Red Devil Rx 480 Crashing/Freezing on every Modded Bios

[parshuram]

Hey! 

Some of my Red Devil are running at 29 Mhs while 6 of them are not accepting any modded Bios at all. They run only when on Original Bios.   

I have tried pretty much every Bios available - Anoraks, Eliovp, Boysie, Jukebox, custom made. 

Any ideas or inputs please?

Also each Rx 480 Red Devil running at 29 Mhs are consuming around 160 W at the wall including the risers and all(excluding mobo). I have tried undervolt via Polaris Bios Editor but looks like the card By pass all the voltage settings.

Any Kind of suggestions , help - I'd be grateful?

Thank You


Ps - If modded Bios - the cards are stable at 30-31 Mhs and 70 watt on gpu z - I can pay if essential for the Bios !
