Update/upgrade Antminer s5, boards with  BitFury chips

We would like to offer boards with  BitFury chips  16nm  to replace / upgrade Antminer S5

Specifications
Algorithm: SHA-256
Hashrate: 5 Th / s
Power Consumption: 550Watt
Power Efficiency: 0.11 w / ghash

Shipping out date: starting may 2016
Cost: reference to cost of terahash bitmain S7 minus 5%.

may is too slow  here is why right now the s7 is 1.7 btc  so lets say I send in 1.7 btc - 5%


that would be 1.615 btc    lets say you are truly honest and deliver on  May 15 ..   that is 88  days from now.

we will have 6 diff jumps in that time.

 so an s-7 is .3 watts

you are .11 watts.   6 diff jumps   of  10% and then the ½ ing in about 35 days  and your gear is in trouble for roi..

Say, that sounds an awful lot like something I'm working on.

only changing boards necessary?
what about the soft running the s5? will it accept the new boards?
very interested :)

philipma1957
Its only presentation
Price will be only after the prototype testing on april and no preorder.


joaogti36
Yes, you can change only hashing board on Antminer S5

when its ready let us know :)

would love to convert some s5's :)

If I hop on the hype train fast enough and if this thing is actually legit... I can see the possible profit. But its too far, I can dream on   ;D Hopefully not a fake.

Your business plan is wrong!

This is clearly a scam.

Why scam?

Statistics. Look at every other time a newb member's first post is a plug for the newest best hardware.

2 reasons it is likely a scam:

1- Do you have an arrangement with Bitfury to get the chips? If so could you please post some evidence you are getting the chips.  Also, I have received an email from Bitfury that states they are monitoring for scams.  I am sure they will chime in on this thread when they see it.

2- There are a lot of people on this forum that have a TON of experience and a TON of trust and they are not getting chips, how is it that a noob shows up with no history claiming to be able to make a miner with Bitfury Chips.  Now, if you are getting the chips I am sure you have a website that is associated with Bitcoin, could you link your credentials and the website.

Thanks

Also it seems your account is 2 years old and you were trying to be a retailer a year or so ago.  Are you still retailing miners in the Ukraine?  Also, I am not sure how shipping would be coming from the Ukraine but I would bet it is not cheap.  I will ask Bitfury if they have any partners in the Ukraine  ;)

I have a rule never buy from rendering.... and this is pre-rendering even on gear.  So it throws huge red flags up.   And it is on a new account.... again more red flags.

The truth of the matter is new manufactuers are hard to find, we have if anything gotten smaller and smaller on amount who make miners.  And this is likely to continue.  I would not order this gear.   I do think it's likely a troll though and not a scam.

Is he saying he is going to re-solder all the chips with the new BF Chips?    Do we understand how precision it takes to make these?

Can you expand on you plans for the Firmware & FPGA code on the Bitmain Controller board?

If SideHack manage to make an Upgrade board for the S5`s with either Bitfury or BW-LK1402 chips, then I could be really tempted to upgrade my 100+ S5.
That would be a winner for sure....following this thread.

We'll wait and see. Bitfury has told that they will reveal official partners, so it will clear all the scams out.

if sidehack  makes a board  that uses old S5 parts not the boards on newly designed boards with bitfury or BW chips yup . replacing the chips on a S5 board no.the way he said it , it sounds like he wants to do just that. it might be do able but why it's gotta be hard or Polly will be, i would think that's like putting something new on something old  it might make it worse..in this case chips are different then screwing a new board on a old heat sink or using the old controller .

why even bro with the s5 controller way it won't really save us any cash , maybe him but not us.


The whole upgrade idea is nice thu but the way he wants to upgrade doesn't seem to cool.


I'm not buying into this junk we have what one more month left to wait to see what really happens.

If you look back through the OP's posts you find.


And on that Website you find this Picture.

http://miner.bz/images/slide12.png

Which is remarkably similar to the picture in this thread



Rich

if im not mistaken wasn't www.miner.bz under a different name once, miner, something else that ripped off some others .

I can wait !!! . 30 some days is not really that long.

So he/she basically just copied asiabtc's (a.k.a. LIGHTNINGASIC) 3D model of the design for the scam.

Yeps, same here, no soldering any ASICS on and old board, thats a No-Go. New boards in the old S5 case and controller setup, Yes please !

