How to Get More GHZ on Your Processor

By David Tate

Computers have become a way of life for most people these days. It would be hard to imagine a world without them now. As is the trend with all technologies, we are always trying to find ways to make computers more powerful while making them smaller and cheaper. One of the best ways to cheaply improve performance on your computer is to overclock your CPU. This can be a simple process if done correctly.

Things You'll Need

  • Computer
  • Keyboard
  • Mouse

Overclocking your Intel CPU

Step 1

Enter the BIOS. Do this by holding down a key while your computer is booting up. It is usually either the "Delete," "F1" or "F2" key.

Step 2

Navigate to the screen that will allow you to modify the "Front-Side Bus" Speed (this will be called "Base Clock" on a Core i7 CPU). For the most part, the front-side bus will show up as "FSB" on your BIOS screen.

Step 3

Choose the option that will unlink your front-side bus clock speed from your RAM. In the referenced Web page below, it is called "FSB Memory Clock Mode."

Step 4

Increase your FSB by 20 MHz (read 20 megahertz). Save the change and reboot your computer. If your overclock is successful, you can continue to increase the speed. If your computer does not boot, see the section of the referenced article titled "Step 7: Beep! Beep!"

Step 5

Navigate to the screen that will allow you to modify the CPU's voltage.

Step 6

Increase the voltage of your CPU. To find out how much to increase the voltage, search Internet forums to see what other people have done. Every motherboard and CPU is a little different, so there's no set amount.

Step 7

Test your computer to make sure it runs smoothly. A good overclock can easily take a CPU running at 2.66 GHz stock speed and have it running at 3.44 GHz.

Overclocking your AMD CPU

Step 1

Enter the BIOS. Do this by holding down a key while your computer is booting up. It is usually either the "Delete," "F1" or "F2" key.

Step 2

Navigate to the screen that will allow you to modify your CPU's multiplier setting.

Step 3

Increase the multiplier by a factor of 1.(Example: if it's set at 13x, change it to 14x) Reboot your system. If it's successful, continue increasing the multiplier. If your computer does not boot, see the section referenced below labeled "Section 8: It Won't Boot." It should be noted that some AMD CPUs are locked, and don't have the ability to increase the multiplier.

Step 4

Navigate to the screen that will allow you to modify the HyperTransport (HT). HyperTransport is an interface between the chipset of the motherboard and the CPU. In the article referenced below, the motherboard BIOS labels it as "CPU <-> MB HT Speed."

Step 5

Lower the HT speed by a factor of 1 or 2. Most motherboards will have a default of a 5x multiplier. It should be moved down to a 4x or a 3x.

Step 6

Navigate to the screen that will allow you modify the CPU frequency. You should see the CPU frequency set at somewhere around 200 MHz (read 200 megahertz).

Step 7

Increase the CPU frequency by 10 MHz. Reboot your computer. If the overclock is successful, continue increasing the frequency. If your computer does not boot, see the section referenced below labeled "Section 8: It Won't Boot."

Step 8

Navigate to the screen that will allow you to modify the CPU's voltage.

Step 9

Increase the voltage of your CPU. To find out how much to increase the voltage, search Internet forums to see what other people have done. Every motherboard and CPU is a little different, so there's no set amount.

Step 10

Test your computer to make sure it runs smoothly. A good overclock can easily take a CPU running at 3.2 GHz stock speed and have it running at 3.43 GHz.

Tips & Warnings

  • Overclocking can be very dangerous if done incorrectly. It can lead to corrupt data and even destroyed hardware. Changing the voltage on the CPU should be done with special caution since too much voltage can easily fry a chip. One of the biggest threats from overclocking is heat. Make sure you have adequate cooling for your system. Also make sure you have a large enough power supply to support the tweaks you're making. Not enough power can easily bring about a bad overlocking situation.
