I don't have that specific motherboard; but I have other z97 mobos with similar 6 GPU difficulties. I will get one out and see if I can find the problem tonight.

To help me find the problem:

press f12 to open the guake terminal

If cpuminer-opt is running rightclick over the guake terminal and select new tab or press ctrl + c to stop it.

then enter:

lspci | grep VGA

please tell me what this outputs

00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller (rev 06)
01:00.0 VGA compatible controller: NVIDIA Corporation Device 1c02 (rev a1)
03:00.0 VGA compatible controller: NVIDIA Corporation Device 1c02 (rev a1)
06:00.0 VGA compatible controller: NVIDIA Corporation Device 1c02 (rev a1)
07:00.0 VGA compatible controller: NVIDIA Corporation Device 1c02 (rev a1)
09:00.0 VGA compatible controller: NVIDIA Corporation Device 1c02 (rev a1)

lspci doesn't see the GPU because the riser wasn't plugged in on boot. If it was plugged on power up and boot, would get error 55 and the system wouldn't even boot neither would get any video or interaction, hard reset is the only option there. The problem is not in the riser or GPU or slot because this is happening on all 5 rigs (z97x and 1060), replacing risers, GPU or power cables doesn't help.

I'll try now to leave it past the bios and then plug in the sixth riser on GRUB choose.

What happens if you disable the onboard graphics?

So I just got my 1st z97 mobo to work with 6x GPUs; it is not the same model as yours; but yours might have a similar setting that needs to be changed.

I had to change the setting called: DMI Gen2 Speed from Disabled:

to Auto

in order to get the sixth card to work properly.

I have 1 more z97 mobo; I'll try it as well.
