Topic: L3+/L3++ voltage tuning script - page 5. (Read 3421 times)

what kind of results can one expect? we talking 50watt or 5 ?

Sorry found answer in original thread.

Scrypt starts to work, but it finishes randomly testing - sometimes after 10mins or bit more, even if there is room for undervolt for example with zero HW.
And sometime it does this:

I'm running the custom blissz firmware. here the json output:

Basically you set a frequency for your L3+ and then this script tunes the miner to the best voltage settings in terms of optimal error_ratio/power-consumption per board.

Thanks for testing the script.

It seems to fall over while parsing the cgminer json output.
I am a bit at loss, would need to see the raw json output from cgminer.
EDIT:
You could try to add a print statement just before the line it falls over, i.e. before line 95 add
  print json_resp
and post or pm the output.
I have pushed an update to github which should print the json data so we can see whats wrong or where it falls over.
Please update with git pull and post or pm me the output.

Also, are you running the latest Bitmain firmware 1.0.1.3 ?

I am a little green in the ASIC world. What kind of tuning would this do. Apply the best bang for your buck voltage  to each of the cards ?  Does it go for higher hash power, etc ?

Sorry for the newb question. 

Hi !

Tried to use it on one of my miners and got the following log:

/config/sv binary not found on target miner, installing it first:
MD5sum [113ad2c06daac293386e28807ea35671] matches, good.

can you help ?
the script is running on a RPI3

Since jstefanop was so kind to release his demo code for voltage setting on the L3+ we could finally undervolt our L3+ and save some of those precious watts.

Though the process of tuning every hash board is time consuming and boring (at least after the third L3+) and I soon wished there was a way to automate this trial and error process similar to what General Tarkin did on the Titans.

So I hotglued some python script that does the whole process automatically and does not require you to install jstefanops binary on every single miner. But you need a Linux (MacOS might work) machine that can reach the miners you want to tune over the network.

Note: Just to be very clear: The script needs to be run from a different computer than your miner!

If you are willing to try this alpha software, head over to github and checkout my bitmain-tools repo:

https://github.com/psycodad-bct/bitmain-tools

Usage in the simplest form is just:

All options are printed if you supply no arguments to the script:

The script may take anywhere from 30min to several hours or can even refuse to complete if your miner is too unstable. If that happens you can try to use the --skip option to skip tuning one or more chains/hashboards and set them to the best possible value manually.

I did this to save time on tuning and re-tuning my L3+ miners and thought I'd share it here.

Disclaimer:
This script has at best pre-alpha-quality (or even less) and comes as-is with no warranties at all. I have tested it heavily and to the best of my knowledge it should do no harm, but it has obviously when playing with voltages the potential to damage your miner and even if not it will probably void your Bitmain warranty.

Use completely at your own risk!

If in doubt, use the source Luke!
