@ Bitmain:
With the broken promises of updated firmware for S2 users & all the problems with the S4, PSU, firmware, etc, etc - I would like to see some proof that these will actually work as advertised before deciding to buy some or not.
1) Can you post a screen of one actually mining showing hash/error rate?
2) Will these work with all pools, including p2pool, or just a select few as with the S4?
3) Has the firmware been thoroughly tested this time?
4) What version of cgminer is bundled with it?
Thanks.
@ Bitmain: Pretty please?  Don't think that is too hard to do. Do they have some of them fabbed and running yet? What would be the requirements to show a pass for #3? |

The 11.5-16VDC seems to be when plugging it into e.g. a car's power jack (cigarette lighter), sometimes also found on airplanes (first class, maybe, though I think those are all standard outlets now as it is), and has nothing to do with output voltage.
It likely is 19V output as stated on the back (manufacturer probably knows better than the people who wrote the documentation/packaging/promo fluff) and at some retailers (e.g. maplin) who didn't just copy/paste the material, and that would explain the fan going faster than it's supposed to if that's pretty much just hooked up (semi)directly.
The jalapeno's mining portion itself is behind a bunch of voltage regulators, so that should be okay. Those voltage regualtors themselves may run hotter than they're supposed to, though. They may well be able to take it, but why take the risk?
Find a proper 12V brick. You can find plenty for cheap with plenty of oomph: 12V 5A, 12V 6A is fairly common as LCD monitors use those a lot. You can't use those as a travel power supply, but if you're buying something for that secondary purpose, you can do a lot better than this iffy thing.
5 or 6 amps is only workable if the Jalapeno is 5-7gh. The 3 chip Jalapenos need a 10 amp supply. First time seen BFL actually help a customer in these forums without resorting to name calling first. FTC has made them be more polite one other good thing to come from this TRO. More typically they just provide BS in a bag. But they charge you extra for the bag and the foam pitchforks. Whole threads full of zero customer service right here as an example: Issues with your BFL products?
Post below. Seems to be a more than a few smoking units out there.
 Gotta quote this one for posterity! Epic fail Bick... the guy bought 2 Jalapenos that were... wait for it... running TOO FAST! Damn dude, read! That is more Bruce Peterson's speed. |

 RETURN OUR MONEY BITMINE.CH CRY OUT CUSTOMERS!Steal thousands of coins from customers, then mine thousands more, pretty sweet gig if you want my opinion  They won't even swap my order value to cloud hashing so I can lose a little bit less than all of it. They don't even return my very polite emails for months now. Yup, big time fucking scam operation. Wow they won't even refund a measly ~9 coins but can mine 4k coins a month, with 3 times that yet to deploy~! |

 Someone is copying from HF's book. At least there is no need to go to court and spend money for the unlikely result of ZERO refund. FTC I would say is infinitely a better course vs. the forced bankruptcy but let us see who gets their money and when. |

...and the shit talking continues...
Does anyone know if there is any serious progress happening?
The only people who know are bound by NDAs, so everything you have left is IceBreaker. I suggest you to take what he is saying and multiply it by ^-1, you should get a clear view of the situation. Yes he has lied in the past. Has he not? |

If they have all this money, and are such a great company, why do they need PREORDER money?
I bought a tesla X and he did not need me to pay for it. I will pay for it when (and if) he delivers it.
It's really quite obvious if you've ever preordered hardware. They just want more money. They know that hardware be selling from stock for ~$0.2/gh by time they are finally shipping so they would rather have people pay current rates instead. Further can you really trust Cointerra given the last miner they put out on the market and the amount of complaints, refund issues and so and so on. I suggest steer clear of them on that alone. Looks like they completely removed the entire forum today also.
Oh no.. that is a clear red flag there. |
|
|
|
Can you tell me why this is self moderated?
Yet rarely actually moderated. One of the few that doesn't remove customers complaints. Given the spam that often occurs in these forums it is really mandatory for fabricators to set up a moderated thread. It is not an indicator of a scam or trying to bend the discussion away from problems in this thread. |
|
|
|
I'm really kicking my self in not going with Bitmain.
Still happy with my two units. Running strong even though the PSU in one crapped out after 30 days. Probably would have been happier with SPTech SP10s as well. |
|
|
|
So fan the flames? Given your own brand of spam why are you not going to get banned as well? Well off topic again. I don't really care if you are biased, not biased, or think you are unbiased. Why don't people post their thoughts beside us? I'd be keen to hear what consumers think over people fighting about you and your list. Seems to me you have about 10 threads and post in another 10 and this "fight" is spilling over everywhere. How about less you and more consumer discussion? Way off topic. Topic was rank bottom up. For me no real need to do that as I have stated in my own thread my reasoning. |

