xfx black RX570 4gbs with elpida..not time to play yet,but first shot with 1200/2000 975mv and some other small changes with power limits.. has been stable 7-8hours @29.9mhs..GPU-Z says 83-85watts.. used a custom strap from my xfx black 470s, i found it on the custom timings thread here.its faster by 1mhs then the stock 1500. will let you know how far i can push them...my asics are from 74-88 mixed.
