How to run the game with the right number of cores. Two Computer Optimization Myths That Will Never Die
Owners of powerful computer systems based on multi-core processors, of course, are trying to "squeeze" everything possible out of them in terms of increasing the performance of machines running, for example, running windows 7 or the like. But far from everyone knows how to enable the kernels on the "computer". windows 7, as well as newer systems, offers a universal solution, which will be discussed below.
What gives the inclusion of all processor cores
Many users have a rather distorted opinion about the use of all processor cores by the system. 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 turn on all the cores on windows 7 (and, in general, is it worth it), let's draw some analogy with eating. It goes without saying that you can put food in your mouth with one hand, or with two. IN this case hands are processor cores. It is clear that when using both hands, the process will go much faster. But here's the problem: when the mouth is full, no hands, whether there are at least four or six of them, will not help. There will simply be nowhere to put food.
Exactly the same is happening with the computing capabilities of multi-core processors. 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 above this indicator.
How to enable all processor cores on windows 7 when changing BIOS settings
So, to begin with, let's consider the most unflattering situation, when for some reason changes were made to the BIOS settings, settings were reset, or the system simply crashed.
In this case, when deciding how to enable all cores on windows 7, you need to start from specific settings. For this, a section called "Advanced Clock Calibration" is used, where the default value should be "Auto" or "All Cores" (in different BIOS versions, the names of the sections may differ or be in tabs with other parameters).
After applying the changed settings, you will only need to reboot the system. In theory, if there are no failures in the BIOS itself, all processor cores will be activated 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 involved, you can use your own tools of the "OS" itself.
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 is the tab we need "Download". Just below the main window is a button for additional options. By clicking on it, we get into the settings menu.
On the left, use the line for the number of processors and select the number corresponding to the number of cores (drop-down list). You don’t have to worry, more than they actually are, the system will not display. For example, we need to solve the problem of how to enable 4 cores on windows 7. As it is already clear, we select this number from the list. After the changes are made, save the configuration and restart the computer.
But there are pitfalls here. With such operations, you need to be very careful. It is important to know that when enabled, each core must have at least 1 GB (1024 MB) random access memory. If the indicator of the “RAM” bars does not correspond to the required values, there is nothing to try. So you can only get the opposite effect. In this case we are talking about desktop computers hand assembled. Notebooks (if the equipment has not changed) are not threatened, since any manufacturer takes into account the possibility of using all the cores of the processor system. Please note that for 2-core processors, as a rule, it corresponds to at least 2 GB of “RAM”, for 4-core processors - at least 4 GB, etc.
The debugging and PCI blocking items must be disabled without fail.
Instead of an afterword
So we figured out how to enable all the cores of the windows 7 processor. In general, as it is already clear, this process in windows 7 and above does not cause any particular difficulties. Another thing is that you need to analyze the system configuration in advance to match the number of cores and RAM slots, because as a result, a complete slowdown of the computer or, in general, its failure may occur. So it’s better not to joke with such settings unless you are absolutely sure that turning on absolutely all cores is an absolute necessity.
However, there should be no problems with the BIOS either. Most systems, when resetting to default settings, assume the maximum use of the capabilities of modern multi-core processors. Such a decision was given, so to speak, as a last resort.

Parallelism is not a luxury, but a means of acceleration, so how to enable all cores on windows 7?
Gone are the days when a multi-core processor was considered something out of the ordinary, and the owners of such computers could be counted on the fingers. Today, even the most seedy, budget laptop has at least a couple of cores in the processor. What does this mean in practice? The fact that the work, almost continuously performed by a computing device, has become possible to shift to the shoulders of two or more workers.
Even the most insignificant actions of the user bring to life a huge sequence of instructions in the processor. If some of them can be executed on one core, and some on another, then the overall performance of the computer will increase dramatically. Potentially, windows supports all available kernels, but in practice this option usually needs to be activated first. Read below to learn how to enable all processor capabilities on a computer running windows 7.
Like any other modern operating system, windows positions itself as a multitasking system. Before the advent of the era of multi-core processors, multitasking was something of a convention. From the user's point of view, it looked like several processes were actually running on the computer screen at once. In fact, the system simply distributed time between windows, alternately making one or another task active. Even two cores in the system turn multitasking from fiction into reality.
