Good guide and I've been scrambling around trying to get my speeds over 25MH ETH + 730MH sia per card(dual mining with Claymore V10) but have struggled.
Currently running rig of 6X RX480 Sapphire Nitro+ Elpida. New blockchain driver and and using Anoraks Memshift Bios. When I tried using the Overclock Bios it would trip out my 1200w rig after it started dual mining but it achieved around 27MH.
Also is it important to DDU and reinstall blockchain driver every time? Can't I just run Pixel patcher?
It's better to use DDU, but if you don't change voltages it should be fine not to do that.
