Topic: DragonMint T1 16TH/S halongmining.com - page 36. (Read 87857 times)

every one of my six is at 1610 to 1679

all over +8%

every  miner is about 15.4  not 16.0

that is -3.75%

so  it is off close to 12%.  

frankly I can live  with the 15.4t  vs 16.0t

but the  1610 watts to 1679 watts  vs  1480 watts is an issue.

all my circuits are 30 amp about 238 volts  that is 7140 watts x 80% = 5712  watts

4 x  1480 = 5920 watts  that is  83%  close  to okay .  Ie  it will work if it is cooler then 85f-88f

4 x 1610 = 6440 watts  that is  90% not that close  and I know  my breakers will trip  if it not 60 f or cooler.

so  I have to do  different setups.

I really wish  they went  with  1300 watt baseline and claimed 14.5 th

if it then came in  at 1450 watts and did  14 th  I would be fine.




Now these are first run  maybe a bit of tweaking  and they get better.

They made a  B52for SIA it  does 4.15th  and says 3.83th  so that is better then the spec claimed.

That's fair, I hadn't seen their advertising blurb beforehand. The new firmware will bring it down, but not 1480 at the wall. The efficient (undervolting) tuning mode will be lower power than 1480 but definitely won't be pushing 16TH at the time...

The unit's rating on the side says 1680W. 1600 draw at the wall is not 1600 output, and I actually know these units are conservatively rated.

To be fair 1480w + 8% is 1598.4w

What I find a bit scary is they are selling these with 1600w power supplies and putting 100% load on them. That sounds like a real bad idea.

could be this:

"DragonMint T1 Miner

The DragonMint T1 is the worlds most efficient Bitcoin miner, operating at 16TH with AsicBoost technology inside for greater power efficiency.

At the wall power consumption of with DragonMint 1600W PSU and dual fans 1480W @ 240V at ambient temperature 25°C. Variation of ±8% is expected."

By the way, the unit says 1480W on the side of it. The myrig PSUs are rated at 92% efficiency. That would work out to 1608W at the wall. While the hash rate might be lower than advertised, isn't that close to spec on power? I'm not making excuses for them, but I'm wondering if everyone's expecting them to be 1480 draw at the wall?

Around 70-75 degrees.

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:

hmmm i thought ur hashrate at the pool was determined by how many shares u submitted to the pool in a set amount of time. that means if u use asic boost u get to cheat around and send some extra shares bumpin the hashrate the pool sees by up to 20% right?? i thought it was the same as regular s9 mining in the sense that sometimes shares take a little longer to send sometimes makin ur pool side hashrate drop and sometimes shares get sent faster by pure luck and it makes ur hashrate go up slightly higher then spec. Since asicboost is turned on that must mean its submitting up to 120% more shares than it would in the same amount of time 100% would be sent that was how i interpreted that workin out. If you set the diff really high on a pool it takes longer to submit as well which also makes the hashrate shown go down. this would imply that the t1 miners hashrate isnt 16th/s like they said (excluding the facts that they dont mine to spec even with asicboost active) its really 12.8 about if the hashrate was at a perfect 16th/s. the power draw should remain the same with and without asicboost because the boost would just mean more shares r submitted in the same time frame but the power will remain the same constant rate aside from fan speed changes and stuff like that. activating asicboost doesnt reduce the power by 20% per miner.

i agree they lied and customers got less than they were promised. its a shame they had to ruin their rep like this. i hope they provide a resolution sooner rather than later. its already been too long to provide one but better late than never right?? otherwise who will trust what they say if they do this again??

I think you are misunderstanding how this asicboost thing works. It increases efficiency and lower power draw, it does not increase the hashing speed. 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.

Either way Halong has acted with bad intentions from the beginning. The fact that you cant even mine say BCH, or some other sha256 coin makes these miners even bigger piles of crap than first thought. This was never disclosed to anyone who purchased the machine either. All this was done while they shouted from the rooftops about how they were all about giving people choices and helping the bitcoin networks decentralization. The Halong guy can come in here and make claims about why they did what they did but it just doesnt add up.


Halong will not prove they can legally do business the way they are currently doing it.
Halong lied about the machines capabilities from day one.
Halong shipped miners that cannot meet advertised specs.


The fact that anyone is supporting them seems utterly ridiculous to me. A bad actor is a bad actor, despite them saying all the proper buzzwords to get the parrots in this community squawking along with them.