Loading at system startup
Turning on the computer and starting windows does not mean enabling multitasking. In order for this to happen when the computer is turned on, you need to make some settings in windows. This can be very helpful in improving overall performance. Everyone who uses a computer for games or work will immediately feel the positive effect of this procedure. To solve this problem, windows offers the user all the necessary tools. The setup procedure is extremely simple.
In order to enable all the processor cores to work, you do not need to go into the registry or perform other complex manipulations.
Buyers of new powerful laptops do not even suspect that all its power may be unused if this is not specifically taken care of. Having many cores to work on one - this situation is reminiscent of a story about money thrown away. It is necessary to enable the processor cores immediately after the system starts. So, to business.
From words to deeds
To use the full power of the processor in windows and enable multitasking at startup, you need to take a few very simple steps:
- Press the "Win" + "R" keys to access the "Run" window.
- In the window that appears, type in the msconfig command.
- As a result, a configuration window opens in front of us. Windows systems. To enable all computing power, go to the second tab called "Download".
- Click on the "Advanced Options" button and we get another window - the window for fine-tuning windows activation.
- It remains only to indicate the actual number of cores in the system in the drop-down list.
Then click on "OK", reboot and enjoy the result - windows should work much faster. To do all the described manipulations means to turn on the second wind of your system. And it will become much more convenient to work and play, and many tasks that were previously performed with a scratch will now be solved in an instant.
According to experts, multi-core Intel processors provide maximum performance in most tests. Their power is enough to turn a home or laptop computer into what used to be classified as a high-performance server. It remains only to fantasize about what chip developers are preparing for us in the coming years.

[instruction] How to enable all cores on windows 7!? (2017)
How to enable all kernels on windows 7? This question is often asked by users whose computers are slow and freeze periodically.
Even on multi-core devices, stuttering can occur. Let's take a closer look at how to effectively speed up your PC and "force" the system to use all available cores to the fullest.
Modern computers are multi-core devices. However, no operating system uses all the cores to their full capacity. Such a limitation is necessary to save the resources of PCs and laptops.
Modern hardware technologies allow you to "load" the required number of cores in the process of working with certain programs that require more performance.
If your PC does not start up faster even when a powerful photo editor, game or editing program is running, you need to adjust the processor usage mode yourself.
This configuration option is one of the simplest and most effective. The bottom line - the overclocking of the processor occurs immediately during the startup of the OS. The user can always change the settings and return the original parameters.
Follow instructions:
- Open the command window using the Win and R keyboard shortcut;
- In the text field of the window that opens, type in the msconfig system configuration command;
Rice. 1 - call 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 download options;
- Press the advanced options key;
Rice. 2 - Windows configuration window
- In the tab that opens, the mode of using the available computing characteristics of your PC is set. Check the boxes next to the number of processors and the maximum amount of memory. These lines were previously inactive because the computer was in resource-saving mode;
- Choose the highest number of cores and the maximum amount of available memory;
Rice. 3 - setting boot options
After turning on the computer again, the multitasking mode is activated. The user can also select fewer processors and memory. The optimal number for fast work- 5-6 cores and 1024 MB of memory for each processor.

Another option for setting the speed of the OS is to set new settings in the BIOS. This option allows not only to increase the efficiency of task execution, but also prevents failures that have occurred in the OS and the regular occurrence of blue screen.
First we need to go into the BIOS. Most desktop computers and laptops start the I/O system in the same way. It is enough just to turn on the PC and in the first 5 seconds after pressing the "Power" key, click on the Escape, F5, F2, or F1 button. The bottom left corner of the screen indicates which button to press.
Next, the BIOS will start. In some cases, switching on may take longer than one minute. Management in the window that opens is carried out using the four directional arrow keys. The choice is pressing Enter.
Appearance, the location of the tabs and their sequence may vary. It all depends on the PC manufacturer and BIOS modification. To set up multitasking, follow the instructions:
- Open the Clock Calibration section, as shown in the figure below;
Rice. 4 - calibration of the use of cores in BIOS
- Using the left and right arrows on your keyboard, set the "All Cores" option. Thus, the laptop will use all available cores at the same frequency;
- Save your changes and exit the BIOS window.
