Rig doesn't boot when more than 2 graphics cards are connected

OliverNChalkOliverNChalk Posts: 3Member
I have been struggling to setup my mining rig, the motherboard I chose is the Strix B250 (Asus) [https://www.asus.com/Motherboards/ROG-STRIX-B250H-GAMING/]. I have 6 * MSI Gaming X GTX1060 6GB cards.
I have a Pentium G4560 CPU and 4Gb of RAM, running Windows. The computer works fine with 2 GPUs (In x16 and x1 slots) however, once I add a third card, it hangs on a blank screen during boot.

Any suggestions are greatly appreciated!

    Using windows I did the following to fix it before I saw this comment:

    1. Set all speeds (PCI-Express etc to Gen 1.0_
    2. Enable Above 4G Decoding
    3. Start with 6 GPU
    4. only 4 showed up
    5. uninstall all drivers and restart
    6. all show up, install drivers
