Hi,
following this video:
http://www.youtube.com/all_comments?v=t3iup26oUN4 I installed windows 8.1 for my Gigabyte mobo with 6x Gigabyte R9 270 cards.
So far I have even not tested cgminer, however, having much mroe success as opposed to BAMT SMOS, where only 4 of the 6 GPUs were spinning fans and 2 were recognizes by cgminer.
Now all the 6 spins the fans, and the device manager was initially recognizing just 4, however, I put a dummy plug on one of the problematic ones and put it directly into the slot without a riser. That made the trick and now it recognizes 5, however, the 6 can not be recognized.
I can read at least 3 builds while googling that folks succeeded to get running 6 x R9 270 exactly on Windows 8.1.
However, no one says what exactly he did.
Also what is stranger, the 6th card even did not show in the device manager as "unknown device".
Any advices?
Please, help!
