Did you ever solve this? I'm trying to do have 6-8 cards too and also getting stuck on 5 cards. I found above 4g decoding, but it isn't helping.]]> Fri, 05 Feb 2021 16:35:18 +0000 https://forum.asrock.com/forum_posts.asp?TID=15242&PID=83736&title=taichi-x399-and-more-than-5-gpus#83736 https://forum.asrock.com/forum_posts.asp?TID=15242&PID=81600&title=taichi-x399-and-more-than-5-gpus#81600 Author: manodzit

Hi

Would you be so kind to elaborate on your set a bit more, if possible some pictures would be great!

thanks
