Do not use those basic straps... Almost no added performance and you are not even able to OC.
My RX 470 Elpida has 30MH/s, Samsung has 30+MH/s.

How u did it? I have ASUS RX570 STRIX 4GB modded bios 1500->2000 GPU 1300->1112 Memory 1750->1850 and i have 26MH/s per card stable and 850W power use. How can I do 27~ MH/s per card stability and lower power use?
I have this model (ASUS STRIX RX 570 )
1500->2000 timings
1300 -> 1100 gpu clock
1900 memory clock
I get stable 27.6MH/s with roughly 116W per card
On top of this I undervolt 50-75mv per card and can get to 104W per card stable. (100% fan)
edit: just to add here are my settings in polaris. Note this is just what i've tested and done - it may or may not work for others but it does for me. If you find improvements that you've tested would appreciate replying and sharing.
