since the fork i am only getting 200h/s per card when mining Sumokoin, used to be 450 hash . rx550 2gb hynix.
*I know the hash is suppoed to be lower since the fork but not this much lower right?
Heavy uses more memory so you'll probably have to dial back intensity quite a bit. I haven't yet tried this myself because the CN coins I primarily mine have foolishly delayed switching to an ASIC resistant algo...
So, I have my RX 560's churning away on MUSIC (Ethash) instead.
