Folk,

A question has come up on how to tune Z9 and Z9mini with the per hashboard feature. Here is a small writeup(copied in the original post now) that hopefully will explain:

To tune for best frequency

1) Set global frequency to 650. Set each other frequency to "Use Global".
2) Observe your boards for at least 10 minutes, if any drop out, on the next cycle decrease their frequency by 1 step in the pulldown.
3) Repeat this cycle until you have a stable minimum frequency for your boards.
4) To start the 'upwards tuning', choose one board (#1 for example) and increase it's frequency by 1 step.
5) Observe the board for at least 10 minutes to see if it is stable. If it is, repeat #4. If it is not, drop down 1 step and move to the next board.

Going through this process (which hopefully makes sense), you should be able to tune your units for your individual system maximums. It's best to do this with the fans set to 100% so you can remove thermals from the equation -- after which, set the fans back however you want them and see if your boards stay stable. If they do, good, of they don't, eithee decrease freqeuncy by 1 step or increase fan.

Please do note that sometimes a lower frequency produces a higher hash rate, so be mindful of that as you select for your environment.

Thank you,

Jason

Hi Jason.

Installed your firmware on z9mini. It works fine, but I see that the problem with the nicehash has not been solved. Still, I hope that in the future you will be able to solve this problem.
Asic connected to hiveos
Also, everything works fine, except for one thing: the Niveos interface does not correctly display the statistics of the set frequencies on the asic. I contacted the programmer hiveos. He said that the statistic firmware is not displayed via the API, but is read directly from the config file. Therefore, in the interface Niveos shows the statistics data is not correct.
Can you fix this?

Thank's.
