How to enable all processor cores

Many inexperienced users of a PC or laptop are wondering how to turn on all the cores of a device when applications that are difficult to implement fail.

How to enable the second processor core: instructions

As a rule, the second core of the processor is disabled to save electricity. To enable it, you need to refer to the commands in the Start menu.

  1. On the Start menu, click Run. In the window that appears, enter the command "msconfig". In addition, you can use the "Win" and "R" keys to open the "Run" window.
  2. In the window that appears, go to the "Download" tab. A list opens where you need to select the operating system you are using (in case there are several installed on your computer). Now click on the "Advanced Options" button.
  3. You will see the item "Number of processors". Put a tick near it, and from the drop-down menu, select the number "2". In addition, pay attention to the item "Debugging" and "PCI Balancing". It is necessary to make sure that there are no check marks on these functions.
  4. Now click "OK" and then "Apply."
  5. Close all windows and running programs. Save all unsaved documents. Enter the Start menu and restart the computer.
  6. After reboot, open the task manager, which can be called using the keyboard shortcut "Ctrl + Alt + Del". In the manager, open the "Performance" tab.
  7. In case if 2 core is connected, you will be able to observe two independent schedules "CPU load history".
  8. For a more subtle control of the processor, you can assign different cores for the work of various programs. To do this, refer to the "Processes" tab and, by right-clicking on the desired program, select the "Set matching" item.
  9. After that, you will have the opportunity to choose the work of one or another kernel (or all together) to serve a specific application.

In a similar way, you can turn on all the processor cores.

Sometimes, to set up a stable computer, it is necessary to change its components, including the processor. To replace it, you need to be able to turn off the processor.
