How To Overclock Your CPU: Push The Limits

How To Overclock Your CPU: Push The Limits.

Overclocking your CPU will increase its working velocity and boosts its efficiency.

If you’ll be able to arrange a secure overclock, you’ll have a smoother pc expertise and will even get FPS enhance in CPU-intensive video games.

However, you want to proceed with warning and work slowly when rising the CPU frequency, voltage, or clock velocity to keep away from inflicting harm.

I might be using the next parts and present how I overclock it to offer you a sensible instance.

CPU: AMD Ryzen 7 1700 Eight-Core Processor
Motherboard: ASRock x370 Taichi
AIO Cooler: Gamer Storm Captain 240EX White

For laptop-specific directions, view our How To Overclock Laptop CPU information.

Check Support for Overclocking

The CPU frequency or velocity is a multiplication of the CPU core ratio or multiplier and the bottom clock velocity (BCLK):

CPU Frequency = BCLK * Multiplier

While overclocking a CPU, we are literally rising this core ratio. This is simply potential for CPUs that include unlocked cores.

  • Such CPUs embody all out there AMD CPUs and Ok, KF and X-series Intel processors. But there could also be exceptions, so examine your CPU’s official assist web page first.
  • You also needs to notice its Base Clock and Max Boost Clock on the identical time.

Keep in thoughts that Max Boost could not symbolize the utmost frequency you’ll be able to obtain. Depending in your CPU cooler, the standard of thermal paste, motherboard design and BIOS model, the frequency could go a lot larger.

For Intel motherboards with out unlocked cores, just some auto-OC choices or BCLK (Base Clock) overclocking can be found. Overclocking the bottom clock additionally will increase the RAM frequency on the identical time.

Note: Based on AMD and Intel guarantee phrases, overclocking the CPU past the inventory specs could void its guarantee. So ensure you are snug with it earlier than continuing any additional.

Establish a Baseline

Before overclocking your CPU, it’s best to run stress and benchmark checks to ascertain a baseline. Note down the CPU temperature, frequency, voltage and benchmark scores for future comparability.

Also, be certain that to decide on this system meant to your CPU like 3DMark, Cinebench, Prime95. You need to put strain on the CPU reasonably than one other element.

Get to BIOS

To overclock your CPU in BIOS, first get to the BIOS/UEFI Interface. After turning in your pc, press the BIOS key as quickly as you see the producer’s emblem display screen.

Alternatively, you can begin urgent the keys repeatedly even earlier than that to get the timing proper.


The BIOS key for my ASRock motherboard was Del or F2. The key you want for another common motherboard are as follows:

If the BIOS key doesn’t work, you might have enabled Fast Boot or related settings. In such instances, entry UEFI Firmware Settings by means of the Advanced Startup choices.

Use Automatic Overclock

If you might be simply stepping into overclocking the CPU, I like to recommend beginning with computerized overclocking choices. They truly present a major enchancment in CPU frequency and efficiency.

  • You could discover completely different choices reminiscent of Intel Turbo Boost Technology, AMD Precision Boost Overdrive, Base Frequency Boost, relying in your motherboard.
  • Look inside Advanced CPU Configuration or simialr choices within the Overclocking (OC) tabs to search out them.
  • Some motherboards like ASUS additionally include computerized tuning options that allow completely different ranges of overclocking relying in your want. For ASUS, these are EZ System Tuning and EZ Tuning Wizard.

After enabling such choices, save the adjustments and restart your PC. Then run stress and benchmarks checks to investigate the soundness and efficiency enchancment.

Manually Overclock CPU

Auto-OC choices are usually not essentially the most optimum settings. If you need to get one of the best overclocking outcomes, manually change the overclock settings as an alternative.

However, understand that you can’t depend on others to get the required OC values. Even for identical fashions, separate CPUs have completely different tolerances on account of manufacturing variations.

You should experiment with the values and slowly work your approach as much as get the optimum configuration.


The aim is to have the best potential CPU frequency with the bottom supporting CPU Voltage. The voltage can also’t be so excessive that it overheats the CPU. 

In common, it includes the next steps:

Increase CPU Frequency

  1. First, allow Manual Overclock mode. As you’ll be able to see above, I’ve set CPU Frequency and Voltage Change inside OC Tweaker > CPU Configuration to Manual.
  2. Slightly enhance the CPU Multiplier. Only modify the multiplier by 1 at a time.
  3. If you straight see the CPU Frequency, enhance it by 100 MHz.
  4. Save and exit the BIOS, then restart your pc.

Test for Stability and Adjust CPU Voltage

  1. If the pc doesn’t restart accurately, there isn’t sufficient energy on the chip to carry out at that stage.
  2. Increase the CPU voltage on the BIOS to see whether or not an elevated energy circulate fixes the issue. Only use increments of 0.05 V and don’t let the CPU voltage cross the secure restrict (normally 1.4-1.5V).
  3. Save your settings and get inside your OS.
  4. If the PC begins correctly, stress take a look at the CPU to see the way it performs below heavy load.
  5. When the system runs stably, enhance the CPU Multiplier once more and proceed testing.
  6. If you expertise crashes or glitches, return into your BIOS and enhance the voltage

Monitor CPU Temperature

  • You also needs to monitor the CPU temperature when working the stress take a look at.
  • Don’t let the temperature cross 100°C. Also, be certain that the temperature doesn’t transcend 85°C on regular use (with out stress take a look at).
  • If temperature stays excessively excessive, lower the overclock settings to the final secure values. You want more environment friendly cooling choices like customized water loops for larger overclocking.

Test and Repeat

Continue altering the settings and tweaking them as wanted till you discover a secure overclock. With Manual Overclock, I may elevate my AMD Ryzen 7 1700 processor’s frequency from 3.0 as much as 3.7 GHz. If I had a greater cooler, I may most likely elevate it past 4GHz.

You can then run benchmark checks and file the enhancements within the CPU efficiency.

Note: Since the precise steps for altering the CPU Frequency and Voltage differ for various motherboards, I like to recommend checking our devoted guides if you happen to want further assist.

Extra Tips


After enabling CPU overclock, you may as well allow XMP to your RAMs within the BIOS to spice up your system efficiency even additional.

If you additionally need to overclock your GPU, you want to use particular OEM or third-party purposes reminiscent of MSI Afterburner.

Also, any sort of overclocking will have an effect on your CPU well being. So after overclocking, it’s best to do the next issues to extend CPU lifespan as a lot as potential.

If you need to disable handbook overclocking, reasonably than manually reverting the settings, it’s best to reset your BIOS altogether.

Also, updating BIOS whereas enabling overclock could result in system instabilities. So be certain that to disable the overclock beforehand.
