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 ?

Try this one Marvell, 29Mh otb, low power usage


Greetings
thanks Marvell1 and Eliovp!
I have HIS rx 480 custom 8gb. Can I to use this room for it?
thanks very much.
No need to thank me Eliovp did all the work

btw I figured out the why I was getting such a low hash rate dual mining, this ROM is so efficient you have to set a powerlimit of +10 or +20 in claymore or via wattman to force the cards to pull more juice
I was using around 3.5 (17 amps at meter then when mining 19amps sometimes 20 is how I got this number)  amps for six cards to mine. 

With the powerlimit set +20 and I see a solid 4 amps maybe sliggtly more for six cards which is still fine since I'm getting the following results :

175 or so eth and 2k SC  , solo eth was 181 eth and 3.5 amps so its a bit better to lose 6 or so eth to gain 2000 SC or DCR.

What I did find is these cards will take as much juice as you can give them so be careful I saw rates as high as 490 SC and 28 Eth
