I dont think there is a new L3+ and there probably wont be any new ones. There is no incentive to spend so much to develop new miners when the price have gone down so much. The risk wont payoff and will probably lead to losses. It is probably the same with the S9.
Don’t forget chip dev times lag by at least 6mo to 1yr. Just because prices don’t make sense now does not mean they weren’t spending millions for R&D when they were selling L3s by the thousands. Bitmain was certainly working on 16nm for scrypt after they shipped the L3’s. I’m already working with a 22nm 1w/mh chip. |

I would like to point out that just because those integrated switches are rated for the current, does not mean that they would be happy operating there with their thermal design. As well, the inductor value might not be optimal for the higher current operation. As well the output capacitance might not be suitable for the higher ripple currents (especially a concern since the bulks look like tantalum)
I would say if you can populate it to add the two other phases you'd be better off than redesigning the 4 phase design for higher current. But that's just my WAG.
From the intersil datasheet:
"• Intuitive configuration using the PowerNavigator GUI
- NVM to store up to eight configurations "
Maybe they stored a config for 6+2 phase and you could just add the parts and go?
Yes I design miners for a living  Everything on here is way over specced...even at 45 amps I'm pushing though them now they are running a cool 70c without heatsinks. I have already dumped the config and modified it for 6 phases  |

What voltage setting did you use for 20ks? 900mv |

Mass exodus on the network right now...lost over 50 TERAHASHES since the beginning of june. Looks like were going to have a 10-20% lower difficulty which will be enough to bring some people back.

Screw Bitmain...this is how you get a 2 in 1 miner by yourself  Might have some fun stuff for you guys soon (I figured out the voltage controller which is how I hit 800mhz stable btw).  Are you using a voltage app to adjust please educate! Unfortunately no, trying to build a solution similar to my L3+ voltage app, but currently I had to hack into the voltage controller and control it externally via a Raspberry pi. This is what it looks like, and doubt most people will want to do this to their brand new units:  Seems like bitmain saw what I was doing with their L3's and they shut off the user space i2c interface which controls all this stuff, they also haven't release the firmware so I can't hack that to enable it. Either way even if I can get it working with the internal controller, you will still have to pull your boards and shunt two resistor pads to connect the voltage controller i2c lines, they also purposely set these lines disconnected so there is no possibility for normal users to change anything. All this makes sense when you look at the hardware, they are running these way below half power of what they can output...so they REALLY don't want people to know this. These things are polaris sized dies ~200mm^2. Each of these dies can easily do 100 watts each with proper cooling (vs the stock 20 watts). This is definitely the most advanced ASIC bitmain has made, and you can see all the billions they are making is going into serious R&D.  Even their voltage controllers are in the "GPU" territory now. This is run by an advanced muti-phase regulator. This particular board has 6 phases, with only 4 phases used. Each phase has a 60amp capability, so total output of 240 amps. Stock voltage is set at 800mv so were talking 200 watts PER BOARD, with only 80 watts utilized. Im already order parts for the rest of the phases since I'm already running near the max with 20 KSols/s I'm running now. That will bump things up to over 300 watts and over 25KSols/s. These chips will definitely be running at 2KSols each in their big miner.  |

Hello,
Is this an intro-to-mining device or can you still earn something with it and enough to reach ROI after a while?
It's to be used with low power raspberry pi 3 which I got for the pod miner that went out of production.
and how many do you need? the more the better I know but I can't afford many at once.
3MH/s seems like a lot compared to my quad core pc that does 130H/s on monero.
it's a different algo I know but I saw somewhere that the speeds are about equal to scrypt mining.
It’s more of an intro to mining than making lots of cash. There is almost no profit in scrypt at all right now with the price where it is, but your still earning the same number of Litecoins, so if prices recover you’d still make a profit. |

I read some of the comments on the reddit link, but still, i'm not sure if these specs are good news or not for GPU mining.
From what little I understand, the 1080ti we see on the market today already have 11 GB memory. So isn't 12 GB memory not much of an advantage / enhancement to existing models? Please correct me if i'm wrong, maybe the fact that it is "GDDR6" could also play a dramatic role in improving it's performance.
Compared to 580's/1070's this chip arrangement will have nearly 700GB/s of bandwidth, so for memory intensive algorithms were talking theoretical increase of ~2.5-3x, and about a 2x increase from 1080. Probably looking at 75MH/s + eth hashrate at under 200 watts. FYI this is in line with what the Titan V does (80 MH/s) with the same bandwidth. |