New board with the same controller? How do you address that Bitfury and Bitmain chips use different comm protocols? I guess you have a translator chip on your board? How do you handle that S5 chipped with two different controllers - 18 pin and 16 pin? Does your board have both connectors just in case?

When you say 550W, is that power dissipation of the boards themselves or is that total machine power (including controller and fan, about 30W total) or is that wall power (and if so, assuming what PSU efficiency)? 550W wall at 90% efficient PSU and 30W in fan and controller leaves around 460W for the chips, which for 5TH puts you at about 30 chips per board and clocked to 85GH per chip (for about 0.094J/GH chip-level) assuming no power conversion. Of course, 30 chips per board gives you probably a string of 2x15, meaning 800mV per chip which, for these chips, probably means you're sorely overvolting it (that operating point is more likely hit at closer to 600mV). So you need a voltage drop in there - best case another 5% efficiency hit. So now we're looking at about 435W to the chips for 5TH - let's say 32 chips per board, clocked a bit shy of 80GH for 0.088J/GH (approximately). So 32 chips, and a 40-50A regulator, and either a darn good microcontroller or an FPGA to convert Bitmain protocol (coming in through one of two connectors) to something Bitfury talks, and Bitfury's comm multiplexer. Let's see a render of that, instead of a cheesy copy of someone else's cheesy concept render. Or better yet, some proof of actual dev.

SCAM Confidence Meter:   96% confidence


Evidence is building.


Recommendation:  Only purchase from official outlets.

I love this guy....I bend in the dust for Sidehack...kaboom and smashed up against the wall he was by Sidehacks points.

The OP put all of 60 seconds into a post and follow-ups yet apparently it was good enough to generate a full thread with people investing much more time than the OP.. Well done OP if that is all it takes..

I wondering when  side would shot this down .

lmao

"Hotmine" company engaged the development and production.
We are the exclusive seller of data miners.
I'm personally acquainted with these people, and do not doubt them.
Nobody does order of miners before it appearancing and testing.
The price will be compared with Antminer S7 for terahesh minus 5%.
This photo was taken because a prototype will be only in late March - early April, then it will be possible to make a real photo.
Consumption of electricity and hashrate taken from the calculations, the real figures will be only after the testing of prototype.
Package will include control board with hashboards for upgrade Antminer S5.

So replacing the control board also. That's a bit more logical.

I don't quite understand stealing a publicity render for a machine when, if you're modifying an S5, you could have taken a photo of an S5 and sketched new boards on to it for something a little more accurate and a little less shady.

But miner.bz says it is going to have all sorts of interesting products, how can you doubt them?  :P

Rich

id drop the s5 upgrade price some if it's even real but like i said 30 + more days then we see it all and how the home miners are gonna be etc .


I'll still get mine from Sidehack. !!!!. his maybe deals look much better and hes US based for better support, not that I'll need it .

what do i smell?   SCAM.. just give it up..
no one (hopefully) is dumb enough to fall for this in 2016. 
2-3 years ago, maybe you would get a few btc just for a few sentences.
you have nothing to show and nothing to offer. 

just ask for some btc to be sent to you and i'm sure you'll get some negative trust real quick.

Funny.

You guys all know that Bitmain will release something that destroys Bitfurys 16nm tech right?

They always have before and im sure it will be a mic drop again soon.

No one knows on them as they are not very public about things they work on, which makes sense as if they say we will have a new chip X date... sales drop on current gen.

We do know they listed another  batch of S7's so at least into march that is what they are making.  It's hard to say if/when they will have something new.  There has been no leaks or info to show they have a chip or will soon.

i agree. while i have been wondering what bitmain is working on i also remember, i think correctly, that we had with the s7---
----leaked rumors up to 7 months before hardwear in hands (s5+ and s7 talk)
----leaked tech info around 5 months ahead

so for no leaks (that i have seen) about new gen bitmain hardwear one has to wonder  ---
will they just DROP something?
will they use cheap power they have and mass setups to fight their battle with s7's?  is that even possible in this exahash stage?
oooo , excitting times
could get ugly or wonderful real quick.

o , and im on board with others here before me saying
"i'll believe it when it ain't just a rendering and words"  (and have btc waiting)

-watching

Strategic wise it would be rather stupid of Bitmain if they have something waiting to be announced since ordering process from miners starts some months ahead of release. Bitmain always puts out teasers, so frankly I think they are behind schedule on this one, or caught with trauser down…

An old article with Jihan Wu of Bitmain clearly state they are going with 16nm this year.  ==> http://bitcoinist.net/exclusive-interview-jihan-wu-bitmain-s7-block-size-debate/

Do you think you will be moving down die size in 2016 as production costs come down, and improved quality at this level happens?