 [Thumbs Up] Reputable companies that you can expect delivery on time and to spec and will when they are in error provide reasonable and equitable relief to the customers satisfaction. In no particular order of importance. ASICMinerBitfury BitmaintechBTCGardenIASCICMINER (Asicminer Tube Miner Promoted by FriedCat)RockminerSpondoolies Tech------------------------------------------- [Thumbs Down] Disreputable companies that have provided late delivery or not to spec and will not or have yet to provided adequate relief to customers when the company is in error. In no particular order of importance. KNC CoinTerra Butterfly Labs - FTC Has Shut Them Down! See Link HashFast - Forced Bankruptcy! See LinkBitmineTechnobitBlack ArrowAMT- No Longer Shipping Units. See LinkVMCnTek - No Longer Shipping Units. See LinkMinersource* If you would like to COMPLAIN ANONYMOUSLY about a company feel free to PM me about that company so that your order from that company will not be put in jeopardy. As much as possible we will use posts made by customers with valid complaints posted directly in the hardware and group buy threads. ------------------------------------------- [Delisted Thumbs Up]Removed Thumbs Up Companies for Lack of Shipping (30 days without a post or units shipped) Twinfury USB miner Last Post May 26, 2014 One String Miner Last Post August 18, 2014 Nano Fury Project USB miner Last Post September 23, 2014 * Note that these companies or entities could develop new miners or start sales again and would be listed again. Links for threads give reasoning for lack of shipping and potential future projects. ------------------------------------------- [REASONING] Here is my biased and opinionated guide on purchasing hardware. I am only taking into account which companies have, in my personal assessment, a reputation for delivering on time and to spec without any significant or outstanding customer service issues. This is not a comparative chart it is merely a suggestion for consumers looking for a starting point rather than having to read through all the forums and other media. As the OP I am willing to move companies in or out of either area given sufficient complaints from customers or sufficient rectification of past indiscretions based sufficient CUSTOMER feedback from those who were injured initially. Feel free to discuss my biased and opinionated ratings in this a new moderated thread. I value the opinions of actual customers over the fabricator in every case. If you are here to troll me I will simply ignore you and delete your bs and move on to the topic at hand. This is a BIASED and OPINIONATED review of the companies still shipping units. If a company remains in the Thumbs Up or Down section I will review customer posts over the week and take a snap shot on the weekend and post their opinions with my editorial comments. This snapshot will look for negative posts for those in the Thumbs Down and positive in the Thumbs Up. Should there be significant changes to the company in how they resolve or fail to resolve issues then moving them from their current category could be warranted. Please note there are only two categories so you will need to weigh the merits on your own and determine whether or not you would recommend someone trust a company to deliver on time and to specification and will if in error resolve any and all disputes with their customer base. Let me know if I am missing any fabricators far or wide inside or outside bitcointalk remember NO SCRYPT or ALTCOIN. ONLY SHA256 box makers please. Obviously we will just avoid the outright scams that never shipped a unit right? And please make sure to debate vigorously if you feel I am wrong in my opinion. I will change it based on evidence of customer support for the company is fairly universal. Remember this guide is just the starting point. You can scan the list and agree or disagree and do your own research. I am giving you my best appraisal based on the reading of the bitcointalk forums and other sources. It is not a comparison of companies. It is just meant to give you a starting point especially for new members to source miners. And as always... read the Caveat Emptor by Gmaxwell and learn any purchase of mining equipment is a crapshoot at best. Good Luck hope it helps you avoid the pitfalls when buying miners. Oh here is a great rant about ROI. Some rants about Financial ROI by TheRealSteve. Although this Rant relates to stick or usb miners it almost seems to mirror the current situation for the home miner attempting to buy now. Further to mining there are questions regarding cloud or derivative mining contracts. Please review the thread by DrG here: https://bitcointalk.org/index.php?topic=739510.msg8355686#msg8355686------------------------------------------- |

