anyone mining with a amd 3x series card?   Why i asked is im pretty sure my 390 8gb  is under performing  gets 680-690  while my 580 gets 1100hashs...   And usely the 390 was always 100hashs lower than the 580 in crytonight  and on other argos like equihashs the 390 has always kick the 580 ass lol..


Using srbminer and i think i tried everything..

Its running on a custom bios so its pretty tweaked  but maybe im doing the settings wrong for it..
