AMD RX 560 515 h/s for Cryptonight (Monero, Electroneum..) @ 40 watt on the wall

I built my first Cryptonight rig a few months back using Sapphire Pulse RX 570 and was able to get 915 h/s @ 95 watt on the wall. Due to high prices and unavailability of RX 570s, I decided to give RX 560s a shot. I am glad to mention that I am able to obtain 515 h/s @ 40 watt on the wall for AMD RX 560 while mining Electroneum/Sumokoin (will be true for all Cryptonight coins e.g., Monero, Karbo).

I am using sgminer-gm 5.5 with rawintensity 416 and worksize 8. The trick was to use 2 gpu threads in the config file as follows:

"rawintensity": "416",
"worksize": "8",
"gpu-threads": "2"

My GPU is Asus OC 2gb Polaris 14nm 1210 Ghz core and 1750 Mhz memory clock. It uses Elpida DDR5 memory. Its bios is modified using Polaris 1.6.6 editor's one click patch option and that was pretty much it. (I tried Sapphire RX Pulse 4gb version but could not get it above 410 h/s).

I tried Crimson Beta 17.30 Blockchain driver but it kept on crashing. Finally managed to make Crimson relive 17.7 work.
