Hello all ! I have a bad situation with one of my rig ! My hdd is bad and i changed it with another one (new). I installed all the drivers but when i start mining with claymore , my GPU only runs with 11 mh/s ! Before this happened they goes with 29 mh/s ( they are overclocked) What is wrong with them ? I tried to copy the bios but they said that is the same bios ... Any ideas ? Thank you in advance !

Sorry for my bad language !
