How To Enable Cores In Windows 10

To run certain applications that are not compatible with multi-core operations or to salve power it may be necessary to disable a core in a multi-core CPU. This article will show you how for both Windows and Linux operating systems.

How to disable a core?

In Windows systems, it is possible to disable a core through the system configuration window. Cull the number of processors that should be enabled or disabled and restart the computer for the settings to take effect.Disabling a core in Linux tin can be washed through the chow carte and add parameters to the kernel entry. These parameters are sent directly to the core when the Linux is starting. The Linux organization has to exist restarted later on the modifications to disable a cadre in a multi-core CPU are fabricated.

Why disable a core?

It can sometimes be quite useful with a multi-core processor to be able to determine whether a core is working properly during rise in frequencies or for testing purposes. This tin can be done by disabling a core, thereby isolating the potentially problematic ane. Sometimes this procedure is necessary to run certain applications, which are not compatible with multi cadre processing.

Note that this process will non bear on physically your hardware, but your Bone (Windows or Linux) volition but ignore the core(south) you selected.

What is the procedure when using Windows?

• Open the first carte, click on Run, type in msconfig and click on OK
• In the System Configuration window click on the Atart sub menu and the on Advanced Options button

• In the second window that appears, you should be provided with an option for enabling and disabling the processors as you wish
• Validate your entry by clicking on OK
• Restart your PC

What is the procedure when using Linux?

When using Linux the procedure is quite different. When starting up your PC, you should discover the Chow menu, which is responsible for launching Linux. Select the entry you want to use, press the E key and a menu will appear (depending on the version used).

          title         Ubuntu seven.ten, kernel 2.6.22-14-generic          root         (hd0,v)          kernel       /boot/vmlinuz-2.vi.22-14-generic root=UUID=a8a39729-9d2a-425b-b84b-ecc5c7dad104 ro quiet splash          initrd                                /boot/initrd.img-two.6.22-14-generic          quiet        

Using the arrow keys, go the line starting time with the give-and-take "kernel" and press E once again.

Be enlightened that you are editing the line, which defines the path to your Linux kernel (core). At the stop of the line, add the post-obit command:

maxcpus=i

The end outcome should be:

kernel  /boot/vmlinuz-two.half dozen.22-14-generic root=UUID=a8a39729-9d2a-425b-b84b-ecc5c7dad104 ro quiet maxcpus=1

Note: que ro, quiet and maxcpus are the parameters sent to the core when starting up Linux.

Press the B key to start Linux.
