I have a similar issue as many others, my card is a 10G-P5-3897-KL (3080 FTW3 Ultra Gaming LHR)
I have managed to flash all of the following BIOS:
4897_LHR_ovu (only 105% PL)
4898 (only 105% PL)
4897_XOC_LHR_ovu (118% PL but doesn't give more than 405W)
4898_XOC_LHR_ovu (118% PL but doesn't give more than 405W)
Each BIOS seems to have an effect, and Precision X1 identifies it as a different card with different power limit, but in practice they all seem to act the same, even with +200MHz set on max vcore.
Does anyone have any suggestion that might work to get an actually higher power limit on this card?