or Teapot Tempest on Bitmain S4 or Serious Issue?Not sure what to think of the recent spam / hate / firmware / hardware issues with the S4. Is this a problem that has a simple solution or are customers being shafted? Need to look into this deeper. Opinions? Sample customer comment:Dogie, with respect - I don't want to hear the same thing from you as bitmain have been telling me & everyone else here for nearly 8 weeks. I have been in contact with bitmain over this issue here & via email this entire time, warning them about this exact thing happening, but to no avail. I know you get paid to provide answers, but please don't just repeat what bitmain keep saying - it's patronizing & annoying. Also, if you are going to post answers for & on behalf of bitmain, please at least try and make sure that your answers are correct & based on information from bitmain themselves. Some of your comments are quite simply wrong, leading to misinformation & confusion to other less experienced miners. Peace  EDIT: Example: https://bitcointalk.org/index.php?topic=796839.msg9129424#msg9129424Power supply replacement for the Antminer S4 Dear loyal customers, Today we have found out that the batch of power supplies shipped out in batch 1 and the first part of batch 2 Antminer S4s contain a critical defect. The customized power supply produced by AplusPower Co. Ltd is suffering from an unacceptably high failure rate and will be replaced with immediate effect. We take full responsibility for the problems caused and had not anticipated the unique loading conditions of a miner when selecting and testing the suitability of these power supplies. You can read more about the defect in the post below. We are now taking steps to ensure that customers are impacted as little as possible. The rest of batch 2 S4s will come with the improved power supply as standard. The following actions are being taken for miners already delivered:1) If your PSU has already failed:• Submit a RMA request with some pictures and proof [ie with your username in the photo] of your PSU’s failure to info@bitmaintech.com. • We will then ship a new PSU out as soon as possible. • We will also issue compensation to the value of 10 days of mining profit calculated starting from shipping date 2) If your PSU has not failed and the miner is running normally:• We will ship a new PSU to you. • Please do not contact support yet, you will receive an email asking to confirm your shipping.
Analysis of power supply failures within the first batch of Antminer S4sWe are sorry for the inconvenience you may have experienced regarding power supply failures, or even sporadic events of smoke from our first batch of Antminer S4s. We immediately set out to investigate the reports of failed power supplies from customers, and have made immediate changes to improve the quality of future deliveries. What happened with these power supplies is not acceptable. The power supplies failed by two different mechanisms: 1) Failed TR1 or TR2 MOSFETs on the power factor correction (PFC) circuitry.After investigations, it was found that the unusual service conditions a miner puts on its power supply was the cause of the failure. The repeated abrupt, dynamic loading generated significant current through the PFC circuits, eventually leading to the failure of the TR1 or TR2 MOSFETs. The replacement power supplies have significantly upgraded PFC circuits in order to improve performance and prevent a recurrence of the problem. 2) Failed MOSFET on the output Synchronous rectifier circuitA MOSFET on the output Synchronous rectification circuit was also found to be failing, due to the repeated and sudden load changes during the miners’ operation. During normal operation, the output MOSFET is expected to carry a current of approximately 30A and operate at a surface temperature of around 80C. The failing MOSFET was found to be heating up significantly further than this, causing the carbonized black PCBs and smoking thermal pad. It is worth noting that although a failed output MOSFET at high temperatures may result in some smoke from the PCB and thermal pad, it will not start a fire. All internal components of the PSU meet the requirements of the UL94-V0 flame retardancy standard, which certifies that any ignition will self-extinguish within a maximum of 10 seconds. In response to this problem, the sample filter in the Synchronous rectifier circuits have been altered to erase the excessive current, and so the MOSFET will not fail again. In addition, several high temperature prevention circuits have been added which will better protect the power supply from overloading and excessive temperatures. Moving forwardsWe always perform significant dynamic testing on chosen power supplies, however in this case we failed to recognize the special conditions and specific loading characteristics the miner would place on the power supply. Our testing has been altered to replicate and include these loading characteristics on any power supplies introduced in the future. Once again, we are sorry. AntMiner S3+ Batch 11 opens sale now, price has dropped to 0.535btc per unit, coupon is being issued Man I hate these 2 S3's I have that wont mine at 500gh/s.
