    I couldn’t get the first and last GPU to respond properly to changes I made in the gpu-config.json - file

    I had the same issue - it was the simple fact that I had not disabled my motherboard IGFX graphics card. In order to have reliable results with editing the - nano -w /root/gpu-config.json - file you need to have disabled the internal graphics card so that it isn't counted in the GPU count of cards and which is which.

    Another post on another forum had it nicely worded:

    =========================================================================
    How to Disable the Onboard Graphics in BIOS
    If you have an ASUS Motherboard with UEFI BIOS there is no way you can disable the Intel or AMD Integrated Graphics, however there is a way to specify the primary display. Follow these steps to disable the Onboard Integrated Graphics:

    Enter BIOS Setup.
    Go to Advanced Menu
    Go to Chipset Configuration Menu
    Go to Internal Graphics Menu
    Set the Internal Graphics Mode to Disable or choose PEG/PCI instead of Auto or IGFX. (IGFX means the onboard graphics).
    If you also have a Multi Monitors option set this to disable.

    ==========================================================================
    Once this is done and then you do a
    gputool --update
    gputool --config

    your /root/gpu-config.json file will display all of your GPU's properly and behave as you had hoped for.

    Having done that my ability to squeeze reasonable amounts of hash rates out of a GPU only requires me to do the "1500 timing strap" thing with "PolarisBiosEditor V1.6.7" on their original ROM and then adjust GPU and MEM speeds with the /root/gpu-config.json file followed by a gputool --config to update the speeds to the GPU's. Remember to save backup copies of your original ROM's before you save new versions of them with new names.

    My rigs all have the ASUS Prime Z270-A motherboard and run 6 cars with no problem - If I could buy more GPU cards at a reasonable price today I would add 2 more to these specific motherboards that do support 8 GPU's.

    How did you change the power to 70wt? I thought you can't in Linux...



  • Hi, Im new to mining and was wondering about my the config of my two titan Xp's . Is 40 m/h low for these cards when mining ethe. Should I push them harder is this reasonable?

  • in my json file i have all my cards capped at 150 but nvidia-smi says they are going over, why is that?

    You have to apply the values by running gputool --config



  • @melt I did



  • Anyone have any Ideas? I cant get the fans to adjust to 100 Percent,
    Tried removing the gpu-config.json and rebuilding. Done every step on this page.
    Cannot get the fans to go above 22%
    Any help would be appreciated.

    @jcarpenter

    Hello jcarpenter,

    Could you confirm which miner you are using, as I know for instance with claymore dual in the Flag section that both “—ttstop” and “—tt “ need to be deleted otherwise it overrides gputool settings.

    Best Louis



  • @louis Found the solution, Using Claymore Dual but only mining one. Used the -fanmin to 90 solved the problem. Unit running swimmingly now.

    @jcarpenter

    Many thanks for the update jcarpenter, and glad your rig is running smoothly by adding "-fanmin", great work :)

    Best Louis
