:'(Was testing MSI RX580 8GB w/ Samsung memory tonight.
28.9mh/s with
* amdgpu-pro 16.60
* 1150/2100mhz
* Uber Mix 3.1
28.1 mh/s with
* amdgpu-pro 17.10 drivers
* 1150/2100mhz
* Uber Mix 3.1
And not really stable at all.
Not sure why 17.10 drivers cause such a big drop in hash rate.. Started looking at the timings from the 470's with Samsung vs the 580 with Samsung, and all of the timings on the 580 are slower. trfc's and ras2ras are significant
Anyone have any bright ideas as to why?
Finally got it over 30mh. From uber 3.1 strap, I had to bump up trc, trfc, ras2ras, and clocks now 1185/2125, running stable. Seems like the 580's need a bit more core clock, but they do take a better undervolt, so power remains about the same.
