All Graphics Cards or Discrete Video Cards come with their own BIOS which contains all the important settings for graphics cards regarding fan speed, clock speed, voltages etc. Generally graphics cards do not require BIOS update unless you are facing some serious issues like unstability, freezing, compatibility issues or other technical issues related to GPU. Also if your graphics card is voltage-locked and you want increase the voltage of the card for overclocking purpose then you have to install a custom or modded BIOS on your graphics card. Graphics Card BIOS or GPU BIOS is also known as VBIOS, Video BIOS or VGA BIOS.
Updating or Upgrading Graphics Card BIOS is not that hard but you should be very careful in updating VGA BIOS otherwise you might end up bricking your graphics card and render it useless. There are separate special tools available for both Nvidia and AMD graphics cards for GPU BIOS update. Here in this post I am going to list down the tools that you can use to update the video BIOS of your graphics card.
Reasons to Update VGA BIOS of Graphics Card
Here the various reasons that may prompt you to update the VGA BIOS of your graphics card.
Stability Issues – If you are facing stability issues like artifacts on screen or monitor, frequent freezing, BSOD, crashing or restarts due to graphics card then you can try and flash the VGA BIOS of your graphics card to solve these issues.
Heating Issues – Sometimes a faulty or buggy GPU BIOS can cause unexpected heating of your graphics card even when the card is on stock frequencies. This is because the fan speed settings and temperature throttling settings might not be working properly on your current BIOS. In these circumstances you may try and update the GPU BIOS to fix these issues regarding overheating of your GPU.

You can check your graphics card model and current VBIOS version using graphics card information tools like GPU-Z and then look for the correct BIOS on the graphics card manufacturer website or on other reliable website. After finding your GPU BIOS, save to your hard drive. The BIOS file generally has the .ROM extension to it.
2. Download BIOS Update Tools
Now download the BIOS update tools for flashing your graphics card VBIOS. For Nvidia graphics card you have to download NVFlash and for AMD graphics card you have to download ATIFlash to update your VBIOS.
3. Backup & Update your GPU BIOS
Now make backup of your current VBIOS using these GPU BIOS Update tools because if anything goes wrong with the new VBIOS then you can safely roll back to your older VBIOS.

For Nvidia Graphics Cards [NVFlash]
nvflash [options] <filename>
For AMD Graphics Cards [ATIFlash]
atiflash [options] <filename>
4. Test the New BIOS
After successfully updating the BIOS or Firmware of your graphics card, you can test it by overclocking and by playing games to see if everything is working normally or not. If you encounter stability issues or unexpected rise in graphics card temperature then you should roll back to your older VBIOS that you have saved earlier in step 3.
Updating graphics card BIOS or VBIOS is pretty easy and safe if you do it correctly. Generally graphics cards do not require BIOS update unless you are an advanced user or enthusiast who want something extra from the graphics card, or you are facing some serious issues with your graphics card.
