Tell If an Intel Processor Is Locked?
Intel processors use a "Base Clock" and "Multiplier" to determine the set speed of a processor. These two values multiplied together give the speed, in Hertz, of any given Intel processor. Some models of Intel processors allow for this Multiplier value to be changed by the user to achieve what is known as an "Overclock" which increases the processor's computing speed. If an Intel processor is set so that it is unable for the multiplier to be changed it is referred to as a locked processor.
Instructions
1. Restart the computer.
2. Press the appropriate key to enter the computer's BIOS. The appropriate key to press will be displayed and easily identified after restarting the computer on the screen. This key is usually either the delete key or the F1 key.
3. Use the right arrow key to move through the BIOS menus until you are on the menu named "CPU."
4. Use the down arrow key to move through each heading within the CPU menu until you find a heading labeled "Multiplier."
5. Review the value to the right of this heading. If it is grayed out and unchangeable then your Intel processor is locked. If you are, however, able to change this value your multiplier is not locked and you may overclock the system.