"Yes, we will be moving down to a 16 nanometer die size in 2016. 16 nanometer technology has come a long way in the past year, with lower costs and better yields."

I know and have met with the people behind this project personally and they have lot of experience working with BitfFury hardware. I have strong reason to believe they will deliver what they promise.

Are they an official "partner" then, as mentioned on your website?
It would be of great help if you released a list of partners to whom interested parties could go for authentic products available to smaller users.

The year of 2016 still has a lot of time left though..  He talks about lower costs.... I'm guessing S7 likely is perfected on cost lowest amount of chips high freq.  From cost I think S7 is cheaper then a new product for them.

I could be completely off base I just see S7 as being cheap currently for them on production.  Also I'm hoping it sticks with one freq/speed on new model whenever it is S7 had to many variants.

 

Worst case scenario is bitmaintech gets a string of 1 cent contracts for power and builds a ton of cheap s-7s

as the  s-7 burning .3watts  a gh   on  a 1 cent power contract beats a bit fury burning .1watts on a gh on four cent power.

This would mean skyrocketing hashrates for all.

Best case is bitmaintech and bitfury cut a deal. 

   Maybe bitfury supplies chips to them  and hash rates do not sky rocket.
I would love to know what goes on behind the  closed doors of both companies.

Make it happen  Sidehack.. you got plenty of us that want it.

To support your efforts.

I think you missed some of the posts.  He is doing it - Community Miner Design Discussion   https://bitcointalk.org/index.php?topic=1368507.0

Kilo was great and let him post about it.  So it is a more open dev, which is always fun to watch.

I have an S5 coming.. Sidehack you can sign me up for the upgrade :)

Just picked up 2 S1's on ebay  to have them ready for this project. :)

So now I guess it's a race, Gekkoscience et al versus miner.bz?

Rocky against Drago..    :)

My BTC is on GekkoScience  ;D

May not be the earlier product, but I sincerely hope it's the better.

What day it's open to buy miner x5 ?

Very interested in this and when they will be available for purchase.. I have a couple of S3's ready for this.

- fvineyard

Don't get too excited.  ukrcoin says that they hope to have a prototype by April. 

At this stage the X5 is just an idea. Not even a prototype.

I love how some random guy can come on here and post 5 lines about some vaporware, then get endorsed by bitfury, and people like sidehack and I, which have produced miners and have the support of the community can't even get access to a datasheet to make some miners bitfury knows we can make and will sell in the thousands.

Do these companies just love promoting scammers and companies that will end up screwing over the home miners once again?

 

Even if they come out with it first and it's real, most of us in the US will wait for you, because of the support and your based in the US, that a lone makes me wait till you offer it or have it done, i even have most of the founds or will for at least two sets of boards to start .

I saw your hand populated scrypt usb flash somewhere, great job populating them by hand.
BUT Bitfury is a million corporation now with some VC funding , so they have to make money.
If this company have cash in terms of M of USD they will get info and support and chip supply before us .
I was part of a design team for a few projects and the feeling when you make it work for the first time is great .
May be there will be chance for this a few more times , may be not.
The romantic times of the Bitcoin ASIC miners are far behind.
There is still room for small developers , but we are not going to bring big cash flow , so we are behind in the priorities

Well if these guys have millions to spend you'd figure they have a least one marketing guy to write up a post longer than 5 lines...and maybe figure out how to put up a legit looking website...

Do not get me wrong .
I do not vouch for this company and my personal opinion is that this is a vaporware too.
Just saying that it is not impossible when you have good amount of cash

Yes, if we can upgrade S5's I'll hang on to mine a while longer. If you need a tester, Sidehack, I'm your gal.

We dont make preorders.
We are studining demand and taking proposition of project.

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

http://radikal.ru/fp/e8e8d1e0db4549ec81d0ce7b9e6c943c

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?

how much you paid for access to docs and sample ???

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

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.

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.

