Running 2.8b, One of my GPU's after finding a share its hashrate drops to 0.0mh, it starts at >30mh then as soon as a share is submitted with that particular card it drops out. I have two models of this card, same memory, both with stable overclock. One runs fine with 2.8b, the other has the issue. I have tried changing my -mi for that specific card lower and the problem persists. Running previous PM versions the card runs fine. Is there a way within the same prompt to individually designate which kernal a specific card runs on? If so is there an example config for my bat?
I had the same exact symptom on 1 of my cards, had to reduce the mem clock from 2215 down to 1175. Not much diff in hash rate, still over 30.