So, after 1 year of mining with L3+, have to switch it off.  Minus profit with it now. Better to buy LTC than mine it. Hash rate and difficulty is still on top - strange.  Are you still mining? Do you have a free electricity? Break-even for a stock L3+ on electricity alone is currently 10cent USD/kw, most large mines that account for 75%+ of the network operate way under that (.04-.07). So still have a bit to go before the big boys shut down. Most US residential miners should be shutting down now and just buying LTC with what they would have spent on power bill though( you can already see that happening with the last 3 diff drops). |

But I want to try and mine another coin/token-maybe Digibyte or another Scrypt one in hash-to-coins.
Many Antminer L3+ were sold in the last few months, so I saw difficulty almost double. You can try multipool.us if you want to try a multi coin pool that will switch automatically for you. Even if you have 6 MLDs, I don't think you'll recoup your investment ever, especially with cost of electricity. Do it for fun and leave it at that. Never say that in crypto world People that bought my original Moonlander in 2015 when LTC was $2 weren’t making anything either in terms of dollars, but would have mined nearly 2 LTC total from 2015-2017, which even at $70 LTC price would have more than 4x the intial $40 cost. |

Hello everyone
I mine with my raspberry pi 3b + and 2 asic usb gekko 2pac or moonlander 2 powered by a usb hub
The gekko with CGminer and the moonlander with bfg miner.
it works pretty well with 1 key connected, but not when I have 2 on the hub ...
I would like to run the 2 miners at once but this causes:
cg mine mine correctly with the gekko but throws me usb init failed (du moonlander)
bfg miner hasrate hut quickly to get to 0 ...
Is it feasible to throw both minors at once without problems?
My problem is he has to manage who seeks to activate the moonlander? (how to disable the moonlander?) (or mine in dual?)
below my bat:
cd / home / pi / git / vthoang / cgminer
sudo ./cgminer -o stratum + tcp: // pool. -u -gekko-2pac-freq 100
./bfgminer --scrypt -o stratum + tcp: // pool -u -p 1, d = 128 -S / dev / USB0 --set MLD: clock = 600
Thank you for your answers
I think gekkoscience cgminer does some non-nice things on the uart ports when it’s scanning/setting up the miners, which corrupts the Moonlanders, so they currently don’t play nice together. I’ll see if I can talk with the dev and sort it out. |

I just want to say, that this is the very first thing I've ever bought in terms of mining hardware. And once I figured out that my AV was eating the mining software I was trying to use, and I found a good pool (no plugs hehe) j/k litecoinpool.org and got everything setup, I sometimes like to really high and watch my two moonlanders red lights dancing in the dark. sometimes I even imagine it's a little tiny battle happening under my laptop and I wonder who's winning. Anywho, getting a little high there for a second watching the lights dancing and typing  but seriously though, I really am enjoying watching the red lights knowing each flash means I'm making money. Thanks! Some people have done interesting things with those LEDs...including making a crypto Christmas tree out of them |

You need to reinstall the USB - UART Drivers as it seems as though they were lost/corrupted, etc.. Lay of the dope and you would have known that. lol Yea, just windows updates breaking stuff as usual, silicon labs has posted new drivers that resolve the issue. |

The focus here should be on the opportunity and what reasonably priced, high end FPGAs combined with the current crypto ecosystem can do for this community. Instead we have arguments over false statements and attacks on us personally because we do business differently (and perhaps more transparently?) than others here.
Yes, as long as you are completely transparent about it, especially when large orders of these placed by farms can have and have had the same effect as ASICs on the real GPU mining community. I dont see anyone mentioning anything about the fact that these will most certainly not come anywhere near the profitability you have been advertising once they start shipping. Thats my one pet peeve of ASIC manufactures and projects like these...why are you telling newbs that have no idea what is going on what the profitability is on them on April 30th?? Or Bitmain releasing a new miner without at the very least saying how many units are in the first batch. People dont understand difficulty, and if you want to help out the community, that should be the main disclaimer at the top of the page for any new project that will add a very substantial hash-rate to current networks. |

