I'm sorry for dedicating an entire post to this troubleshooting issue but I've spent an entire day frustratingly trying to figure this out and I have exhausted all the resources I have found online

I've tried so many different BIOS settings and I can't get more than 9 GPUs working on this board.   Has anyone else found a working solution?

I have tried the f1 and latest BIOS versions.  I have the two molex cables connected to the mobo (not sure they are necessary with power risers).  Turned off mining mode, enabled 4g encoding. tried gen 1, 2, and 3 and also tried turning off the 24-119 entries in combination with each gen link speed.  With the latest version of the BIOS I could post with gen 1 link speed but windows wouldnt load (or it loaded but the screen was just black).  I couldn't even load more than 6 GPUs on the latest BIOS, aka when I connected the second PSU it wouldnt post.  

Anything else that I missed?
