Used for ~2 months at ~75% load running Antminers.

Where are you shipping from?

Denver, CO

Do you have any pictures of the actual board(s)?

How many can be chained together in an SPI chain? You say that any standard ATX PSU can be used, so does that mean they have PCIE power connectors or you have 6pin to barrel/12v adapters?

http://minersource.net/collections/frontpage/products/15x-bitfury-30-40gh-asic-miners-500-600gh-total

You can chain up to 6 together is 1 chain, each controller can power up to 24 boards total.
I have both the Green 4 pin power connectors, and PCIE>barrel adapters

Price drop to $75/board

Cool. How much would shipping to mainland EU be?

Price drop to $60/board.

Can you make a better price for 20 or more boards?

Your board look like this?

Be careful with bobsaq3

2.2 btc for 20 boards, does it include pi with controller and shipping to eu?

So if 6 run in 1 SPI chain, can you run 6 of them with just a raspberry pi and no black arrow controller? Or is that controller needed for any setup? Also, power connectors. Do you include PCI-E to (multiple) barrel connector cables? If so, how many boards would 1 PCI-E plug power?

Yup thats exactly it.


Does  not include shipping, includes controller + pi


YOu need the pi and controller regardless of number. We will include the power connector for up to 3 boards per PCIE as long as your order 3 boards.

hey bob with the "g", lol

can you post more pics ? maybe some screenshot while hashing ??? the pic posted here & BA link is different : dual fan vs 1 single bigger fan.

60USD/36gh/s (according to BA site) - approx. 1.67 usd per gh & there is a little note on the site (this is a used product) so is this batch new or used ?

a little details also pls, "up to 40gh/s" so what is the minimum @ stock settings i'd assume min is 30 gh/s ?

seems like it's a little over 1W/gh (stock no OC) if i'm not mistaken.

any warranty ?

what rate are you using if paid using btc ? accept paypal,credit card ?

OP says includes shipping, what kind of shipping ? dhl/fedex,etc ?

not trolling just want more info before i make up my mind to make a purchase.

thx.

I can get plenty of pics tomorrow.
These are the dual fan V1 boards.
Used (old batch) boards.
They average out to 36-37gh overall, some do 39-40, some do 34-35.
They use just about 1w/gh at the wall
7 Day DOA warranty
Coinbase Rate, I can take CC/Paypal at a pretty high (~10%) fee. Otherwise Wire/Cash Deposit into Wells fargo/Money Order
We ship UPS/USPS exclusively

Let me know if you have any other questions.

By controller you are referring to the raspberry pi. So to power the whole setup one would need 16 Pi units. Now, do these boards have some usb breakout connector or do they interface with the Pi only via the SPI connector. The issue is that since you have 6 per chain how do you tie together 4 chains together to be controlled by the Pi's single SPI connector?

No. You need both a Pi and A Controller, and a single Pi+controller combo can power ~20-24 boards. 4 stacks of 6

pm'ed. thx for the speedy reply ;)

Ok, gotcha. Thanks for clearing that up for me.

Im confused, whats their stock rated speed  / power consumption?
Whats their OC potential / power consumption?

They are rated at 38-40gh stock / 40w of consumption. Bad BF chips however result in anywhere between 34-40gh per board. I do not know if you can OC higher than this, have not tried.

Buying a set from Bobsag3; reserving this post for the proof of transaction.

Update 05/13/2014:
Issue resolved; thanks Bob for following through on support !

Got any pics of these all chained together?

Edit: Nevermind. Found one on the BA website. I don't know if I can deal with another Gridseed like mess of wires.

Can ya link? Im considering buying some. Wanna see how messy it is. Also, whats the reliability of such a setup?
They as stable as ant s1's?

Can I purchase the 17board kit from your website and pay you with bitcoin?

Thanks!

Edit: Just purchased a 17 board kit from http://minersource.net/ (http://minersource.net/)

Hope to receive it soon!

Yup- you can checkout using bitpay. And we keep 100% of BTC funds :)

Bump

To the top!

Still available.

I think we need another price update. Just PM me if you can.

Price dropped to $50 / board. Any previous customer who bought at a higher price (65 or 100) can get them for $40.

can someone post the pi image they are using for this? tried the black arrow one but reports error with mining_proxy and still doesnt work after updating it.

You can use any pi image with the newest version of CGMiner, kano added code for these a while back.

any idea on configs? running cgminer latest version i get

BaB0: Delay getting work reply...

I get that too.  Very little documentation on that. ???

would be very interested if you can solve it, otherwise will have to try again with chainminer....

interesting - your deal is $1/gh

and if I bought $1,000 that's 25 of your boards = 1,000 gh

and that's 1125 watts

and with electric it's $21.47 net to me per day

hmmmm.


I already have a pi and psu's from my mining rigs which I'm replacing with scrypt asics...

I may take you up on your offer.

I made a support thread / setup guide for the black arrow bitfury 16 chip board. I'll post my cgminer setup guide later. Here's the thread:

https://bitcointalk.org/index.php?topic=615118.

Whats the lowest you can go for these?

