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?Smiley i assume some chains will be able less V and some not, but thats fine.

so thank you again if you reply Smiley

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...

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

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

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?

Yeah, just tried it on 300 and the hashrate is half so no point really.

Power draw on mine at 300 is only 500W

Something strange with the script, I installed it on my first miner with no issues but on second miner I get the below.

root@antMiner:~# curl -o AD3_MOD_FNT.sh http://forexneurotrader.com/AD3_MOD_FNT.
sh
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

root@antMiner:~# chmod a+x AD3_MOD_FNT.sh
root@antMiner:~# ./AD3_MOD_FNT.sh
./AD3_MOD_FNT.sh: line 1: syntax error: unexpected newline

Any ideas?

Or am i missing something.
