Hi all, I have a new rig and I've tried all the tricks in the book but my cards are stuck at 22mhz. I've tried all the different crimson drivers, re-installed windows, did DDU, updated the BIOS, tried different version of claymore, modified afterburner config and still nothing. In afterburner if I try to overclock memory past 1900 i get blue/white screen and even if I go less than 1900 my hash rate decreases from 22 to 19. Any suggestions how to fix this? I am trying with rx480 4gb on windows 10 claymore 9.3 and crimson 16.9 (but have tried other versions).
Try the newest AMD drivers (I think 17.3.4 or something like that) and then use them using the Pixel Patcher (Google for it). I am using the newest drivers patched and they are hashing well. Are you sure you used a modded ROM for the memory type in your card. The memory used in the cards can change from run to run. So a mod for your card for one memory type might not work properly or has well if you have another memory type in your card. Check out youtube videos from cryptomined and others. They have lots of good information about modding, putting together rigs, etc. It also might be an issue with the BIOS on your motherboard. Some just do mine well. Make sure your motherboard BIOS is the latest available for your board.
