Head to the manufacturers’ website to discover whether your motherboard is compatible, and to download and install updates if available. Additionally, please refer to the manufacturer’s documentation for enabling Resizable BAR support in the BIOS after installation of new firmware.

To successfully activate Resizable BAR on a desktop PC, please follow these steps in order, referring to the expanded installation instructions below:

On the bottom left of the Control Panel, simply click “System Information”, and in the new window look for “Resizable BAR” on the right. If it says “Yes”, you’re set.

For GeForce RTX 30 Series Founders Edition graphics cards manufactured by NVIDIA, please head to our knowledge base, where you can download the firmware update tool, follow how-to instructions, and get further information. If your system does not support Resizable BAR there is no benefit to installing the firmware update, so please check you meet all other requirements first.

With the release of our GeForce Game Ready Driver on March 30th, 2021, we’re enabling Resizable BAR support on all GeForce RTX 30 Series GPUs, and expanding support to an additional 9 games, for a total of 17:

Firmware updates for custom GeForce RTX 30 Series graphics cards manufactured by our partners can be found on their websites. The links provided below are for your convenience only; partner hardware vendors are responsible for functionality and support of GPU VBIOS updates:

Before proceeding further through the Resizable BAR process, please download and install the latest GeForce Game Ready Driver, released March 30th, 2021, or later, and reboot your PC.

Please note, some motherboard manufacturers have unofficially extended Resizable BAR support to prior generation products. Your mileage may vary utilizing these solutions.

In practice, the performance benefits of Resizable BAR can vary substantially from game to game. In our testing, we’ve found some titles benefit from a few percent, up to 12%. However, there are also titles that see a decrease in performance, so NVIDIA will be pre-testing titles and using game profiles to enable Resizable BAR only when it has a positive performance impact. That way you won’t have to worry about bugs or performance decreases, and won’t have to rely on the community to benchmark each title and discover whether Resizable BAR is beneficial in the games you’re playing.

After you’ve updated all your components and installed our Game Ready Driver, you can verify Resizable BAR is working on your system by opening the NVIDIA Control Panel.

AFTERPAY total order limit is $1999. If you wish to purchase an item where the shipping added is over this amount please contact us.

If an update for your specific model is not yet available, do not install the Founders Edition firmware or other custom firmware as it is not compatible.

Resizable BAR requires CPU and motherboard compatibility, and a Resizable BAR SBIOS update. As of March 30th, 2021, the following CPU chipsets and CPUs officially support Resizable BAR on GeForce RTX 30 Series desktop GPUs:

Having updated your motherboard, you’ll need to update your GPU, and download and install a GeForce Game Ready Driver, released March 30th, 2021, or later.

For desktops to take advantage of Resizable BAR, users need a GeForce RTX 30 Series graphics card with a supported VBIOS, a compatible CPU, compatible motherboard, motherboard SBIOS update, and our newest GeForce Game Ready driver.

NVIDIA is working with motherboard manufacturers around the world to bring Resizable BAR support to compatible products. As of March 30th, 2021, the following manufacturers are offering SBIOS updates for select motherboards to enable Resizable BAR with GeForce RTX 30 Series desktop graphics cards:

Resizable BAR utilizes an advanced feature of PCI Express to increase performance in certain games. As of March 30th, 2021, Resizable BAR is supported for GeForce RTX 30 Series graphics cards and laptops.

With the ever-growing size of modern game assets, this results in a lot of transfers. Using Resizable BAR, assets can instead be requested as-needed and sent in full, so the CPU can efficiently access the entire frame buffer. And if multiple requests are made, transfers can occur concurrently, rather than queuing.

Resizable BAR is an optional PCI Express interface technology. As you move through a world in a game, GPU memory (VRAM) constantly transfers textures, shaders and geometry via many small CPU to GPU transfers.

For GeForce RTX 30 Series laptops, please check with the manufacturer to see if Resizable BAR is supported on a specific model.
