i am still using ver 5.1c on my rx 8gb, still works fine.
my polaris 8gb cards are getting 1 or 1.5 mh/s less after DAG 385 update, I am using Phoenix 5.4c on hiveos. but no reduction in hashrate in GDDR6 card, can u guess any reason for this hashrate reduction with gddr5 card. is the -rxboost not working?
