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?

Huh

Try and set pcie speed to GEN2 in bios
IF it dosent help, Try enable Above 4g decoding.
IF it dosent work try to update bios to H22
Try go to peripherals in bios and set mining mode enabled.
