I was watching the price, and it went under .89 BTC as BTC went up, and now it spiked back up to nearly .96, even though the price of Bitcoin has risen. That's a 20% BTC surcharge now. (0.959101*8515 -- 8166.75 vs 6800)
Crazy!

This thread belongs in the altcoin section. That's a legitimate email. I'm happy with the options provided  Innosilicon has been delivering on these same miners earlier, too. Probably some sort of trade agreement (or dispute) between Halong/Inno |

This is not a new thing,
Innosilicon usually has the crypto/fiat money ratio set much in their favour,
and so you'll end up paying a surcharge when using cryptos for the payment.
This is pretty awful. For instance, the D9 is listed for 6800 USD, or 0.921515 BTC. The current market price of BTC is 8200 USD. You effectively pay $7557 (8200*0.921515), or a $757 (almost 15%) premium for paying in Bitcoin. This premium is really unfortunate for a company that is directly in the Crypto field, and I hope Innosilicon changes this approach. I'm not a customer of this batch as a result of this approach. |

Doesn't look like the BTC/LTC prices are updated properly on orders. Currently they're about 10-15% higher than USD pricing. I saw that too. I think they are setting it firm, at the time of posting. One of the things stopping me from pulling the trigger. Should I wait until BTC/LTC prices drop and then purchase, or will they then decide to magically adjust the price? Doesn't make any sense for it not to reflect market value. I hope they'll fix it, I was going to pull the trigger but I'm not paying a substantial 10-15% surcharge to use BTC/LTC. I've been happy with the Halong units, which are identical to these. |

Then there is Halong and Little Dragon Technology LLC's (holder of the AB patent) intense secrecy as to who actually owns/runs them. Hell they won't even give a City/Provence/street address for contact.\
There is an address that is accessible through public means! I hinted at it nearly a week ago in this thread. It doesn't give much information aside from potential upcoming models/names. The prominent figures are Yoshi and Drak, and probably other investors. Innosilicon confirmed their partnership with Halong. That, along with their ongoing deliveries, is legitimate enough for me. While I can see the perspective of people limited on where they can mine, I'm hopeful more pools adopt support for AB. I'm personally a pretty happy customer so far with my experience with Halong. I'm eager to see what their next moves are, with regards to general releases and next iterations of hardware (and firmware!) |

90.11W/TH on my test on efficiency settings. This is on 240v/MyRig PSU, on the beta firmware. Pretty good!
|

Efficient mode settings I had fluctuating between 14.2-14.3TH, and drawing 5.3-5.4 amps -- 1272-1296 watts over the course of over a day. That's between 88.95W/TH and 91.27W/TH, with a 90.11W/TH median at least on this boot and the beta firmware provided. https://i.imgur.com/XNN6RJO.jpghttps://i.imgur.com/0IXCFvL.jpgI'm pretty eager to see what type of specs this pushes out as the firmware is fine tuned. |

I've always been a chrome man myself I just shifted my unit to efficiency too. It's autotuning, and I'll check back in the evening with results. Same pool target as my above test for anyone that wanted to track it live. |

After about 3.5 hours of uptime on performance mode, the pool hashrate is 16.4-16.5T at the hourly indicator. Looks to be fluctuating between those numbers. GUI shows similar readings. Looks like my chain #1 is the performer, chain 2 has 22x the HW errors, and chain 3 has 11x. Had the other two chains performed like chain 1, it would be closer to 17TH! Amp pull is between 6.8-6.9, that's about 1632-1656 watts. https://i.imgur.com/3nZwyia.jpghttps://i.imgur.com/t69OAgA.jpghttps://i.imgur.com/IalK0cJ.jpgWith my preliminary testing, I highly recommend people upgrade to the firmware I've updated in the OP, I'll be putting these screenshots up there too. I'll continue to test the other settings. Excited with this new firmware!

