Hi all !

Its been relatively smooth sailing with SMOS but i have an error i just cant seem to fix. My setup is using claymore v10, mining Ethereum.

I started off about 2 weeks ago with 2 EVGA GTX 1070 cards, mining ~27 Mh/s (not OC)

A week later i saw a sale on a Gigabyte GTX 1070 TI and added it to my rig and got a stable ~26/27 Mh/s

Just now i've added 2 more Gigabyte  GTX 1070 Windforce OC and they both clock in at 14/15 Mh/s

Electrically i've troubleshooted the cards and cannot seems to find anything wrong (ive swapped out risers with other cards, checked PSU connections, etc)

Mobo: MSI 270A-Pro
PEG[0]->tried Auto, GEN 1, GEN 2
Enabled 4G decoding
Disabled HD Audio
Disabled Fast boot and Windows 7

No luck 

I just cant seem to get these cards going , anyone have suggestions or possibly went through something similar?

Any help would be much appreciated ! Thank you