So everybody... How are you enjoying your new T1's?    Would love to hear the feedback....   Cheers

ooo ok if thats the case why arent folks more upset about this situation i wonder?? im not experienced with the ins and outs of this whole dragonmint story so i prob shoulda known this before.

it feels like they shouldnt claim 16th/s (even if it mines at that speed) because it technically isnt 16th/s because of asicboost. from what i have seen folks paid a pretty steep premium for these machines and got not only underperforming hardware but also less software compat than originally stated. thats seems wrong to me and i feel kinda bad for the folks that got duped by this. even with the known info that preorders from unknown companies arent smart it doesnt change the fact that the company lied about what they were selling and even after that havent done ne thing publicly to give back to the customers that they duped...

i dont think ck or slush r bad pools but i also dont think users should be forced to mine only at those 2 pools. even if they add more pools the fact that u cant mine other coins except btc is a kick in the nutz. im shocked others arent mentioning that 16th/s and 16th/s with asic boost arent the same at all. if they do figure out how to allow u to mine ppc with these machines u will only get 12.8th/s and thats ONLY IF the machine truely mines at 16th/s with asicboost which based on the info trusted folks have posted so far isnt the case. to be fair bitmains s9 is 13+ th/s without any sketchy hidden asicboost or ne of that mess. i feel halong shoulda posted the actual hashrate of the machine not the 20% bloated number they did post.

without asic boost the miner would do 12.8th/s if it did 16th/s with asic boost....does that also mean the power will be the same 1600w that people r seein or will that go down by 20% like the hashrate would go down?? if it stays the same that makes them way less efficient  than they promised. also if the s9 used asic boost and gained 20% speed wouldnt that make them even more efficient than they r now proving halongs claim to the fastest most efficient miner available wrong as well?

either way they seem to lose and lost trust but in the end i think folks r just happy that they got something even if it doesnt work properly and isnt what was promised. i hope they get refunds or somethin to make things right.

Yeah, people didn't know about it until official announcement in March 2018.

At the moment it is two different pools and BTC only.

Mentioning that the miner supports SHA256 algo is kind of incorrect, because it only does Bitcoin and two different pools at the moment.

DragonMint T1 product page - April 13, 2018:

This is true  no one new about asicboost until  Feb  of this year.

I don't have any issues  mining at ck pool
Slush is  a meh for me.

but  the gear does not do  16th or 1480 watts.

every one of the six I have does over  1600 watts on a myrig psu.  that is an issue.

not a single one of the six I have does over 15.8th long term.    that is an issue.

To anyone that purchased looking to solo mine BCH  they would be hurt.
To anyone that purchased looking to solo mine BTC  they would be hurt.

I didn't buy one of these... but wanted to chime in. The early buyers did not KNOW about the AsicBoost issue, so they bought not even knowing there would be use limitations going forward.

they did and it was proven to be true as well. the s9 is over a year old and others are just now touching the same sort of power consumption they hit goin on 2 years ago. I think that is somethin worth braggin about. this only covers miners that we know of and not ones running in private mines like bitfury...only ones released to the public.

now i do have 1 question for all of u t1 buyers....y did u decide to buy these when they only work for 2 pools?? doesnt that limit your choices pool wise?? also what if u want to mine ppc or something?? u guys paid more money for under performing specs that use more power and have less options mining wise all to tell bitmain "fuck u"?? im all for other options to keep prices of machines down. I totally get that and im 100% for that but in the end no one buys these with the expectation to not break even. no one gives money away (if ne of u do lmk and i will help free u from that burden) so im genuinely askin y do people want these machines and why are they happy with getting less than promised??

also doesnt asicboost provide 20% increases in earnings give or take?? does that mean the actual speed of the machine is 12th/s and not the advertised 16th/s (seems about 15.5th/s is a safe estimate)?? I guess it doesnt matter since they can only be used with bitcoin and on the 2 pools that allow asicboost. I personally would like to have the option of mining ppc bch or btc even if im going to mine just 1...having choices is nice.

lastly no having 3 cars hit 100 in 1.2 secs doesnt allow either of them to make that claim. using the word "fastest" doesnt imply its the same as others or leave it up to the reader to decide. the term "fastest" by itself is a direct statement saying it beats every other car out there no ifs ands or buts. now if they used "one of the fastest" that is acceptable since they arent misleading consumers but "fastest by itself would be a lie and leaves them open to hate from the car community and also legal issues in some areas.

The T1 can only mine on 2 pools right now and needs special stratum side options to work at full speed so it's like a production car that needs special fuel that isn't widely available to achieve that 0-100 kmh in 1.2 seconds 

If you had 3 production cars from 3 manufactures that could do 0-100 kmh in 1.2 seconds aren't they all the fastest production car available?

"Slimey" word fuckery is marketing.  Look at the manufactures that claim there car is "the most fuel efficient" and then have a long list after the *

BTW Bitmain also makes the same claim on their site.

Until the firmware is improved,
I feel that it is kind of false advertising to say that the T1 is the most power efficient machine available.

At the moment there are three different machines that can achieve about the same power efficiency level (~0.10 J per GH/s)
--> Antminer S9, AvalonMiner 841 and DragonMint T1.

yeah  i have 5 + 1 six

they  all do 15.2 to 15.6

if you really look at the pcb they are similar to the s-9 but they are not s-9's

I have firmware upgrade on two of them.   -ck says there will be more firmware upgrades
