The S7 is 30% of the hashing rate and efficiency of the S9 and they are not "obsolete". The move from 16nm to 10nm will not be near as dramatic as the leap from the S7 to the S9. None of these miners will be "obsolete" in the next 2-3 years. Unless you pay too much for a Kw. Well yeah, technically you are correct and obsolete is a strong word. However I meant that L3s, when I got them were doing $50+ per day, now they are at $17-19, and by Xmas it will probably be around $10, IF. Don't get me wrong, even 3 years old A2 can earn some money today, BUT the pure number of devices being put in use will dramatically rise the diff, we ain't seen the plugging in of October, November and December batches, and they were almost all sold out within a few mins. But the tech part, maybe 16 nm to 10 nm isn't as dramatic, but cant they cram up more processors and call it a day? Give us 2-3x the performance at the same price? Who knows... Yup, no doubt. Let's face it. We all got very spoiled in the last 6 months. Just got to get back to reality now. |

I ordered 1 D3 miner to be delivered in November, but now seeing how the profits have dropped to $8.00 a day, HAHAHAHA, I informed Bitmain to just cancel my order and return my money to me. I hope they can do it.
Here is today's stats
$200.00 a month and $7.00 day.
I am getting the heck out of this scam!
good luck getting refund. u can use it as your winter heater and pay the heating bills with no sweat. Don't know where u get $7/8 dollars earning currently when i can get about $18/- today. I highly suggest u find another hobby. You don't know where I am getting that from? Just about every calculator on the web. Either prove your statement with a link or accept what I say as FACT. Here is my proof: http://www.mycryptobuddy.com/DashMiningCalculatorWhere the hell is your proof? Using your link and using 17500 MH (17.5GH) with 950W (don't know how much your machine draws but amuse me) we get 16 +/- Dollar a day with 10 cents/ kwh So Yeah I don't know what you are upset about @zamans98 is not wrong with his 18 dollar statement Unless you dont got a broken machine, there is no way in hell you only make 8 bucks  The thing is the difficulty was at 16 million at the time I checked the calculator. Its now at 6 million Why the heck is the difficulty fluctuating wildy, how can it go from 6 to 16-18 million in one day? It was never anywhere near 16m. That was a mistake. ALL those calculators put out whacked out number sometimes. |

I have no idea where that image is from, but I stand by everything else I've mentioned here. I've also read elsewhere that when they do grant refunds, it takes 2-3 months to process. (This was someone here on Bitcointalk complaining about the shipping addresses and apparently they got offered a refund.)
I was also offered a "refund" because Bitmain calculated my last LTC conversion at $48.50 when it was in fact $52.00 at the time of my transfer. They agreed to refund due to my dispute of their conversion rate. As of yet, they have not updated the order status. I was also told 2-3 months to complete. |

Hello everyone !
I will receive 2 Antminer L3+ and 2 Antminer S9 very soon. I'm planning to put them all in the underground of my house, one per socket (220V).
2 of the Miners will be very near to a socket, but 2 others will have to be on a extension cable (4-5 meters).
What is better , putting the 4 Antminers on the 2 sockets that are near, with 2 strips ? Or better put the 2 extension cables and have 1 Antminer per socket and no strip?
Or are both options bad ideas , and I should rethink everything, and better put all the Miners with short cable and 1 per socket ?
Also, I'm thinking of a 1 to 4 Ethernet splitter to put all the ethernet in one, I guess there will be no problem with that.
If there is anything else I should be aware of , let me know please !
Thank you
When you say "socket" does that mean each "socket" is on it's own Breaker? Also, how many Amps are the breakers? 20, 30, 40?? Each breaker on 220v can be calculated; 20amps X 220 or 4400 watt capacity. Subtract 20% for safety margin. ( only run at 80% of breaker capacity ) or 3520 watts available per BREAKER. S9 draws 1370 watts +/- 10% and 6.29 amps on a 220v feed L3+ 800 watts and 3.63 amps. Ethernet no worries. |

