Did you install the VBIOS update for 3090 to add BAR support?
When running msi live update, there are no updates available. I just got the card yesterday, so I assume since no updates are available that it came with the latest bios.?.?

When gpu z says bios not configured, that would mean mobo bios right? Not gpu? Or could it be either/or.

never trust live update to tell you the right thing go take a look at MSI's website for yourself chances are good there's an updated vBIOS sitting there

Yea, that's the update I have been trying to run, and it says no supported gpus. I downloaded from msi... the zip/executable. then I used live update since that wasn't working, and of course it did not work either.

then you may need to contact MSI's support and ask them what the heck is going on

Yea, did that yesterday and had an idiot reply

Hoping someone there will help get the bios updated. But I am still perplexed on why gpu z shows the mb bios not configured for bar, since I have all the correct settings.

Is that conversation one you had with MSI tech support if so why didn't ask about ReBAR not being enabled in the vBIOS instead of asking about low temp vBIOS, asking about something completely different to what you were looking for is not going to get you the answer you're wanting

*sigh* I have two issues I am trying to resolve. I would like to enable rebar, which led me to this thread. I still have no idea why gpu-z says "
Resizable BAR enabled in BIOS - No," even though I have the MB bios configured correctly, and have updated the MB bios to the latest revision. That has nothing to do with the GPU bios, as confirmed by Wizz.

Secondly, I had already starting working with MSI yesterday to determine why I cannot flash the VBIOS. Because I would like to flash it with a 500 watt bios, versus what it came with stock. I had not even started worrying about rebar at that time... I started working on rebar while waiting for a reply from MSI... I only mentioned that I haven't been able to update the VBIOS because Wizz asked "Did you install the VBIOS update for 3090 to add BAR support?"

I will likely reach out to the MB for support with rebar here shortly, but hoping someone else has come across this exact issue with my mobo and has a fix.

*update* The issue was the VBIOS, which is weird, but FYI for anyone that has this issue in the future. GPU-Z was showing the MB not enabled even though it was. Once I figured out how to update the VBIOS, everything worked perfectly.

For MSI GPU owners, here was the issue. If you download the vbios from their support page, it did not work for me. Would not even apply. I downloaded msi live update, and it was not working there either. But you have to scroll all the way to the right to the bios tab at the very end, and scan for updates there. Not the first bios tab. Once I did that, it downloaded the latest bios and everything worked magically after that.

The Mobo your using has the same bios setup screens as my Strix x570-F Gaming mobo and you're right it does only have Disabled or Auto and I'm pretty sure that with any BIOS that has Agesa 1201 or better should enable ReBar mine has 1202 for the Agesa an shows ReBar as enabled in BIOS so yeah maybe check Asus's website for a BIOS update

Version 3501 Beta Version
2021/04/13
20.36 MBytes
ROG CROSSHAIR VIII FORMULA BIOS 3501
"- Update AMD AM4 AGESA V2 PI 1.2.0.2
- Fix USB connectivity issue

there is a new Beta bios for your mobo if you not running it then maybe give it a go mine seems to work fine which is also a beta bios haven't had any weird crap happening so give it a go it may just fix the problem you seem to be having
