Hey guys,
So far we are having a lot of problems with them. It can only detect 4 GPUs, but we are trying other things to see.
I also saw some complaints about these supporting only 4 GPUs.
I will update my post later with our results, but so far it's shit.
Did you follow the guide at biostar website?
If you are using windows 7 it wont work for 6 gpus, must be windows 10.
