How to connect all processor cores in Windows 7. Managing processor cores on a computer - programs and built-in system tools

Many inexperienced users A PC or laptop wonders how to enable all the cores of the device when complex applications 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 access the commands in the Start menu.

From the Start menu, select Run. In the window that appears, enter the command "msconfig". Alternatively, you can use the Win + R key combination 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 there are several installed on your computer). Now click on the " Additional options".
You will see the "Number of processors" item. Check the box next to it, and select the number “2” from the drop-down menu. Also, pay attention to the "Debugging" and "PCI Balancing" items. You need to make sure that there are no checkmarks on these functions.
Now click "Ok" and then "Apply".
Close all windows and running programs. Save everything unsaved documents. Go to the Start menu and restart your computer.
After the reboot, open the task manager, which can be accessed using the keyboard shortcut "Ctrl+Alt+Del". In the manager, open the "Performance" tab.
If the 2nd core is connected, you will be able to observe two independent graphs of the “CPU Load History”.
For finer control of the processor's operation, you can assign different cores to run certain programs. To do this, go to the "Processes" tab and right-click on the desired program, select "Set Match".
After this, you will have the opportunity to select the operation of one or another kernel (or all of them together) to serve a specific application.

In a similar way, you can enable all processor cores.

Since the original technology Windows operation in terms of the computing capabilities of the processor, it assumes the use of only one processor core, and if there is a shortage of the rest, many owners computer systems based on multi-core processors It's quite natural to wonder how to enable additional kernels on Windows 7 or any other system. But the very essence of the question comes down to what kind of performance effect using all the cores can give, and in general, is it worth doing such things. Let's try to figure it out.

What does enabling all processor cores do?

A processor is a device that has disabilities in terms of calculations. It has limitations or, if you like, a certain ceiling on the number of operations performed. That is, even if it has at least 4 or 8 cores, it will not jump above its capabilities. This means that no matter how fast data is transferred to it, its volume for processing will always remain the same. In some ways this is akin to even downloading RAM.

Before deciding how to enable all kernels on Windows 7, you need to clearly understand how it all works. You can compare this, for example, with eating. You can operate with one hand or two. In this example, the mouth (or stomach) can be compared to the processor and the hands to the nuclei. Putting several pieces of cake into your mouth with one hand will be slower, with two - faster. But this does not mean that the mouth will fit more than as much as it is designed for. Same with processors. Accelerating the loading of computational operations into the processor does not always contribute to their speedy execution. And information processing can be compared not only to chewing food, but also to swallowing. It’s clear that you won’t be able to swallow more than what’s allowed.

However, if you can chew fast enough, similar to modern processors that are able to “swallow” information, why not?

Is this really necessary?

How advisable it is to do this is up to everyone to decide for themselves. But when deciding how to enable a second core on Windows 7, provided you have a 2-core processor, it is worth considering several points.

It is unlikely that a significant increase in performance will be achieved, 10-15% (although for some systems or resource-intensive programs this is a fairly significant indicator). But the problem is that the use of each core is tied to the amount of RAM. But here problems can arise, because when commands are redirected to each processor core, RAM may overflow, and the entire system will simply hang.

How to enable all cores on Windows 7 via BIOS?

But if the decision to turn on all cores is made, you should first pay attention to the settings of the primary BIOS systems. Initially, the activation, regardless of the software environment of the installed operating system, must be done there.

After logging in, you should find a section with a name like Advanced Clock Calibration. On most systems, the default is Auto. This means that additional cores will only be used if the main core cannot handle the operations. There is nothing simpler than setting the All Cores value, which will correspond to the use of all processor cores, regardless of the number and type of operations being performed.

Accessing settings via system configuration

Now let's pay attention to how to enable all kernels on Windows 7 in software environment the system itself. Some users make the mistake of thinking that such actions can be performed in the standard “Control Panel”. Nothing of the kind! You will have to use the “Run” console or in the English version of the system - Run (Win + R). In it you need to enter the msconfig command (a unified tool for accessing Windows configuration for all systems), go to the boot tab, and then click on the button to configure additional settings.

Now, actually, about how to enable all cores on Windows 7. In the new window on the left, the number of cores is set, which corresponds to the number of processors, and on the right, the required amount of RAM is set.

Mandatory conditions and parameters

With RAM, things are not so simple. Although the system itself determines the amount of memory allocated to each core, seemingly automatically, you should not delude yourself on this score.

It is generally accepted, according to established standards, that 2 GB of RAM corresponds to 2-core processors, 4 GB corresponds to 4-core processors, etc. But even here, not everything is so simple. Each core must be allocated at least 1 GB of RAM. If the computer system configuration does not meet the established requirements, you don’t even have to try to make any settings (nothing will work anyway).

