Title: NVIDIA Resizable BAR Firmware Update Tool
Post by: JeGX on March 30, 2021, 05:17:43 PM
This article explains how to update the GPU firmware for Resizable BAR compatibility on GeForce RTX 30 Series GPUs from NVIDIA and our partners. Contact your GPU vendor if you have further support questions not covered by this article.

Resizable BAR is an optional PCI Express interface technology.  NVIDIA has created a downloadable GPU firmware update tool for GeForce RTX 30 Series GPUs to enable Resizable BAR.  The tool will detect whether a firmware update is supported, and if supported, will give the user the option to update it.

Enabling Resizable BAR requires a compatible CPU, motherboard, system firmware (SBIOS), R465 or higher driver, as well as GPU firmware (VBIOS) support.  Updating the GPU firmware should only be performed if the rest of the platform supports Resizable BAR.
