I was having an issue where the xoc bios' in the first post would fail to flash on my ftw3 ultra (3842 3987), I have a 0.1v 2114 card.
This guy seemed to work for me: EDIT: lol I don't have enough posts to links, but techpowerup dawt com /vgabios/231617/evga-rtx3090-24576-210329
119% power limit, rebar enabled, confirmed it actually hits 500w, hope this helps someone.
