Maybe Slushpool is connected to this project by funding it and that is why mainly the Slushpool is advertised?

Maybe Slushpool is one of the Halong Mining owners?

Like I've stated before, this whole announcement, reeks of Corporate Shenanigans.

[Sandal_Hat]

I dont mean to be a wet blanket but there is no notable increase in hashrate in Slush and Ck pool. Slush and CK pools are the only pools that can take dragonmints. Hashrate for slush should go through the roof it they sold alot, especially considering how small slush is to the total hashrate. Furthermore, alot of slush and CK pool hash will be due to cheap S9s flooding market. Thus, the logical conclusion is that they didnt sell much miners. [Emphasis added.]

Although it is not conclusive evidence, we have some reason to believe that Halong Mining's sales so far have been massive in terms of revenue, which I noted weeks ago, but I thought it might prove helpful again here. Unicornflex, a member of this forum, shared this analysis in February after he and I compared our DragonMint order numbers from our Halong Mining receipts. (See quote below.) We placed orders online right at about the same moment, and he later placed multiple additional orders. It seemed to us that Halong's online order system was using sequential order numbers. If our assumption is correct, we can have a rough estimate of Halong's number of sales. Since the minimum order quantity requirement was five units for quite some time, we can also estimate Halong's minimum total revenue, which we estimated was more than USD $50 million (as of early February 2018).

Our most recent estimate is that Halong has sold more than $50 million USD worth of DragonMint miners, based on Halong’s minimum order requirement of 5 units per order and Halong’s usage of sequential order numbers in its online order system, which together reveal an approximation as to how many units have been sold. Any large farms that invested in upgrading their equipment with DragonMints could easily have [pushed] total ordered units to more than $100 million in sales.

LOL. I just realized u are also someone who has all his posts in only the Halong thread only haha. It is ONLY such accounts people making huge marketing claims of great sales omg. The amount of such accounts here is huge. And there is No basis for such claims. It does NOT show in hashrates on pools. And this is such a bad time to sell miners that even the market leader is slashing prices drastically to sell miners haha.


Unicornflex is an account with just 2 posts, both in Halong thread and praising them.
https://bitcointalk.org/index.php?action=profile;u=197256;sa=showPosts

It is amazing that u can even notice his ONE post in a 90+ page thread claiming 100 million sales especially since his post was made on 7th Feb and your first post in Halong thread is 21st Feb.
And now he appears after u speak of him HAHA. His 2nd only post.

I notice it is just all your newbie or Halong only accounts talking to yourselves here for marketing purposes. This is not seen anywhere else.
It is also amazing that u supposedly track supposedly their order numbers. Something easily faked and no one tracks this. These people had at most 600 in their telegram account then and most were just not believing their existence. Any ICO had more people lol. No evidence but tons of claims haha

Oh it get better if one looks too much at another thing. MyRig.

Note default pool choice 2 is pointed at a MyRig pool. Just went to MyRig's site and among other things missing is any mention of them running a pool. However, as Bitmain Warranty they did operate several data centers for hosting and no doubt have now just gone 1 step further and made their own private pool as well.

So the failover is to a MyRig slush fund? Also missing are any Bitmain products - all are shown as Out of Stock. Even PSU's. Funny, Blockforge has s9's and a BM altcoin miner in stock as well as BM PSU's. So do other reputable non-ebay distributors...

Most of the MyRig site is under construction but what *is* there is all about how wonderful it is for MyRig to be working with Halong. BitmainWarranty began their changeover to MyRig when? Around late last summer? Wonder if the folks behind Halong/Little Dragon LLC are who bought Bitmain Warranty.... The timing rather fits considering the change to MyRig was done just a couple months ago.

No accusations here, just sayin.... At least the hardware does exist in quantity so props to Halong for that at least.

[Sandal_Hat]

everyone can check testing numbers right here.

Is there an issue because it is off again? It just shows 12.4G in last 1 hour

Well with all respect - he did say he was taking a shot to show the default pools.  Not make any hashrate claims.

Nope. He posted that picture. He said it is the defaults and his next post said it is on specs. How is that not misleading?
Anyway, this fellow, his review may just show very good numbers somehow, just like their first vid that shows 1460w and 16.2 TH in Nov/dec. He is probably affiliated.

Previous reviews of 5 dragonmints by a forumer shows lower hashrate and higher wattage...

no the demo came in and is mining here.
http://ckpool.org/users/16yLHLoeyuCLPMXkVpC3gyrRYvwRGwjKJr

this is a completely different miner then the one tested yesterday.
I had a very busy day today.
Multiple delvieries of gear all due on fri showed up today.

And My kitchen sink clogged  which means I put on my roto-rotor hat and spent half the day getting it to unclog.


I now the demo from yoshi
I also have the demo from a forum member.

so I am testing the demo from yoshi.

poolside new demo came today

http://ckpool.org/users/16yLHLoeyuCLPMXkVpC3gyrRYvwRGwjKJr

gui below

using the myrig psu

in all fairness there is a firmware I am yet to try

I see. Maybe if u are free, can just test both dragonmint units and not just the one from yoshi. It seems some units may have varying performance, as seen from the guy with 5 units.

yeah I will do one test on yoshi demo
using same psu from myrig

after 20 minutes it dropped to 15.58th

and pulls about 1650 watts on my kwatt meter

almost exactly the same as the first unit tested yesterday.

so the 15,58 to 15.7  is okay but the power it to high.

