NVIDIA Resizable BAR Firmware Update Tool

This commodity 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 lot have further support questions not covered by this commodity.

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

Enabling Resizable BAR requires a compatible CPU, motherboard, system firmware (SBIOS), R465 or higher commuter, also equally GPU firmware (VBIOS) back up. Updating the GPU firmware should only be performed if the residue of the platform supports Resizable BAR.

Read our Resizable BAR article to acquire more about supported CPUs, motherboards, GPUs, and games.

Running the Tool

Prior to running the tool, make certain the newest Game Ready Commuter is installed. Ensure power is connected and stable during the update. Salvage open files and practice not turn off your PC.

Once you lot have the tool downloaded, please run the tool and follow the on-screen instructions. When running the tool, a console window will be displayed with instructions. While performing the update, the screen may flicker or temporarily go bare.

A reboot is necessary for the new firmware to take upshot.

The tool will notice all cards in the system and indicate one of the following statuses:

Status

Meaning

Update supported, will exist applied

The existing GPU firmware does non support Resizable BAR, and this tool can exist used to update information technology.

Already updated

The GPU firmware has already been updated from this tool.

Resizable BAR already enabled

The GPU already has Resizable BAR enabled, and no update is necessary.

Unsupported by this tool, contact carte vendor

The existing GPU firmware does not support Resizable BAR, and the bill of fare is not supported by this tool. Contact the card's vendor for support.

Unsupported

The GPU is non capable of supporting the Resizable BAR characteristic. This update is only available for RTX xxx Series GPUs.

If an update is performed, please restart your PC for the new firmware to have effect.

Confirming Resizable BAR is Enabled

After yous've updated all your components, and installed our R465 or higher Game Ready Driver, you tin verify Resizable BAR is working on your system past opening the NVIDIA Control Panel.

On the bottom left of the NVIDIA Control Panel, merely click "System Information", and in the new window look for "Resizable BAR" on the right. If it says "Yeah", y'all're ready.

Additional Information

How do I enable Resizable BAR? There are three components to enabling a higher BAR value.

one. Supported GPU including VBIOS a. GeForce RTX thirty Serial desktop GPUs - Back up for a specific sku determined by GPU vendor b. GeForce RTX 30 Series laptops

ii. Supported Motherboard SBIOS a. Users can obtain motherboard support and SBIOS information from their motherboard vendor b. Within SBIOS, adjust the setting to: 1. Boot in UEFI mode 2. Enable "Above 4GB Decoding" 3. Enable "Resizable BAR" in the SBIOS iv. Disable Compatibility Support Module (CSM) in the SBIOS. five. Ensure GPT partition type is used (and not MBR) a. You can convert MBR to GPT using these guides

iii. Supported driver (Game Ready Driver or NVIDIA Studio Driver) a. RTX 3080 NB, 3070 NB, 3060 NB: 461.forty or college b. RTX 3060: 461.72 or higher c. All other supported RTX 30 series GPUs: version 465.89 or higher

I've walked through all the steps to enable Resizable BAR and I'chiliad still seeing the setting show upwardly as "No" in the NVIDIA Control Panel, or I am getting black screens when booting. What am I missing? Here are three areas to confirm:

Ensure the Compatibility Support Module (CSM) is disabled in the motherboard/PC BIOS
Ensure the boot drive is using GPT sectionalization blazon and UEFI BIOS manner
Additionally, reconfirm the VBIOS updated successfully.

Can I update a multi-GPU system? The updater will detect and update all the cards that tin be updated in a system.

If the BAR value is set to the size of my GPU'south framebuffer (ie: 10GB), does that mean a game volition be using all that (10GB) for BAR? No. The BAR value is used as a cap or ceiling for the full corporeality of BAR that can be used by the game.

Why would I want to change the BAR values from whatsoever is default today? In general, BAR allocations can take a positive touch on performance in certain games.

If the tool is unable to successfully update the firmware, a message will be displayed. Below are potential messages forth with suggested actions.

Message: "An error occurred while updating. Please restart your PC and try again. If the update fails, please contact the card's vendor for support." Proposition: This message may occur if a trouble occurs earlier attempting to update the firmware. Restart your PC and try again.

Bulletin: "An mistake occurred while updating. The GPU firmware may have been corrupted, please try over again without restarting your PC. If the update fails, please contact the carte's vendor for support."

Suggestion: This bulletin may occur if a trouble occurs afterward starting to update the firmware. In this case, do not reboot your PC. The tool should be run again immediately, as the GPU firmware may have been corrupted. If an error occurs again, try to manually uninstall the NVIDIA graphics driver and run the tool over again. If an error still occurs, delight contact the card's vendor for support.

Message: "This tool is for use with add-in graphics cards only."

Suggestion: This message may occur if running the tool on a laptop. Delight contact the laptop's vendor for questions regarding Resizable BAR support.
