Overclock An Aluminum Imac

Overclocking an iMac lets it run at maximum capacity.

Overclocking a computer pushes the motherboard to maximum power, making the computer go as fast as it can. This can help you get the best performance out of your computer, but it should not be done permanently, because it can lead to the machine overheating. On PCs, you can overclock via "System Settings, but on iMacs, you need to modify the hardware itself. If you have an aluminum iMac, one screw on the bottom lets you access the equipment that you need to modify.


1. Turn off the iMac, and unplug it.

2. Turn the computer upside down.

3. Unscrew the screw on the bottom. Unlike earlier iMacs, the aluminum model only has one visible screw.

4. Remove the lid under the screw. You will see the RAM cards along with another set of six screws to access the rest of the machine.

5. Unscrew all six screws, and remove the second lid. Be carefully removing it, because you will need to maneuver it around the RAM cards, which will stay in place. You will now see the computer motherboard.

6. Find the sliders marked R35-R42. These are the electrical resistors and will be located near the back of the machine.

7. Write down whether each slider is in the left or right position. You will need this information to restore your computer when you are done overclocking it.

8. Move all of the sliders to the right-hand position. You may be able to do this with a fingernail. Otherwise, try a toothpick or pen.

9. Close up the computer.
