Resize Bar

103

I've attempted to turn on the Resize Bar feature, and my rig meets the hardware requirements (10850k, ASUS z490-e, Asus RTX 3070 Ti). I navigated to the PCI Subsystem Settings in UEFI, but only found SR-IOV Support listed. I don’t see Re-Size BAR or higher decoding options. Could someone assist me in activating this? I assume I have the most recent drivers installed, updated via Armory Crate.

Occasionally you must turn off CSM to make those configurations visible. Verify whether it hides the re-bar or 4G decoding choices in the BIOS settings.

I've already turned it off. No success.

Have you verified your BIOS version supports resizable BAR (1003 or newer)? Updating BIOS in Windows isn't very dependable, so unless you've already updated within the BIOS, I can't assume it is. In practice, on a Nvidia card, resizable BAR doesn't offer a significant speed boost, so it's not worth stressing over unless you notice differences. It's curious that this feature isn't present.
