can you show structure MISC2 in bits like RAS CAS MISC above, thanks.
2  Alternate cryptocurrencies / Mining (Altcoins) / Re: RX480 (Reference) 31+Mh, Custom Rom on: August 24, 2016, 03:51:34 AM
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.