I'm not an engineer
For more technical detail information ask on the site http://en.hotmine.io

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

Yes it is

Yes it is what?
All antminer frames are supported?

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.

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

http://en.hotmine.io/

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.

I edited my post to reflect my bitfury purchases.  I would also tell the company that avalon6's work.  I purchased 3 on feb 22nd for 3.6 btc about  600 usd each.

so 1800 for 9500th  and 200 for psu's = 2000 or 2100 for 9500th  and I am mining as I type.

here is link  for the 3 avalon6's https://bitcointalk.org/index.php?topic=1371807.0


The sad part is I want the bitfury gear.  But not on a six month preorder at a crazy high price with a ½ ing in between now and delivery time.

You are not exactly right.
I do not know the details, but most probably the chips order from bit fury would take 2-3 months.
The risk that this integrator takes is big and they are trying to secure sales .
The thing is that the pre order market is over long ago back in 2013-14 and only integrator with good own or investors money can do the game

I think that is the exact reason why Bitfury asks for 1M - you, me and many others are capable of designing a miner (hell i even have the schematic ready and just waiting for the proper 250nm pinout and chips footprints to make the PCB) , but can't produce it in volume without preorders, because i don't have the funds for that.
Once the info and chips are available i will definitely make a miner for myself or maybe even few more for friends that know me and are ready to risk their money and wait (if some parts are delayed), but few will cost more per miner than in volume and a paying customer would demand to get in time what he paid for.
Advertising September is a good way to secure that you will deliver in-time and "Hot-water boiler" is not a miner and targeting different market, that needs hot water, not BTC

Not sure why we are even supporting this when we have two reputable members, sidehack and kilo, putting together there own project that is made for the community. This is another scam that popped up almost immediately after sidehack/kilo posted their plans.

can we lock this post? They can't even answers questions and direct them to the website. Everyone is answering questions using speculative responses.

Didn't someone from Bitfury back up their claim a bit? And wasn't this actually posted a couple days before kilo publicly announced the plans for a bitfury-based S1 swap? I'm not saying it's not a scam, just make sure your evidence is valid if you're going to say it is.

yes bitfury backed them up. 

I do not think they are a scam.

But the linked website is for a sept preorder.

 that is a long way off  with a ½ ing inbetween.

I would love to buy the boiler for hot water on the link, but 6400 up front and wait until sept is simply not for me.

On February 13th you mentioned that Bitfury liked your ideas using the chip under this thread https://bitcointalk.org/index.php?topic=1354434.20 . This post started February 17th, just seemed a bit suspicious to me. Didn't mean to jump to conclusions but when questions are asked they are not answered but directed to the website.

Reading the above posts it seems Bitfury did acknowledge this is a valid miner but as Philip asked and stated many times (never was answered and one member telling him to "STFU"), the preorder is too far out for that price. Just don't want members paying for a preorder and never receiving the products like we have seen so many times especially with individuals that don't have any past or present reputation on these forums.

That's fair. I had forgotten about the mention in the other thread.

My understanding is the  Antminer S5 upgrade be available in May. I just got a PM from the OP confirming this.

I think it's the various Boiler products which won't be available until September. I agree that may be a bit late. However, some people may see it as good way to have hot water or heat their house while earning some Bitcoin. I guess time will tell.

And US is like a war Empire that helped Putin to start war here in Ukraine. So what?


Well it is clearly NOT  a scam.

https://news.bitcoin.com/ukraine-hotmine-smart-bitcoin-miner/ (https://news.bitcoin.com/ukraine-hotmine-smart-bitcoin-miner/)

You guys should check the facts. Only because some companies like Bitmain are holding the delivery or not returning payments you cant claim EVERY company is a scam. Especially when this company is from Ukraine. We have a war in Ukraine going so sorry no time for inventing Bitcoin scam empires.

Riggghhtt  :D

Gotta be legit,noobie says so  ;D

Look how many articles I have translated and wrote for Russian-speaking community.

http://bitnovosti.com/author/captainplatinumbeard/ (http://bitnovosti.com/author/captainplatinumbeard/)

Do you really think Im a newbie in Bitcoin just because of some stupid member ratings on this particular forum?

Without any other references than the member rating on this forum, yes this forum will assume you're a noob.

