Bitcoin mining is now a specialized and very risky industry, just like gold mining. Amateur miners are unlikely to make much money, and may even lose money. Bitcoin is much more than just mining, though!

I used the software that @jstefanop has put out here on 2 L3+ units last night! Excellent! I used the WinSCP to do it all - I have Putty on my system, so not sure if it picked up on that or if it has it embedded in the software or install, but once I established a connection to the miner with WinSCP, I was able to open a Putty window from a button in WinSCP that opened right to the miner already connected to - just entered password and followed the directions. Anyway - I will write more on it later but the end result was that I got them both running at the lowest power (0xfe) and was able to clock them both up to 394MHz (~515MH) without any issue. I recorded temps at each step and after clocking up to 394, the temps were back to about the same as they were running at 0x80 (normal voltage factory setting). So I ended up at about 15% less power use with about a 2% increase in hash rate with temps staying in the same ballpark as they started at. I was getting no more HW errors that before with this config - I was targeting lowering power use, then improving hash rate - while maintaining similar temps. I'm sure I could have increased hash rates by more than 2%, but I didn't want the additional heat. My miners are running overall hotter right now than I want - getting ready to move them to a cooler place with better airflow, but until then, I need to keep the temps in check. Very Good! Now - I have two L3++ units as well. They are running at 450MHz from Bitmain and running generally in the 590-600MH range. So my question on these - is there already any kind of automatic voltage adjustments going on with these L3++ units? Their MH number seem to be fluctuating much more and much more constantly - like something is being adjusted constantly. My L3+ units stay around 502MH to 503MH very consistently (well, now 514MH to 517MH  ) - but these L3++ units are bouncing around probably 570MH to 615MH constantly. I mean I just site there watching to numbers fluctuating none stop (using Awesome Miner). So I just wanted to see what you guys think - I know I saw someone else had used this on the L3++, but just wondering if it might interfere with Bitmain's settings if they may be messing with an auto voltage system design as well. Also, one of my L3++ units has 1 hash board that is running a little more than, but pretty close to, 1 HW per minute with factory settings. Is this worth contacting Bitmain over? I'm wondering if dropping the voltage on this unit with this software from @jstefanop will potentially ease that number down - less power - less heat - maybe help improve the HW rate? And lastly - I had a thought/concern about the lower power settings. When running electrical - it is always better to use heavier wire as it is more efficient at carrying the electricity: less power loss due to resistance (generally lost in the form of heat) and improves the watts used by the connected equipment, etc... When doing electrical runs that are too long for the gauge wire used, you frequently hear about how that can damage equipment due to the power reaching the connected devices not being strong enough - too much lost in the transmission and the overly low power somehow causing damage to the connected devices. Is this is a concern here? If we lower the voltage down to lowest setting - is this somehow stressing the miner's components in a way that might cause them to fail earlier? Should we look at lowering the voltage some, but not to the lowest settings? I don't know and am truly asking. What are your thoughts on this? I am very happy with the idea of lowering heat, power costs, and/or even getting improved hash rates - but... Thanks! Play with your settings. I was gettin 620 out of my L3+ for months stably with decent temps. |

Thx jstefanop.
Testing my ten L3+ with lowest voltage (0xfe). Currently running 400 frequency.
Can this set frequency for each board individually?
for example :
board 1,2,3 running very smooth on 450 frequency & voltage 0xc0 with less HW
board 4 cant go over 400 no mater how high is voltage (0x30) , too much HW (error every sec)
I will chime in it can give multiple voltage for each board. Not mutilple freq. So this means you can choose freq 400 knowing the three boards are under tasked or choose say 425 and tossing lots of errors on the poor board btw don't volt the bad board that high you will just burn it out. personally i would swap it to a different L3+ but if you have 1 l3+ that is not an option. I have an L3++ I'm working on refining now. Chains 1 and 3 had voltage set at 0x60 by Bitmain. Chains 2 and 4 had their voltages set at 0x3f. Frequency is at 450MHz. These were all Bitmain settings. Chain 4 has been getting excessive errors - as high as 1.48 HW errors per minute since I really started tracking it today, where the other chains are 0 or very few HW errors (including chain2 that was also at 0x3f). I raised the voltage on Chain 4 to 0x30 and then to 0x28 as it got better at 0x30 and then even better at 0x28. It is now under 1 HW error per minute. But I saw your comment here about not setting the voltage to 0x30 without burning it out. Bitmain has this set to 0x3f by default. Would you recommend leaving the 0x28 setting being that it showed improvement in HW errors - or drop the frequency some as well as lowering the voltage? If lowering, what would you recommend as the max higher end voltage setting? Thanks! |

/Users/macmini/Downloads/set_voltage so I think that is the directory above so I tried this scp /Users/macmini/Downloads/set_voltage root@192.168.0.109:/config and this came up root@192.168.0.109's password: I could not enter a password and if I hit enter it said wrong password Have you tried typing in your password and pressing the enter key? scp and other ssh tools will not echo a "*" or "." when you key in the password (so people cannot guess your password's length) ... UPDATES - Running my L3+ at 462M (20% OC) All boards are set at 0xd0 Error rate is the wrong side of 1% right now Effective hash rate at pool has been good - averaging 550-600 Power draw at wall ~ 870 W compared to ~ 830 W at stock voltage and speed I'm now getting 15-20% more effective hash rate with only a 5% increase in power draw. @Nazzer (and others as well) - what are your targets for HW errors? For nonce HW Error %, but also, number of HW errors per minute for any particular hash board. I see that @philipma1957 says he tries to keep under 0.05% nonce HW error%. I think you are saying in this post you target 1%? I have seen references to keeping under 1 HW error per minute, but not sure if this is per board or total HW errors per minute across all boards. I would think it important to know per board so I/we don't push any individual board too hard on HW errors. I have thus far been trying to keep each board at less than 1 HW error per minute with Nonce HW Err % to 0.05% or less. Also, I saw in the L3 thread, that in early 2018 - there was a change in L3+ has boards - type N and type S and that one or the other cannot be OCed as high as the other. Do you know how we can tell which hash boards we have and what max ranges of OCing can be accomplished on each? Thanks! BTW, I have tweaked 2 - L3+'s and 1 - L3++ (voltage and OCing) and have improved hash rate with lower watts - currently have dropped wattage use across the 3 by about 330watts! I have one more L3++ to tweak and may be getting another L3+ soon. Once I tweak the last L3++ and figure out my overall savings, I will contribute some BTC to @jstefanop for this cool software! |

