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.
