How to enable all kernels on Windows 7: the simplest solutions

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

What gives the inclusion of all the cores of the processor

Many users about the system's use of all the processor cores have a rather distorted view. Remember, you can enable two or four cores, but it's not the same thing as using two or four processors! The performance increase will not be the same as expected.

Transmission or reading of data will be faster, but the amount of information processed will remain the same. To understand why and how to include all the kernels on Windows 7 (and, in general, whether it is worth doing), we will make some analogy with the reception of food. It goes without saying that you can put food in your mouth with one hand, or two. In this case, the hands are the core of the processor. It is clear that using both hands the process will go much faster. But the trouble is: when the mouth is full, no hands, be they at least four, even six, will not help. Food will simply have nowhere to put.

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 kernel occurs, but the total volume remains the same, and above this index, as they say, you will not jump.

How to enable all processor cores on Windows 7 when changing BIOS settings

So, to begin with, consider the most unpleasant situation, when for some reason the BIOS has been changed parameters, there was a reset settings or the system just "flew away."

In this case, when deciding how to include all the kernels on Windows 7, you need to build on the specific settings. For this purpose, a section called "Advanced Clock Calibration" is used, where the default value is "Auto" or "All Cores" (in different BIOS versions, the partition names 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 the cores of the processor will be used automatically.

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

However, even if the BIOS settings are set up correctly, and the processor cores are still not used, you can use your own operating system tools.

How do I enable all kernels on Windows 7 in this situation? Then you need to call the "Run" menu and register there the "msconfig" command to enter the configuration parameters. Here we have the "Download" tab. Below the main window there is a button for additional parameters. Clicking on it, we get to the setup menu.

On the left we use the number of processors row and select the number corresponding to the number of cores (drop-down list). You can not worry, more than they actually are, the system will not display. For example, we need to solve the problem of how to include 4 cores on Windows 7. As already clear, from the list we choose this number. After the changes are made, we save the configuration and restart the computer.

But here there are their pitfalls. With such operations you need to be very careful. It is important to know that each kernel should have at least 1 GB (1024 MB) of RAM. If the indicator of the bars "RAM" does not correspond to the required values, there is nothing to try. So you can only get the opposite effect. In this case it is a question of stationary computers of manual assembly. Laptops (if the equipment did not change) this does not threaten, since any manufacturer takes into account the possibility of using all the cores of the processor system. Pay attention, because for 2-core processors, as a rule, there corresponds at least 2 GB of RAM, 4-core processors - at least 4 GB, etc.

The debug and lock points for PCI should be disabled.

Instead of an afterword

So we figured out how to include all the cores of the processor of Windows 7. In general, as it is already clear, this process does not cause special difficulties in Windows 7 and above. Another thing is that you need to analyze the configuration of the system in advance to see if the number of cores and memory slots match, because as a result there may be a complete slowdown of the computer or, in general, its failure. So with such settings it's better not to joke, if there is no firm belief that the inclusion of absolutely all the cores is an absolute necessity.

However, with the BIOS there should be no problems. Most systems, when resetting values to default parameters, imply maximum utilization of the capabilities of modern multi-core processors. Such a decision was made, so to speak, in the extreme case.
