What is CPU overclocking?

You guys must hear about CPU overclocking. But still, don’t know what is it and how it’s work. But don’t worry after reading this article you will get to understand everything. CPU overclocking is basically increase the clock speed or frequency of any particular processor.

By overclocking you can increase the overall performance of that processor and get some extra output. But Overclocking a CPU is not a permanent solution if you want faster processing.

If you overclock your CPU regular. Or like Whenever you turn on your computer and did overclock. It may cause serious damage or decrease the CPU’s overall age.

How overclocking works?

Every processor has a clock circuit. It places inside the chip. The circuit simply does that, it changes their values rapidly. The values are simple binary output “0” and “1”. This is basically called CPU’s clock.

The modern processor’s clock working and changes its binary output values very fast. For example, 500hz means 500 cycles per second. If 500KHz means 500 x 1000 = 5,00,000 cycles per second. Similarly, 500MHz means 500 x 10,00,000 = 50,00,00,000 cycles per second.

Now, every time the circuit goes “on” or “off”, it’s complete one cycle. In that one cycle how much tasks can complete the processor, its depend on the CPU’s strength.

Overclocking basically does, it increases the rate of speed of changing values. The more speed the faster will be in games and application.

Do you need CPU overclocking?

Well, It’s to gain extra performance in any application. There could be multiple reasons for overclocking. This could be the time it takes to open Photoshop or maybe it’s in games and then it’s frames per second.

The main thing to remember is that there are lots of different components in your computer and they’re all strained in a different situation. So overclocking your processor might help in workloads or in games.

Things to take care before overclocking.

For overclocking you need such a motherboard which allows overclocking. And of course, a unlock CPU. Intel and AMD both are capable of overclocking. But only Intel’s K series and AMD’s all Ryzen desktop processor can be overclocked.

Overclocking a CPU is pretty straightforward, it’s simple, it’s mainstream. But it does carry some element of risk and ultimately will probably void your warranty of your CPU. If something goes wrong you could damage some of your hardware.

Overclocking require more power. As we add more power we’re also generating more heat, which can ultimately destroy your CPU. If the temperature hit 100 degrees your computer’s in trouble. So make sure you have a proper cooling system in your PC. Liquid cooling would be much better.

How to overclock your CPU

You can overclock your CPU through motherboard BIOS settings. But if you are complete beginner use windows-based tools. For Intel CPU you can download “Intel® Extreme Tuning Utility (Intel® XTU)” and “AMD Ryzen Master Utility” for AMD’s CPU.

If you want to overclock through BIOS you can do that. keep in mind every motherboard’s BIOS is bit different. So you may have explored to find the settings. But the main concept can be applied to both options.

Step:1 Stress Test and base temperatures

After you open the Softwares you should do the stress test on default settings of Your CPU. It may take some time. After successfully stress test look at your core temperature. If the temperature goes above 80 degrees I highly recommend improving your cooling before further procced.

If your temperature is well under it you can go further and can push your chip for higher frequency.

Step:2 Get into BIOS

After about 5 to 10 minutes, when temperature stable restarts your system. During restarting press the function keys to get into bios. You can google search to know the function keys for your motherboard.

The Interface and UEFI could be different for the different motherboards. But the base settings will be the same. So you don’t need to worry about that.

Step:4 Go for auto-overclock

Before overclocking manually go for auto-overclocking. This is the easiest way to overclock your CPU. The majority of work done by the motherboard.

Most motherboards include overclocking section/profile. By auto-overclocking, you can hit that particular frequency which is mention on your BIOS ( It usually ragging from 3.5GHz to 4.0Ghz ). BTW the frequency depends on which processor do you use.

But if you did not satisfied with auto-overclock and push your CPU frequency higher you can do overclocking manually.

Step: 5 Multiplier

Your CPU clock speed determined by the simple multiplication of CPU’s “BCKL” ( or base clock ) frequency with the multiplier also called as CPU ratio ( for example, multiplier 35 ). In your case multiplier could be different like 36 or 40 depending on your CPU base frequency. Don’t worry multiplier will clearly be mentioned in UEFI or BIOS settings.

Let’s assume processor’s “BCLK” frequency is 100MHz ( it usually 100MHz ) and the multiplier is 35. So 35*100MHz=3.5GHz ( the base frequency of your CPU )

Let’s overclock the CPU from 3.5GHz to 4.0GHz. So you only need to change the multiplier from 35 to 40. Now save the settings and exit.

Boot your computer, open the Intel’s XTU or AMD’s Ryzen Master utility and run the stress test and look at the core temperature. If the stress test is successfully done and the temperature is OK, run some benchmarks software “cinebench 4D” or “Geekbench”.

Step: 5 Test, repeat, Find the limit

If your computer is stable enough, boot into BIOS and changes the multiplier again. Run stress test each time after changing the multiplier. Repeat this process until your computer goes unstable.

If you see a blue screen of death or CPU throttle down itself during booting. Means your computer is unstable. To fix that you need to change Vcore voltage.

Step: 6 Changing the voltage

To resolve the blue screen problem you need to work with Vcore voltage.

Boot into your BIOS and find Vcore voltage mode. Before changing in voltages better do some research what is the stoke Vcore of your CPU.

We suggest starting increasing the voltage of 0.01 each time. After increasing the voltage, try to boot to the computer.

Repeat the process until your computer is boot successfully and stable at your target frequency.

Once you’re comfortable with overclocking increase the voltage like 0.05. It’s all about how your CPU response when you increasing the voltage.

Step: 7 Run the benchmark

After successfully done everything and reach the peak point of your CPU. Run some benchmark and play some games to measure how much extra performance get after overclocking.
