Resize Bar

[Legomasters21]

I have tried to enable Resize Bar on my rig, which has the necessary hardware to enable it (10850k, ASUS z490-e, Asus RTX 3070 Ti), and I head to PCI Subsystem Settings in the UEFI, yet I only see SR-IOV Support, and not Re-Size BAR Support or Above 4G Decoding. Can somebody help me enable this thing? I believe I have all the latest drivers (I update my motherboard and card through Armory Crate).

Sometimes you need to disable CSM in order for those settings to show up, check to see if that unhides re-bar or 4G decoding options in the BIOS.

I already have it disabled. No luck.

Have you confirmed your BIOS revision is one that has re-sizable BAR suppor (1003 or later)t? Updating the BIOS in Windows is pretty unreliable, so unless you updated within the BIOS I wouldn't assume it is. 

 

Realistically on a Nvidia card re-sizable BAR support isn't noticeably faster, so it's not something I'd pull my hair out getting to work, but it's a bit odd that it's not there.

0607 x64 is what it shows for BIOS version

Well there's your problem, that BIOS revision doesn't support re-bar. 

 

Update to the latest BIOS, then it should show up.

Thanks, now I know I cannot support Armory Crate.
