New Miner X5 on BitFury 16nm chips

[KNK]

- have datasheet of chip

As this was not posted yet officially, I guess you can't share it because of NDA. Can you at least post the footprint used from both 16nm and 250nm chips and on which pin is the CLK for 16nm - that would be enough for me re 16nm.
For the 250nm one ... I think it is not the same chip as on StringPowerBlock.pdf, but the same one as on 1block_short.jpg ... can you confirm please?

[Mitak]

In this moment we:
- have datasheet of chip
- working with the engineer sample of chip Bitfury 16nm
- have finished elaboration of the board

how much you paid for access to docs and sample

[gablay12]

If you agree to invest 1 M USD and you are an integrator you may reach the sample chips and docs.

I for one am extremely excited to see what Bitfury has to offer here in the coming few weeks. But I'm probably not going to buy until I see how profitable they become as July starts to crawl closer.

Its real pictures for a hashboard Miner X5
I dont payd anything.
Have you question, I will try to answer

[kilo17]

I am not an engineer but that board design looks crazy to me.  Why on earth would there be 26 chips on 1 side of the PCB and 3 on the other side. 
That looks like it would be a disaster to cool and the traces look whacky with the square layout of the chips on the side with 26.

Who told you that these three chips require cooling ?

26 chips go with thermal paste to heatsink , such as Antminer S5.

...

But where to take the S3 owners screws and springs for it ?

I see that it is only suitable for Antminer S5 upgrade, not for S1, S3 or C1, where the blades are the other way around.

[HagssFIN]

You would have a lot more potential customers if this would also be a suitable for S1, S3, and C1.

My personal guess, which can be confirmed or rejected from ukrcoin, but ...

The 26 chips are the 16nm hashing chips - they will be cooled from the topside with a single large heatsink as there are no different voltage levels there (like it is at bottom of the chips). The board is designed for 12V operation and the chips are in string, so 12V / 26 = 0.4615V per chip (or even lower as there is MOS transistor and current sense resistor to control the power with their own voltage drop). The problem I can see here is that this voltage may not be enough for 100GH per chip and 2 boards will have a hard time to deliver the advertised 5TH, which is 2.5TH per board or 96GH per chip. On my opinion (according to the DEMO videos from Bitfury) for that hashrate 0.477V are required or a higher clockrate per chip, but only the test will show if it is still stable then.

The 3 chips from the other side are just communication chips and they do not produce extensive heat, so no cooling is necessary for them.

What you can see on 'hashside' of the board are not traces, but the borders of the power pads (VCC) per chip, because they are chained and the (two lines of) white dots at the edges are vias to connect VCC of one chip to GND of the other.

For more technical detail information ask on the site http://en.hotmine.io

[Subw]

so which antminer frames (S1, S3, S5, C1 ?) will accept this boards?

[ukrcoin]

Yes it is

[Subw]

Yes it is what?
All antminer frames are supported?

[ukrcoin]

We tried with s1 and s5

Unless there is a reseller in the US I won't be touching these. The Ukraine is like the scam/hacking leader of the world.

The Ukraine is like the scam/hacking leader of the world.

Based on what? One could argue that is the US in the Bitcoin world - we've had BFL, Garza etc.

So I send you 6400 in btc and wait until sept 2016

 I get 28th  that burns 3.3kwatts of power  and of course provide a boiler to heat my home.

3.3kwatts will give about 13,000 btu of heat.



Model
 
HOTMINE TOP 28 Thash
Hot-water boiler (miner) is mining bitcoins and heating water. You can use it in combination with batteries, fan heater or other equipment.
 
100% economy on cost of the heat!
 
3,3 kW electricity consumption — heating up to 50 sq.m. of your house (when using a fan heater)
Computation Power — 28 Thash. Bitfury's 16 nm chips are used.
Water temperature — 65C
Applications: heat-insulated floor, heating, reheating, DHW
Release date — September 2016, preorder available — $6400




you can buy 7    s-7's for about $5200  and get them in 1 week.  add in 800 in psu's and you spent 6000 and get to mine from march 4 th to sept 4th

with 32th of hash.  the economical calculations are just not in favor of your gear.  for 6400 I want it  in about 1 month  not six.

dude no one forces you to buy anything so you can STFU

do you have statistics or something to prove your words?
i bet they will ship from china but let's wait for ukrcoin to elaborate on this

Okay I will do just that.

But before I shut up.

My first bitfury order back in the day I preordered waited months order was cancelled did get a refund.
My second bitfury order was delayed I preordered  waited and order was cancelled did get a refund.
My third bitfury order was delayed  I took delivery and the gear was obsolete because during the delay bitmaintech came out with the s-1.

Asking for a six month wait on a preorder is a great idea for  the seller.

I love how someone with extensive knowledge and know how makes a very sensible argument, and a nobody goes full retard on him.  Absolutely nothing in retort besides telling him to shut up.  It always amazes me how more ballsy people get behind the veil of the internet.

Good call Phil, these are overpriced for where they are at in development and the risk involved with sending money to people who have yet to prove they can make a miner.  Although I am not buying gear until after the halving anyway, if I was, I would take the Bitmain stuff now over a promise in six months.

EDIT:  NVM, he clearly has a vendetta against Bitmain based on looking through his post history, probably an alt of someone.