- Wait for windows 7 to turn on.
You can also activate the work of all cores using third-party programs. They require minimal user intervention, have a simple and intuitive interface. One of the popular utilities is CPU-Z.
The program allows you to carry out a comprehensive configuration of hardware and software components:
- Processor;
- Cash;
- 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 - the main window of the CPU-Z application
After making changes, press the "OK" button. Turn off the program and restart the device.
Many inexperienced PC or laptop users are wondering how to turn on all the cores of the device when applications that are difficult to implement fail.
How to enable the second processor core: instructions
As a rule, the second processor core is disabled to save electricity. To enable it, you need to refer to the commands in the Start menu.
- From the Start menu, select Run. In the window that appears, enter the "msconfig" command. Alternatively, you can use the keyboard shortcut "Win" and "R" to bring up the "Run" window.
- In the window that appears, go to the "Download" tab. A list will open where you need to select the operating system you are using (if more than one is installed on the computer). Now click on the "More Options" button.
- You will see the item "Number of processors". Check the box next to it, and from the drop-down menu, select the number "2". In addition, pay attention to the "Debug" and "PCI Balancing" items. You need to make sure that there are no checkboxes for these functions.
- Now click "OK" and then "Apply".
- Close all windows and running programs. save everything unsaved documents. Enter the Start menu and restart your computer.
- After the reboot, open the task manager, which can be called up using the keyboard shortcut "Ctrl + Alt + Del". In the manager, open the "Performance" tab.
- In case the 2nd core is connected, you will be able to observe two independent "CPU Load History" graphs.
- For finer control over the operation of the processor, you can assign different cores for the operation of certain programs. To do this, refer to the "Processes" tab and by right-clicking on desired program, select Set Match.
- After that, you will have the opportunity to choose the work of one or another kernel (or all together) to serve a particular application.
In a similar way, you can turn on all the processor cores.
Gone are the days when a multi-core processor was considered something out of the ordinary, and the owners of such computers could be counted on the fingers. Today, even the most seedy, budget laptop has at least a couple of cores in the processor. What does this mean in practice?

And it will become much more convenient to work and play, and many tasks that were previously performed with a scratch will now be solved in an instant.
Computer performance depends on many things. One of them is the number of cores in the processor. But not always all available cores are involved. Perhaps they are, but they are idle.
What is the effect of multi-core
The processor core serves as a computing machine. It is it that performs most of the tasks assigned by the user.
If the core is one, then only it performs all the functions, which leads to the formation of a queue. For example, the queue is noticeable when you start several programs, and they open one after another, and not at the same time. This means that the kernel first starts one application, and then starts the second one.
But if the processor has two, four, six cores, then existing tasks are distributed between them, which reduces the number of requests queued for execution. For example, if you run two programs on a dual-core processor, then one core will start one application, and the second one will start another.
Not all programs support the division of tasks into cores, but every year there are more and more of them. By the way, Windows is 32 and 64-bit, that is, the version operating system for a single-core and dual-core processor is different.
So, the number of cores ultimately affects the speed of tasks: the more cores, the sooner they will do everything that is required of them.
How to find out the number of cores
Before enabling additional cores, you need to find out if the processor has them. Firstly, information about the processor is presented in the instructions for it or on the official website of the manufacturer. To find out the processor model, follow these steps:
- Expand system settings.
Open system settings
- Go to the "System" block.
Open the "System" block
- Open the sub-item "About the system" and find the line "Processor". It contains the name of the model and some information about it.
Find the line "Processor" in the "About" tab
Secondly, information can be found through system settings and third-party programs.
Through the "Device Manager"
To find out the number of processor cores through the "Device Manager", follow these steps:
Video: how to find out the number of cores using the "Device Manager"
Via CPU-Z
CPU Z- free utility providing detailed information about the computer. On its main page "CPU" is the line "Number of active cores", which indicates the number of available cores.
Look at the line Cores in the CPU-Z utility to find out the number of processor cores
Via AIDA64
AIDA64 also has free version program that you can use. Having opened it, go to the item "System board" - "CPU". Find the Multi CPU block and count how many cores are described in it.