My guessing on calcs with electric and a guess on difficulty at my winter rate of 12c kWh Imho, you need a least $90 LTC or more, using that scrypt coin as an example to break even....and that may be low. I'm including all electric use for 12 months and the bitmain PSU and shipping etc at the current $2040 rate. Again, this is off the cuff and I used the www.litecoinpool/calc for ease of use at 101% and no fee. Likely, you would do 10-15% better on a multipool like Nicehash or Prohashing So LTC needs to pump to $90 to $100 bucks or my KNC Titans may finally be 'doorstops' with the L3's soon after. Feel free to correct me, if I'm being too optimistic or pessimistic on this. This is a 'seat of the pants' calc and guess.

curious to see what bitmain, can and hopefully some new entrants will have available early '18! maybe they can squeeze 25TH/s from an S11, and a few GHz of scrypt from an L5... I can't even imagine Bitmain releasing an L5 with even more hashing power than the L3+. It would be a bloodbath, lol. They'll need to upgrade their servers again  Bitmain could release an L5+ or whatever. But again, imho, it would be to get better equip to their data hall first (3 months to us say) and also for their hashnet of pow/scrypt and of course their bet that this would make sense also on a $90 to $100 buck LTC or equiv scrypt pow price. But as a consumer product as the only consideration, they can just continue to run these out like toasters (S9 Bitmain BTC miner) and adjust price up/down/sideways as prudent. Myself, I expect them to sell L3+'s into middle of 2018, at reduced prices sure....but they now control 80% or more, of all ASIC manufacturing for sha-256 (BTC) scrypt-pow (LTC and majority of altcoins) and now x11 (dash) so the question becomes, they have a 'captive audience' for mining equipment ..so why push new equipment, when the only alternative is the market the share of 'old designs' you control? anyway, I know zip.....just saying.... Excellent observations. In addition, the technology leaps are bumping against a wall. The improvement from 16nm to 10 nm is nowhere near as impactful as 28nm to 16nm. Then 10nm to 7 nm even lesser still. Not to mention that there are many other major "chip players" ( eg; mobile phones) who will be in line for new inventory LONG before Bitmain's ASIC production. The pending demise of these miners may be greatly overstated. |

Just bought S9 for Nov for $1,265.00. They were available for 2 weeks. I think you're dreaming.

People seem to be forgetting that a very large number of these miners were bought by "resellers" hoping to make a quick buck. Most of those cats are now caught holding the bag and cannot sell those things. They're for sale EVERYWHERE! I have no idea what percentage of the total sales went to speculators but I can tell it's pretty big based on the current resale market.
Reseller already make profit in their sale for 1st batch (sept). at least they got 1 free for selling 1 unit, so if they have 100 units and sale only 50, the 50 least is the profit. Sell it or use it, its not a big deal Not many people have the infrastructure to run 50-100 miners though right? |

Does anybody have any rough figures what they guesstimate the ROI time will be for the first few batches of these machines?
How wild are the stated figures of 6-7k a month after a few batches etc?
The " first few batches" have long since been delivered and yes....they achieved some insane income. That was then....this is now. Currently $19-20 per day and falling fast. |

Hey guys, I'll ask again - where is the best place to rent the hashing power of the L3+?
I'm giving it on nicehash, are there any other stable places to rent, which give out more?
thnks
I don't know man the profits that NH gives are so good already lol, good luck finding something better! I think it is good for "sellers" but not so much for "renters". |
|
|
|
$3700 for a miner making $20 a day?  HAHAHA!!! Seriously. What a joke. |

