Advice 1: How to enable cores in the bios

The process of inclusion of additional core in the BIOS is to select the checkbox in the Enabled field of the corresponding section. The main problem are determining the possibility of performing the unlock operation of the CPU and find the right partition.
How to enable cores in the bios
Instruction
1
Make sure that the motherboard of the computer meets all the requirements for enabling additional cores, and remember that the chosen procedure may lead to malfunction of the system.
2
Don't forget to reboot the computer system after the operation of unlocking additional cores and test it for functionality.
3
For Asus: - Southbridge AMD SB750 and 710 click on the Advanced tab and select CPU Configuration, select the option Enabled in the line Advanced Clock Calibration and repeat the same action in the box that appears Unleashing Mode;- nVidia nVidia - go to the Advanced tab and use the Configurarion JumperFree section, mark the checkbox in box NVIDIA Core Callibration to perform the desired action;- a motherboard that supports the Asus Core Unlocker - go to the Advanced tab and use the Activation CPU Core with Asus Core Unlocker.
4
For MSI:- Southbridge AMD SB750 and 710 open the Cell Menu and apply the flags on the field Advanced Clock Calibration, repeat the same action in the line Unlock CPU Core;- chipset nVidia - expand Cell Menu and navigate to the NVIDIA Core Calibration;- a motherboard that supports MSI's Unlock CPU Core - unlock Cell Menu and select Unlock CPU Core.
5
For AsRock:- Southbridge AMD SB750 and 710 click on the Advanced tab and specify the command Advanced Clock Calibration (possible options: open, menu OS Tweaker and select the same command), the L3 cache is managed in the section L3 Cache Allocation;- chipset nVidia enabled NCC - go to the Advanced tab and select NVIDIA Core Callibration, make the inclusion of additional poison in the row Active Core Setup; the motherboard that supports UCC open menu OS Tweaker and go to ASRock UCC, include additional in - line CPU Active Core Control.

Advice 2 : How to disable -

Disabling processor cores usually require you to run any outdated programs. You don't have to torture your computer configuration in the BIOS, sometimes just enough to run the program in compatibility mode.
How to disable -
You will need
  • program emulator.
Instruction
1
Disable the second core of the CPU using a setup item HyperThreading. To do this, restart the computer, when it loads press Delete and if required, enter the password on the BIOS.
2
Using the arrow keys to navigate through the program menu of the BIOS, look for settings, HyperThreading, this feature in some models of motherboards is responsible for activating a second processor core. Uncheck use.
3
Apply the changes on exit of BIOS. Similarly, a return operation of the second core when needed, just by enabling HyperThreading. Remember that this method is valid not for all models of motherboards and processors.
4
If you need to change the number of cores to run a particular program (often this applies to games and applications to the year 2000), use the application compatibility with the operating system. To do this, click the right mouse button on the icon of the desired program, click "Find object", click in the folder again, right-click the startup file and open the context menu.
5
Select one of the tabs of the properties of the function run in compatibility mode with earlier versions of the Windows operating system. Try to specify among them one that the release date is most consistent with your program. Apply the changes.
6
If you use compatibility mode, try installing on your computer special programs-emulator earlier versions of the operating system, the kind you might find in free access in the Internet. Open the program only after starting the emulator, because otherwise there will be no result from its use.
Note
Be careful when working in the BIOS, because it is responsible for the work of all equipment.

Advice 3 : How to enable second core XP

The second processor core is usually enabled by default in Windows XP, but some programs require it to disable to operate correctly. After that, it may be difficult to return to the original settings.
How to enable second core XP
You will need
  • - optimization program.
Instruction
1
Make sure that the second core of the processor is disabled. To do this, open Windows task Manager by pressing Alt+Ctrl+Delete or Ctrl+Shift+Esc then navigate to system performance. Notice how many parts is divided the download box CPU, if two, both cores are turned on and functioning at the proper level.
2
In the case where there is only one - two in the operating system Windows XP, download and install an optimization program that configures the operation of the processor. After installation go to manage your computer's hardware and activate both cores of the processor. Mandatory, restart the computer, even if not required by the optimization program, do not forget to save the changes.
3
To test the operation of both cores on the machine turn it on and run any game or program's system requirements which suggest that you have a dual core processor. Run task Manager and in the view tab of system performance, review the workload of both elements. It may be different for them because the load is not always distributed equally.
4
Turn on the second core of the CPU using driver rollback motherboard installed in your computer. To prepare a driver for installation, best updated version. Reinstall the software, then again restart the computer.
5
Check the operation of both cores in device Manager. This sequence works in very rare cases. You can also try a system restore from an earlier condition, but in this case, will be cancelled and the rest of the changes over a period of time.
Useful advice
Less likely to make changes to the operation of the processor.

Advice 4 : How to enable second core

In personal computers or laptops with dual core processors running Windows XP, most default involved two cores, however some of the programs to work correctly, require that you disable one of them.
How to enable second core
Instruction
1
Make sure that the second core of your CPU disabled. To do this, open the task Manager with the help of simultaneous pressing of keys Ctrl+Alt+Delete or Ctrl+Shift+Esc.
2
Then click the Performance tab. Let's see how many Windows are divided from the part of the "CPU" (CPU usage). If you have two Windows CPU usage is at appropriate levels, there are both core. If the window is one, respectively, included only one core of the processor. In the second case, you must perform the following steps to enable second core.
3
Download optimizing Windows XP and install it on your computer. It will allow you to properly configure the CPU. Go after the program is installed under"manage hardware" on your computer and activate the second processor core.
4
Restart your PC or laptop, in this case restart is required, even if this will not require optimization program. After you change the settings don't forget to save the changes by clicking on the appropriate button - "OK".
5
Check the operation of the processor and its cores. To do this, turn on the computer. Run any program or game, the system requirements which include a dual-core processor.
6
Run the task Manager (Ctrl+ Alt+Delete or Ctrl+Shift+Esc), go to the Performance tab. View the workload of both elements of the processor. If you have two Windows, so all actions are done correctly and the second - system included. In this case, remember that the load on each of the cores may be different, as it is not always distributed equally.
7
To enable the second core processor and a slightly different way. Install the driver rollback for your motherboard. Reinstall the software, to do this it is best to use updated versions of the programs. Restart the computer, check the both cores in device Manager as described above.
