How to enable all processor cores. How to enable all cores How to enable all cores in Windows 10

Owners of powerful PCs with multi-core processors usually want to configure the system to deliver full power to get maximum performance, but they often don't know how to do this. In this article we will look at instructions on how to enable all cores.

What result can you expect

There is a fairly common misconception that a processor with multiple cores has the same performance as a PC with multiple processors. To give an example, consider the analogy of loading material into a container for recycling. Several workers can bring the product instead of one, if you imagine that the workers are processor cores. Transferring and reading information is faster. Instructions with screenshots on how to overclock the processor.

Setting up kernels in BIOS

Sometimes, due to a dead battery on the motherboard or for some other reason, the settings are reset to default settings. In this case, you usually need to check and set the parameters manually. To do this you will need:

Enabling kernels in the configuration utility

If the BIOS settings are set correctly, but the kernels are still not active, you can try changing the settings in a special Windows configuration program. For this you will need:

After completing the operations, reboot the system.

Configuring kernels for a specific process

Using the task manager, you can enable the required number of cores for a specific program. This is done as follows:

Note: in the task manager, on the performance tab, you can see whether all cores are running at the moment. Each of them displays its own diagram.

Power Settings

Sometimes, due to power settings, the computer does not use all processor cores. Most often this situation occurs in laptops. To check the settings and set the correct value, you will need to do the following:

Most often, when installing an operating system that supports multi-core processors, all cores are used during operation. However, sometimes, after some failures in the OS settings, the number of used cores may change, or after replacing the BIOS battery, multi-core support may be reset and only one of them will be used. However, not all users know how to use them all again. Therefore, below we will consider detailed instructions on how to enable all kernels on Windows 7 and Windows 10.

There are two main ways to solve the problem under consideration. Let's look at each of them step by step using Windows 7 as an example. In the tenth version everything will be exactly the same.

Enabling through settings

In this method, the change occurs through the operating system configuration tools.

1. To do this, press the keyboard shortcut Win+R. As a result, the following dialog box will appear:

1. Next, enter the line “msconfig” and click the “OK” button:

1. In the window that opens by clicking, go to the “Download” tab and click the “Advanced options...” button:

1. Next, in the new window, check the “Number of processors” option, select the number we need from the drop-down list, and then click the “OK” button:

1. Next, in the parent windows, also click the “Apply” and “OK” buttons, and then restart the computer for the changes to take effect.

Enable via BIOS

BIOS is a software shell built into the motherboard that allows you to manage the hardware settings of your personal computer. This shell also allows you to use more cores. To implement the task in question using this method and enable all kernels on Windows 7 or Windows 10, you will first need to restart the PC and enter this by pressing the DEL, F1, ESC or any other button that will be shown on the initial boot screen.

After you get into the BIOS, you need to go to the “Overclocking” tab (it may also have another name “OC Tweaker”), click on the “CPU Active core control” option and select the number of cores used:

How to find out how many cores a processor has?

If you do not know how many physical cores are inside your processor, then you will first need to find out its brand and model (labeling). To do this you need to press the hotkey combination Win+Break/Pause or go to the Start menu -> Control Panel -> System.

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 overclocking the processor occurs 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 select 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 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

By default, Windows 10 uses all processor cores as needed. But other users can change OS or BIOS settings without your knowledge. As a result, the performance of the CPU and the PC as a whole decreases. In this article we will look at how to enable all cores on Windows 10.

How a multi-core processor works

All modern processors are multi-core. This technology is advantageous in that several calculations can occur in parallel, thereby increasing overall performance.

Windows 10 is highly optimized for multi-core processors. That is, the user does not need to make settings or enable all available cores. The system itself determines which resources to use for a particular task.

If you need to use one core to solve a problem, then only that core will work. As the number of calculations increases, the OS will connect the second, third core, and so on, until the calculations are completed in full.

Determining the number of working cores

To find out the number of working cores, you need. Visit the Performance tab. The image shows a processor from Intel. Below we see its condition and characteristics. This processor has 2 activated cores and 4 logical processors.

It also displays a graph of CPU activity. To make sure that all cores are active, right-click on the graph, point to “Edit graph”, select “Logical processors”.

As a result, the graph is divided into 4 subgraphs (yours may differ). Here you can see that all 4 logical cores are involved, the load of which is managed by Windows 10.

If kernels are disabled in the OS or BIOS, they will not be reflected in the task manager and even special programs such as CPU-Z. For example, by disabling two logical cores for a processor model (in the picture below), the task manager will display one core and two logical processors. That is, according to the task manager, you can call a dual-core processor single-core, although this is not so.

But at the same time, in the “Processors” section, the real number of logical processors is reflected (you can also find out similar information on the manufacturer’s website). Compare this number with the number of running logical processors in the task manager.

