ETH Mining Q- 9x 290/380 = ONLY 100mh/s?! Pls help, pics and details inside I'm hoping someone can help me, I bought a fully assembled ETH miner with 6x AMD 290/380 4GB gfx cards. The rig was happily mining at a steady 120mh/s for a year and then things started acting up. First thing that happened was one of the cards suddenly... Bitloverr