Difficulty has been dropping lately. Maybe due to GameCredits being more profitable to mine at the moment or Bitmain turning off some of their machines in attempt to keep the L3+ appear profitable so they can dump their remaining stock.
lol highly doubt that...more like thousands of people paying more than 10 cents electricity turning off their machines. I'm sure a lot of folks have been turning off their older generation miners over the last couple months - even at 3 cent electric the A2/Titan/Alcheminer generation is no longer profitable. L3/A4/L21 generation is still profitable, if you don't have "high for mining" electric rates, but are starting to get a bit marginal. "Old gen" gear accounted for 3 Terahashes of the network though, before Bitmain started flooding with miners. Thats currently less than 1% of the network, so whoever turned those off no one even felt it. Recent drop is definitely from this gen gear...which looks like its already last gen since its obvious that new gear is already hitting the network (I am already playing with new chips FYI). That is great news! I hope the new chips have a reduction in power of 50% with increases in hashing power of over 100%. jstefanop a pod miner like the old Gridseed units would be killer to start, the USB sticks draw too much power to be run though a hub at higher hash rates over spec. Unfortunately those days are over. ASICs have caught up with node development at this point so it was not like the fun days of goin from 90->40->28nm. What I can say is the chip itself does under 1W/MH, and im pretty sure I can get pretty close to that with my design. And yes my new miner will be a pod Hopefully ill have something concrete to announce in the coming weeks. |

btw, you obviously have intimate knowledge of xilinx, fpga, and have been on the forum as long as I have.... Where did you say you were from again? I think I can taste a little salt in the air.
How is poking at your business dealings/model him being salty? Few of the higher profile members having this discussion here have been here for long enough to know how most of these pre-orders end up. Its more concerning to me that more of these discussions are not happening. I would not touch this with a 10 foot pole if it was not for that fact that is seems like your using xilinx's supply chain/board partner and design to product these, so it at least takes a good portion of the failure risk out of the equation. Still your collecting a huge sum of money...since they are so un-trusting of the market as you put it, what happens if they get spooked next month and decide not to go through with the deal? |

I have 7 ML2s OC'd @ 900mHz on 2 hubs (2 on pluggable 7 port / 5 on a no name 13 port hub) via raspberry pi. They average 35-36MH/s total. The temps are in the mid 50sC. They are all separate workers on separate instances of bfgminer. The USB ports stay consistent after reboot - haven't had to reboot the pi since this final setup was implemented a month ago. When one of the MLs goes offline, I receive an email which then send a text message, then use TeamViewer to log into the pi via iPhone or PC to restart that instance of bfgminer. I used a voltmeter to tune the first two, but now just use those base pot positions on new ones, then tune them on the fly while watching them hash. Once the error rate goes below 1% I'm good. Usually 15 minutes to tune. Some have gone two weeks without restart. I only have to restart the bfgminer instance for that specific miner. Not the raspberry pi, not the hubs. I haven't had to reseat the miners in the physical USB ports yet. These are reliable and jstefanop has very good support - hence the reason I'm taking the time to write this. Maybe the raspberry pi makes them more reliable vs windows? Maybe it's the USB hubs? Not sure, but 7 out of 7 all @ 900Mhz @ over 5mH/s each with no issues is pretty good. For cooling, I have a 4" case fan blowing across them. I've bought them from futurebit as well as ebay and have a wide range of serial numbers, meaning quality over time is consistent. In the linked image, you'll see the seven instances and hash rate. These are not going to make you instant rich, but who knows what the bits of mined coins over time may be worth in 10 years. These are fun if you like to tinker with technology. Reading this over, it looks like a paid testimonial! It's not haha.  (you'll notice they've only been running a day due to router firmware update breaking the internet connection) Thanks for taking the time to write this! Obviously this is the support thread so your only going to hear about people having issues, and not the thousands of people running these 24/7 with no hiccups...so awesome to hear from you once in a while! |

Interesting that the answer to my question seems to be don't mess with these things and they don't work reliably. i am running these on 2 separate powered usb hubs and they work just fine and have been very stable. it seems like the problems start when cranking them up too high and when using inadequately powered hubs. I don't have that problem. I do understand the response that running them with separate workers/devices does not really accomplish anything and isn't worth the bother. Thanks.
All this stuff has been covered dozens of times in this thread, and your specific question is covered in the FAQ on the first page. https://bitcointalk.org/index.php?topic=2420357.msg24766878#msg24766878 |
