just an FYI, the note in the first post about checking the power limit for 130% isnt absolutely true. it might still be beneficial to flash this new bios.
I have an early 2080ti XC Ultra here (11G-P4-2383-KR, SN starting: 18....), and PX1 reported that it had the 130% max PL. but it was underperforming in benchmarks compared to my other 4 2080ti XC Ultras, and the BIOS version was different than that of the BIOS in the OP.
Flashed the BIOS with the new version anyway, and boom! performance came back in line with the other cards, PL remained unchanged at 130%.
