    Hello,
    I am using Ethos and would like to run claymore with 6 gpu
    hope someone could point me in the right direction here (please !)
    You have to believe me here when i say that i have tried absolutley everything
    i have read here but i just cannot get 6 gpu working with this motherboard.
    With Claymore each gpu is at least 2 mh/s faster
    With ethminer i can run 5 stable(3 days)
    with both sgminer and claymore's the 6 gpu will start up and hash at 27 or so and the cut down to 4
    after 1 or 2 minutes.
    With sgminer it also does me the courtesy of telling me that the 2 gpu are sick then dead.
    This can be with any card in any slot,it always changes.
    I think somehow that that is the important part ?
    All cards and risers work fine and have been checked in different slots,different risers,individually,
    in groups and any combination you can think of.
    All the info on here i can find i have followed.
    So that's 4 gpu with claymore and sgminer,
    and 5 with ethminer.
    This is my first build and i have really enjoyed it so far,im looking forward to making more hopefully.
    but i have now been banging my head against a brick wall for 2 weeks now(starting to make a mess)
    Anyway i hope someone here has a clue for me.
    Cheers
    Provide more information about your setup: makes, models, versions, parameters, screenshots, troubleshooting steps taken...

    Sorry i forgot to post this bit:

    Operating system:Ethos
    mobo:Z170A GAMING PRO CARBON (MS-7A12)
    ram:4g
    Intel(R) Celeron(R) CPU G3900 @ 2.80GHz
    drive_name: KINGSTON SV300S37A120G
    GPU: 6x XFX rx480 8g one of which is the gtr black edition.
    PSU: Corsair hx1200i


    I have the same PSU, GPUs and CPU... Different MB and Win10. 6 cards in each rig. I have Z170 MB which I use for testing. If I have a spare time I might try to run 6 cards on it. If I were you I would try to seriously downvolt and downclock the cards, let us say half speed, to make sure that this is not related to current, voltage and temperature. If 6 runs with minimal speed than you can rule out drivers, OS, power and etc. I have seen comments that Z170A are the most problematic when it comes to 5+ cards. Have you tried another mobo?

    Thanks, i put them down to half speed and its been running for over a hour now at a stable 13 mh/s per card ,
    What would you recommend next,slowly increase ? i dont have another motherboard to try.
    thanks for your help

    Well. It tells that you do not have issues with drivers, risers, OS limitations. Focus on the power and temperature. Raise Fan speed to 70-80. Do not overclock the cards. Keep them downvolted (970-1000mV). Slowly increase Core clock and Mem clock.
