How to overclock a pc

Overclocking simply means sending the various components of your computer at a higher speed. For example, running a 3 GHZ processor at 3.5 GHZ (or even more). The advantages are clear: higher speed, not only of the processor, but of the whole machine, which vary according to the amplitude of the overclock. The disadvantages are equally obvious: more heat generated, higher electricity consumption, shorter duration some components of our pc. Below we will explain in detail how to overclock on any computer.

Overclocking the CPU

WARNING:   Overclocking could severely damage your hardware, and will in any case grant its duration.

Remember that you are the solely responsible for what you do!


Before you begin with overclocking, you will have to perform a stress test using the basic settings (a program can be found at   this   link). This will give you results to compare with those obtained after overclocking, and will also allow you to notice any problems with the basic settings that will need to be fixed before overclocking makes them worse.

  • Be sure to check the temperature levels during the stress test. If the processor temperature goes above 70 ° C, you probably won't be able to get many improvements with overclocking before the temperature becomes jeopardized. You may need to apply new thermal paste or install a new cooler.

  • If your system crashes during the basic stress test, there is probably a hardware problem that needs to be fixed before starting the overclocking. Check your memory for errors.

If the stress test was successful then restart your computer and enter the BIOS (You can usually enter the BIOS by holding pressed "Canc", F8, F12 or F2).

At this point with the arrows on the keyboard search for the "Frequency / Voltage Control" item, after having found it click the "Enter" key.


To prevent memory from causing errors, you will need to reduce the speed of the memory bus before continuing. You may find this entry with the names "Memory Multiplier", "DDR Memory Frequency" or "Memory Ratio". Set it to the lowest possible setting.

If you can't find the memory frequency options, try pressing   CTRL + ALT + F1   in the menu main of the BIOS.

On the item "CPU / PCIe Base Clock" increase the already preset clock by 10% (For example, if the base clock is 200 MHZ, an increase by 10% would bring the base clock to 210 MHZ).

Finally restart the computer saving the changes made to the BIOS.

Rerun a stress test to verify that everything is working correctly and, if all went well, then the overclock was successful otherwise if the stress test failed it returns all settings as they were before.

Buying RAM at higher frequencies

Another way to overclock your computer is to buy RAM at higher frequencies (as long as they are obviously supported by the motherboard).

Solution and expensive but simple and effective.

Overclocking the RAM

If you don't want to buy them then let's move on to overclocking the RAM themselves.

Enter the BIOS (Usually you can enter the BIOS by holding down "Del ", F8, F12 or F2).

Browsing the BIOS menu, look for an item like" Memory Frequency "or" DRAM Frequency ".

At this point change the frequency of your RAM (Our advice is to gradually increase it, until you reach the maximum value).

Changing the RAM latency

Another parameter on which it is possible to act to improve the performance of the RAM is its latency, that is the time that passes between the request for data by the CPU and the release of these by the RAM.

First download   CPU-Z.

In the CPU "SPD" tab -Z you will find the RAM latency values.

Enter the BIOS and look for the corresponding section. Lower the "CAS Latency" as low as possible and this will ensure a further boost on performance.
