I use PowerColor RX 480 Red Dragon 4GB using Hynix memory.
And after doing some testing I can get 800 H/s for XMR (of course still much below other expert since I'm just newbie).
I use 1266 or 1300 core clock and 2000 memory clock.

I know that still can be modified to get better hash, and if someone can do that please share it with me.
