Hello friends,

I have 5X Sapphire nitro rx480 4gb on win 8 , the latest driver 16.12.2 , no overclock no bios mod.
When start ,all cards run at 220 h/s but after 5 min slowdown to 170-180 h/s.
I try few combinations 1395/2195   , 1306/1900  but no result.The people report 240-250 h/s for those cards.
Can you help me please with proper settings and driver version.

Thank you very much !
