ok finally got the rom to work, had to do a full re-install of the drivers , copy the modded driver and then boot with option 7
not sure how to get option 7 to auto load on boot.
One issue I'm seeing
dual mining seems quite neutered compared to stock ? at 30 dcri I am seeing 24.5 eth and 360ish sc when before I was getting 23.5 eth and 420 sc
now if I mine eth only I was seeing high hash rates around 31mhs
Also the cards all now detect and 4GB I know others mentioned that as well, it does seem that the core clocks are maxing around 980 which might be the reason for the low SIA or dual mining ?
Which version of the drivers are you using?
Here's what I'm seeing after flashing
