Hello everyone, Wasted a day but cannot solve the issue and get stuff working. Set up is the following: - MacBook Pro 15" mid 2012, bootcamp Win 8.1 x64, Nvidia drivers v353.06 (the latest for now) - Gigabyte GV-N970G1 GAMING-4GD (GTX 970) inside Akitio Thunder2 - powered by Akitio power supply + PSU 500W --> 6+2 and 6 to GPU The problem is that Windows cannot enable device, in Device Manager system says: This device cannot find enough free resources that it can use. (Code 12) If you want to use this device, you will need to disable one of the other devices on this system. What can cause the issue? In Mac OS X GTX 970 is not visible in the list however Akitio Thunder2 listed. Any ideas?
