Does Updating BIOS Improve Performance?

If you are trying to build your new PC, you might have faced several difficulties while installing its hardware. One of the major grounds of challenges is while you want to update your BIOS, which we may long to do so as to expect a good performance boost from the system. Remember that it is definitely important to update the operating system and software of your computer, but then again, you must always be aware of when to do it right!

Learn the fact that BIOS updates with no way make your computer faster or help you add some new features to your system, and thus, you should only be opting for this when you think that it is required to implement the new improvement that you are planning to incorporate! Also, you must be well prepared about the cons that this change might bring to your system, thereby enabling it to get into a lot of unnecessary troubles while conducting its operation.

What is BIOS?

Before we dive deep into trying to figure out how updating the BIOS will enable you to improve the performance, you must understand what it is! Well, BIOS typically stands for the Basic Input / Output System. Your BIOS tends to take control just as you put on the power button. It starts the Power On Self Test or POST and thus, hands over the control of the system to the boot loader.

Further, it helps in boosting the operating system. However, in today’s time, PCs are coming with UEFI firmware over the traditional BIOS which is functionally similar to the same kind of software. In a nutshell, the BIOS integrates all the hardware systems of your PC and thus, you need to get it done for the seamless functioning of your PC build.

What are the Major Functions of a PC BIOS?

The basic functions of your BIOS include:

POST: This is meant to test the hardware of your system and check that there is no error or malfunction observed while booting up the OS.

Bootstrap Ladder: If your OS is efficient enough, BIOS will automatically pass on the control to it.

BIOS drivers: It delivers the basic control to your computer’s hardware.

BIOS setup or CMOS setup: It is primarily a configuration program that will enable you to reset the hardware settings of your system including changing the date, password, and more.

Can You Upgrade Your BIOS Chip?

You can obviously upgrade the BIOS chip memory or replace the existing one with an advanced one in order to ensure that it is compatible with your motherboard. You may either choose to update your BIOS to sort out some existing trouble, or maybe, to add compatibility for some new hardware feature. In most of the scenarios, you might see that your motherboard is calling for an update at the time of installing new hardware.

When To Go For BIOS Flashing?

In case you have built your own PC, you can get to know about your BIOS update from the vendor of your motherboard. You can easily flash these updates on the BIOS chip, thereby replacing it with the new version released by the manufacturer. While you are doing this task, make sure that you are having the BIOS against the model number of the PC that you are using. This is because BIOSes are usually computer specific or motherboard specific and there is no alternative to the same!

There is a good amount of difference between installing a software update to your system and flashing a BIOS. Since you have the scope of facing different problems while flashing from Windows, you might want to flash your computer from DOS. In that case, you will have to create a bootable USB drive with DOS on it and restart the system accordingly. Also, you should be aware of the fact that the instructions for flashing your BIOS vary from one manufacturer to that another!

Last but not the least, you have BIOS flashing tools that are meant to detect if your BIOS fits the hardware. A little mismatch can make the whole system unbootable and it shall turn into a disaster!

How Do You Know that You Should Be Updating Your BIOS?

You must not be updating the BIOS until and unless you have a proper reason to do so! Here are a few reasons that you must go for it:

Hardware support

Motherboard manufacturers usually call for support for their new PCs, particularly when there is a new hardware installation. Also, you might require to update the BIOS when you are upgrading the old CPU of your system to a new one!


You might be able to fix the bugs that are existing in the old version of the BIOS by simply updating it. You may also come to know about this information from the BIOS changelog which you are going to get readily available on the manufacturer’s website, or maybe, learn about it from the tech support provider that you have contacted to resolve the issue.

Considerations to make for not looking ahead to update your BIOS

It won’t help you to improve any performance either! The major reason for you to look for a BIOS update is either to fix a bug or make your CPU compatible. If all the things are working well, do not take the headache of upgrading your BIOS by any chance.
