im doing 950 on my rx 570s, also on rx 580s on v7, thank you for the srbminer i think when you implement failover pools if you havent already and do some tweaks this will be a number 1 cryptonight miner
what are your overclock settings?
my rx 570 4gb are doing a lot better than my 8gb ones. but the highest hashrate I can get is 850. anything above crashes the miner...