Good call! We'll be able to compare after a bit. I'm off to lunch now, will check how it's been when I am back, including what the power draw is. GUI 50 minutes in shows it averaging around 16-16.25 at least, poolside 1h appears to be catching up to that figure. Promising results so far. |

Updated the OP with a close up of the Zynq chip there - second to last picture there on the teardown section. Let me know if any of you want any other closeups! Measure the DC voltage (if any) between the individual heat-sinks; while operating, but open, with additional external desktop fan providing additional cooling.
I'll try to accommodate this. Unit wasn't friendly with me when I had the fans disconnected or even connected, will try a workaround. Hi,
Does the dragonmint T1 new firmware offer any improvements in hashing speed, or was it to update a different issue?
Good question! I actually lost hashrate with the new firmware. It went from slightly above to below spec with the update. My recommendation at this point is if you have a unit that is hashing around spec, don't touch it with any firmware updates just yet. Halong indicated they're working on firmware updates to alleviate this issue. The GUI had welcome additions, such as individual chain ASIC status charts and a firmware checker, along with autotune capabilities. I'll throw those up here in the OP shortly. |

16th is still 16th, except the miners are all way out of spec. The only person i have seen post something saying its close to spec is dimaze, and he has shilled so hard and been so defensive about Halong he most likely has some kind of back channel connection that hasnt been made public. There is no other reason to argue with logic and facts. Quite honestly, if I had not met Scott in person (as he lives close to me), I would of waited till the miners were being delivered and in hands of consumers. I've been around the block with plenty of ASIC manufacturers. I felt fine with purchasing Halong units after meeting him, and I'm a very happy customer of theirs (Got quite a few B29s which are killing it in ROI -- thread available here for that). I've been fairly active in their telegram and it's a great resource. That's pretty much the extent of my channel with Halong. I'm sure anyone that was in a similar position with a manufacturer representative living so close to them would do the same thing, and I'm always happy to report here, to help the community. As for performance, my unit did hash at the advertised spec after an hour, and within variance of the power drain at the wall before tearing it down. However, after the firmware update and a calibration (which in hindsight, I shouldn't have done, it was hashing just fine), my outer boards began to perform worse than the middle one (about 0.25-35TH less each), this is more in line with what some people are reporting. Halong indicated they're working on Firmware updates, so I'm hopeful they sort out any issues people are having with the firmware. I'll be doing some more testing on my unit including some more detailed pictures, that will be posted to and updated on my review thread. I'm happy to test anything anyone can think of in that thread Here's a performance tab teaser they said they're working on:  |

There is a huge inductor on the PCB so it looks like
there is a DC/DC converter on board. Can you read
the chip number of the chips that are directly under
this inductor on the other side of the PCB?
I'll tear it down again soon and add a few more detailed pictures If anyone wants anymore details, let me know here! I'll update the OP with some additional details later. How many years of warranty does Halong provide for these units?
6 months from the point of shipment - more information on the terms of sale page hereYoshi did confirm it was Samsung and 10nm! More details this tweetHalong is also the only miner manufacturer I've seen take this many payments options. In addition to the standard Wires/BTC options, they take BCH, LTC, ETH, XMR, DCR, USDT! Great to see a manufacturer accept the currency they sell miners on. A good thing! |

Good review. Pls update us after few weeks how’s the performance ?
Also QUESTION: Since you opened the Miner , did you see SAMSUNG on any off the chips ? Curious to find out what the manufacturer or manufacturing process 10nm or 7nm??
Looks like there are heat sinks on both sides, you would have to pry them off of whatever adhesive they used. I would hate to break a new toy.
Will update after a bit for sure! I did try to pull off the heatsinks from both sides, didn't budge with gentle pressure. It's got some good adhesive, and I don't want to break the toy just yet! It would be interesting if each board can accommodate 10 more chips. You'll note one side is fully populated with heatsinks, one is missing 10 - perhaps airflow is sufficient enough. If so, on the 3 chain ASIC setup they have, that would mean an increase from 138 total chips to 168, nearly a 22% increase. I'd imagine this would create way more strain too on the power pull. 22% on top of even the 1584 I reported puts it at around 1930 watts. It also brings the 16TH spec to 19.5TH! We're going to need some bigger power supplies |

Hey Dr.Mann - thanks for looking out for the community. But your posts are really...long winded and annoying. Like all of them for the past 4 weeks. It's not about anything coming off as off topic or personal - you just write in an irritating corporate tone. Something a lot of us joined this community to avoid. You kind of sound like Karen, from HR. Maybe just give it a break? https://whohaha.com/karen-from-hr/Lol. This gave me a chuckle. I'd still have a drink with the Dr even though we don't see eye to eye. I look forward to him uncovering Halong's offshore legal service address in Belize  |
