What Is Overclocking and What You Need to Know About It Featured Image

Overclocking is a very popular term used in the world of PC building, but what exactly is it? If it is a quick and free way to speed up your PC, why isn’t every user doing it?

The Basics of Overclocking

In simple terms overclocking is the act of pushing your computer’s components faster than it was originally intended by the manufacturer. Though most commonly the CPU and GPU are overclocked, other components can be overclocked as well. Quite literally, you are speeding up the clock speed. The clock speed is measured in hertz. This is why there is a speed difference between an Intel i5 1.4Ghz and an Intel i5 2.7Ghz processor, for instance. Even though they are both dubbed an “Intel i5,” they have differing clock speeds. One can essentially acquire a lower-end, cheaper processor and then overclock it to achieve faster speeds. But is this really a worthwhile modification for the average consumer?

Pros of Overclocking

Ultimately, overclocking will make your processor substantially faster and is the main reason for overclocking. After all, doesn’t everyone want their PC to have a little extra hop in its step? In other words, if you are struggling to complete even basic tasks on your PC, it may be worthwhile to overclock your processor for a little added boost. Do remember, though, that overclocking is not necessary for basic operations such as writing and lightweight applications. However, for tasks such as rendering and editing video, you will definitely see a difference.

One can overclock a GPU easier than a CPU. A piece of downloaded software is used rather than the computer’s bios when overclocking the GPU. This way a user can directly see and manipulate the operations with the mouse rather than keystrokes on the keyboard in the BIOS.

Cons of Overclocking

Overclocking can overheat and even fry a PC if it is set up incorrectly. In most cases manufacturers set the clock speed based on what is safe for the cooling system in use. By overclocking your machine, it is essentially mandatory to find a new cooling system. Many will opt for a water-cooling system as the network of tubes and fans is generally better at dispersing heat than a fan-based system with a heat sink. Getting a new cooling system can sometimes cost more than buying a speedier processor to begin with, in which case overclocking is not practical monetarily.

The BIOS can be a complicated place if you do not often make modifications to your PC. One wrong move can severely damage your PC and render it unusable. If you are unsure of the reason behind inadequate performance, consider upgrading RAM or cleaning your PC. Overclocking should not be the first consideration for a faster PC.

Final Thoughts

When starting a PC build, it is best to approach the project with the mentality of buying the appropriate processor for the task. Unfortunately, some will buy an under-capable processor with the knowledge of how to overclock it. However, if you are just trying to get a little bit of extra power out of your PC, overclocking the processor may be the right route for you. Just know the ins and outs of the BIOS, have patience, and be willing to learn how to go about the process on your specific PC.

In 1969, László Bélády and two IBM colleagues published a paging-machine anomaly showing FIFO could make four memory frames suffer ten page faults after three frames suffered nine, leaving generations of operating-systems students staring at the moment more memory became the wrong answer
When Bell Labs engineer Karl Jansky pointed a rotating antenna at the sky in 1932 looking for sources of transatlantic radio static, he kept picking up a faint hiss that peaked every 23 hours and 56 minutes, and he eventually realized he had become the first human to hear the center of the Milky Way.
The colour magenta does not exist anywhere in the spectrum of visible light, and your brain manufactures it on the spot whenever red and blue cones fire together, inventing a hue to fill a gap that physics never bothered to provide.
On 28 May 2009, Google demoed a product called Wave on stage at I/O for 80 minutes and got a standing ovation from developers who had no idea what they had just watched, and 15 months later the company quietly shut it down because almost nobody could explain to a friend what it was actually for
When Clair Patterson set out in 1948 to measure the age of the Earth using lead in meteorites, his samples kept coming back contaminated, and the seven-year detour he took to find the source ended with him almost single-handedly forcing leaded gasoline out of American cars by 1986.
The IBM 305 RAMAC stayed in production until 1961, weighed more than a ton, stored five million characters on fifty spinning platters, and still drew customers because the alternative was a room full of punched cards
In 1977, Ann Druyan recorded an hour of her brainwaves and heartbeat two days after she and Carl Sagan agreed to marry, and NASA pressed the compressed minute onto Voyager’s Golden Record as a private love signal now more than 25 billion kilometres from Earth
