The Nvidia control panel fails to recognize resizable BAR display.
Your resizable bar isn't showing in the NVIDIA Control Panel despite having it enabled in BIOS and a fast GPU. Check your motherboard settings, ensure drivers are up to date, and verify that the display resolution matches what you're using. If issues persist, try resetting BIOS or consulting ASRock support.
Verify two points: CSM should be turned off in BIOS. Rebar needs this setting to function, and it seems ASRock BIOS allows enabling Rebar without disabling CSM. Make sure you're using a recent enough VBIOS that supports Rebar—some older cards won't work. Of course, the performance boost on Nvidia is minimal (3-5%), so it probably isn't worth the extra effort beyond 20 minutes of troubleshooting.
With my 3090 and ResizableBAR installed, the problem persisted even though BIOS settings were correct. The Nvidia control panel didn’t recognize the ResizableBAR feature. The solution was updating the recently released vBIOS for ResizableBAR. I also needed to refresh both the card’s vBIOS and the Quiet/Performance vBIOS. If you have a 3070, you might encounter the same issue—perhaps a simple vBIOS update would resolve it.
You're looking for a method to update your GPU's VBIOS on an MSI 3070. Since the official MSI Center doesn't provide this feature, consider using third-party tools or manufacturer-specific software to perform the update. Check the GPU manufacturer's website or contact their support for guidance.
You're checking the BIOS settings on your motherboard. It could be Legacy, UEFI, or both depending on your system configuration.
Your UEFI motherboard BIOS is current after the update you made yesterday.
