    Is the L3 and L3+ the same as far as using this tool? 
    Unfortunately all I have are L3+'s, so I don't know.  If they are using the same pic, the answer is yes.  If you have one and want to try, it will tell you if it doesn't find the same pic version.  The L3 version expects a pic software version of 0x03, the A3 version expects a pic version of 0x81 and uses a slightly different protocol.

    Hey all,
    I took the work that jstephanop did for the L3, cleaned it up a bit to make it easier to script with (there is a quiet mode which just outputs values).  I then added support for the A3 based on the work that FNT did.  We now have a single program that will work with both the L3 and A3 (don't have a D3 but it may work on that too).

    At this point I would call it pre-release since although I have tested it on my L3's and A3's, it has not had a lot of testing.  Some of the changes I made include timing changes in theory to make it faster, so I would be interested if you are seeing any error messages at all. 

    Like any of this stuff, use at your own risk. Shocked

    Code and binary are here: https://github.com/darval/bitmain-tools

    @jstephanop @FNT
    If you guys want to merge all this into a single repo, I am good with that.  Take a look at the changes I made and see if you see any issues, or are interested in merging it back into your versions. Smiley

    Is there a compiled version for A3 or is the compiled version of v3.2 from L3 + suitable?

    The compiled version in the release above works with both L3+ and A3.  There is a flag 'set_voltage -l' for L3+ or 'set_voltage -a' for A3 that tells it which machine you are using it on.  I could change it to autdetect but I figure you know what machine you are running on and I didn't to use the wrong protocol in case it caused unexpected side effects.

    Does it work on the L3?
    error on L3 (not L3 +)

    root@antMiner1:/config# ./set_voltage 1 D0
    -sh: ./set_voltage: Permission denied

    p.s.
    figured out
    -
    how to turn off the fans (maximum speed) when rebooting?

    Thank you!! I'll try later. You need to run through - Mining Rig Rentals? With 0xa0 undervolt you need to reduce power? Will there be no problems?

    I found a easier way and it makes it perm set.

    The blizz firmware worked flawless with voltage settings but the dev fee sucked. I did some testing and digging and found out how he changed the voltage inside his firmware.

    He changed the values of the gpio drivers to 1 for lowest setting of voltage. I also found once you set the voltage to 1 inside his firmware it makes it perm set inside the miner reguardless of what firmware you use.

    I converted mine over which is working fine. I'm at 700 watts at 384Mhz on all my miners now.

    Steps to do this.

    1. Installed blizz firmware.
    2. Goto global settings and Change the voltage to the value of "1" do not use lowest because then it will reset voltage back to 10 if new firmware is loaded.
    3. Flash default antminer firmware back.
    4. Check temps you will notice the temps about 10c lower which means its working.

    No dev fee, Lower Wattage and lower temps.

    Also the settings stay in the miner period forever.

    Blizz and I use the same way to change the voltage...it flashes the PIC controller's voltage offset which persists on the actual hash board (its not inside the linux controller). My tool does that exact same thing, without needing to flash his firmware, change the voltage, and flash back...not sure how that is "easier" :p

    I guess it makes sense if your that scared to learn 3 command lines and need a GUI to do it.

    EDIT: I found the solution, it's even on page one, but I'm leaving this here as it would help other new folk for you to add that to the instruction post, and it should definitely be in the github readme. Otherwise, good work, it works well. Smiley

    ORIGINAL PROBLEM:

    Posted this to the github as well, but sharing here too:

    Tried running script following README and not found. CPed the file to match the command name (copied version removed the _new.c) and result was this:

    ./set_voltage: line 1:/: Permission denied
    ./set_voltage: line 2:/: Permission denied
    ./set_voltage: line 3:/: Permission denied
    ./set_voltage: line 4:/: Permission denied
    ./set_voltage: line 5:/: Permission denied
    ./set_voltage: line 6:/: Permission denied
    ./set_voltage: line 28: static: not found
    ./set_voltage: line 29: static: not found
    ./set_voltage: line 30: static: not found
    ./set_voltage: line 31: static: not found
    ./set_voltage: line 32: static: not found
    ./set_voltage: line 33: static: not found
    ./set_voltage: line 34: static: not found
    ./set_voltage: line 35: pthread_mutex_t: not found
    ./set_voltage: line 36: pthread_mutex_t: not found
    ./set_voltage: line 40: syntax error: unexpected "("

    All of the above said, at 475 freq it helped me shave 2-3 degrees off per card, which is well worth a $20 from me, donating now. Well done!

    great work buddy! So that means this should work on D3s too? Has anyone tried this jstefanop's tool on D3s?

    Hi
    Window user here, Never used command line that much in my life, but with several tiral and error I made it.
    Its easier then it look.

    Figured it out. Also 0xfe is not the lowest its 0xff according to blizz firmware.

    But the set_voltage wont allow that setting

    Make the same for the z9 mini, because new batch of miners since September does not work in the dispersal, only at 600
    probably because of the voltage

    Great work!  I wish I had seen this back in May  Sad

    Currently running 425 freq which is 555Mh/s and only pulling 760W.  Only getting about 8 - 10 HW errors per hour and my nonce HW error is about .03%

    Fans are set to 30% which keeps me under 50 on all bards.

    Had to set all of my volatges to f0 since fe kicked out too many HW errors.  Sending some LTC your way in thanks for saving me some money!

    Great work mate! Please can you take a look into Z9 mini as well? They changed something from Batch 1 to Batch 2 and now we cant OC them any more. They must have lowered the Voltages as the machines become unstable :/

    Hello All!

    Does somebody have  last version of binary  from darval:    set_voltage_new    (v0.3)   which can work with 16f1704 in both protocols?
    I didn't find it on github.

    Pls, put here or in PM.
