Just click. "One click timing patch"

and now Paste the 1500er Memory Timings (Straps) to all higher frequences (1625, 1750, 2000) of Automatic.

Powersave ( reduce wattage to 90/100w = Rx470 / Rx570 and 100/110w = Rx480 / Rx580 )

Go To Powertune
https://i.hizliresim.com/1JEabB.jpg
Set the original Values down to 100 TDP(W) and MAX POWER LIMIT(W) 120

MAX POWER LIMIT(W) is by Most cards 120W Standart, this is the Sapphire Bios here it is by 160W set it Down to 120-140.
Other Cards Like Powercolor Red Dragon, Asus Expedition, MSI Gaming X etc runs with 100-120Watt setting in Max Power Limit (W) stable!!!

Overclocking ( Set Rx470 / Rx570 up to 27-29 MH/s, Rx480 / Rx580 4GB up to 28-30 MH/s and Rx480 / Rx580 8GB up to 29-32 MH/s !!!

Here you Set Gpu Core Clock in last 5 States @1075 Mhz @1065 Mhz @1055 Mhz @1045 Mhz @1035 Mhz
Maybe your GPU had a better Chip and Runs @Higher Clocks, Try it ! I use RX 570 4 GB now here.

Go to Memory

https://i.hizliresim.com/G9DWlV.jpg

Here you Overclock the Vram ( Video Memory )
Most Rx470 / Rx570 makes 2000Mhz
Most Rx480 / Rx580 4GB makes 2000Mhz
Most Rx480 / Rx580 8GB makes up to 2150Mhz
Have Rejects or falling Hastrate after Moddifying try Lower Clocks like 1950MHz
