what is overclocking and how to do it?
Answers
Your computer’s CPU comes from the factory set to run at a certain maximum speed. If you run your CPU at that speed with proper cooling, it should perform fine without giving you any problems.
However, you’re often not limited to that CPU speed. You can increase the CPU’s speed by setting a higher clock rate or multiplier in the computer’s BIOS, forcing it to perform more operations per second.
This can speed up your CPU — and therefore speed up your computer if your computer is limited by its CPU — but the CPU will produce additional heat. It may become physically damaged if you don’t provide additional cooling, or it may be unstable and cause your computer to blue-screen or restart.
Can You Overclock?
You may not even be able to overclock your CPU. Many motherboards and Intel CPUs ship with locked multipliers, preventing you from tinkering with their values and overclocking your CPU. Intel sells more CPUs with unlocked multipliers, targeted at enthusiasts that want to overclock and squeeze every bit of performance out of the CPU. (Look for CPUs with “K” in their model number.)
How to Overclock Your CPU
- Every CPU is different, and every motherboard has different BIOS options. It’s not possible to provide a guide for overclocking that will work for everyone. But we’ll try to outline the basics, anyway:
- Ensure Your System Has Proper Cooling: Your CPU comes with a heat sink and fan from the factory, which are designed to handle the amount of heat produced at the CPU’s standard speed. Speed it up and it will produce more heat. This means that you’ll probably need additional cooling. This can be in the form of an aftermarket heat sink that can dissipate more heat and/or a more powerful CPU fan that can blow the hot air away. You’ll want to have a good amount of free space inside your computer’s case so the air can move around and eventually be blown out by the fan in your computer’s case, which may also need to be upgraded. Air flow is very important for handling heat, as just having a heat sink or CPU fan won’t help if all that hot air stays trapped inside your case.
- Consider Water Cooling: Hardcore overclockers may want to use a water-cooling system, which is more expensive. Water-based coolant is pumped through tubes inside of the case, where it absorbs the heat. It’s then pumped out, where the radiator expels the heat into the air outside of the case. Water-cooling is much more efficient than air-cooling.
- Overclock in the BIOS: You’ll need to go into your computer’s BIOS and increase the CPU clock rate and/or voltage. Increase it by a small amount, then boot your computer. See if the system is stable — run a demanding benchmark like Prime95 to simulate heavy use and monitor your computer’s temperature to make sure the cooling is good enough. If it’s stable, try increasing it a little bit more and then run another test to ensure the PC is stable. Increase the amount you’re overclocking by bit by bit until it becomes unstable or the heat is too much, then drop back down to a stable level. Overclock little by little to ensure it’s stable, don’t just increase your CPU’s speed by a large amount at once.
