Resizable BAR is now available on all RTX 30-Series GPUs

Nvidia announced this morning all its GeForce RTX 30 series graphics cards are now compatible with Resizable BAR. Whether you have an RTX 3090 or an RTX 3060 Ti, you can get some extra footage of your favorite game.

The company is working with Intel to have its GPUs communicate directly with Intel processors, which avoids sending information to DRAM and speeds up the communication process. This is what makes this small increase in frame rate possible. Now is also a good time to announce its Resizable BAR expansion; Intel officially launched its 11th generation desktop processors today, and combined with its new Adaptive Boost technology and Nvidia’s other AI frame rate boosting technology, DLSS, these are three ways to get more performance from your hardware.

According to Nvidia, users can expect a 5.9% increase in fps Cyberpunk 2077, an increase of 7.2% Forza Horizon 4, and up to 11.9% increase in other games at 1440p resolution on ultra. However, based on our previous testing with the same AMD feature (called Smart Access Memory), the feature is game-based, so it ‘Potential users of games won’t see a boost in every game they own. Nvidia claims its resizable BAR only supports 17 games in total so far, including the two mentioned above.

Resizable BAR is compatible with Intel 400- and 500-series chipsets, as well as AMD 400- (with Zen 3 support) and 500-series chipsets. When it comes to processors, Nvidia’s new feature supports Intel 10th and 11th generation processors and AMD 5000 series processors. Asus, ASRock, Colorful, EVGA, Gigabyte, and MSI motherboards support Resizable BAR.

In addition to making sure you have compatible hardware, you will also need to update your motherboard BIOS and GeForce GPU to the latest firmware and driver versions. RTX 3060 Owners already have the latest version, but for everyone the driver update you need depends on what kind of card you have. If you have a Founders Edition of the RTX 3090, 3080, 3070, or 3060 Ti, you will need to get your VBIOS update from Nvidia. For those with partner cards, you can find the update on that company’s website.

To enable Resizable BAR, load it into your PC BIOS at startup, click Advanced settings > PCI subsystem settings > activate Decoding greater than 4G > then activate Resize bar support. These names must be the same for all motherboard manufacturerss, but recheck your manual just in case.

Nvidia enabled Resizable BAR on its RTX 3060 GPU last month. We were waiting for the company to enable the feature on the rest of its graphics cards to begin our benchmarking tests. NOTow it has, we can’t wait to dig.
