NVIDIA releases driver and firmware update tool for Resizable BAR support

NVIDIA has delivered on its promise to enable ResizableBAR on GeForce RTX 30 graphics cards by end of March.

NVIDIA GeForce RTX 30 graphics cards will now support ReBAR, thanks to the manufacturer’s effort and collaboration with AMD and Intel (as well as many motherboard vendors). ReBAR support requires compatible hardware, the latest driver (456.89+), and graphics card firmware to be updated.

ReBAR on GeForce RTX 30 graphics cards can boost performance up to 12%, NVIDIA claims. Of course, this is just a cherry-picked number that NVIDIA is using for marketing purposes. Gamers however should expect at least 5%+ performance uplift with RTX 3080 at 1440p resolution.

How to enable ResizableBAR on GeForce RTX 30 graphics cards

GeForce RTX 3060 graphics card does not require any changes, this was the only model that received ReBAR support out of the box. Other graphics cards, however, will require firmware updates. If you own NVIDIA Founders Edition, then you are required to download a special tool directly from NVIDIA. Those who own partner (AIC) cards will need to go to their websites and find the tool that works for their graphics cards.

Installation Steps

  1. Confirm you have a compatible CPU & CPU chipset and motherboard (see list below)
  2. Update your motherboard SBIOS, if required, by installing an update from the manufacturer. Then enable Resizable BAR support in your motherboard’s BIOS interface
  3. Update to the latest GeForce Game Ready Driver (version 465.89 WHQL at the time of writing, released March 30th, 2021), or a later version
  4. If you have a GeForce RTX 3060, you’re good to go. If you have a GeForce RTX 3060 Ti, 3070, 3080, or 3090, then you may require an updated VBIOS
  5. If you have a Founders Edition graphics card from NVIDIA, get your VBIOS update tool directly from NVIDIA website. If you have a custom partner card, get the update tool from their site (see list below)
  6. Verify Resizable BAR is enabled in the NVIDIA Control Panel or TechPowerUP GPU-Z
