oh crap... i feel dumb haha

i have p106-90 6GB cards, and from all the googling, looks like i have p106-100 because of the cooler, is there a possible way they got flashed to 90's for low wattage ?

if so, i would like to flash it back to 100's for the hash rate, because they are GTX 1060 equivalent hash is 20-22mh/s and im only getting 12-15mh/s ( gtx 1050ti hashrate )
