Thank's for this very detailed guide.
Many seem to have successfully updatet they rigs.
I've tried for two days now with different drivers, changing slots etc.
Never get it running.
Whenever the modded card is plugged in, Win10 gets frozen or so.
Is it possible it does not work with Sapphire RX480 Nitro+ ?
The reference BIOS will not work with the Nitro+. You need a modded Nitro+ BIOS, which I have, as I did my 6 cards.
But it's not great. For some reason the Nitro+ cards will ignore VDDC set below 1v, it essentially bottoms out at 1v and I have to use MSI AB or similar to get it to go lower. Nearly all the cards will run with VDDC of 0.89v at 1125MHz core speed. Sio much power saving to have, just not via the BIOS. Not sure if it's a card or driver issue preventing the BIOS setting VDDC lower than 1v. My reference card doesn't experience the same problem.
Also, I'm finding very few of my Nitro+ will do 2200MHz on the RAM like my reference card, so for safety and stability I have RAM set to 2125MHz, this still get's it over 29mh/s per card.
I'll look to share the BIOS later if I remember.
Hey Walrusbonzo.
You're basically setting VID's and not VDDC, in this case, as i have the same cards, you should add a global VDDC offset "8D".
This way the voltage controller will start calculating those VID's from a lower starting point. Which has better results