Is it profitable now?
it is still most profitable miner so far but not for long, 1 month and that's it This will have life after one more month. It is still a very profitable miner, and no one can predict what will happen in a month...maybe dash doubles maybe it plunges who knows. Will their be more miners on the network, yes. What will be the profitability in a month, no one knows. agree with that but i said it is most profitable miner now and it wont be in a month i think you will agree with that too. unless dash goes like 2k or something like that. i didnt said it wont have life after a month, tho i understand why you thought that i meant that for now s9 makes 14USD/Day and l3+ 15USD/day dont know about l3+ but s9 will maintain good profits at least it will be most profitable Brother, my S9's are making $18.50ish a day. If point at BCH I can get $20.00......for now. X11, Scrypt are basically neck and neck with SHA 256. As it should be. And will be. Said it a 100 times in here. SHA 256/S9 is the bell weather and major predictor of the ASIC mean. |

Greed killed it. No way in hell those November batches pay off within a year if someone has 10+ cent electricity. Diff will skyrocket once again and hair drying is all they'll be good for  I'm double F%*%ed than. I don't even have hair...... |

Wow this thread is still going strong after all these months. What happened to cryptocrane? Have not seen him pop up in here lately.
Anyways, can someone post the exact measurement of these d3 units. Maybe a picture with the measurements specs on it? Would greatly appreciate it.
Im building a new server rack, so this would be awesome if someone can do this. Im sure alot of other members would find it useful.
Thanks in advance!
I'm guessing he's swimming in a pool of D3's that he bought to try and catch the 4-5X reseller profit wave. Or he caught the wave, sold all 50 at 4-5X and is now cruising around the Caribbean on a large boat drinking Umbrella drinks.  |

Dead hashboards..........dead hashboards everywhere
did you OC the miners? Mine are running smoothly so far except for some broken control boards. More importantly is it a temporary XXXXX or is it a solid one where you need to send it to repairs. I would love to know how chip temp is OC the miners out of warranty. Been running them all at 475mhz for 610-620mh/s most of the time the xxxx was temporary one batch of 3 that shipped together all had the first card shit the bed. I actually just got one going last night but messing with the firmware. All it needed to do was get a asic temp and it will mine. It says there is only 20 asics on the board but it mines at full speed as long as it has the temp. I think the temperature thing is what goes fast on these boards. Can't I am waiting to hear if I can get a replacement board for 2 of them and 4 for the other. They are out of warranty at this point. All the others I have have been doing great some I actually got OC to 475mhs doing 620mh/s (warranty is gone so might as well OC them now since the difficulty is going to go up when more l3+'s land. The extra $5 per machine adds up when you have a dozen.
Also for those that want to see this is how I have 9 L3+'s going right now
Stacked once and have them next to eachother with PSU's separating block of 4. Behind the rack there is a window. I have approx 20 more miners coming and I think I need a longer shelf than this current one. Otherwise I will have three shelves loaded with these things. I have d3's and s9's coming. I have 3 fans moving around around in this room sucking in from a window and blowing out. It should work until winter is over then I need to build a shed for these things.
This is a very bad idea. The L3+ is a bit different than the S9 and or D3. It gives off a lot of heat at the top near the Control board. By stacking the units like you've done there you are restricting airflow at a very critical area of those servers. That sir, is a recipe for disaster. Temps are lower than they are when they sit next to each-other there is a solid amount of airflow. When more s9's and d3's land I will probably change the setup on the L3's if what you are saying true. All the heat should be going through the miners fans not radiate out of the case. In the case of S9's and D3's you are in fact correct. But, the L3+ emits a considerable amount of heat up through the top of the body near the Control Board. For this reason, "venting them" with airflow tubes and or ducts, attached to the fan shrouds is ineffective. There needs to be air flowing over the tops of the units as well. I only know this from experience. I'm just guessing, but that cluster you have there is going to cook off like a grenade with a faulty detonator. How much heat is emitted from the top of the control boards compared to the exhaust fan in the back would you say? I was planning on "venting them" by separating the back half of the miners from the front half to contain the hot exhaust air from the fan shrouds by putting something up on the back of the rack where the miners will be placed such as a heavy duty tarp. With the tarp flush against the back of the rack, you could cut holes in it aligned with the miners exhaust fans so all of the exhaust air can't be recirculated into their intakes and could be vented right out of the window and kept separate from the rest of the room using a tarp on each side of the rack and over the top directly venting all of that hot air out the window. I can't imagine that more heat would be coming out of the top from the boards compared to the exhaust fans though. I'm thinking that venting them how I described to get rid of the hot exhaust air, and then putting an AC in the rooms "cold isle" (the main room where the miners intakes are, not the smaller "hot isle" to contain and vent the hot exhaust air) to help deal with the hot air from the control boards would be sufficient. Yes I agree. The Heat from the top if I had to guess is probably only 5-15% 0f what blows through the body and out the back. By "venting them, I was refereeing to what I've seen a few folks do. That is...attaching a ducting tube directly to the exhaust fan and routing the heat out through that tubing. I imagine the heat at the control board is not going to immediately damage anything but the cumulative effect over time is probably not optimal. I'm sure that you, like me, want the longest life from these units and from what I've been told, optimal cooling and ventilation is the best way to help that along. I also use the tactic you are describing. I personally find it very effective and adequate. Although I don't use any AC on the cold side. I would if I saw temps getting too high but so far I have not had that. Even at 80 degrees F ambient temp on the intake side of the units. Pretty amazing how robust these units are. Especially the S9's. Just called a few colocation data centers, apparently it's not as uncommon as I thought for people to use them for mining hosting. They're going to get back to me soon to let me know how much they charge. I have no idea what to expect but so long as it's not some ridiculous price, I'm 100% going that route. Is it like a beautiful resort for your miners? Constant air-conditioning, ventilation, nightly massages, classical music playing for them? LOL! |

