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

Code:

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...

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

Thanks for the reply FNT. Any recommendations for voltage settings on the A3 at 600 frequency?

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.

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,

anyone have try to use it on A3 ?

How much power draw reduction did you get ?

thx

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

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.

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

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

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)?

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

Hi guys,

I played a little bit around with the verions for the mod L3+
https://bitcointalksearch.org/topic/bitmain-l3-voltage-control-toolfree-3546316
https://bitcointalksearch.org/topic/l3l3-voltage-tuning-script-3835841
and made my own version of voltage regulation for the Antminer A3. (tested) As the D3 has the same kind of boards, PIC, etc...
this should also work on D3. (not tested)

Programm can be downloaded at http://forexneurotrader.com/AD3_MOD_FNT

You can also use the script to download and set permission at the miner here:
http://forexneurotrader.com/AD3_MOD_FNT.sh

login (Putty) to the miner and type:

curl -o AD3_MOD_FNT.sh http://forexneurotrader.com/AD3_MOD_FNT.sh

and then set permission for the scipt 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.

If you have any questions, just ask. Maybe I can help.

Bye, FNT

PS: I'm going to release the source, few days. (no time yet) -> https://github.com/ForexNeuroTrader/A3_D3
