I have the following problem. I have several r9 280x from Sapphire and Asus. My cards deliver only between 13-14 Mh / s. The Rig`s run under Win 8.1. AMD driver is 15.12 and the miner is the Claymore miner. I have already tried a lot but I come to no solution.
has someone an idea for me? Would be very grateful.
PS: I come from the schweitz .. excuse me my English
