My problem is with cryptonight normal v7, my 560s are capped at 540-550 h/s, i'm editing elpida/hynix straps with "some" knowledge but i can never pass the 540 h/s although the memory does that with 1950-2000 mhz, whatever i do to the timings, i cant seem to pass 550 h/s even with core to 1230 mhz (1150 mhz on 16CU 560 and around 1900-2000 mhz silicon lottery on memory, always gives 500-550h/s) I don't get 550s cause they are roughly almost the same cost! and they cnat mine ethereum or ethereum forks even with 4gb of memory cause of the compute limitations.