That is exactly why more competition would be needed in the market.
It would make companies treat hardware buying customers better.
Totally agree with that!! I think that's just around corner.....I hope. |

Personally I think Bitmain shot themselves in the foot this time, by being too greedy with the selling of the D3's.
I think they just did not want to miss the train on the X11 miners, as other companies started selling them.
So they decided to make as much money as possible.
Bitmain knew full well as they received the orders by what the difficulty % would go up.
If they really cared about their customers, they would have not flooded the market with their units.
I for one will not support them anymore, because what will stop them from just doing the same thing with the next ASIC miner they release.
Just my 2 cents.
Bitmain is in business to make money. They didn't do anything wrong. They are the best ASIC manufacturer in the world right now. It's just the free market of supply and demand at work. Nothing to take personal. I'm pretty sure they won't miss your support. You'll be the one missing out. If folks be careful and remain disciplined with their expenses versus revenue they will survive. This is just like any other business. Some folks got lucky and hit the early batch lotto with the D3 and the L3+, but in reality, it's just not that easy. Nothing is. You don't just plug something in your wall and make $168.00 per day. At least not for long. We'll see the same metrics on the next technology upgrade. We saw it on the last one. It just wasn't as well known then. Roll with it. |

Im actually jealous of the October batch compared to September, at least they got a 1100$ discount, ROI may be easier for them. Depends on future difficulty but hopefully most yet to be shipped miners are mining now which won't skyrocket the hash rate too much. Bring on helium
From my perspective there is one glimmer of hope on the D3 front. Many, many, many of these servers ended up in the hands of resellers speculating on their aftermarket value. That fell off of a cliff very rapidly and many of those have not sold. Nor will they. Until those people take their lumps. Every day you see several D3's and L3+'s, offered for sale in the marketplace forum, Ebay, Amazon etc etc.. Still at absolutely ridiculous prices. Sooner or later these poor chumps will be puking those things all over the forums once they realize they are taking an ass whooping. Keep some cash handy because THAT's when you'll want to buy those units. |

Hello Guys,
someone can recommend me a PSU for the D3 since I could not buy mine in bitmain with my order.
This is where I buy some of my PSUs: www.parallelminer.comThey are reliable and have a good lead-time. This is an EXTREMELY USEFUL link. THANK YOU! Crypto Accepted. |
