 I brought up afterburner but do not see how to change the clock speed from 000 to a higher number. I know that if tasks are starved for data (cpu cores busy or low on memory) then the gpu clock will drop as the card is not busy enough to run at 000. There are a lot of possibilities. None of my Linux system show a milkyway problem but they have 00 threads to feed a pair of really slow NVidia 0000TIs where the above systems have total of 0 threads (0 per core) for a much more productive (double precision) Tahitis.
