ROG Z390-F Gaming BIOS with Resizable BAR support for Nvidia RTX 30 series cards

Ok, flash was successful, lost all my bios profiles but had a backup.
Got the rebar icon in top right corner of my bios screen. Pointing the mouse at it reveals an on/off menu, which enables both Above 4G-Decoding on my z390-F board, and enables resizesable bar, which is shown in the latest gpu-z.

"edit" It's not more stable for me, my overclock needs minor adaptive vcore adjustments to survive my stresstest. I too came from 1302 bios.
My bios also now lists 8 sata ports, I have only 6 physical ones.

I'm finding this to be the case as well. I was having issues with RAM Training/timings, and the Park suggestions here so far seem to work, as well as manually starting all over after a bios flash.

Actually I think "start all over" is a bit overkill. The main issue with these newer versions seems to be memory related: Training and/or RTL/IOL issues. Those have to be adjusted, together with a few other general adjustments, see my previous post. Pri/Sec/Ter timings can actually remain unchanged.
And after some time now I can state that 1901 is really _better_ than 1302 for me. Running 4013 mem now, whereas 1302 wouldn't do more than ~3950 with identical timings. Only RTL/IO is different, albeit lower than previously! CPU/LLC/vcore is left unchanged, all stable.
So yeah, needs some minor adjustments, but 1901 is actually surprisingly good!
