Hello,
I have a rig with 6x Gigabyte G1 RX480 4G with stock mode 1290/1750 in core/mem.
Running in latest driver 16.9.1
and seem i have a performance problem with those cards.

In stock mode, those cards only product ~580 H/s when mine XMR, and ~22 MH/s with ETH.
I knew that is the same with other cards in stock mode.
So we need to do some custom to make it runs with better performance, ~700 H/s in XMR and ~29 Mh/s in ETH
But seem i have no luck.
Firstly those cards is not a reference version, so i cant not use the ROM like RX480-30MhOTB.
I tried with gigabyte oc guru ii but it don't work except of it can turn-off the led lights like i want.
And seem only Wattman can to be used for modify the core/mem.
I tried with many changes, crash, restart but the speed can't boost-up.
Please guide me what i can do !
(In details please because i'm new in overclock)
Thank you in advance!
