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 far from everyone knows how to turn on the kernel on a "computer." Windows 7, as well as newer systems, offers a universal solution, which will be discussed below.
What gives 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.
Data transfer or reading will be faster, but the amount of information processed will remain the same. To understand why and how to enable all the kernels on Windows 7 (and, in general, is it worth it), let us draw a certain analogy with eating. It goes without saying that you can put food in your mouth with one hand, or with two. In this case, the hands are the processor cores. It is clear that with both hands the process will go much faster. But the trouble is: when the mouth is full, no hands, be they at least four, at least six, will not help. There’s just nowhere to put food.
The exact same thing is happening with the computing capabilities of multi-core processors. Here, only the optimization of the number of operations performed by each core in a certain period of time takes place, but the total volume remains the same, and, as they say, you will not jump above this indicator.
How to enable all processor cores on Windows 7 when changing BIOS settings
So, to begin with, we will consider the most unpleasant situation when, for some reason, changes to the parameters were made in the BIOS, the settings were reset, or the system simply “crashed”.
In this case, when deciding how to enable all the kernels on Windows 7, you need to build 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 versions, the section names may differ or can be found 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 involved 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 means of the OS itself.
How to enable all kernels on Windows 7 in this situation? Here it is necessary to call the Run menu and write the "msconfig" command there to enter the configuration parameters. Here we have the “Download” tab we need. Just below the main window is a button for additional parameters. By clicking on it, we get to the settings menu.
On the left we use the line of the number of processors 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 enable 4 cores on Windows 7. As already clear, we select this quantity from the list. After the changes, save the configuration and restart the computer.
But there are pitfalls. With such operations you need to be very careful. It is important to know that when activated, each core must have at least 1 GB (1024 MB) of RAM. If the indicator of the “RAM” bars does not correspond to the necessary values, there is nothing to try. So you can get only the opposite effect. In this case, we are talking about stationary computers of manual assembly. 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, after all, for 2-core processors, as a rule, at least 2 GB of “RAM” corresponds to it, for 4-core processors - at least 4 GB, etc.
The debugging and blocking points of PCI must be disabled without fail.
Instead of an afterword
So we figured out how to turn on all the cores of the Windows 7 processor. In general, as already understood, this process in Windows 7 and above does not cause any special difficulties. Another thing is that you need to analyze the system configuration in advance for the correspondence of the number of cores and RAM slots, because as a result a complete slowdown of the computer or, in general, its failure may appear. So it is better not to joke with such settings if there is no firm belief that the inclusion of absolutely all the cores is an absolute necessity.
However, there should be no problems with the BIOS either. Most systems, when resetting to default parameters, imply the maximum use of the capabilities of modern multi-core processors. Such a decision was made, so to speak, in extreme cases.
