DragonMint T1 16TH/S halongmining.com

[philipma1957]

okay so it has parts from an s-9 and parts from Innosilicon

so like Yoshi told me many parts are similar from various miners.

My HP omen gpu miner has  2 1080ti's and an intel 8700 cpu
Does that make it a Dell Alien gpu miner because the dell has 2 1080tis and an intel 8700 cpu?

So I do not know what the bother is.

Now for them to do well  it needs to do 16th at 1300 watts at the wall.

If I ever get my demo I will point it at -ck's pool and try 3 different psu's on it. (not at the same time)

till then I got nothing.

[NotFuzzyWarm]

Do be sure to try them on both an AB tweaked pool (slush) and one of the far more common non-AB pools

That's pointless. As I pointed out they do NOT run without AB.

Then until all the SHA256D pools support AB - and frankly I hope most won't - that makes it a definite no-sale for me. Oh well.

Comparing pc parts with asic hardware is not that simple.

When you design your ASIC hardware, you design the whole set all the way from control board, hash boards, chips to be custom made and compatible with each other.

But it is possible that Halong and Inno has had some partnership deal in which Halong has got an access to Inno designs and have that way been able to implement the Inno control board in the Dragonmint unit.

like asrock has with intel
or asus with intel
or evga with intel

or any mobo that uses intel.

[HagssFIN]

Just one thing that confuses me in this, is that why both parties (Halong and Inno) do not want to confirm anything about this OEM or other partnership deal?

Revealing the fact that the control board design is very much the same got me kicked out from the Dragonmint telegram chat room.

What are their reasons on this?

[NotFuzzyWarm]

What are their reasons on this?

Inno - who knows.
Halong - given their very odd ideas of how publicity works and their hubris, seems perfect for their playbook.
Wonder how they are going to approach the Patent application from Intel filed today for a BTC hardware accelerator? Even though it makes my head hurt reading patent applications, it sure looks and feels like another variant of AB to me...

My five units are running at various speeds and power draw: 1489 watts, 1521watts, 1656 watts on 220V single phase and one at 1688 watts 110v using an EVGA 1600 G2. (5th unit I have not checked wattage but pulling 7 amps on 220V). room temperature is 70 degrees

Hashrates showing on Dragonmint miner status page: 15.13TH/s, 15.86TH/s, 15.38TH/s, 15.42TH/s, & 15.40TH/s  (slushpool)

Decent I suppose at 1489w and 15.13TH/s, but not really all that impressive. Especially with all the fuss about the asicboast and FlushPool.

okay  the 110v evga 1600 g2 is lacking so it is worse at 1688 watts -  I suggest getting something else for that or using a 700 watt on 1 board.


but all of them are higher watts  then I thought they would be.

so what psu's ?

do you have a delta 2400 watt psu on any of them?

or all antminer ap3++

I would love to test my demo when I get it to see if a 2400 watt delta is better

other four rigs are using MyRig/Halong PSU

[philipma1957]

yeah  which rates  at 1600 watts.

and while it may not burn up at 90% of its max  it loses efficient factor.  It may only be silver at high power use.

I would be willing to say the delta 2400 watt or the ibm 2980 would do a lot better
 maybe  1400 watts vs your lowest at 1489 watts

good thought, do you have the IBM 2980 as well to test with?

If your theory is correct, would be worth swapping these out

If I get some spare time, will try Bitman 1600w psu and check for any improvements in power consumption

[-ck]

It's fair to say that the code to tune for optimal hashrate at minimum power draw is still in development, and these are the first public runs of silicon so I expect hashrates and/or efficiency to improve successively with later ones, and firmware updates to improve things slightly for existing ones. Small nm ASICs are extraordinarily fussy and tricky to tune.

yes I have

 the ibm 2980
the ibm  2880
the delta 2400 --------best server psu ever of the 15 different ones I used
the hp   2000
the hp   1800

the corsair  axi 1500

the bitmain 1600

my guess is  the 2000 watt or more are better servers

such as the ibm 2980

and the delta 2400  will be under or close to  1400 watts.

if these do 15.5th at 1400 watts

vs the s-9  doing  13.5  at 1400 watts   they are a big improvement.

Still waiting for the demo  to show the side by side comparisons but no one got back to me with a tracking number.

PCB designer here...

When I look at the side by side boards I see something that was shared.  No one would spend so much time to accidentally make a board look that similar.  It would take much more effort than just designing from scratch.

When we see similar boards we count the things that are the same in terms such as "a few", not the ones that are different.    If they were designed independently someone would have had to go to a lot of trouble to make them so similar.

I've had PCBs copied and reproduced.  This doesn't look like that.  This looks like someone had access to inno designs and made slight modifications, and routed the modifications.  This is far different than the car examples, or both boards are green memes that people have been posting on twitter.  The examples of both intel based motherboards having the same chip-sets just don't apply.

The level that boards are identical is just embarrassing.

For a couple grand they could have reverse engineered the PCB, turned it into a schematic, made their own layout, and at least made it look like they were trying not to copy someone.  There are lots of contractors who perform this service in China.  Of course the US has them too, but they are more expensive and typically prefer to do it on designs a company owns but lost to obsolesce.

I assumed an average of 1550w based on 1480+/-8% and experience with S9s.  1400w could be reached with a few percent, but I'm also guessing that the yield won't be nearly as consistent as what you could expect from Canaan.

I'd be interested in knowing if the connectors on the power supplies and receptacles on the dragonmint are plated with anything.  I've been using a thermal camera images of my Canaan and Bitmain miners for preventative measures.

It's a prototype Innosilicon BTC miner. How Halong has obtained these is anyone's guess? Even the Web UI is just re-skinned/re-shuffled from an existing Inno one: https://i.imgur.com/KzC3RoP.png. If Innosilicon wanted to compete with BITMAIN through Halong as their proxy, surely they would make better effort to hide the association?

Do you guys think there is even any ASICBOOST in the chips? We are not seeing the kind of performance and efficiency gains one would expect. We need some experienced people to reverse engineer this hardware and see what is happening. Something is not adding up here.

Can someone who got their Dragon take high res picture of chips without heatsink ?

Not without a heck of a lot of work.
