Getting frustrated..I have a 4 gigabyte 1060 3GB cards, all run around 19.5 on ETH. I picked up some MSI RX 470 Armor 8GB cards and have been tinkering with those now. I can't get the 470s over 20.5 on ETH. I am using crimson 16.6 drivers. I have tried many different settings on afterburner that people have suggested but they don't seem to make an impact at all. I have not modified the bios at all, but these cards should be doing better that 20.5 without a modded bios correct?