On the other hand, in the question of how to enable all kernels on Windows 7, one should not lose sight of the fact that modern processors have capabilities higher than stated. So, for example, Intel processors The second generation Core i7 installed in laptops, in terms of computing processing, corresponds to 4-core processors in stationary systems. Therefore, it should not be surprising that with 8 GB of RAM the memory will be allocated differently (given two threads). The value for the number of processors will indicate 4 (although there is actually one with two dual-threaded cores) with the corresponding memory allocation.

Instead of a total

Finally, in conclusion, it is worth asking yourself whether such adjustments are worth pursuing. In general, if a system with a large enough amount of RAM and powerful processor shows no signs of inhibition, system settings in this regard, it is better not to touch, otherwise you can even achieve the completely opposite effect when, due to too fast loading data, the processor simply will not cope with such volumes of calculations, despite the use of all cores. As you might have already guessed, this requires fine tuning, and not everyone can do this. Overlockers can overclock processors, but this is also fraught with some negative consequences for processors in terms of physical failure.

Optimizing cores and memory using MSConfig

The advice is based on the assumption that Windows does not use all the processor cores and megabytes of RAM at boot. Allegedly, you need to specify the required amount so that the computer turns on faster using a “secret” setting.

It's done like this: Start - Run(Windows 10 has a search field instead of Execute) - msconfig - OK.

The program will start System Configuration(msconfig.exe). Tab :

You need to press Additional options to open Windows boot options:

Bye crazy hands We haven’t gotten to the settings, nothing will be indicated here, no checkboxes will be ticked. Why would Windows developers limit system performance?

But people who are not familiar with critical thinking think differently: initially the checkbox is not checked, so the restriction is enabled. Allegedly, the absence of checkboxes prevents the operating system from knowing how many cores the processor has and how much RAM is installed. And supposedly you need to specify manually:

And after rebooting, the computer will begin to use all resources.

There are several options for this advice. I went through sites dedicated to Windows optimization by selecting several.

For example, a certain Yuri believes that the default is to boot from one core:

Others remember RAM. “PC Master Blog” claims that she has the same problem.

The beginning of the council

I cut off some of the text so it wouldn't long screenshot, but it is also clear that the author knows nothing either about the stages of loading the operating system, or, in principle, about how modern computing devices work. Here's what he advises next:

Here it is advised to specify not only the number of cores, but also the memory size. And in the end they say that it is possibletake off tick.

Where is the logic? An option is installed and then disabled, how can this affect anything in principle?

Where does the myth come from? I believe this is not only a matter of ignorance of the advisers’ equipment, but also the ambiguous official help for MSConfig. Check out the article MSConfig the System Configuration Tool on the official Microsoft website. The description of the options really leaves room for speculation if you don't know the context:

Translation: “If you click on Advanced Options (on any OS), you can set options such as the number of processors allocated to the operating system at boot or the maximum amount of RAM. (As a rule, usually not noted).”

The text does not contradict the myth: it is indeed possible to specify how many processors and RAM to use at boot. But these options are not intended to improve performance.

Actually Windows Always uses All processors and processor cores and all RAM. No one thought to limit the system, especially during boot.

Options in msconfig are needed by programmers to test programs so that limit available PC resources.

How crazy is it to say that Windows does not use all possible resources when booting the computer? After all, in the interests Windows developers make sure the computer turns on as quickly as possible. Imposing restrictions is stupid.

Some "geniuses" are trying to prove that the "Number of processors" option speeds up the computer, because when set to 1 games start to slow down. There is no logic to be found in this. When the per-core limit is enabled, performance decreases (this is especially noticeable in games), but by default restrictions are disabled and programs are free to use all the cores as they please.

Fortunately, this advice is harmless. Installation maximum values does not affect the operation of the computer in any way, because the result is the same as with the settings turned off. That's when you add RAM to your computer or install a processor with a large number kernels, you will have to change the settings to maximum again in msconfig.

Make the game use all CPU cores

The next myth is more difficult to explain. The fact is that programs do not work at all as it seems to PC users. The work of software with processor cores and multiprocessor systems is the topic of books that are of no interest to non-programmers.

So people just look at the CPU consumption in the Task Manager and engage in pointless attempts to optimize something. For example, they try to adjust parameters like previous setting so that their favorite program loads 100% of all processor cores.

This is akin to using phone cases to protect your body from harmful radiation. People who know physics will only twirl their finger at their temples, while others buy cases in packs and recommend them to their friends.

But let's return to running programs on multi-core processors. A crazy idea arose on the border of knowledge and ignorance use the program CPU Control to assign all cores to games.

The council met ten years ago. For example, when discussing the game Gothic 3:

In the screenshot above the user s063r I thought that the game did not use the second processor core. Encryption answered that you need to use CPU program Control.

What kind of miracle beast is this? who gets into program code and forces the program to change the logic of its work? This is what the utility looks like:

Seeing this miracle Yudo, I grabbed my head: how could stupid the developers did, making it so that at startup everything running programs are automatically “assigned” to the first processor core!