Tell ya what,you go & video this device working (& a realtime instance of the miner software being used) & in the video hold a newspaper with the date clearly visible & a personal message to me on a separate piece of paper (I'll PM you what to write on it),then MAYBE I'll believe this device exists.

That still won't prove this device is going into full production though & all preorders will be fulfilled........................

We have a war in Ukraine going so sorry no time for inventing Bitcoin scam empires.

you really can't blame them for saying your place is the scam capital of the world , IVE had some dealing selling stuff there i trusted the buyer and ended up paying the CC company,the CC he used was stolen and  because i did not do the sell the right way i ended up paying for it . that was a few years ago .

OK. Buddha smile.


Hi man, sorry to hear that, but basically any country is a scam capital. Just look at USA and its Ben Bernanke Show.

I suspected that financial system is not real when I was 15. My parents STILL believe they use ''real money''. Ben did his homework good (or my parents just too stupid).



If I will send you the video with a paper and any text you'll ask to write, will you order one?

The problem is not that you will deliver the gear.
Not that the gear works.
Not that the gear works at 3300 watts for 32 th.

Not that the gear comes on time.

Let's pretend all of the above happens.

It means I have to wait until sept 15 or or sept 25.

So I send you 6400 used or 16 btc. And I wait not 1 not 2 or 3 or even 4 months I wait 6 months.

I can buy 9 s-7s with psus for 6400 and have them in six days.

That is 40th in six days or 32th in six months.

So the better chip is a six month wait.

The lesser chip comes in 2-3 months.  So I get a boiler in June .

I believe in your product and I believe it will ship.

But the deal on the money end does not seem good due to the long wait.

Hm. Im not a good technologist so I wont speak for the guy who is responsible for such calculations. I'll consult him and write you the answer. ok?

The "proof" is not for me,it's for the "preorder" folks/public.Post the vid on youtube so all can see  ;)

Phil is spot on also  8)

I am not mining BTC anymore,home mining BTC is dead.BTC has been taken over by "mining corporations",so in my eyes it's done  :(

Just a matter of time before the "mining corporations" really screw it up by doing something detrimental to it...if they haven't already.

Buying BTC from an exchange,you need a bank account,I have none. Buying BTC from Localbitcoins is way over priced,mining was the best way of getting them......& it's not viable anymore.

Let me pile on.

All of the above plus:

1) A bad quirk in the design.

2) Uneven manufacturing quality.

Both 1) and 2) showed up in BITMAIN's S7 and they are "experienced" in this line of work. This is devastating to the ROI of a small miner.

3) Suppose something bizarre happens in the intervening 6 months to bitcoin such that it makes no sense in investing in miners?

4) Suppose your company goes out of business in 6 months?

You haven't made a good case for the customer to assume a ton of risk. Especially since you will no doubt be a late comer to the market.

How about gettin yourself a work in Bitcoin ecosystem? It's pretty good as for me.

Like how?? I don't do "referrals" for non-existant miners or whore my self to sig & avatar leasing.

I'm not a software guy & everyone is a hardware expert,so too much competition there  ::)

Don't have enough to "invest" in any hardware development,not worth it anyhow with the corporate miners taking over the BTC network completely..........

What does that leave?? Liars & scammin?? Learned my lesson very young about that crap,I can never get away with it,like most can (BFL,AMT,BlackArrow,Bitmine,etc...)  :D

yea like others i would buy it only if it's real and selling and from were I live for that much and pay cash with  some kind of dispute protection, and you can call us what you want, I have yet to be ripped off on a sell i did in the US for money or bitcoins I'll be 60 July this year, some close calls or seemed that way, and i know it can happen at any time, no mater what i do ,but there is lot of honestly in the US or a hell of a lot more then people think.

BFL & BlackArrow here :( 

I got my BFL gear but VERY late(over a year on the 65nm stuff) & BlackArrow I got lucky as hell,had chatted with Matt alot during the Drillbit fiasco & did me a solid & refunded my BTC,that one was close.

