I have 3x 3080Ti in my rig and 2 of them now can achieve 73.4 unlock vs 70 previously, but the last one can't even mine with gminer 2.75. No lock detected and hashrate keeps falling down. All 3 cards are the same model from Zotac and have the same BIOS. Have to stick to 2.74, and also really unpleased about devfee increase....
