How to overclock Intel i5 7400?


Have you ever wanted to overclock your intel i5 7400? Overclocking an intel cpu can be confusing, but it is pretty simple with this guide.

Intel makes some of the best CPUs out there, but they are still limited by default settings. Exceeding these limits is called overclocking . Overclocking is done many ways, including by BIOS, software, or even physical parts. A good approach with most computers is using the bios. However , that usually requires restarting into a special mode where you can change the bios settings properly. That takes time and patience . And time isn’t always something we have too much of when playing games with our friends online- especially not if they’regy! On top of that, restarting the computer is annoying.

If you are not techie person and don’t like to overclock your CPU, that’s fine – it is totally safe. You can also take Auto Mode if you want, which will allocate the maximum performance your processor can give (and more) during certain tasks.

The i5 7400 comes with 6MB of cache memory which is 3 times more than the entry level products from AMD have. This means a much better response time while opening programs or booting up your device – no need for long waits anymore! Furthermore, the Core i5 processors have a high clock frequency of 2.8GHz which cannot be ignored in today’s world where speed has become an essential part of every task we do on our PCs!

A little more about the i5 7400’s specifications; it has two cores and four threads which is pretty good for daily office usage. The TDP rating lies at 65W which is not really a lot – plus, if you’re buying this piece of technology then you are probably considering other components that have a much higher TDP rating than this one! And its Sockets Supported lies at 1151 which means it will fit in all motherboards based on the 1150, 1151 or 2011-v3 sockets.

Yup. Pretty cool, huh?

Well, after reading all of these amazing features I’m sure your thoughts are now revolving around how much does this baby cost? Well, fret not my friends because this particular CPU can be bought for an amount not more than $200! I know, right? Pretty much affordable!

Instead, if you have an Intel Core i5 7400 , i7 7700 or i7 7700K , there’s a much easier way of overclocking it without restarting . This can be done with ThrottleStop, which is free to use on any computer.

How to use ThrottleStop to overclock Intel i5 7400?

Step 1: Installing ThrottleStop

Install the necessary dependencies by opening a Terminal window and typing:

sudo apt-get install libncurses5-dev libpci-dev libglib2.0-dev Build the program files by typing:

cd /home/user/Downloads/ cpupower -r  (note that there are two ‘p’s in ‘cpupower’) make

ThrottleStop is now installed under /home/user/Downloads/ThrottleStop

Step 2: Showing your CPU Configuration Information Open ThrottleStop with root permissions by typing sudo ./Throthrottlestop or using graphical user interface (GUI) gksu throttle stop


In the main ThrottleStop window, you will see a list of tabs on the top. Click on CPU and GPU

You will then be presented with an overview of your CPU and GPU information. You may notice that some features don’t have a green light next to them, which means they are not being used. For example, on my laptop, Turbo mode is disabled as you can see by the red X under the CPU Core Voltages heading:

The Turbo Mode is necessary for your CPU to reach its maximum speed. In order to overclock your CPU from 2GHz to 3GHz, we need this option enabled so go ahead and enable it by clicking on the blue box next to Enable Turbo Mode . Once Turbo mode has been enabled, you will notice that the blue light next to it turns green, indicating that it is active:

After enabling Turbo mode, I noticed that my CPU temperature went from 85 degrees C to 97 degrees C. At this point, it’s probably a good idea to find a way to keep your laptop cool so go ahead and open MSI Afterburner . In order for ThrottleStop to work correctly with Afterburner, we need to have Afterburner running in the background so I suggest going over to the General tab and setting Afterburner’s Profile Selection Mode option from Automatic Detection back down to On Screen Display . This should solve your overheating problem.

What makes this method so nice?

All one has to do is look at the graphics showing you what frequencies are being used by your CPU . It also shows temperatures and other crucial data that will allow you to optimize performance- not just based on speed but temperature, power usage etc. Since it runs right next to windows in the background, access is quick and easy – no need for restarting every time you want to change something.

The i7s and i5 can both be overclocked by around 20% and the difference will definitely show in different tasks that you run on your PC, such as rendering or gaming.

What to do after you have overclocked your CPU?

It is sometimes said that overclocking your CPU will make it perform better and more efficiently by running at a higher clock frequency than it would conventionally. However, this comes with some risks such as overheating (and thus decreasing the lifespan of the chip) and possibly even rendering your computer useless.

Intel processors use thermal paste to conduct heat from the die of the processor to the heatspreader of the cooler which dissipates heat away from the processor. If you try and overclock without applying appropriate cooling then you run the risk of frying your processor and expensive repairs! The best way to cool down an Intel Processor is via water cooling but if this is not practical for you then fan cooling may be just what you need!

In order to overclock your Intel CPU it is essential that you apply appropriate cooling. The best way to do this is via water or fan cooling however if this isn’t practical for you then just using the stock cooler may be enough in most cases.

  • Firstly, decide whether overclocking is right for your machine. If your computer is relatively new then overclocking may not be the best idea – chances are that most games won’t even run fast enough on your machine to warrant overclocking! On the other hand, if you have a slow computer or one which struggles with heat issues (eg laptop computers) then overclocking could make a world of difference.
  • Secondly, you will need to know what settings can be adjusted on your specific Intel Processor. These are typically found using CPU-Z, by checking the ‘Overclocking’ tab. This will allow you to see what voltages are available to be adjusted on your processor. If your computer starts automatically adjusting hardware settings (eg voltage) then an increased chance of your machine being damaged may exist.

If overclocking is right for you and you have decided which settings you would like to increase, make sure that it is stable enough before applying larger overclock settings – this will reduce the chances of breaking things! This step is very important as an unstable overclock can cause either crashes or damage to your machine! The best way that I have found to test its stability is with Prime95 . If any errors are detected then reduce clock speeds slightly until you are able to start testing again.

Once you’ve found the maximum stable overclock, if your machine is not currently being used for more demanding tasks then I recommend setting a CPU frequency governor via cpufrequtils . This will allow you to manually set the frequency that it uses when running applications that require high performance (eg games). To reduce power consumption at idle simply override this frequency using cpupower whenever possible.