$40/board

thanks, looks like it was more my wiring than software.

bump

If I purchased a kit (I did) from Minersource, can I buy more boards at the $40 price point?  Also, do these boards have a tendency

to produce many errors when connected in larger numbers.  I can get sub 1% out of EACH board separately, using Cgminer, but

more that 10 connected at once gives me crazy errors.  Even if I knock the speed down to 50!  I would like to connect 24 boards

to one R-pi/controller. 

Thanks!

Have you overclocked ? i want to know how or a guide to that


also i would love to buy 18 boards from this group buy i want to know if i will get the r-pi and the controller if i did

We do see a tendency for a smaller number of errors, but not significantly. You may have a bad board in the stack that is effecting the others. You can buy as many of the boards @ $40 as you would like.


No overclocking, but as long as you buy > 13 boards, pi and controller are included.

if these were $30/each it would be a non decision but with the price of the big rigs dropping so fast it's just easier to wait and not have to 'cobble' a 1 or 2 ths system.

there is a guy pretending to be you
https://bitcointalk.org/index.php?action=profile;u=327218
hes trying to scam people
i will buy them ill PM you about it now
also if anyone could tell me how to overclock them it would be great

q instead of g

scumbag!

Thats fup

Bump.

Alright, also he is in the USA... damn, shipping those things to Europe should be a pain.

bobsaq3 have you considered hosting?

We dont have any more space, kinda why we are selling them :(

I also have EVGA 1300W G2 psus for anyone that wishes to purchase one to power their boards, $140 ea if you buy it with boards, $150+ shipping otherwise.

sent you a PM.

Get back at me. 

I sent you a PM. Please respond when you have time. Thanks.

Someone is up to old tricks.

https://i.imgur.com/V3CVdrV.jpg

Damn scammer, Bobsaq3. Reported to mods.

Please leave negative trust feedback for this jackass.

Thanks for catching it. If the Pm doesnt have "yall" in it, odds are its not me!

How loud are the fans on the boards compared to antminer's ???

Quiet.

Cool man , How many boards can you stack together and mine , with a single controller?

24 per controller, 6 x 4 banks.

Best price you can do on 40 - 50 of them with all accesories to plug & play

Payment sent for 72 boards.  Now, I just need someone to come and set them up..any takers.

We are out of the controllers and Copper bars, so I am reducing the price to $30 a board. Controllers can be purchased from in-stock form Black Arrow:
http://www.blackarrowsoftware.com/store/bitfury-controller-version-2.html

The Bars are simply extended length motherboard standoffs. We still have plenty of the cables and power cables.

how many left? will u restock the bars + controller? will prefer to buy them as a complete set n start hashing away.

please reply to my pm, as im still waiting on boards i may buy a few more for this price.

mind to share some pix of your setup + a mini guide or tips ?

TIA

this is the best thread for tips and a guide on these, awaiting op to post pics of the capacitor grounding.

https://bitcointalk.org/index.php?topic=615118

Have about 75 left or so. Will not be restocking the controller or bars for such a low number.

Customer's Outgoing order of 100:
https://i.imgur.com/3YoCDL9.jpg

I am not onsite where my boards are. Does anyone know the length of the brass bars included with these?  I guess about 20-24mm.

Are they sold out now? i just got my bitcoins and was going to buy and they are off the website

they are 30mm

We dont have any controllers or Pis left, so we removed them from the site.

Bobsag3's crew at minersource is super fast. I sent my payment this morning and they where packing my order when I called to make sure the transfer had been done. Great customer service. I can't wait to get my boards.

I'd like to order 3 of these bitfury boards. Do I order them through the website or just PM you my info?

PM

Anyone have a source for the standoffs? My boards did not come with any.

http://www.aliexpress.com/item/Single-head-hex-standoffs-M3-60-6-a-pack-of-50-brass-screws-monitoring-security-isolation/1722692463.html

And they are all sold! Will leave this open for feedback for a week or so.

Could you please answer on my PM`s 

Since i payed yesterday you stopped to answer me

I see I'm not the only one having this issue. I paid on Tuesday night for 3 and haven't heard a thing from him. I've sent him a few PM's including one about 30 or 40 minutes ago when he was online. And now he's offline.

I think Braindead and myself would like to know the status of our orders...

He is online now... seems he doesn´t want to answer our pm´s

This is really fishy, hope we won´t be scammed, i asked for escrow he told me he wouldn´t do escrow because he is a trustful member etc etc with a company etc

Chill out guys, I got all mine just fine with no escrow and I know others have as well.

Try emailing support@minersource.net. I am not defending bobsag3, but he is currently in the middle of cleaning up black arrows mess. I don't think he is going to scam you over some bitfury boards.

I got all 75, but when I ask questions, he doesn't respond to em, even though I see him online. Like I ask do you have the PCI-E to barrel connector in stock.
And he doesn't answer my PM at all, no message, no info, not to even say nope we have no stock or any information. Like I don't exist.

Seems anyways, I will have to build the cables myself from scratch, using barrel connector screw in tops with pci-e wiring.
