Modded VBIOS for RX6900XT/6800XT to work on the MP4,1 - 5,1

[Guest iboffrcc]

Hi and greetings to the members of MacRumors forum,

 

I've read in this forum saying that the Navi21(6900,6800xt) families wont even POST in the MacPro4,1 & 5,1 due to lack of AVX instructions, or there might be something else that cause of this issue.

 

So we are offering to the community - to test modded GPU VBIOS for the RX6900/6800 in hope for it work with our Mac Pro 4,1 and 5,1. Our available GPUs are as follows:

 

-RX6900XT (Sapphire Nitro)

-RX6800XT (XFX Merc)

 

I understand the risks...
