b350 resizable bar support???

ReBar is enabled in the BIOS, it would seem like it should work, but as you can see, it doesn't.
What are your thoughts on this?

The fact that these settings are even in the bios is crazy, considering it's an old B350 board.
I have seen guys on other forums talking how they flashed B450 bios'es onto B350 boards and etc.

Update:
I changed my cpu to Ryzen 5 3600 and my GPU to RX 6700 and now AMD SAM/ReBar works perfectly with the same old B350 motherboard!
So if you have this or other similar Gigabyte boards, make sure to check your BIOS for ReBar support or update your BIOS.

• • Hey man) I want to ask you something.... I also have a GA-AB350M-DS3H V2 motherboard. But I don't have a REBAR item in my bios. I noticed that your bios version is f52l. I wanted to install it, but this version of the BIOS is not available on their website. Where did you get it? Its your screen...

I have the latest version of f54d, there is no REBAR in the bios. I tried to roll back the old versions, but there is no result. The only thought left is that it's only in your version of bios f52l.

I always install the latest bios available and recheck Gigabyte's website every month or so. I currently run the latest BIOS F54d with full rebar support.

Make sure that Secure Boot, 4G Decoding and Rebar are enabled in the bios.