I need a link to firmware to see if it gets better.

[philipma1957]

I am frustrated.

I do 15500 and  1650 watts

give or take 2 %  on multiple  units  with multiple psus.

neither unit tested  is at spec.

1650/15500 = 0.1064
1480/16000 = 0.0925

0.0925 x 1.08 =  0.09999  which means I am out of spec.

I will do more tests.

[philipma1957]

tired shutting them off and going to sleep.
I will bring them to solar array using different internet connection.

maybe they will speed up.

it is nice they do 15.5 or 15.6 th out of 16.0 spec  that is about -3%

but 1610 to 1709 watts   on four tests  with different meters = not so nice.

I have some titanium psus I will trust them in a few days.

1610 watts with the 2400 watt plat delta and 15.6 th my best so far.

to be fair all tests were 2 hours maybe I need do  6hr or 12hr or 1 day test.

[dimaze]

After over an hour of testing, the machine settled out to spec at the pool. I'll do some further testing as well, I primarily did a tear down today.

Amp draw @ 240v was fluctuating between 6.5 and 6.6 amps, which puts it at 1560-1584 watts. Bit higher ambient too.

I should have my general review done tomorrow sometime

[StevenMosher]

It's simple enough.

10nm

which fab?

how many masks  for that 10nm?

Answers to those two will explain a lot

I am really interested in hearing the answer to this question.  10nm with the ASICBoost?  I don't see the benefit.  If you had to guess, which fab did they use or do you think the whole 10nm is fabrication?

  10nm.  

   The first thing is most customers do not know the right questions to ask a mining company to ferret out if they are bullshit or not. So, I encourage everyone to ask the right questions about chips, fabrication,  etc.  If the guy doesnt know what he is talking about it will be clear right away.  

Speculations:  In the beginning a bunch of folks were saying it was a 16nm chip.  And some speculated that it was just
and overclocked S9. Hmm, dunno. The problem with it being a  16nm  chip from a new company is that TSMC would not give a new customer any wafer capicity.

How about  TSMC  10nm?  Well if they answer TSMC  10nm,  then that   fuels another speculation that buzzed around on twitter
that Halong  is  just a Bitmain  subsidary  and  it's Bitmain's method for selling chips. It also helps them clean up their
act  and  diffuse concerns about the concentration in mining. Information vacuums  are never good as they fuel speculation.


Maybe TSMC 12?  performance is somewhat consistent with that.
 
Intel?   Nope.  


Samsung 10nm.   From a performance and shipping standpoint samsung 10nm makes sense because  there is an apparent  yeild issue ( there always is )  and because there is  what looks to be a voltage leak problem which could lead to excessive power consumption. You'll get chips that run at  sub  .09J/GH  and  devices that run above this.  If you can just run the thing through a variety of frequencies and see what happens to the power consumption that will be  a good clue. Maybe they can tweak the  the process to reduce the portion of chips that might have this issue.  Ideally,  they would do  different SKUs,  those that run between 15 and 16 and those that run faster. Hard to do unless you have big volume. In any case  if it is samsung 10nm, then the best thing to do is just to address the performace variations and explain what you are doing to reduce/improve the situation. If they are tweaking the process to run at a fast corner (for example), just tell folks. We are tweaking the process.
If you build chips  it is what you do.

In the end someone somewhere will decap  chip or take it to their dentist for an xray and post the dimensions. I should
do a bounty on that.  If you know the dimensions of the bare die that will tell alot. Has anyone decaped a Bitmain chip?

Finally, the other thing is some guys  use  chip specs  to derive machine specs.  That means you might spec  16TH .07  from
the  single chip performance  ( averages of lots) but when you actually build a machine  its  15-16TH  and  .1  at the wall.
what we do is a little different.  We spec machines  after they are built and tested. So  13TH,  actually means a tested
MINIMUM  13, and empirically  75% of the machines  run at 13.5 or higher.   Ideally there would be some kind of standard
benchmarking  but I dont think the industry is ready for that.

Anyway,  more information from everyone, open information from everyone is always a good thing.

I can do the x-ray.    I don’t have access to a microfocus tube at the moment, but I can just back one of the big ones up a lot. Working or not, on the board or not...let’s go!

[-ck]

They've been massively rewriting chunks of code for the driver meaning a lot of my work hasn't yet hit the firmware. I've just finished refactoring the first solid working version of the autotune for these which is working pretty well now so hopefully you'll get to use it in a new firmware soon. It takes about half hour to tune and will be running by default in future versions; it tunes every startup. If you're looking for more efficiency, this should help provide it  I haven't realised any dramatic hashrate improvements yet though.

Gear seems to hash at 15.5 pulling 1625 watts
I will be waiting for some firmware links.

It is not the

16.0    at 1480

I did get a b52  which has nothing to do with this thread.
but it is from the same company


the b52 is doing

4.10 th spec is 3.83th

at 1500 watts spec is 1380 watts.   that is good enough