I put them at 250 and they mine at 470ish, put them at 243 and they mine at 492.
You think that's bad ? You could be a batch 1 buyer that had 50% of his units unable to perform stably at 218.75mhz. Have 3 units that can only run stably at 212.5mhz. Plan on getting around to re-pasting them in the near future to see if I can't improve things. Ask me how annoyed I am. Especially when I emailed Bitmain early on in the S3 process and they assured me they would not be updating the S3's in the future to resolve the performance problems... And lo-and-behold the S3+ arrives a month later. Don't get me wrong, I'm a huge fan of Bitmain, and more than 50% of my hash power comes from their devices, but the S3 launch did not go as well as the S1 launch, it appears the S4 launch (Don't own one) has been problematic, and given anecdotes I'm reading here, seems the community consensus is confirming my gut-feel: Bitmain is losing it's way  Funny that I'm thinking of circling back to AsicMiner products for my next miner purchase... Liquid Cooled Miner C1: It is not only cool, but it is cool The density of miners is becoming more and more important as the rapid growth of the bitcoin hash rate continues. The industry is trending towards industrial level mining, which leaves home miners without much choice for compact and quiet miners. In response to this problem, Bitmain has developed a solution. The high end PC industry has used water cooling for years, and this expertise has been transferred to mining equipment. Bitmain is proud to announce our first Liquid Cooled Miner – the C1. The 1st Batch of C1s are priced at 1 BTC per unit (excluding shipping), with dispatch estimated Oct. 25th Specifications:* Hash Rate: 1,008 GH/s guaranteed * Power Efficiency: 0.8 Watt/GH/s at the wall * Voltage: DC 12V input, 70A recommended, no PSU * Water cooling block’s interface: G1/4-8 thread screw * One 14038 Fan working with water cooling block * Temperature: 38~40 °C at 25 °C ambient temperature * Noise: 40~45 DB at 25 °C ambient temperature * Ethernet connection, Stand alone * Certificate Compliance: FCC/CE Recommend Accessories:Note: Bellow recommend parts are not included in C1, but a purchase links recommended on bitmaintech.com.* Water cooling pump: Flow 450L/H, Head Pressure 3.0m, DC12V/0.5A, G1/4-8 screw threads, 1 unit * Radiator: Aluminum, 389mm * 128mm * 36mm, G1/4-8 screw threads, 1 unit * Fan 12025: DC12V/1A, including grills, 3 units * Transparent tubing (ID/OD): 5/16” / 3/8” (10/8mm), 3 meters * Coolant: If you choose an aluminum radiator, you can use deionized water with an additive, or specialist coolant. If you buy a copper radiator, you must only use specialist coolant. * Connectors: G1/4” thread 10/8mm fittings to connect the C1 to the pump and radiator. Either compression fittings or barbs 4 units * Spring clamps or worm drive fittings if you chose barbs, 6 units Note: 1) Power consumption: Quoted figures depend on your PSUs efficiency, the ambient temperature and the accuracy of the power meter. 2) PSU: You must provide your own ATX PSU. There are 4 PCI-e connectors for +12V DC input and all are required. Features:Stone alone: C1 mines are stand alone and do not require a proxy server or external controller. Setup consists of installing the water pump, radiator, filling the coolant, connecting a PSU and an Ethernet cable. Cool: Skving technology is used to design New-Style water cooling block. This allows for a large heat-transfer area, which keeps the PCBs exceptionally cool. Thermal Images’ comparing liquid cooling and air cooling at 1TH/s hashing power Quiet: Four hashing PCBs with 16 BM1382 chips per board are mounted to the both sides of two aluminum water cooling blocks, which are 250mm-long, 115mm-high and 13mm-thick. Each water cooling block contains 24 water channels for efficient heat transfer. A quiet fan works in tandem with the water cooling blocks in order to keep other board components on the C1 cool. Stable and Accurate: Customized and optimized from the design of the S3+, the C1 is designed with the same PCBs and is supported by Serious-Double-Block Liquid Cooling technology. This allows C1s to benefit from the stability and accuracy of S3+ required to run 24 hours a day with minimal downtime. Exquisite:Die Casting Forming technology integrates the common heatsink with a water cooling block, compacts two water cooling blocks working in tandem. These technologies are saving space and allow for 1TH/s of power in a case the same as the S3. C1 Pictures:

