How to enable all processor cores in Windows 7. Using system settings. Force the game to use all CPU cores

Technologies are constantly developing and improving, and today 9 out of 10 computers have multi-core processors installed. And if dual-core processors themselves can use both cores, then in the case of four- or eight-core processors everything is not so obvious.

Often, users are not even aware of the hidden potential of their processor and do not use it on full power in games or complex programs. In our article we will tell you how to enable all kernels on Windows 10 and get full information about your processor and its capabilities.

Default number of running cores

During operation, each individual core of the computer may experience different load, which is associated with a change in the PC load profile. BIOS settings on some systems allow you to set a separate operating frequency for the cores. When the load on the PC is evenly distributed, the user will receive high performance.

If we talk about a dual-core processor, then only in one case will only one core be used - when you turn on the computer. For these purposes, the BIOS uses the resources of only one core. On the other hand, it is always possible to activate all resources to speed up even this process. On the third side, the best way to speed up loading the OS and turning on the PC is Windows installation on SSD.

Methods for enabling kernels on Windows 10

To activate all the cores of a quad-core (for example) processor when you turn on the PC, you can use:

Changing the system configuration.
Changing BIOS.

The instructions below are suitable for both 32- and 64-bit Windows 10 of all editions. Here are the necessary steps:

Note. In the “Maximum Memory” settings you need to select any numeric value not less than 1024 MB. Otherwise, your computer's boot speed may decrease altogether.

To avoid performing these steps again, in the previous “System Configuration” window, check the “Make these boot options permanent” checkbox. Confirm the actions with “Apply” and OK.

Changes via BIOS

You only need to change BIOS settings if the PC does not boot. There is no need to use this method if you do not have any basic knowledge working with BIOS / UEFI. It's better to use the previous method.

To activate all cores of a multi-core processor through the BIOS, follow these steps:

Hello, dear readers! Today we will talk about how to use all processor cores in just a couple of steps. Increasing the number of working cores directly affects the increase in computer performance. Many users, having bought a brand new computer with a multi-core processor, have no idea how to make the processor work at full capacity. But all the money was paid for. In this article we will tell you in detail how you can increase the speed of your computer by simple manipulations with the processor. This is NOT an increase in the frequency of the processor, as a result of which it may burn out or overheat (this, of course, is the case if everything is done incorrectly).

All the steps below apply to both operating system Windows 7 and Windows 8. Well, let's start. Open on the desktop command line: Win+R. To begin, enter next command: msconfig. Then click “Ok”

The System Configuration management menu will open in front of you. Here you go to the tab.

And in the section we select the maximum number. This safe way performance enhancement that will not harm your computer in any way. Click the “Ok” button and restart the computer.

Let's summarize: Well, that's all. So simple and the easy way You have learned to use all processor cores. This method can be considered one of increasing the performance of your computer.

Enabling hidden kernels

Enabling the operation of two processor cores in a computer occurs in several ways. Please note that many of them can damage your processor, so only use using software methods.

You will need

- skills of a confident PC user.

Instructions

If your computer configuration includes a dual-core processor, enable Hyper-threading in Settings. To do this, restart it, when loading, press the key responsible for entering this program. In the majority desktop computers this is Delete, in laptops – F1, F2, F8, F10, Fn+F1, Delete, Fn+Delete and other combinations depending on the model motherboard. If required, enter your login password.

Use the arrow keys to scroll through the BIOS program menu and become familiar with its interface. Find the option to enable Hyper-threading mode, it may be in the processor settings, but it may also depend on the model of your motherboard. Place a flashing cursor at its position and change the position to On using the plus/minus buttons. Exit the program, saving the changes.

If your computer has more than two cores and you only need to enable 2 of them, use special programs. Please note that they are often unreliable and only roll back changes to complete removal operating system with formatting local disk. This option is especially common when using Windows Xp on multi-core computers. The configuration of this operating system simply does not include the function of changing the number of running cores, since it was made at a time when processors were common, so rolling back changes may not be possible even if you resort to third party utilities. The only way to help here is to reinstall windows seven.

If you need to change the number of cores to make the software version compatible with the configuration, use the change the startup file attributes of this program by clicking on it right click mouse and selecting compatibility mode for XP or Vista.

note

Please note that reducing the number of working cores to two may be irreversible under Windows XP.

