Problem is resources on mobo and how the bios manages it! Title: Re: TB250-BTC PRO not seen more than 4 gpu Post by: Johny101010 on August 18, 2017, 09:02:18 PM 2 things:
1. Check to make sure you are using mining Mode UEFI unless you are using a custom Linux distro. 2. And most importantly check your risers. Usually, in every pack of 4 you have a bad one. That will screw up the whole setup. Title: Re: TB250-BTC PRO not seen more than 4 gpu Post by: Cereberus on August 18, 2017, 09:21:34 PM This fix is easy. As long as you see 5 GPU-s recognized although with exclamation mark it is no problem. I have already advised to many persons to do this and the majority of them have been successful.
Download DDU(Direct Display Uninstaller) google it. Uninstall the driver/s of all cards completely. Reboot. Download and install the latest drivers from AMD website. Also you better change every PCIE to Gen1 and not Gen2 from Auto.
