Hi everyone,

A new miniZ version v1.9z5 is out with many new improvements and features.

Performance improvements for AMDs mining 125,4 / 144,5. Up to ~10%, depending on GPU and OCs!

Added better support for fan control, --gpuoffset/--memoffset options for NVIDIA GPUs (Linux).1

Please find miniZ version v1.9z5 Download page.

miniZ version v1.9z5 is out!



  • AMD improvements 125,4 up to 10%, depending on GPUs and OCs.
  • AMD improvements 144,5 up to10%, depending on GPUs and OCs.
  • Added --fanspeed-all/--fantemp-all options to set fan control for all GPUs. *
  • Added --fanmax option, works only with --fantemp. If not used fan max is 99. *
  • Added --power option to AMDs, on Linux.
  • Better AMD fan control on Windows. * 
  • On Windows, added support for fan control for all nvidia drivers. *
  • Added --gpuoffset/--memoffset options for NVIDIA GPUs, on Linux. (1Will only work if there’s a Xorg running with a configured GPU.)
  • Added fan core/memory clocks, and speed information (%) to Telemetry.
  • Added support for RX 5500 and AMD R9 390. (Feedback is welcome.)
  • Fixed fee getting stuck in particular conditions related to network issues (unstable, unreliable…).
  • Fixed --ocX on ethash.
  • Fixed UBQ stale share on start.
  • Fixed Worker name that was not consistent, on ZergPool.
  • Fixed 144,5 broken kernels.
  • Removed LHR kernels.

* Requires sudo (Linux)/administrator privileges (Windows)
Note that fan control options do not always reset on exit: might keep the speed it had when the miner exited, or set then fan to 0, depending on the driver.
We keep looking at this. Let us know how it works for you. 
When using --fanspeed conjointly with --fantemp, the fan % defined with --fanspeed works as minimum fan speed.


*** Thank you all for the feedback! ***

Remember to try --oc1/--oc2/--ocX options for optimum performance. (NVIDIA only)

      Hi Fix 6950xt,
      Thank you for the feedback.

      Try adding --mode 21 to your command line.

      If you have doubts using --mode, read the FAQHow to use –mode?.

      Let us know how it goes.

    Please add option to restart the miner by minimum hashrate. And option to reboot the PC after N-times miner restarts

    • alex says:

      Or it already exist, иге I just couldn’t find it?

      • miniZ says:

        Hi Alex,
        You can try --cutspeed for miniZ to exit on a hashrate defined by you.
        --cutspeed=20,10,35 values are min speed /gpu.
        Probably it will not help much because if the GPU crashed miniZ will not be ablet to exit. Let us know if this works for you.

        Regarding option to reboot the PC after N-times miner restarts, we’ll think about it.
        Thanks for the suggestion.

        • alex says:

          Unfortunately the –cutspeed option did not work, although hashrate dropped to 0 on one of the cards. But just restarting the miner and the card works again as if nothing had happened before.

          • miniZ says:

            Hi alex,
            We cannot replicate the issue with --cutspeed.
            Could you please paste here your command line?
            Maybe also the miniZ output, when it doesn’t exit.
            Thank you.

    I ask for help, when I overclock according to your recommendations on the 125.4 algorithm, then my LA value rises sharply. Give a recommendation what to do? P106-100 Cards