If the values ​​are equal, then everything is in order. If the values ​​are different, it means not all cores are activated, read below how to enable them.

Enabling all cores using Windows 10

The method involves changing the system configuration settings. Open Run (described). Type msconfig into the input line, click OK.

Visit the Downloads tab by clicking More Options. To run all processor cores on Windows 10, uncheck the “Number of processors” option as well as the “Maximum memory” option. Click OK in all windows. Restart your PC. If these options are not checked, move on to the next method.

Now go to the task manager and enjoy the result. If you enable all cores, PC performance will significantly increase.

Activating all cores in BIOS

BIOS contains PC hardware settings. There are different ones, and their section names are different. Let's look at activating all cores, using AMI as an example, and then list the names of the necessary settings.

You need . Go to the OC Tweaker section. Next, point to the CPU Active Core Control option and press Enter. Select Disable by pressing Enter.

Don't forget to press F10 and select OK to save the settings. As a result, all cores will be turned on (unlocked).

Other sections may be called Advanced, Extreme Tweaker, and similar ones. The options themselves can have the following names: Processor Options, AMD Core Select, Processor Core, Active Processor Cores, Core Multi-Processing, CPU Cores and similar ones. These options are enabled by All, Enable (Disable), All Cores. The UEFI settings are changed using the same principle.

As you can see, there is no need to activate all processor cores on Windows 10. By default, the system itself determines how much CPU power to use to solve the assigned tasks. Well, if another user has limited the number of working cores, you can always correct the situation thanks to our recommendations.

Today there are computers whose computing power will surprise few people. 4- or 6-core PCs and laptops do not surprise people, but there are also newcomers to this field who are interested in everything and want to know as much information as possible. Today we will look at an interesting question: how to enable all cores on a Windows 10 computer to increase its performance.

If you want to find out, you can find out, for example, using programs, a computer manual, or standard Windows capabilities. Now let's look at all the possible ways.

How many cores are on the computer

CPU Manual

If you have documents for your computer, then information about the cores can be found there, in the section on the CPU. You can do the same on the Internet by entering the model of your processor and see all the necessary characteristics.

Information about the CPU can be viewed by going to the corresponding menu. To do this, right-click on the Start menu and select "System", look at the block "System". But only the processor model is shown there; the rest will have to be looked for somewhere else.

Windows 10 Tools

Let's open the device manager. This can be done by entering in the search field "device Manager".

Finding the tab "Processors" and open it. The number of points there are, the number of cores on your processor.

Special utilities

Now let's look at several third-party programs that will help us determine the number of cores in the processor.

CPU-Z

A useful and free program, CPU-Z displays many characteristics of a computer, or rather, its components. It is easy and not demanding.

In order to view information about the cores, go to the CPU tab and look at the line "number of active cores".

I have mentioned this program more than once in my articles. It contains a complete set of information about all computer components.

Download the program, run it, then go to the tab "Motherboard", Further "CPU". Block "Multi CPU" shows us the number of cores.

In the same program, you can go to the tab "Computer", Then "Summary information" in the block "Motherboard" click on the name of the processor, where the line "CPU type".

How many cores are used by the processor

Some people think that not all cores work in a multi-core computer; in fact, this is not the case; they all work always, but at different frequencies.

The fact is that with a large number of cores, only the work is optimized, that is, the data is processed faster. One more thing. If the program is not optimized for several cores, then no matter how many there are in the computer, the program will still only use a certain number.

How to enable all cores of a computer or laptop

No way. The kernels on all modern computers always work without restrictions. Why should developers limit the processor and memory, especially when running Windows.

Please note that if the checkboxes in the MSConfig utility, which is described below, are turned off, this means that there are no restrictions. But you can do it yourself, since this utility is designed for testing software.

Even if you now try to change the settings to maximum, nothing will change; you can see this for yourself using the instructions below.

Everything is simple here, follow these instructions:

• Click Win+R and enter in the window msconfig
• , then go to "Extra options".
• Put a tick on "Number of processors" And "Maximum Memory", uncheck the remaining boxes.
• In the “Maximum memory” item, indicate the maximum value.

Once done, save the changes and restart your computer.

Enable all cores using BIOS

Everything is a little more complicated here. It’s worth going in only if your computer is unstable. If no glitches or slowdowns are noticed, then everything is fine and the kernels are usually turned on automatically.

If you decide to try to enable kernels through the BIOS, then you need to go to the section Advanced Clock Calibration and set the value "All Cores", or "Auto".

The difficulty here is that in different versions of motherboards and laptops, the sections in the BIOS are called differently, so I can’t say exactly where to go.

Thus, we looked at how to look at the processor cores, how to use all cores to reduce computer boot time, and the uselessness of this action.))
