Check the motherboard in your computer for CPU requirements.
Your computer (or more specifically your motherboard) can only handle a certain amount of power. Just as your computer's CPU can only deal with a certain amount of random access memory, your motherboard can only deal with a certain amount of processing power. To find out what that limit is and identify the fastest speed CPU that your motherboard can support, you first need to find out exactly what kind of motherboard is in your machine.
Instructions
1. Turn off your computer.
2. Use a screwdriver to open your computer's case. The long, flat circuit board toward the base of your computer's case is the motherboard. Look for the model number that is printed on the motherboard. Write this number down. Then close up your computer case and turn it back on.
3. Open your web browser and go to Motherboards.org (see References).
4. Click on the "Search" tab at the top of the Motherboards.org site and type the model number you found on your motherboard into the search form that opens. This will bring up a full listing of all of the technical specifications associated with your motherboard. Right at the top of this listing will be the fastest speed and type of CPU that you can use with your computer.
