 – Windows configuration window

  • In the tab that opens, you can select the mode for using the available computing characteristics of your PC. Check the boxes next to the number of processors and maximum memory. These lines were previously inactive because the computer was in resource-saving mode;
  • Select the highest number of cores and the maximum amount of available memory;

Rice. 3 – setting up boot parameters

After turning on the computer again, multitasking mode is activated. The user can also choose fewer processors and memory.

The optimal number for fast work is 5-6 cores and 1024 MB of memory for each processor.

Method 2 - BIOS setup

Another option for adjusting the operating speed of the OS is to add new settings in the BIOS.

This option allows you not only to increase the efficiency of completing tasks, but also prevents crashes that occur in the OS and the regular appearance of a blue screen.

The program allows for comprehensive configuration of hardware and software components:

  • Processor;
  • Cache;
  • Motherboard;
  • Memory;
  • System module parameters (Serial Presence Detect).

To enable all cores we need the CPU tab. The figure below shows the configuration display window in the CPU-Z application.

At the bottom there is a Cores field, its value is the number of PC cores that operate at the same frequency. Enter the maximum number of processors in the field.

The Threads field must be equal to Cores.

Rice. 5 – main window of the CPU-Z application

After making changes, press the “OK” button. Turn off the program and restart the device.

Method 4 – AIDA64 program

Another good program for adjusting the number of cores used is . Application Features:

  • Ability to view the hardware characteristics of a PC or laptop;
  • Generating reports on device operation;
  • Displaying the characteristics of the installed OS;
  • Ability to change processor usage parameters;
  • PC speed testing function.

First, look at how many cores are available in your PC. The information is located in the Multi CPU tab (on the left side of the window, select "Motherboard"-“CPU”):

Rice. 6 – main window of the AIDA64 utility

Turn on each of the cores. Restart the program and check if the processor activation has failed. This can happen due to a conflict between the program and the hardware components of the PC.

You should repeat the setup again. All that remains is to re-use it and enjoy its fast work.

It is advisable to activate all cores if there is an urgent need to perform complex operations in the process of editing videos or to speed up the operation of video games.

If your computer is too slow without using all the cores, this may indicate a failure in the OS.

A set of actions should be carried out to optimize the operation of the operating system.

OS optimization

Computer optimization is actions that result in errors occurring less frequently.

How to optimize Windows? This procedure is carried out the same way, regardless of the system version.

To speed up your browser and other programs, close unnecessary processes in the Device Manager window.

And also clear the tab of unwanted software that starts when the OS is turned on and operates in the background.

Cleaning your hard drive of unnecessary files and other junk will help improve overall system performance.

Go to the “My Computer” tab, click on the storage medium icon and open the properties window.

Select Disk Cleanup and wait until the report on unnecessary files is generated. Clear all data by checking unnecessary fields.

Rice. 7 – Windows 7 optimization

Owners of powerful computer systems based on multi-core processors, of course, try to “squeeze” everything possible out of them in terms of increasing the performance of machines running, for example, Windows 7 or the like. But not everyone knows how to enable kernels on a “computer”. Windows 7, as well as newer systems, offers a universal solution, which will be discussed below.

What does enabling all processor cores do?

Many users have a rather distorted opinion about the system using all processor cores. Remember, you can enable two or four cores, but this is not the same as using two or four processors! The performance gain will not be as expected.

Transferring or reading data will be faster, but the amount of information processed will remain the same. To understand why and how to enable all cores on Windows 7 (and, in general, whether it’s worth doing), let’s draw some analogy with eating. It goes without saying that you can put food into your mouth with one hand, or with both. In this case, the hands are the processor cores. It is clear that using both hands will make the process much faster. But here’s the problem: when your mouth is full, no hands, even four or six, will help. There will simply be nowhere to put food.

Exactly the same thing is happening with computing capabilities. Here, only the optimization of the number of operations performed in a certain period of time by each core occurs, but the total volume remains the same, and, as they say, you cannot jump higher than this indicator.

How to enable everything on Windows 7 when changing BIOS settings

So, first, let's consider the most unpleasant situation, when for some reason changes were made to the BIOS parameters, settings were reset, or the system simply crashed.

In this case, when deciding how to enable all kernels on Windows 7, you need to rely on specific settings. To do this, use a section called "Advanced Clock Calibration", where the default value should be set to "Auto" or "All Cores" (in different BIOS modifications, the names of the sections may differ or be in tabs with other parameters).

After applying the changed settings, you only need to reboot the system. In theory, if there are no failures in the BIOS itself, all processor cores will be used automatically.

How to enable all kernels on Windows 7 using system configuration tools

However, even if the BIOS settings are configured correctly, and the processor cores are still not used, you can use the operating system’s own tools.

How to enable all kernels on Windows 7 in this situation? Here you need to call the “Run” menu and enter the “msconfig” command there to enter the configuration parameters. Here we have the “Download” tab we need. Just below the main window there is a button for additional parameters. Clicking on it takes us to the settings menu.

On the left we use the line for the number of processors and select the number corresponding to the number of cores. Don’t worry, the system will not display more than there actually are. For example, we need to solve the problem of how to enable 4 cores on Windows 7. As is already clear, we select exactly this number from the list. After the changes have been made, save the configuration and restart the computer.

But there are pitfalls here. You need to be very careful with such operations. It is important to know that when enabled, each core must have at least 1 GB (1024 MB) of RAM. If the RAM levels do not meet the required values, there is no point in trying. This way you can only get the opposite effect. In this case we are talking about hand-assembled stationary computers. This does not threaten laptops (if the equipment has not been changed), since any manufacturer takes into account the possibility of using all cores of the processor system. Please note that for 2-core processors, as a rule, at least 2 GB of RAM corresponds, for 4-core processors - at least 4 GB, etc.

Debugging and PCI blocking items must be disabled.

Instead of an afterword

So we figured out how to enable all processor cores in Windows 7. In general, as is already clear, this process in Windows 7 and higher does not cause any particular difficulties. Another thing is that you need to analyze in advance to see if the number of cores and RAM sticks matches, because as a result, the computer may completely slow down or, in general, fail. So it’s better not to joke with such settings unless you are firmly convinced that enabling absolutely all cores is absolutely necessary.

However, there should be no problems with the BIOS. Most systems, when reset to default settings, intend to make maximum use of the capabilities of modern multi-core processors. This decision was made, so to speak, as a last resort.