The second processor core is usually used by default in the operating system. Windows system XP, but some programs require you to disable it to correct operation. After this, there may be some difficulties in returning to initial settings.

You will need

- optimization program.

Instructions

Make sure the second core processor is disabled. To do this, open the manager Windows tasks by pressing the key combination Alt+Ctrl+Delete or Shift+Ctrl+Esc, then go to the system performance tab. Pay attention to how many parts the processor load window is divided into; if it is two, then both cores are enabled and functioning at the proper level.

In the case when you have only one functioning core of the two, in the Windows XP operating system, download and install an optimization program that tunes the processor. After installation, go to your computer's hardware management and enable both processor cores. IN mandatory restart the computer, even if the optimization program does not require it, do not forget to save the changes made first.

To check the operation of both cores of your computer, turn it on and launch a game or program, system requirements which they assume you have dual core processor. Launch the task manager and in the system performance viewing tab, look at the load on both elements. It may be different for them, since the load is not always distributed evenly.

Turn on the second core processor by rolling back the motherboard driver installed on your computer. Prepare the driver in advance for subsequent installation, it is best updated version. Reinstall software, then restart your computer again.

Check the functionality of both cores in Device Manager. This sequence works in very rare cases. You can also try restoring the system from an earlier state, but in this case The rest of the changes you made during the period of time will also be canceled.

Helpful advice

Make changes to the processor less often.

how to put it into work

The processor core is a silicon crystal with an area of about 10 square millimeters, on which the processor circuit, the so-called architecture, is implemented using microscopic computing elements.

Processor core device

The core is connected to the processor chip using a technology called flip-chip, which literally means a core. The technology has this name due to the method of attachment - the visible part of the core is its internal part. This ensures direct contact of the core with the cooler's radiator to improve heat transfer and prevent overheating. WITH reverse side The core contains solder bumps - bump pins that connect the die to the rest of the chip.

The core is located on a textolite base, along which pass contact tracks, connecting to the contact pads. The core itself is covered with a protective metal cover, under which it is filled with a thermal interface.

Why do we need multi-core processors?

A multi-core processor is a central microprocessor that contains two or more processing cores in a single package or on a single processor chip.

The first microprocessor was developed by Intel in 1997 and was called the Intel 4004. It ran on clock frequency 108 kHz and consisted of 2300 transistors. Over time, the requirements for computing power processors began to grow. Long time its increase occurred due to an increase in clock frequency. However, at a certain stage of microtechnology development, developers were faced with a number of physical barriers associated with approaching technological processes manufacturing to the size of the silicon atom from which the core is made.

Thus, the developers came up with the idea of creating a multi-core processor. Multi-core chips operate two or more cores simultaneously, thereby allowing for greater performance at a lower clock speed by executing two or more independent job threads in parallel.

Key benefits of multi-core processors

The main advantage of multi-core processors is the ability to distribute program work across multiple cores. This, in turn, increases the speed of programs and allows computationally intensive processes to proceed much faster.

Multi-core processors enable more efficient use of compute-intensive applications such as video editing.

In addition, computers with multi-core chips consume less electricity and make the user's work more comfortable.

Although Windows is considered the operating system for ordinary users, unlike numerous Linux distributions, still allows you to perform some operations for which experienced users they still prefer the latter. In particular, this refers to access to hardware components. The OS itself and installed drivers make sure (or at least try) that they perform at their best and provide the best user experience. First you need to know how to enable all processor cores on Windows 10 and this question We will look at it in detail in this article.

Find out quantity

If suddenly you don’t know how many there are in total and want to find out the kernel version in Windows 10 in your processor, then this is where you should start. The easiest way to do this is using Windows tools itself. Right click on the Start menu > Computer Management. In the left menu, enable Device Manager > Processor.
The number of points will indicate the number of processor cores that can be used when you know how to activate all processor cores in Windows 10.
Similar information can be obtained using third-party programs:

CPU-Z;
AIDA64;
Everest.

The first one is free, the rest cost money, but, of course, in addition to the quantity, they tell you how to watch great amount information about the computer and system, starting from the list of components and ending. Of course, they only provide information and do not know how to enable and run all processor cores in Windows 10.

