Yeah, just tried it on 300 and the hashrate is half so no point really.
Power draw on mine at 300 is only 500W
Power draw on mine at 300 is only 500W
That's not bad at all but at what hashrate?
I'm down to 1kw per miner 825MH and about 75c which works quite well.
What voltage have you set yours too?

What voltage have you set yours too?
what is your result? how much less power do you use now? I drive with 300hz and need 670 W this is ideal because I have solar power brings me 4.6 SC and only 50 degrees heat
Nevermind, managed to figure it out 
Hi All,
I was wondering if some one could assist me with under volting, I've installed the script and all is working fine, I am just unsure of the HEX values.
root@antMiner:/config# ./AD3_MOD_FNT 3 b9
Reading voltage
chain 3: voltage = 0xb8
Setting voltage on chain 3
Voltage OK!
Reading voltage
chain 3: voltage = 0xb9
Success: Voltage updated!
If you save money, check it and maybe then donate something.
root@antMiner:/config# ./AD3_MOD_FNT
Reading all voltages
chain 1: voltage = 0xb9
chain 2: voltage = 0xb9
chain 3: voltage = 0xb9
That's what I've done so far but it's made no difference at all, how do I go further?
Thanks

Hi there,
I would like to test it mornings but like to ask - any results for hashrate, errors and power consumption for A3 and D3?
Ill sure test it but asking prior my tests not to try find what is already found...
EDIT: ok, nobody answered
My results with A3 - power draw decrease around 150W with different board settings between fe - fa
My results with D3 - going to find and test some now...

i have 2 A3 run normally , i turn to 1370 at 1480 watt, no use this script.
hello,
i have an question if i may.. i woud like to understand how the hex value works...
http://hextodecimal.com/index.php
i can see hex 00 means in decimal 0 too, the end is FE and has decimal value 254, so it means i can try all 254 values? so 10V is minimum and 12V maximum..chngind hex values means i can cut that 2V (10V-12V) into 254 small pieces between? sorry if it sounds stupid, i dont know how it works, trying to udnderstand and do not want to broke something as i have 2x A3...
B8 has decimal value 184 and it is default from bitmain, so its how much voltage?
and second part of question..i will remain frequency as is only will play with the hex value of voltage to lowest possible without HW errors,right? i assume some chains will be able less V and some not, but thats fine.
so thank you again if you reply

Will this only work with A3 and D3?
Does setting the voltage too low stave the ASIC?
I had to set this back to the default clock to get it to work, If I over clock again will I break anything?

I'm curious of the same thing - I have undervalued (0xfe) and overclocked (612) - curious of the effects and energy usage. Sadly I don't have a wattmeter other than what the power company is telling me; which doesn't help when it's summer time and A/C usage is already higher than usual. I am curious however if anyone else has undervolted + overclocked and what their experience was - hashrate/power consumption/stability - etc. My unit has ran significantly cooler on the undervolt setting. It's outside in window well because of the noise. Outside temps reach ~100 F some days. PCB usually peaks at 76 C.

My A3 is under volted to chain1 0xf8 chain2 0xf8 chain 3 0xc8, freq @ 312mhz for now, fans at 50%, 432gh/s avg, unknown power consumption but it runs stable and is a little bit cooler now.
Could you all please share the settings you are using and the Frequency and Power.
It would be much appreciated.
It would be much appreciated.
A similar program for S9?
Hi patchy,
With the program you set the voltage setting/regulation of the PIC for each PIC on each hashboard.
This setting is fixed, also after a reboot, etc... the values you set via program are stored in the PIC(s)!
If you want to change this, you need to run the program again and set the hex values e.g. to default.
You won't see the settings in any config pages / files, etc.. you only see changes either via program -> readout,
and indirectly if you use a wattometer for power consumtion and/or temp. of chips.
About costs/power/hashrate saving/optimization -> if you use high hex values you save energy,
if you use low values you're getting better hashrate but use more energy.
You need to test which hex values, hashrate, chip temp. and hardware error relation is best for you. If you got a good one or can report the power usage maybe you want to tell.
I use highest hex values, because I want a low chip temp and low fan speed.
Bye, FNT

Hey team. Thanks for the sweet script FNT. A quick question about this - If I unplug power, and plug it back in, do the voltage settings remained unchanged? If I reboot the device from the Antminer config page, does it retain the custom voltage settings in that case also? Sorry, I did not see this question asked/answered already; I'll blame poor eyesight.
Thanks again for the help. Any suggestions on a good place to better understand voltage settings in hex for the ant miners? Curious what you all picked to save the most energy while maintaining an average hashrate of 815GH/s or above.

hi there, did it work on D3?
D3 : 
- It's all right. It is necessary to test one board each. All at once does not want.
A3 - successfully.

problems with d3. The first time the program saw PIC, put out the voltage. Next did not detect the version of PIC.
This seems to be an read error of i2c. Just read (exec. the program again) should be working...

If you can release a new a3 firmware with these voltage settings id happily pay 1.5% dev fees.
link?
My A3s have been running for almost a whole day and still trouble free.
The main benefits for me is the noise reduction.
btw, f8 may be too aggressive and the HW is about 17000 for 24 hours.
but I would keep the setting since I still got a good hashrate at siamining.com.

hmm very interested in what the power reduction will be.. anyone?
It worked very well on my A3s. I set the voltage to f8 on all chains.
Thank you very much Sir.
Thank you very much Sir.
what is the power save ?
I don't have a power meter so I couldn't tell.
But I noticed that the temperature on the chips went down by about 3-5 C on average.
and the fan speed is slowing down as well, noise level reduced accordingly.
Now the environment temp is about 29C, and the chip temp ranges from 74C - 84C and the fan speed ranges from 5300 - 5600.
I am using the factory freq setting 600M and I got the avg hashrate of ~830M
It worked very well on my A3s. I set the voltage to f8 on all chains.

Hi!
ohh, ok, this sounds like this error? -> omap_i2c 4819c000.i2c: controller timed out

i think is when you are testing the voltage reduction and you keep sending new commands to the program, then it freeze

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.

yes, it can sometimes happen, that you get an read error on the I2C bus, and the you get an error message.

tried it on A3 - Got message ...

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.

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