How to Increase Vcore


Vcore refers to the voltage supplied to the CPU. This value varies, depending on what CPU you have in your system. For instance, the VCore for an AMD Phenom ll CPU is 1.375 volts when the CPU is under load. Modern CPUs have the ability to "throttle down" when they are not working. The speed and voltage are automatically lowered. Increasing the Vcore is usually done when overclocking a CPU. Overclocking refers to making a CPU run faster than its stock speed. Overclocking a CPU and increasing the Vcore will result in increased heat and can damage the processor.

  • Turn on the computer and look for the prompt to enter the BIOS. You will be prompted to press a key, usually the "Delete" key. Different systems use different keys. When you see the prompt, press the appropriate key.

  • Use the arrow keys to navigate to "Advanced Settings." "Jumperless Settings" will be highlighted. Press "Enter."

  • Look for a setting labeled "VCore" or "CPU Overvoltage." Use the arrow keys to navigate to this setting. Press "Enter."

  • Increase your voltage by pressing the plus "+" key. Some systems will show the increase in voltage that is added to the stock voltage. For instance, your stock Vcore is 1.375 volts. This system will only show the increase: +.0015 volts, +.0030 volts, and so on. Some systems will show the total voltage increase: 1.3765, 1.3785, and so on. Be sure to determine which system you have.

  • Set your desired voltage. Press "Esc." Use the arrow keys to navigate to "Exit." Press "Enter." "Exit and Save Changes" will be highlighted. Press "Enter."

Tips & Warnings

  • Search the Internet to find the stock and maximum recommended voltage for your specific CPU. Raise the Vcore in small increments. It is a good idea to use an aftermarket heat sink to dissipate the added heat. Factory heat sinks do not hold up well with increased heat.