Any word on the AMD brackets ?
up HI, Yours will be out today. For others we'll put a product on the website with 0 price and no transport costs , you just have to provide your hex4m order ref Regards: Vesi Vesi, Please update me on the shipping date of my item. I dont know why contacting you is so difficult but I have sent multiple pm's and as you see Above I have requested you check them many times. I was told that my order was first going to ship out 2 mondays ago, and then I was then updated that It was going to leave last thursday. I have had no update since and nothing has changed on the technobit order site. Where is my order? I ordered with batch 2 with technobit in Mid July. Please send me a correct update. Why does it seem that you can get back to everyone else on this forum immediately but I sent you a pm and a reminder message above on the 11th and then again on the 14th but you seem to be ignoring me? I dont know whats so hard about keeping good business repertoire with clients.... Im starting to ask myself if my order is being "taken seriously" over there or not but it seems like it has been put on hold in favor of other orders placed after. If thats not true, please update me!!! I was in Batch 1 and have not seen any boards as of yet. How far along are we now? Where any boards shipped out this week? I didn't get my usual email from DHL that a package was being delivered... Still waiting on 67 more boards plus 1 rma.

Back on topic... That was weeks ago. Don't forget the many times that opie denied being a shill when I outright accused him of it. Deny Deny Deny, now he is upset that he got ripped off. However, he has been a good source of the private communications with AMT. I still think he's a rat, just trying to be a better rat now.
FYI a number of people can already vouch for where I stood even then from early on. Even while you and others were giving me shit. They can speak up if they wish. Otherwise you can go on with those ideas that I was a shill. This was not a solo act here. I think OPi has proven his worth and I hope he helps nail AMT to the wall. They deserve jail time for this scam. |

I think he likes you Bick"boy"  I guess. Let us see what mods say about this. I should have just complained about this way when they both started spamming me non-stop the very first time and then last week as well for 3 days non stop. I don't really care what he says basically all he is is a paid shill. Always one in the crowd who will lie for their free hardware. Look at BFL for example plenty of those types. Notice he doesn't post much of anything in this thread now after he learned about how close Marto and Josh were eh? Funny I wonder what the FTC might find after they take over AMT. When your wife and Josh's wife a best buds you don't seem to want to talk about that do we? I am sure there is a lot more there that will be uncovered when the tax man comes to check his books. Funny. Always about me never about the AMT issue. Is that off topic? I think it is. |

Nice size for stacking. |
|
|

The lawsuit has changed a bit others can speak to it, that. There are other things going on as well. Joshua Zipkin's situation is going to be worse than BFL's easy.
Be so much easier if the FTC got involved given what they are doing to BFL. |