Yep, well said philipma! I have used it on about 20 L3+ so far. That might go up based on reliability of the modded units. The big benefit for me is not the $ saving on electricity or any boost in hashrate. It reduces my overall temps and pulls my electrical current consumption back to safer levels. The drop in temps is very dramatic, 3-4 degrees C per board. I was planning to monitor my machines for a while more before donating, but it's worth .25 LTC and more to me, so here's my first transfer. There will be more if I'm still happy in a month or so. https://live.blockcypher.com/ltc/tx/ab4d415f25773ceca707831a8600528366078fca2fba5fb5ccfb454eb393ad27/ |

how do I read the chain voltage?
I tried :
root@antMiner:/config# ./get_voltage
but its says not found... FYI, I can apply voltage successfully..
I thought of reading it before applying changes...

Agreed. Windows users just need winscp to move the file "set_voltage" from their PC download directory to their L3+ /config directory. Drag and drop the file over from your PC to the L3+ Then use SSH or PuTTY to run the few commands listed on page 1. Not difficult. |

I will donate as soon as me and my partner get around to making these tweaks...but as of now my partner is still setting up L3+'s in the box and dealing with an electrican...with his stuff..if this keeps up ..the whole thing will be 'moot' anyway...my L3+'s that are up are making 53c a day after electric....just saying..others may be in despair and not really also be jumping on this mod...as we speak..for the same reasons as me ....why bother improving the engines on the Titanic if the iceberg of difficulty is gonna sink the L3+ boat anyway... IF we manage to get the LTC price say above $160 again, (where I'm making more than a $1 a day) you may have some more motivated people...as to myself ..I watch this mess and basically am turning into a 'lump' of an unmotivated miner....ie (are the miners up ...good....goes back to bed pulls covers over his head) |

If your scraping by and can reduce power by 10-20% thats pretty big...of course 10-20% power reduction did not matter when the L3's were making 1k per month last year |

If I had access to my miners at my hosting location I would certainly give this a shot... And I would gladly donate to this effort. So I am stuck paying through the nose for power I shouldn't have to consume.  What is the average power savings so far with this mod? I fired off an email to my support at my hosting location to ask them if they would be willing to perform this mod. |

If your scraping by and can reduce power by 10-20% thats pretty big...of course 10-20% power reduction did not matter when the L3's were making 1k per month last year I probably was not clear...if the price of LTC say reaches a point, where you can't mine it with the elec costs for the majority of the 'consumer' small guys 1-20 Bitmain units say...then that leaves Bitmain......centralized mining....likely with new 'supposed' 1.5gh units they will mine for 5 months over the summer and allow us 'crumbs' of pre-orders in the fall ...after driving up difficulty another 30% say...thus, the choice is see all your pow-scrypt current miners scrap'd and watch bitmain play these games and have to 'start over' with their products on their timeline in say late fall... so my point to the 'voltage' fix...sure...it helps a lot....say you get 15% reduction in power..sure...it helps...but just saying...looks a bit rigged...Bitmain...coupons expireiing (most) june 1st, I think it is, etc, etc and may not really matter much in the next month if trends continue..the end result is pow scrypt pretty much centralized to bitmain data halls and the rest of the stuff doorstops ..remember we are looking at 30% difficulty rise per month....we saw this game by KNC in 2014 using pre-order money to make BTC Neptunes for their data halls first and then release to thenpublic...they were good for 5 months and made 25% of cost back at best.....not exactly the same thing...but the intent to control pow-scrypt seems to ben the same...as KNC BTC tricks ..back in the day... I will get this stuff up eventually, electrician issues on the place I'm hosting and they have to get 160 L3+'s up (bigger folk than me) thus probably be 2 weeks before a guy can get to these mods on my stuff anyway, we will be the first to know I guess I'll get the donation out as soon as 1) installed 2) and see what I'm making to give him appropriate $$$ he deserves... but a couple months more of sideways in price with difficulty rises and especially if bitmain really does have supposed 1.5gh units for pow scrypt coming out this summer and same pre-orders for fall that has me a bit concerned...hopefully I'm dead wrong in a big way... later brad |

Hey all, I took the work that jstephanop did for the L3, cleaned it up a bit to make it easier to script with (there is a quiet mode which just outputs values). I then added support for the A3 based on the work that FNT did. We now have a single program that will work with both the L3 and A3 (don't have a D3 but it may work on that too). At this point I would call it pre-release since although I have tested it on my L3's and A3's, it has not had a lot of testing. Some of the changes I made include timing changes in theory to make it faster, so I would be interested if you are seeing any error messages at all. Like any of this stuff, use at your own risk.  Code and binary are here: https://github.com/darval/bitmain-tools@jstephanop @FNT If you guys want to merge all this into a single repo, I am good with that. Take a look at the changes I made and see if you see any issues, or are interested in merging it back into your versions. |
