If your computer is running too slow and you don’t have money to upgrade, you can always learn how to overclock the CPU. While overclocking will speed up your computer, overdoing it might damage your computer and void the warranty. Overclocking will also heat up the components, so make sure it has a cooling system.
Check your motherboard manual and find out what key to press to get into the BIOS. Usually it’s the Del key.
Reboot your computer and press the Del key to get into your BIOS.
Look for the Advanced Settings on the BIOS and look for “CPU Clock Ratio”. Increase the value in increments like .5 or .1.
Look for the “CPU frequency” and change the number to a higher value. Again, increase the amount incrementally and not too high. If you set the values too high your computer will not be able to start up.
When you are done, look for “Save to CMOS and EXIT (Y/N)”. Choose Y then press Enter.
Exit the BIOS setup and reboot your computer.
More about Overclocking
If you are going to overclock your computer, bear in mind that there are some risks and if you increase the settings frequently the processor will not be able to overclock anymore. Just to be sure, limit your CPU voltage speed boost by no more than 10%. You also need to be certain that there is sufficient cooling for your computer.
The lack of cooling fans and airflow will cause your computer to overheat. Because of this fact, it is advisable to put a powerful cooling fan at the bottom and top of your computer case. Adding a cooling system will increase the speed along with the built in cooling fan.
Do not attempt to overclock unless you know exactly what you’re doing, and research first so you will avoid making mistakes. Laptops cannot be overclocked and OEM PCs make it difficult to overclock. As a rule, custom built computers are easier to tinker with.
Options for Overclocking
The BIOS remains the best option for overclocking. It is by far the easiest option, but others let you overclock by adjusting one of the motherboard jumpers. There are also some applications that allow you to overclock the computer inside the OS, but most experts recommend that you make the changes in the BIOS.
Adjust the CMOS
If your overclocking attempts refuse to work or become unstable, restore the settings. If this occurs, you can go back to the BIOS settings and restore the settings to the default. In other computers you need to clear the CMOS settings. The CMOS is a type of memory on your motherboard where BIOS information is stored. You can change the CMOS settings by adjusting the CMOS jumper position on your motherboard, wait a couple of minutes and then restore it to the original position.
Also keep in mind that if your processor is multiplier locked, then overclocking will only be possible via the Front Side Bus. If this is the case, make sure that the increases are also in small increments. Now that you know how to overclock the CPU, remember not to get too carried away, and make sure that you don’t make too many drastic changes so you can restore the settings if needed.
