I have, and since I use Ubuntu 16 I have still not been able to find a way to overclock/undervolt my cards, the thing is that this cards do not have the back up bios switch.
I've tried following the guides here using atiflash/polaris using a USB stick then modding them using a WinPC..
Once I install msdos+atiflash on a USB, the atiflash does not find the cards so I cannot copy the bios so I can edit them.

I've been trying for like 3 weeks now, still have not found a good way.

atiweak/amdconfig/aticonfig doesn't work anymore.

Any help is greatly appreciated it, currently doing 22.5mhz per card

Did you find good Settings for the 8gb Strix RX480?

Hello everyone,

I have made my first rig, I have 5 RX 480 GPUS (there is no more and hard to find any cards now)

I need help in modding their BIOS, if anyone has any recommendations it will be greatly appreciated it,
I am quite new to the modding scene, never done this before,

I'm currently getting 24mhz each.

Thank you
