Allready trying... Please say in 1.6.3 on cn-v7 to got max speed need to wait some time? Or max speed is after start?
it should be in a few minutes max, on my hynix 580 8gb cards i get the same hash as on 1.6.0.
Also on 470 8gb.
Don't have samsung 580 8g to try.
What intensity you're use and what speed have?
Straps for ETH, 1150/2050 , 100w from the wall ~ 950hs on v7
56/8/2
yes it can be pushed way over 1000hs but im not looking for that, only using it for testing the miner.
With 1.6.3 the same situation as with 1.6.2... On cn-v7 RX 580 8Gb max speed is 1000 h/s on intensity 108, but not every launch. Miner needs to several starts to get this speed. Waiting up to 5 minutes not helps. Mostly speed is 985 h/s. On 1.6.0 speed is up to 1035-1040 h/s with intensity 116-117.
