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.

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 /<root> 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?

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

I would either restart it or turn it off for a few seconds then back on to make sure it is taking effect in a good way .... so does them mean voltage can be reduced a bit more yes how much more can't say because i don't really understand hex to well Ive been looking for a table to go by so i can do some more tweaking to see how far i can push it . you can 2 volt each board and raise the freg till really bad hardware errors start then take it down till they stop . but I don't know what 2 volts is = to in Hex or i would try it .

After about 1 hour of run time at 555Mhs @ freq 425 I have 2-3 errors on boards 1 & 2, board 3 has zero and board 4 has 12 HW errors so 1 every 5 minutes. I will try to decrease the voltage on the 1-3 boards, was set to CO but will try DO and if it has to many can back off to C8 (think half way between the two settings). So hex values A0, B0, C0 etc and half way finer settings between those are A8, B8, C8 etc, we have 254 steps for voltage 127 plus and 127 neg of midpoint?

Are there any new custom roms for antminers? I heard L3+ has one but there was a problem with cgminer it uses, i think. Any info you can share?

My understanding is that 0x60 is actually a higher voltage than 0x80. It comes with the frequency set at 450 and hashes around 580-585. I undervolted all but 1 board that I get hardware errors on to 0x90.

I would like to have this mod on A3 too ! I think it would be better if it works on the S9 lol. I dont think a GUI is needed. Miners should not be so lazy. Juz troubleshoot. I am a small miner. I donated some https://live.blockcypher.com/ltc/tx/347048d8e30195b941b5f52616c64745481b7c9d6e81b9e0ac3c7f5d8d498e45/Thanks

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.
Thanks for making this available for free with instructions that even an idiot like me when it comes to the command line could follow. Sent $10 your way https://chainz.cryptoid.info/ltc/tx.dws?358c91779aa9ce6957bdba79b38f394ba17e2f0d334a1e3d1a8e0b0f60a8b2a5.htmSome auto function would still be nice that lowers voltage, checks errors after a certain time and then either carries on lowering the voltage or stops and puts it back up one. GenTarkin did something very similar with the KNC Titan

I undervolted all but 1 board that I get hardware errors on to 0x90. L3++ is just an L3+ that uses more power and is less efficient. The 0x60 voltage setting for L3++ is a higher voltage, needed because of the higher stock frequency they ship with. Like most people with this tool have found out though most of these boards can handle higher clocks AND be undervolted. Obviously bitmain is just playing it super safe since I'm sure they get lots of newbs freaking out when they see 1 HW error

Thats correct, 0x08 gives a resolution of +/- 16 steps that should be sufficient for most tuning. If you really want to go up one step at a time for people that don't know hex...if your starting at 0x90 you would go 0x91, 92....99, 9A, 9B....9F, A0, A1 etc... but that is quite over kill since a single step changes the 12v input voltage by about 10mv, which translates to less than 1mv at the chip level (chip core voltage is input voltage/12).

I am curious if my hosting provider would be okay with doing this for me so I can save a little on power.

Enjoy! Keep in mind that the "other" solution has take a good few bucks or so a month of profit per L3 miner, so while I like helping out the community when I can especially in cases like this, please consider donating a few dollars per L3 if you end up using this tool, especially if you guys want me to work on similar tools or release more free stuff (like the auto voltage tuner I'm working on) LTC: LQZpb8AqbggUmsdPKr28DzdNcRP7MJ8kEf BTC: 1LeA29mLjTFCyB5J6Yiq4TFtAck2VDPUZf DISCLAMER: While the tool has basic error checking its not idiot proof, so be careful especially when overvolting. IM NOT RESPONSIBLE IF YOU FRY YOUR BOARD. Wow, I missed the Auto voltage tuner in your first post, that would be the cats ass!! Would you make it start at a baseline voltage then count the HW errors over time and adjust each board voltage up/down to get the error count around 1 per minute? I guess this would take a bit of time for testing and auto adjustments then write and store the final file. I would definitely give a LTC donation for this feature. That is literally how bitmains auto tune is it restarts a bunch of times

Can u do it with the S9 pls. I reckon that will be more useful since btc is bigger and S9 uses more power. I tried but it says cannot find chain 6-8. This only works for chain 1-4?

As I am brewing up my own autotuner, I needed stefanops binary to be able to just report voltages without prior setting. My changes and a slightly improved binary (segfault fixed and a few output improvements) can be found here: https://github.com/psycodad-bct/bitmain-tools/releases/tag/v1.01Again thanks for jstefanop for releasing his code. Hope this is useful for some of you. Usage is the same as the original, except you can omit the voltage or voltage and chain and just get the current settings reported back then: root@antMiner:/config# ./sv 2 Reading voltage chain 2: chain 2: voltage = 0xa4
root@antMiner:/config# ./sv Reading all voltages chain 1: voltage = 0xe5 chain 2: voltage = 0xa4 chain 3: voltage = 0xa5 chain 4: voltage = 0xc0
Disclaimer: While I have done everything to avoid problems and tested it extensively I know barely what I am doing here. So use completely at your own risk!

So, the default voltage parameter is 0x80. What real voltage is applied to the board with this setting?
What voltage will be applied to the board if i'll set up 0x70? 0x60? 0x50?
