Hi all,

 hoping that someone can shine some light onto a little problemo with a GPU mining rig.

 Specs are;

 Gigabyte Z170 Gaming K3 Mobo
 6 x Zotac NVIDIA GTX 1070 Mini GPU's
 6 x risers
 4gb Ram
 3.3Ghz G4400 Intel processor
 1 x Corsair RM 1000
 
 1 x Cooler Master MasterWatt Lite 400

 Ubuntu 16.04

 Mining with Claymore

 
 The situation is, that the most we can get to work are 5 GPU's.

 Originally we had only the RM 1000 PSU and for love nor could we get the 6th GPU to show in the system (in fact with 6 connected, the system wouldn't boot).

... So, believing it to be a power problem, we bought a 400W PSU but no joy.

 Have tried mobo and all risers on same (400W) PSU, with all GPU's on 1000w PSU and mobo, risers and 4 GPU's on one with the other two Gpu's on the 400w.



 Wtf are we missing?
