Resizable BAR support has arrived for RTX 30


Keeping its promise, Nvidia introduced Resizable BAR support for RTX Ampere cards. Users experienced an increase in performance with simple steps to follow.

Nvidia has announced in recent months that it will provide Resizable BAR support to the RTX 30 series until the end of March. The firm kept its promise and released the patch in the last days of the month.

12% performance increase

10/11 with AMD’s 400/500 series motherboards with Ryzen 5000 processors and Intel’s motherboards with Z490 / H470 / B460 / H410 chips. According to the tests of Nvidia, the patch that the users of the next generation Core processor can apply in their system provides a 12% performance increase in the RTX 30 series.

On the other hand, let’s underline that the RTX 3080 is estimated to experience an improvement of around 5% at 1440p. RTX 3060 users do not need to make any changes as the cards support Resizable BAR from the very beginning, while the Ampere architecture Founders Edition card users will be able to update the vBIOS with the tool they can obtain for their models from Nvidia’s site. Those who buy the cards prepared by Nvidia’s business partners will need to visit their partner sites.

To summarize the steps, compatible processor / motherboard owners need to update their graphics card driver to 465.89 WHQL and above after updating their motherboard to the BIOS with Resizable BAR if the current version is old.

After the process to be performed with the necessary vBIOS patch tool, the installation is completed by checking whether the Resizable BAR is active with Nvidia Control Panel or GPU-Z. You can review the Resizable BAR supported game list shared by Nvidia below.
