Per the usual not much help around here.

Decided to write my own shiz based off the rx 470

6 GPU @ 166-167MH/s @ 930-950w or so stable

If anyone has a better rom feel free to share.

Anyone have experience with these cards?

Would like to bios mod these cards and see if I can get some better performance, right now just running them stock bios with some overclocking.

Here's my default bios rom saved from Atiflash:

Here's info from GPU-Z.  


Hynix memory.

I'm not sure which values I need to change in polaris BIOS editor.  

Can someone guide me thru modding the cards?