I was too broke to go in on anything else,which as it turned out was a blessing in disguise  ;D

I almost got burned by BFL, but not nearly as bad as some. I put down on a Jalapeno in May, in September managed to get a refund from PayPal and immediately put it into an AM Blade which I had inside a few days. The only thing I've really gotten screwed on was Minion miners. I ordered a couple X1 from Minersource in about February; in July Carson talked to me about the Technobit Minion boards and I traded my X1 orders for a pair of boards from him - he was supposed to get about half a dozen of their first working boards, to back them up about all the order trading they were doing. Well that fizzled out, I never saw the boards, two of my hosting customers never saw their 40 boards, some of my PSU customers never saw their boards either, Minersource was talking to me about a big PSU rework job but stopped answering emails as soon as I asked him to get squared up about that year-old unfulfilled Blackarrow order turned Technobit order. So the only folks I've been screwed by were an American, and American partnering with some Chinese, and an American partnering with some Bulgarian. Carson did me a couple favors (like giving me a discount on an A1 Dragon with a dead board) but usually at a price (like waiting six months to ship a replacement A1 Dragon board) and it was him bailing on that PSU job, where I was already buying materials for it and was counting on the revenue from it to finish paying for my hosting expansion and had already promised my customers reduced rates, which hurt my business more than any three other bad things that have happened.

So, there are definitely Americans more than willing to hose a person. And now I think about it, both BFL and Minersource were from my home state of Missouri so that doesn't speak very well for us now does it.

Looks like an interesting project if it comes to fruition, posting here to subscribe to thread.  Hopefully we'll see a working prototype.

I didn't say it doesn't happen here it does it happens any place in the world, i don't think there is one place on earth it doesn't . my point was i would buy from American's before i would any one any other places but thieves are everywhere and the US has very tough laws for fraud then what they were when the BFL junk happen if you pay with cash, in some caes psay with btc like the BFL miss hap. it won't mater what the product is cash is cash , that's why i try to pay with cash and will use escrow for btc, if i have to don't want to and ty to avoid using escrow.

 why I  said with some kind of dispute protection , i don't trust anyone that much with large a mounts of cash involved.

DR fudge bills, dentist imo are the worst ones to go to they have no real laws they have to follow for fees like regular DR have to . don't get going with dentist ive only meet two my whole life i would  or would have recommended  to any one, one is dead he died 10 years ago the other one retied a few years ago, she was real good, i have yet to meet one sense that wasn't worried more about his or her packet even with insurance.

etc etc

but i stand by

Id only buy here cost is lower in most cases most will honor what they sell you. by not ripped off i got the product or what i paid for, if it worked right or not, completely different mater ( if it didn't i got refund and sent it back) . by close calls i had to dispute it because it takes to long but i got it , in fact right now i have something i had to dispute, should be here tomorrow or Saturday.
 post office said they had a delay in shipping it .

but for me to buy this with blind trust with no way of getting it or way to fight it i wouldn't, even if i could afford one, to be honest, I don't believe it's real or will happen, time will tell.

I hope no ones bought in to it yet. we should just wait for bitury to make it official, but that's me .

Side I in deed hope you get chips i should have enough btc saved up to get one for a c1 upgrade or 12 to 14 th . and when i get more hope you still have the chips and selling them.

cya

I agree 100%.

Lot of good info and hopefully this will be on track :

Looking forward to hearing how this goes. Posting to subscribe

And the procet what day it's ok

I wonder what happened

Has anyone ordered anything from miner.bz? I've read the thread and understand the concerns. But it's the site a scam?

Are the specifications correct on this?
I didn't think that the S5 miningcomputers could handle more than around 1.2TH for that miner.

seems quiet here.

@ukrcoin
Did you get any Bitfury chips yet?

I don't think anyone did.

Gee, what ever happened to "miners in May"?

No no no,that was "May have miners"  :D

Hey, any news here?

I haven't used anything realted BitFury so I have some questions and will be glad if anyone answers me.
Can we upgrade antminer s9 boards with  BitFury chips? Or only antminer s5 as writed in this thread? Has anyone ordered BitFury chips from seller from this thread? I understand if I'll change board than there won't be warranty but if I buy BitFury chips, will it have warranty? Also can I buy this chips from Official Bitfury?

Don't worry,Bitfury will keep their chips as long as possible to keep us home miner suckers from competing with them  ::)

And no,you cannot use Bitfury chips with ANY other existing miners.When Bitmain is done selling you home miner guys their miners,home miners are done  :(

I doubt sidehack will get any chips any time soon,unfortunately.So Bitmain is you only hope,much like old Obi Wan was  :D

 No, the OP was proposing to design an entire board sized to fit in existing S5 miners (using the frame and fan, possibly the heatsinks, and perhaps the microcontroller).
 You can NOT just put Bitfury chips into anything else, they're not compatable that way at all.

