[UPDATE]RX480 (Reference) Custom rom: 31+Mh

VDDC Offset + Basic Custom timing
------------------
Here's a nice update for those who have Reference cards.
In the package included, i've put 4 roms with VDDC offset.

1. -50mV
2. -69mV
3. -81mV
4. -100mV

You can of course adjust these however you want, if you want to have an even tighter undervolt you can search the rom for this --> "8D 00 F8(-50)00" and replace the F8 part with EE(-112) for example.

These roms also have a custom timing included. It's a basic one but it will give you a very high increase for XMR.

Greetings and have fun!

Will be doing more tests later, i'm sure i'll be able to go over 32Mh.
Great thing about this, when i ran the first testrun with stock clocks, card was at around 60 degrees and no abnormal fan speed.

Overall, awesome card Smiley


Power usage tests will follow later when i'm done tweaking my rom to the sweet spot Smiley
