Hello. I need help with configuration of my rig. I have 3x RX 480 4GB and 1 RX 470 4GB. My rx 480 card have 24.7 speed, while RX 470 have 20.7. reading this post i see that it should do much better than that. I didnt overclock my card, and i use standard configuration that we get when we download Claymore miner. Can any1 help me and send me best configuration for my bat file? Thanks in advance. Btw my drivers are crimson 17.3.3.
I believe Claymore recommends the AMD 16.12.2 drivers for the RX 400 series. Perhaps try using those? Use DDU to remove the drivers prior to rolling back to older ones if you do (that can save allot of headaches).

Using those drivers I get ~22 on 4 of my RX 470s, ~24 on 1 of the RX 470s and ~18 on the last RX 470. That's with a small undervolt to lower power costs and heat while underclocking the Core to 1130 and ovcerclocking the Memory to 1950.