How kernels generally work and how to enable them

There is a common misconception that not everyone works on a computer. This is wrong. At any moment, in addition to turning on, all of them are involved, so of course, you will never know how to disable the processor core, because it is impossible. But there is another nuance - they can work with different frequencies, being responsible for different tasks. Modern processors often equipped with several productive ones that will be launched during games, editing and other complex tasks; and simpler ones - for elementary processes. This achieves a balance of performance and energy efficiency, which is especially important for laptops. But there is no answer to the question of how to enable the second processor core in Windows 10, because they all work the same way.
It is also necessary to pay attention to the fact that in some cases it is impossible to turn on and direct the power of everyone to process a specific task. It depends solely on the software developer. Only he decides whether to unlock the cores and whether to support multithreading or not. If not, only one will carry out the greatest load and all the work, while the rest work in a gentle mode.

How to enable all processor cores on Windows 10 at startup?

There is one moment in the operation of the operating system when in fact only one thing can be active - this is the process of turning on the computer. But even in this case, the situation can be changed and you can find out how to enable 4 cores on Windows 10 using the built-in system tools and BIOS.

In the first case, you need to enable the “Run” dialog box or use the “Windows + R” hotkeys. After that, enter “msconfig” and click OK.
A window will open with basic settings systems.

Option with BIOS

The second option on how to use and configure all processor cores to work in Windows 10 is to use the BIOS. It starts when you turn on the computer using the F2 or Del keys depending on the device type.

In the BIOS itself, again, depending on its version, you need to find the item “Advanced Clock Calibration” or similar, and there enable the value “All cores” or “Auto”.

Again, it should be noted that these settings will only affect the computer startup process and will not work this way. Operation of the operating system as a whole or individual programs It depends entirely on the developers. Have they added this opportunity enable it, and how well it was optimized.

Modern computers have great computing capabilities, so surprise two-, four-, or even six-core processor someone is difficult. But a novice user who is not familiar with the technical features of the device may be interested in how to enable all cores on Windows 10 to increase computer performance.

How to find out the number of processor cores?

You can find out how many cores are in the processor installed on your computer or laptop using built-in programs Windows tools and in the description of the CPU.

In the CPU description

Check the device manual to see which model is installed on your computer. After that, find a description of the processor on the Internet.

Healthy! You can also see the model in the OS description: RMB on the Start menu → System → in the “System” block the name of the CPU is indicated.

On Windows

Programs

Many programs have been created that show the characteristics of the device.

CPU-Z

AIDA64

Shareware utility AIDA64 contains big set functions.

Run the program → Motherboard→ CPU → Multi CPU.

Alternative option: Computer → Summary information → Motherboard block → in the “CPU Type” line LMC on the processor → Product Information.

How many cores are used by default?

The main thing to remember! IN multi-core processor all cores work always and at the same time (read the article “”). They mainly operate on different frequencies(depending on BIOS settings or special utilities, which come with motherboards).

The benefits of running a multi-core CPU can be summarized as follows. If a person pours water into a bucket from one tap, he will do this work in one period of time. If you turn on the second tap, you can fill the bucket much faster, but the total volume of water that can be contained in it will not increase.

By using two taps the operation is optimized. The same thing happens when using multiple cores in the CPU - it processes the data that comes in for calculation faster and more efficiently.

Important! The processor operates in multi-threaded mode only if the program it is executing is optimized for this. If the software manufacturer does not support multi-core CPUs, only one core will be used.

How to use all cores?

On Windows 10

Important! Each core must have at least 1024 MB random access memory, otherwise you will achieve the opposite effect.

In BIOS

You can make changes to the BIOS only if they are “crashed” due to a failure in the OS (read the article “” to find out how to start a PC if it is unstable). In other cases, all processor cores are enabled automatically in the BIOS.

To enable all cores, go to the Advanced Clock Calibration section in BIOS settings. Set the indicators to “All Cores” or “Auto”.

Important! Advanced section Clock Calibration in different BIOS versions may be called differently.

Conclusion

During operation, all processor cores are used, but they operate at different frequencies (depending on the settings made). You can enable all CPU cores at OS boot in the BIOS settings or in the System Configuration options. This will reduce the boot time of your PC.
