Just apply a new sticker on top of the S7 miner and undervolt & underclock it a little and voilą you have a 'brand new' V9 miner.  Grin
802  Bitcoin / Hardware / Re: Antminer V9 4TH on: February 07, 2018, 11:43:52 AM
My opinion is that BM1580 is just a rebrand name for the old ASIC chip BM1385, used in the S7 miner.
803  Bitcoin / Hardware / Re: Antminer V9 4TH on: February 07, 2018, 11:18:20 AM
There will always be clueless people to buy whatever Bitmain decides to sell, and we can't do nothing about it..
804  Bitcoin / Hardware / Re: Antminer V9 4TH on: February 07, 2018, 10:38:10 AM
V9 use 135 of BM1580 chips.
S9 use 189 of BM1387 chips.
S7 use 135 of BM1385 chips.

Well, it is not a new thing that manufacturer renames a old design with a new name.

We have seen this before with AMD and their Radeon GPU series.

well if you look at it closely, you can see the white sticker on top of the black/yellow one and it 's off!

Lol true, that's lazy.  Grin

They have just put a new sticker on top of the old one.

I see it very possible, that Bitmain is moving a lot of operation to the USA and Switzerland.

There is a thread here already https://bitcointalk.org/index.php?topic=2882229.40

Nothing new here to see, it is most likely just a renamed S7, which is undervolted and underclocked.

Here is quote of my post:
This V9 miner is actually most likely just a S7 underclocked & undervolted..

Back in the 2016 I tweaked a S7 to perform 4.2Th/s at 1066W (at wall) power consumption by using methods in this guide provided by sidehack.

Link to the guide thread: https://bitcointalk.org/index.php?topic=1504228.msg16258852#msg16258852

I used one these hex files with PICkit3 for undervolting and underclocking a S7, batch 9  and everything went smooth.
I sold that miner but I'm going to do the same thing again soon to a S7 when the S9 arrives and I rearrange my miners and PSUs.
Here is my setup:

Antminer S7, 640/670mV,  4.223Th/s (60 min avg), 625 Mhz

Power supply: Enermax Revolution 87+ 1000W
Voltage: 227 VAC
Current: 4,7 A

Power (at wall): 1066,9 W

Well, a big LOL at the NDA in my opinion.  Grin

If you can recognize hardware like I do, after I've had numerous different machines from different manufacturers,
it only takes few minutes to realise that it has Innosilicon hardware and software inside.

I find it odd that they are time after time avoiding my thorough question about the exactly similar design with Innosilicon hardware & software.

Usually when I ask this in the Telegram group chat, they just talk about different subject or post memes/emojis.

...and a new Antminer V9 in town!

To the few people that pm'd me that I didn't get to reply back to its because I can't send too many posts back to back and have been busy,

My partner and I personally flew to Wuhan China to meet with Innosilicon after our investigation into Halong ended in us deducting that it is a fictitious company. We decided to run A6's in our mine as we could get them immediately, they were the most up to date on the market and the track record was there.

I thought we were going to get to the company and we would be in a little room and it would be dodgy with them questioning us the whole time. In reality, it was quite the contrary; it was a large 8 story building with floors dedicated to r&d, testing etc. Lets just say we were very impressed with our visit and our decision was made.

Here is where the info for you all comes into play and this is the last time I'm going to try to help everyone; it seems like some people just can't be saved even when the truth is in front of their eyes.


While at Innosilicon's Factory, I saw the unit that Halong is trying to pander as their own, it was the exact unit gram for gram and it  was running the exact stats that they showed in Halon's video. It is simply one of Inno's future products that I imagine will be releasing this year, Inno told us personally that the unit in the pictures was their product and that they have no relation what so ever. They hadn't even heard of Halong or the Dragon-mint until we showed them the pictures and filled them in at which point they told us what I just highlighted.

There is no conspiracy that they are working together, they simply got one of their units and are trying to pander it as their own and make as much money as they can while they do it.


If this doesn't put an end to it, Cest La vie. You can't save everyone ....
Thanks for posting,

my research and your post tell the very possible scenario what's happening here.

It is most likely a rebadged Innosilicon miner.

Whether they (Halong) will sell it for real or just run a scam with it, is a another question.


No wonder they don't like showing pictures about both the hardware and software,
since it's a Innosilicon design.

Gathering publicity like this, it makes them no better person than Bitmain is.

The original idea for this was to be better to people and Bitcoin than Bitmain is, wasn't it?

Doesn't sound like a very handy and useful idea to me..
816  Bitcoin / Hardware / Re: DragonMint 16TH/S halongmining.com on: February 06, 2018, 08:06:00 AM
Still no transparent proof about the hardware, but hey, it did not stop Halong from releasing a third Dragonmint miner model already.  Grin

They now say they have a Bitcoin miner, Siacoin miner and also a Decred miner coming.

edit:

But I have to give them credit for releasing this video featuring Yoshi from Myrig.com company (formerly BitmainWarranty).

Phil, since you know Yoshi better, what do you think about this video?

I sent them e-mail too, I would like to help you guys but I don't know the answer for this.  Undecided

I've usually had good response when messaging with Ronald from Bitbank Group, so let's hope we can get some help to this issue soon.

Link no longer works?

You need to be at the Chinese webshop for the link to work properly.

Those specifications are quite unclear.  Huh

BM1580 chip?

It is for communication between control board and the psu.

I recommend keeping it plugged in.

But if my PSU if faulty and can't handle 3 hashboards, I will have to use different PSU, and there will be no communication between them? I wish this is explained a bit more by Pangolinminer. What's the purpose on that communication?

The control board is controlling the power supply. I don't know more about it, since no documentation with exact details about that communication is available.

I doubt it's any help, but here is the Whatsminer M3 user guide: https://drive.google.com/file/d/1lWv1mYZoHdSurfNGx6DxBIYj34MawzCs/view
