Yeah... Should've checked that before buying it. How could I miss that2080TIs made in 2019 (I believe) use XUSB and are not compatible with earlier cards. Unfortunately, most of the high-end PL BIOS are from older cards. I'm not sure if there are any higher power-limit BIOS' made for XUSB cards, maybe someone else knows.
Been checking thru some other vBIOS, maybe one of these is a good bet?
They are both for non-reference PCBs so I'm not feeling too confident..
