Nvidia introduces Resizable BAR support on RTX 30 series laptop GPUs and RTX 3060

Nvidia has added support for Resizable BAR on RTX 30 series laptop GPUs and RTX 3060 desktop graphics cards. Support for the remaining Nvidia RTX 30 series cards will come in late March.

Owners of RTX 30 series laptops and RTX 3060 desktop graphics cards will have to install the latest Game Ready Driver (461.64) to benefit from Resizable BAR, a compatible CPU, motherboard and BIOS updates are also required.

Currently, AMD CPUs and motherboard chipsets supporting Resizable BAR include the Ryzen 5000 series processors and AMD 400 and 500-series motherboards. Regarding Intel platforms, supported CPUs include the 10th Gen Core series, as well as 400-series chipset motherboards. Motherboard manufacturers supporting Resizable BAR include Asus, ASRock, Gigabyte, MSI, EVGA, Gigabyte, and Colorful.

Unlike the RTX 3060, the remaining RTX 30 line-up doesn’t support Resizable BAR natively. To enable Resizable BAR on other RTX 30 desktop graphics cards, users will have to download and flash a new VBIOS to their graphics cards. The VBIOS is scheduled to release in late March.

To make sure Resizable BAR is turned on, open the Nvidia Control panel and click on “System Information”. In the “System Information” window, under the “Details” tab, look for “Resizable BAR”. If it’s turned on, it should say “Yes”.

KitGuru says: Do you already have a laptop equipped with an RTX 30 series laptop GPU or a desktop RTX 3060? What kind of performance do you expect to gain by turning on Resizable BAR?
