Hi guys, I played a little bit around with the verions for the mod L3+ https://bitcointalk.org/index.php?topic=3546316.0https://bitcointalk.org/index.php?topic=3835841.0and made my own version of voltage regulation for the Antminer A3. (tested) As the D3 has the same kind of boards, PIC, etc... this also works on D3. Programm can be downloaded at https://forexneurotrader.com/AD3_MOD_FNTYou can also use the script to download and set permission at the miner here: https://forexneurotrader.com/AD3_MOD_FNT.shlogin (Putty) to the miner and type: curl -k -o AD3_MOD_FNT.sh https://forexneurotrader.com/AD3_MOD_FNT.shand then set permission for the script with chmod a+x AD3_MOD_FNT.sh and the start the script with ./AD3_MOD_FNT.sh it starts to download the files and set permission and start the program. Then you can set the voltage of each chain or set it to all. Normal voltage is 0xb8 at A3. If you like the programm and you save some money, may you send me a donation. BTC: 1593z3zwpmCEiKf7EeXzKx799nR25NWpxD If you have any questions, just ask. Maybe I can help. Bye, FNT PS:the source -> https://github.com/ForexNeuroTrader/A3_D3

You're going to need to release the source for anyone to install this on their miner.

Nice work, what type of power draw reduction do you get 10-20% less then the stock power draw A3 - 1275 watts (815Gh). D3 - 1200 watts (19.3Gh)?

Will probably help reduce the heat too because these things run hot. I will gladly try it once I see the source code.

If you can release a new a3 firmware with these voltage settings id happily pay 1.5% dev fees.

nice work!! i am not sure how low we can set the voltage since the default is already at 0xb8... the lowest we can go is 0xfe. I think Bitmain already pushed this chip to the max.

really good work. Can you also compile it for Xilinx? It will be really helpfull with S9...

i try it on a D3 and works fine just need to tune it and works really good
i dont have how to test the power usage before and afther but the heat reduce a lot

Hi guys, yes, it can sometimes happen, that you get an read error on the I2C bus, and the you get an error message. No problem at all, just start the program again -> ./AD3_MOD_FNT -> read all voltage settings. @racebyu: haven't tested/measured power reduction so far, as for me temp. of chips and of course lower fan speed! and lower noise is main topic, I was able to reduce chip temp. about 8°Ĉ-10°C @shaninium: you don't need a new "firmware" for this, as you can set the values in the PICs memory (it's the microchip which indirect regulates voltage) and the the values are stored in the PIC of each hashboard.

you broke the script dude... it was good but now all it does is download and set permision not set the voltage this happend when i want to chance voltages root@antMiner:~# ./AD3_MOD_FNT.sh 1 b9 change dir to /config start downloading file... % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 13668 100 13668 0 0 14972 0 --:--:-- --:--:-- --:--:-- 19525 Download done, setting permission Start programm... Reading all voltages chain 1: voltage = 0x74 chain 2: voltage = 0x74 chain 3: voltage = 0x74
it always do that...

it always do that... Hi! Please be aware, that the .sh is the script for download, etc... and it does what it should so far. If you have done this (used the .sh script) please use/type cd /config and then ./AD3_MOD_FNT 1 b9 without the .SH Bye, FNT

Any recommendations for voltage settings on the A3 at 600 frequency?

Yes, this can happen, I also had this problem. After a cold start -> power off and power on the miner, the error is gone and the I2C controller and miner is working again. Bye, FNT

Hi Dude,
I am getting still this error:
tried it on A3 - Got message ... root@******:/config# ./AD3_MOD_FNT.sh Reading all voltages
version = read ERROR 1 Wrong PIC version root@******:/config#
I have tried change just one chain but 3rd try I have got this error and cannot read config and change config.
I have tried restart miner, restart putty and do whole procedure as in your first post.
Also tried upgrade firmware for whole antminer but I cannot see status of mining anymore.
Also from "Overview" tab is missing "CGminer Version" value (in gui of Antminer).
Any ideas?

Hi! No idea... sounds strange, do you have an error log of the miner? (programm in this mode is only reading!) Bye, FNT