See the "CPU" column when running CPU Control:

One and three zeros mean that only the first processor core is assigned to the program. And it happens after launch most utility. What to launch the situation was different, with using the CPU Control cannot be seen. You can, of course, launch the Task Manager before all the manipulations and look at the assignments of processes to cores, but who these days thinks critically and checks the operation of programs?

False advice goes like this: programs run on only one core, which can be verified by running CPU Control. And there you can assign the program to use all processor cores.

This is like shooting yourself in the foot and applying bandages to treat it. Or maybe you just don’t need to shoot at all and everything will be fine?

The myth is very tenacious because Sometimes it helps: if the running software heavily loads the processor (most often these are viruses), assigning it to only one core limits the resources available to the malware and allows the remaining processor cores to work for the benefit of the game. But this is treating the symptom, not solving the problem.

In fact, before the launch of CPU Control, there were no per-core limits. The program installs it at startup. Installation separate program returns the default setting for all cores. That's all.

How should you actually configure it? But no way. Ask the authors of the program/game to rewrite their creation for multi-core systems. Not all software can use all processor cores; this cannot be influenced from the outside. Better get busy

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 similar OS. But not everyone knows how to enable kernels on a “computer”. Windows 7, as well as newer systems, offers 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 kernels on Windows 7 (and, in general, whether it’s worth doing), let’s draw an analogy with eating. It goes without saying that you can put food into your mouth with one hand, or with both. IN in this case hands are 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 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 higher than this indicator.

How to enable all processor cores 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 the section called "Advanced Clock Calibration", where the default value should be set to "Auto" or "All Cores" (in different BIOS modifications Section names may differ or be in tabs with different 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 BIOS settings turn out to be configured correctly, but 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 (drop-down list). You don’t have to worry, the system won’t display more of them 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 our own pitfalls. 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 reverse effect. In this case we are talking about desktop computers hand assembled. 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.

IN mandatory Debugging and PCI blocking items must be disabled.

Instead of an afterword

So we figured out how to enable all cores windows processor 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 the system configuration 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, with BIOS problems there shouldn't be. 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.

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 one hand. Today, even the most shabby, budget laptop has at least a couple of cores in the processor. What does this mean in practice? The fact that the work performed almost continuously by a computing device can now be transferred to the shoulders of two or more workers.

Even the most insignificant user actions trigger a huge sequence of processor instructions. If some of them can be performed on one core, and some on another, then the overall performance of the computer will increase dramatically. Potentially, Windows supports the operation of all available cores, 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 OS, Windows positions itself as a multitasking system. Before 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 task or another active. Even two cores in the system turn multitasking from fiction into reality.

Loading at system startup

Turning on your computer and starting Windows does not mean enabling multitasking. In order for this to happen when you start your computer, you need to make some settings in Windows. This can be very helpful in improving overall performance. Anyone using a computer for gaming 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 processor cores, 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 running on one - this situation is reminiscent of a story about wasted money. It is necessary to enable the processor cores immediately after the system starts. So, let's get to it.

From words to deeds

To use the full power of the processor in Windows and enable multitasking at startup, you need to do a few things: simple steps:

Press the “Win” + “R” keys to access the “Run” window.
In the window that appears, enter the msconfig command.
As a result, a configuration window opens in front of us Windows systems. To put everything into action computing power, go to the second tab called “Download”.
Click on the “Advanced parameters” button and get another window - the window fine tuning windows activation.
All that remains is to indicate the number of cores actually available in the system in the drop-down list.

Then click on “Ok”, reboot and enjoy the result - Windows should work much faster. Doing all the described manipulations means turning 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 difficulty will now be solved in an instant.

According to experts, multi-core Intel processors produce maximum performance on most tests. Their power is quite enough to transform home or laptop computer into what used to be classified as high-performance servers. We can only imagine what chip developers are preparing for us in the coming years.

[instructions] How to Enable all Kernels on Windows 7!? (2017)

How to enable all kernels on Windows 7? This question is often asked by users whose computers work slowly and periodically freeze.

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

Modern computers- These are multi-core devices. However, not a single one operating system does not use all cores on full power. Such a limitation is necessary to save resources on PCs and laptops.

Modern hardware technologies allow you to “load” the required number of cores while working with certain programs, which require more performance.

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

This setup option is one of the simplest and most effective. The bottom line is that overclocking the processor occurs immediately during OS startup. The user can always change the settings and return the original parameters.

Follow the instructions:

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

Rice. 1 – window call windows configurations

Now go to the downloads tab. Here you can view the version of the installed OS, configure safe mode and other boot options;
Click on the 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 greatest number cores and maximum amount of available memory;

Rice. 3 – setting up boot parameters

After restart computer, multitasking mode is activated. The user can also choose fewer processors and memory. Optimal number for fast work– 5-6 cores and 1024 MB of memory per processor.

Loading at system startup

Turning on your computer and starting Windows does not mean enabling multitasking. For this to happen when you start your computer, you need to make some settings in Windows.
