Topic: Bitmain L3+ Voltage Control Tool...Free :) - page 7. (Read 14073 times)

Just thought I'd let people know, I ran the tool on my L3++ and the default voltage appears to be 0x60 instead of 0x80 like on the L3+.

so the L3 ++ uses less power at the same hash rate as the L3+ ? . i might buy one more in about two weeks i have a 200 $ coupon some one gave me . sense I looked at the L3 ++ it says you can only use a 220 coupon or lower and mine expires on June 1 st.


What is the actual hash rate on the L3++ the website said 580Mhs but no mention of power draw?

Hey I got it, thanks guys, running 555Mhs at freq 425 and pulling 810 watts at socket measured with
my watt-o-meter since voltage mod. The original power draw at stock voltage was 895 watts.

I used the WinSCP and the two panel interface, connected with user - root and password - admin
then found the "set voltage" file in the left panel (computer) then dragged it to the right panel (miner)
into the Config directory. If you only see Root in the right panel then make sure to go to top pull down
box above  "Downloads" and click to get / and the Config directory should be in the right panels
list of directories.

I used Bitwise SSH to connect again with user - root and password - admin and the changed from the
main directory to the Config directory with cd /config. Then typed chmod a+x set voltage and then
adjusted for each board to C0 with command ./set_voltage 1 C0
All my boards came with the voltage set to 0X80.

Right now looks like 10% increase in Mhs and 10% decrease in power draw at these voltage settings.

Do you restart your miner after the mods? and also I only see a few HW errors 2-4 in the last 30 plus
minutes (one board has none), so does them mean voltage can be reduced a bit more to D0?

The way i do it with Winscp, I use the gui part sense I download any per compiled files to my windows box and open the miner in a Winscp GUI window then go to what ever folder on the right side i need in the GUI and only use SSH when needed for CMD commands and also make sure if you use the GUI for Winscp right click the file, to give it full access after it's on the miner so you can use the file .  you can either drag it from windows or send it over from left to right in the GUI an can set it up to give full access as it's dragged from the windows box .

only time i really use SSH is with some command lines or compiling, some stuff you have to compile in Linux or it won't work by dragging it over . or doing updates that can only be done using SSH.

I do it something like this once I'm logged into SSH for the miner

use SCP for the file protocol set it to port 22, host is the antminers ip . user is root pw is admin if you right click the login on the left side it gives you the option to use SSH .. in the GUI it looks like two computers just above the new session button on the left middle section for SSH using the Winscp gui ..

cd /config

./set_voltage 1 c0
./set_voltage 2 d0
./set_voltage 3 d0
./set_voltage 4 b0


I would make a video how to but I suck at making videos.

on a windows PC use Winscp https://winscp.net/eng/download.php and use SSH https://www.ssh.com/ssh/ you need both unless your willing to try the New SSH  in window 10 April update .

GUI version will be nice but if  it works just as good using CMD why not . an there is all most no chance of breaking a controller like a full firmware up date might do . some one also told me you can use this to edit the firmware i couldn't figure how to

I know it probable the same thing jstefanop is using .

Ok, so can SSH into the miner no problem and see root dir but had a issue sending the file over using WinSCP.
Do I use the command line option in WinSCP to copy the file over?
The voltage file is in my download directory so used:  scp c:/users/home computer/downloads/set_voltage [email protected]:/config
I got an error so something in line might be wrong?


I am also on windows.  I used Putty SCP and had trouble at first as well.  I resolved my issues by forcing scp (vs sftp) using the -scp flag.  By default it was trying to use sftp and would give me an error.  Maybe something similar on WinScp?

Then Donate now and jstefanop will, he did with the Alchemist miner and charged a one time fee .. it was reason able and this should be even lower because all he has to do is write the code . i wonder what he can get out of these miners this far down the road hash wise .

IN fact i donated the other day when i saw jstefanopis writing something for the L3's i know hell do it right . ......