Look at the Multi CPU block for the number of cores
Through Everest
Another one free program, which allows you to find out the number of processor cores. To do this, you need to run it and go to the item "Motherboard" - "CPU" - the Multi CPU block.
Expand the CPU tab and pay attention to the Multi CPU block to see the number of cores
Activation of nuclei
If you are convinced that not all processor cores are involved, it's time to activate them. It can be done different ways, one of them won't even require a login.
Using system settings
Do the following:
- Expand the "Run" window by holding the Win + R combination, and then write the msconfig command in it.
Run the msconfig command to open "System Configuration"
- In the window that opens, go to the "Download" tab and open additional options.
Click on the "Advanced Options" button
- Specify the maximum value for the "Number of Cores" and "Maximum Memory" blocks. Uncheck PCI blocking and debugging. Save your changes and restart your computer for the changes to take effect.
Specify the desired number of cores and memory
If the system starts to work incorrectly, return to the parameters and set the memory value below the maximum.
Please note that the minimum amount of memory for one core is 1024 MB. If a value below this is used, then the computer will only start to run slower, no matter how many cores are used.
Video: how to activate kernels using system settings
Using BIOS settings
If you do not have access to the system, then you can activate the kernels in the BIOS:
Video: How to enable unused cores using the BIOS
Nuclear deactivation
If for some reason you need to disable the use of extra cores, you must follow the same steps as described above in the Activating Cores instruction, but set not the maximum number of cores, but the one you need.
Disabling all cores will not work. At least one must work, otherwise there will simply be no one to manage the operation of the system.
What to do if the computer does not see all the cores
If you are sure that the computer is showing you an inaccurate number of cores, then first go to the msconfig settings and uncheck all the checkboxes in the advanced boot options. Restart your computer and check if that got rid of the problem for you.
Uncheck advanced boot options
After that, check if the Advanced Clock Calibration item in the BIOS is set to All Cores or Auto. The CPU Core Control item must be set to Automatic Mode.
Set to Automatic Mode
The system may not have installed the drivers for the processor correctly. You will have to reinstall them manually:
Select the processor and click on the "Update Drivers" button
Drivers can be updated automatically via Intel® Driver & Support Assistant
Select the method "Search for drivers on this computer"
There are cases when a similar error occurred after upgrading to new version operating system. In such situations, it is necessary to install / reinstall the system from scratch in order to get rid of the error.
Video: what to do if the computer does not see all the cores
So, if you have the opportunity to use more cores than are currently active, do it. But keep in mind that this will require a sufficient amount of RAM. Kernels can be activated through system settings or BIOS.
Even on a multi-core computer in Windows 7, by default, only one core is used when the system is turned on. This significantly reduces the PC boot speed. Let's see how you can include all of these objects to speed up your work.
Unfortunately, in Windows 7 there is only one way to activate the kernels. It is executed through the shell "System configuration". We will consider it in detail below.
"System configuration"
First we need to activate the tool "System configuration".
- Clicking "Start". We go to "Control Panel".
- Go to directory "System and safety".
- Clicking "Administration".
- In the list of elements of the displayed window, select "System configuration".
There is also more fast way activation of the specified tool. But it is less intuitive, as it requires you to remember one command. Recruiting Win+R and drive into the opened area:
Click OK.
- The shell of the tool needed for our purposes opens. Let's go to the section.
- In the area that opens, click on the element "Extra options…".
- An additional options window will open. It is here that the settings of interest to us are performed.
- Check the box next to the option "Number of Processors".
- After that, the dropdown list below becomes active. It should select the option with the maximum number. It is it that reflects the number of cores on a given PC, that is, if you select the largest number, then all the cores will be used. Then press OK.
- Returning to the main window, click "Apply" And OK.
- A dialog box will open asking you to restart your PC. The fact is that the changes that were introduced in the shell "System Configurations", will become relevant only after rebooting the OS. So keep everything open documents and close active programs to avoid data loss. Then click .
- The computer will restart, after which all its cores will be enabled.
As you can see from the above instructions, activating all the cores on a PC is quite simple. But in Windows 7, this can only be done in one way - through the window "System Configurations".
