For example, overclocking an Intel Core i7 that normally runs at around 2. However, if you know what you are doing and have the correct cooling methods in place, overclocking will not pose as a problem. Each individual CPU is different regardless of whether they are the same model number from a manufacturer.
Overclocking will ultimately give you a decent boost in performance, especially if you edit lots or photos or do a lot of video transcribing.
For full instructions on how to overclock your CPU then refer to guides from your manufacturer. Take a look at our full range of CPUs here. We use cookies to do things like remember what you've added to your shopping basket and show you content we think you'll be interested in.

This is the menu that you will be spending most of your time in, as it will allow you to adjust the CPU speed as well as the voltage it receives. In order to help prevent the memory from causing errors, you'll want to lower the memory bus before continuing.
Lower it to the lowest possible setting. The base clock, also referred to as front side bus or bus speed, is the base speed of your processor. It is typically a lower speed that is multiplied to reach the total core speed. For example, if the base clock is MHz, and the multiplier is 16, the clock speed is 1.
Run a stress test. Start up your LinX and run it through a few cycles. If there are no problems, you're ready to move on. If your system is unstable, you may not be able to get much performance out of the overclock, and you should reset your settings to default. Increase base clock until the system becomes unstable. This will allow you to find a sweet spot much easier.
Run a benchmark every time you make an adjustment until you reach an unstable state. The instability is most likely caused by the processor not receiving enough power from the power supply. If your motherboard does not allow you to adjust the multiplier, then you can skip down to Part 4. If you can adjust your multiplier, then move on to the next section to try to get more gains.
Make sure to record the settings you are currently at, in case you want to return to them later. Part 3. Lower the base clock. Before you start increasing your multiplier, you're going to want to lower your base clock a little.
This will help make your multiplier increases more precise. Using a lower base clock and a higher multiplier will lead to a more stable system, but a higher base clock with a lower multiplier will lead to more performance. Finding the perfect balance is the goal. Once you've dropped your base clock a bit, start raising your multiplier in 0. The multiplier may be called "CPU Ratio" or something similar. It may be set to "Auto" instead of a number when you first encounter it.
Reboot your computer and run your benchmarking program. If your computer doesn't encounter any errors after a few runs through the benchmark, you're good to raise the multiplier again. Repeat this process each time you increase the multiplier another increment.
Keep an eye on your temperatures. Make sure you pay close attention to your temperature levels during this process. You may hit a temperature limit before your system becomes unstable. If this is the case, you may have reached the limits of your overclocking ability. At this point, you should find the best balance between increasing the base clock and increasing the multiplier.
Repeat until limit is reached and the computer crashes. You should now have settings that just barely cause your computer to become unstable. As long as your temperatures are still within safe limits, you can start adjusting the voltage levels to allow further increases. Part 4. This may be referred to as "Vcore Voltage". Raising your voltage beyond safe limits can quickly damage your equipment, so this is the most finicky and potentially dangerous part of the overclocking process.
Every CPU and motherboard can handle different voltage increases, so pay extra close attention to your temperature. When raising your core voltage, increase it in 0. Any more and you run the risk of jumping too high and damaging your components. After your first increase, run a stress test. Since you left your system in an unstable state in the previous section, you are hoping for a stable stress test run. If your system is stable, make sure that temperatures are still at an acceptable level.
If the system is still unstable, try lowering either the multiplier or the base clock speed. Return to either the base clock or the multiplier section. Once you have managed to make your unstable system stable through increasing the voltage, you can go back to increasing either the base clock or the multiplier, depending on which you are trying to overclock.
Increase them in the same small increments, running stress tests until your system becomes unstable again. Since the voltage settings increase temperature the most, your goal should be to maximize the base clock and multiplier settings to get the most performance out of the lowest voltage possible. This will require a lot of trial and error and experimentation as you try different combinations.
Repeat the cycle until a maximum voltage or maximum temperature is reached. Eventually you will hit a point where you can't get any more increases, or your temperature is nearing unsafe levels.
This is the limit of your motherboard and processor, and it is likely that you will not be able to progress past this point. If you reach your temperature limit before you hit a voltage limit, you may be able to eke more increases out by improving the cooling system in your computer. Part 5. Back it down to the last safe settings.
Lower your base clock or multiplier down to the last working settings. This is your new processor speed, and if you're lucky it will be noticeably larger than it was before. As long as everything boots OK, you're ready to start your final test. Increase your memory speeds. Raise your memory speeds back up towards their initial levels. Do this slowly, stress testing as you go. You may not be able to raise them all the way back to their original levels.
Save your settings and reboot the system. To give it a bit more juice, find the CPU voltage setting. By default, it usually is set to 1. Increase this value slowly , for example to 1. This gives you a bit more room for overclocking, so you can try increasing the multipliers a bit more. But every time you overclock a CPU, your computer runs hotter. So make sure you have proper cooling! In this example, I gradually increased the clock speed from 3.
Doing so improved the Cinebench score from to an insane 1,! Cinebench CPU test results before overclocking. Cinebench CPU test results after overclocking. Without overclocking, you might need to pay hundreds of dollars to achieve a similar speed increase! Resetting the BIOS reverts all settings to their default values, so you can try the last setting that worked for you.
In the worst case, you can pull out the little battery on your motherboard, wait 10 seconds, and put it back in. Refer to your manual for more instructions. Overclocking allows you to run your processor at higher clock speeds than originally intended. This lets you do resource-intensive tasks faster and more smoothly, such as editing videos or photos or gaming.
Generally, overclocking makes your computer feel snappier. In the example above, we went from 3. If you want more performance, be it for gaming, rendering, coding, or simply for your day-to-day tasks, you can try to achieve a higher core clock. That saves a lot of money compared to the cost of upgrading to a new CPU or even a new computer.
An overclock can give you more frames per second in many scenarios. To make sure no software or setting is slowing you down, check out our guide on how to speed up your PC. If the clock is set too high, your PC will simply reboot or bluescreen. For more on that, including our recommendations, check out our article on how to build your own gaming PC.
