I'm struggling to get this motherboard to detect 6 GPU's. I have successfully gotten 5 working properly, but not 6. Yes, it's a mining rig. On attempting to add the 6th card I immediately get a 55 error on the motherboard error code display. It was confusing at first because I thought I shorted my RAM with static charge or a similar event, but it turns out the board came back up after a CMOS refresh.

I can get 5 cards detected and fully working with windows by setting the MAX VLOUD setting to 3.5. I'm no entirely clear on what this does.
I have attempted to set the pcie gen setting to 1st Gen in all the available lanes 1,4,6. I'm unsure why it doesn't give this option for the 3 other lanes. I have turned off everything possible to partition resources to PCIE, such as disabling onboard audio, com/ethernet, 3rd party USB, and ps2 support.
I can get 6 cards detected in Windows 10 Pro 64bit, but 3 of the cards display an error claiming "it can not gain enough resources, etc).
Can anyone help me with settings to achieve this? I spent more on this board assuming it would allow this level of control for my application of mining.
If not can anyone in support definitively tell me the board will not support 6 GPU's.
I have booked marked similar threads such as http://forum.asrock.com/forum_posts.asp?TID=3250&KW=z170+gpu&PID=15906&title=z710m-oc-formula-pcie-lane-speeds#15906.