I just donated 0.003 btc to his address

I also purchased 8 of his usb sticks last winter.



Thanks to the very few of you that have donated. Id spend some time to write a GUI version, except I would need to create a custom firmware version from scratch, since there is no way to edit the web GUI without updating the whole bitmain firmware. Figured this way would be easier and not require you to update the firmware at all.

 I know the command line seems scary to some but this is super easy to do, and there is very little risk of screwing up your antminer, even if you accidentally delete the whole root directory :p Bitmain's firmware is pretty good in that regard since they unpack the whole kernel and stock filesystem on each reboot.


It was easy on terminal via mac  I just was fooled about password because I have not done it since 2014 with s-1's.

first down load  your file


https://github.com/jstefanop/bitmain-tools/releases/download/v.1/set_voltage.zip

then open terminal on a mac  when is asks for password type in admin

Would love a version of this in graphical form. Im a noob with this command line stuff. Incidentally I have a no devfee D3 bios where you can reduce noise and watts if anyone wants it.

Agreed.  I liked Blissz's version better.  Yes, it has a fee and I understand the controversy there but it's as easy to use as the stock browser interface.

Many say that blissz is committing a crime or a civil tort.  So if you use his software you could be involved in a punitive lawsuit.

While you may like it why not pay some coin to this person to get a legal GUI


NOT sure if this applies and is completely OPEN SOURCE and NO $$$ are involved...just saying... I believe 2 parties can modify whatever the hell they want...if they
don't use the Bitmain software (make their own that does something similar from scratch) and want to void the warranty (in our case most L3+'s are past the 6 month date...
and again the NO profit aspect of this mod...

anyway, better minds then me know...but how I've always seen it done....or heard about such things..

I would gladly pay (donate to) jstefanop after a GUI is developed.
I find Linux coding annoying and would love a low/no-fee, community approved, user friendly alternative to BlissZ or stock.

Ive got my two L3 running now without using BlissZ clocked at 450 with the voltage set at


450
./set_voltage 1 c0
./set_voltage 2 d0
./set_voltage 3 d0
./set_voltage 4 b0

got it to about 1 hw error a hour doing that .


 I don't like using BlissZ firmware because of the fee it's annoying knowing some one is sucking off me when I would pay BlissZ a one time fee per miner for a no fee version but his greed won't let him some have all ready asked BlissZ an he ignored them .

an before anyone tiries  "the don't use it" EXCUSE,  i don't use BlissZ firmware ,I"M running stock firmware , i tried BlissZ firmware to see what all the benefit is which is not much other then you have more control over you miners .. so i stopped using it and hoped some one else would come up with some thing .

This is great news. I go test it out too. Hope there can be one for the S9.

Will make a donation after some testing. Thanks

Has anyone tested what each incremental decrease in voltage translates to? I underclocked all my L3+ to 0xf0 today and across 9 units seemed to have saved about 3-4a at 208v. Curious if anyone has tested what this correlates to on an individual unit.

How far have you tried OCing your miner?

Right now 462 (20%)

Given HW error rate is at 1.3% right now undervolting at 0xd0 I'll stop here first

It's been quite stable over the past 24 hours

I'm running at 462, underclocked at 0xd0 getting 595MH (due to HW errors) at 870W, compared to stock freq/voltage I get 830W

I have 4 running at 462M now with HW errors <0.08%.

In conclusion, a few things were done to try and keep HW errors < 0.08%

Individual boards with high HW @ 462 gets an overvolt at 0x78 or 70.

Boards with average HW gets a 1-2 step undervolt 0x88, 0x90

Good boards gets more undervolting. I have one that throws 1HW in 10 mins at 0xb0

My goal right now is to increase revenue and improve profitability - Hash at 595 gives roughly 15-20% increased revenue with an efficiency gain to 0.68MH/W over 0.60MH/W hence improving profitability.
