hi guys
i have RX470 4GB Sapphire (Elpida EDW4032BABG · 113-7E353FU-M78)
os: hiveos
OC: core1126 with 800~810MV   memory:1900
miner: teamredminer 
coin: RVN
i got 13.5 MH for GPU with 57C with fan 50~60% with 80-85 watt report on hiveos
(if i increase memory to 1975 i have 14.5 for each card but temperature goes up and not idle for me)

any suggestion for better hash with lower temperature?

thanks for your great opinion
