Unstable, Gigabyte Mobo, GTX 1070

[Miich94]

Hey all,

My Specs are:

Intel Celereon G3930
Gigabyte GA Z170 Gaming K3
8GB DDR4 RAM
60GB SSD
6x MSI GTX 1070 ARMOR OC
1200w Corsair

Problem:

When i bought my last GPU, i connected it, pc wont boot normal, it goes do the second bios automatic i think so there is some failure?
I cant find the problem, and its only when i connect 6 GPU's does anyone here runs the same motherboard with 6 GPU's?
When u use 6 cars, the MH\s is bouncing up and down. from 30mhs to 15->8 and again up. How is this possible? i tried everything with Afterburner current settings are:
Power Limit 70% Mem Clock +700, it was all the time stable with 5 cars, disconnected differed cards if there was a problem with the 6th card but nothing.


And atm. i am using Claymore dual miner
Driver version 384,76 because windows did it automatically
pool: Ethermine, Sia Nanopool

Check your bios settings I think you need to do something in there for PCIE enabling.................................
