ellovp - have you tried 8 x GPU setup.
I am thinking of doing this using 3 to 1 PCI riser on the 6th PCI slot.
That should get the MHs above 200MHs per rig.
Thoughts?
I am going using Claymore Dual miner for this rig.
thanks
I haven't tried with my nano's, i have tried to use a pci hub/splitter in the past, i still have 2 of them though.
Maybe i'll play with them again sooner or later.
But like it is now, 6 per rig is more than enough

+ i would need an extra PSU.. nahh i'm fine like this :p
I have EVGA 1600w G2, and I will work on the 8 x GPU version (246MH/s rig!!!) - I will post results soon.
I am still waiting for DHL to knock on my door...
I don't think you'll have enough PCI power connectors to connect all 8 Gpu's.... "could be wrong though.."
Anyhow, even if you do, the psu won't be able to bring enough power to all those rails. "again, could be wrong.."
I tried latest driver 16.5.2, still the same behavior. May I know which driver are you using?
Try to boot with only 1 nano connected to your mobo and see what that gives you

You may right on the number of VGA cables, I need to check the PSU later tonight otherwise this 8 GPU monster even using the mod will need 2 x PSUs because of lack of cables points.
