Is it possible to set each AntMiner U2 at different clock. I purchased some used ones. Two of the used U2 show there age and do not want to run at 2.0 but will run at 1.8 same with two older U1 they will only run at 1.6. If I try to set them anything else x0881 and x0781 respectively they hit about 30% hardware errors. I have tried the following config file but it seems to read and use the last antminer:clock=.
