This VBIOS update (v5) is offered only to solve issues that may have emerged after an earlier update. If you successfully installed the previous VBIOS (v4) and have no issues, then there is no need to update it.

NVIDIA Resizable BAR technology gives a system’s CPU direct access to the entire GPU frame buffer. Multiple CPU to GPU transfers can be made concurrently instead of being queued, leading to a performance boost for memory-intensive games and workloads.

To enable Resizable BAR, please ensure your system meets the following minimum requirements:
1、Intel 10th Gen or AMD Zen 3 CPU
2、ASUS motherboard BIOS is updated to support Resizable BAR
3、System uses the latest NVIDIA VGA drivers
