That's an interesting discovery. Is that what causes the 'random' disconnects? Connected directly to Nicehash I'm getting 0.2% dead time due to socket errors, but on MRR it was 25-30%.
I can't match cast's hash rate with stak either, although its closer than 25% for me. >1950H/s per card on cast or ~1800H/s on stak. When I was doing Electroneum stak would get a better average rate on the pool and found more shares than cast, but Nicehash doesn't care - it just wants more H/s.
Also, although cast will happily run both cards with one executable, it is definitely faster running one per card instead, by 50-100H/s for the same power consumption. Stak doesn't show the same difference though. Running two instances of cast reduces hash rate drop due to disconnects too as the cards hardly ever disconnect at the same time so even if one is idling, the other is still running.
Just need more of them now!!! There are a couple of Sapphire 56s on ebay for £650 but I'm not paying that for used ones when Scan say they will have the Red Devil in at the end of the month for £600. No sign of the French ones yet.
