Cryptonighy-Heavy. 1200+ H/s on RX 570 8gb (Micron). Also, serving as primary display card so couldn't push them too far. Makes my Vega 56 look bad hashing at 1400 H/s 
have left them hashing at 1130 H/s 1250/2200 clocks @ 906mV.

which intensity you used? did you modded your bios with polaris editor one click timing?
56. Dual threads. Not the PBE strap. PBE timings are pretty good too. They do 1080 on similar settings. Haven't tested those at 1400+ clocks
nice strap, can you please share your strap? for me 1250/2200 only got 1110 and with intensity 54. intensity 56 will lower my hashrate. did you try intensity 54? if your GPU can reach 62 intensity I bet it will reach 1200 h/s with 1250/2200.