 I'm sure if you wave $1 million under Bitfury's nose, they'll be glad to sell you chips.

Some news for you guys.  ;)

The page is down  :-\
Can you quote or tell us the news?  :)

It's up for me now. Seems like it's in russian, so I can't read it, though. I'll run it through google translate and see how much of it I can comprehend afterwards :)



Edit

From what I can see, it's modified S5 firmware on standard beaglebone, with a marker for efficiency and hashrate. Looks like 0.09J/GH at 3300 GHS or so, not terrible for a simple upgrade, to say the least. :) I can't read all of it, but from the pictures, it looks like prototypes are at least working now. S5 chassis isn't the most durable thing imo, but any progress is welcome.

Yeah it worked now and I was able to look into this.
I contacted Hotmine and I try to create an order for 1x "X6 Miner", let's see what they say.
I would be happy to have a reliable European miner and support an European business.

More 26-chip unregulated strings, same as the other thread.

or even one the Us i  know side is tiring he will be it if it happen but it would be nice in the US .

Yep, working on mine right now. I didn't really glean anything from the text since I can't read Russian, but there was some valuable data in the pictures. I now have a better idea of the performance points of the Bitfury chip, since I haven't been able to test hardware yet. One of the drawbacks to being a solo operation, with product manufacture and maintaining a 100KW data center on top of design work, is that design can't always get done quickly.

Google translate link for it https://translate.google.com/translate?sl=auto&tl=en&js=y&prev=_t&hl=en&ie=UTF-8&u=https%3A%2F%2Fforum.bits.media%2Findex.php%3F%2Ftopic%2F30990-nabory-dlia-apgreida-antminer-s5-na-chipakh-bitfury%2F&edit-text=

And damn fine point the article makes about PCIe connector ratings AND lifespan. All connectors have a rated mating-cycle lifespan. For most it is surprisingly few. Each you plug/unplug some of the plating and spring tension is lost increasing resistance.

Point is connector ratings are based on being mated/unmated anywhere from just 1 to perhaps a dozen times. In the X5 link his solution is to tighten the female sockets EACH time before plugging in. Not bad but still not final solution which is to lower the max current per-pin. And um, even better, perhaps use silver flashed pins?

edit: Also interesting in that it looks like they got it to work with the Bitmain GUI  :o So both share the same API's I take it? There has to be some driver translation somewhere...

It's not bitmain gui, it's some open source modified router firmware. And API is likely cgminer's in both cases

PS: let the (price) war begin!

Sorry, I forgot that bits.media has some trouble now related to moving from one hosting provider to another. Temporary solution is to add the following to your "hosts" file (if you are under Windows):

I got to read it.  thanks


1 fast question.

can you down clock and or under volt to get lower then .099  or .101   watts a gh?

Say  2500 hash and 46 freq setting    at .090  or .088 watts?

According to this video https://www.youtube.com/watch?v=3zPpj1JYw38 (https://www.youtube.com/watch?v=3zPpj1JYw38) one can go down to below 0.07 W per GH which for 52 chips and 40GH per chip is ~2TH

Then the next one https://www.youtube.com/watch?v=zZPum2zqGPE (https://www.youtube.com/watch?v=zZPum2zqGPE) shows that at 75GH per chip it is 0.086W per GH or 3.9TH with 52 chips

As you can see X6 is advertised as 3.3TH and 0.1W/GH or ~18% increase, so 2.5TH at 0.09 W seems possible


The new (28nm and 16nm) chips do not have the current mirror circuit as the 55nm ones. My guess is that Bitfury went with builtin diodes protection only, which proved to be good enough with the 55nm

Actually what I was getting at is, no intrinsic voltage control and a nominal core of 0.45V unless you can adjust at the PSU. So, like the S5, Avalon6 and 162-chip S7, undervolting is difficult and not an inherent feature.

These are not for sale anywhere yet?

Maybe PayPal would protect us if they never shipped?

Newbie here who buys 28NM equipment off seattles CL and ships it to Detroit

Thanks all for continued support

Still not available ? Any date ?  ;D

one month

Be patient, all technology takes time, and it's likely this is only a prototype and orders will take much more time to get filled. It should launch in a month. I'm really excited some other company that's not Avalon or Bitmain is making miners :)
