21  Bitcoin / Hardware / Re: Black Arrow 28nm 100Ghash Bitcoin ASIC from $1.99/GH/s, miners from $2.97/GH/s on: June 25, 2014, 10:49:15 PM
tempestb I really doubt that BFL which produce the first melting PCIE board in the world can ever produce energy efficient HW.

Speaking about X1 ; david said that heatsink is not so hot at the touch, and all people read the internal chip temperature near 80°C. Heatsink with heatpipes should be very efficient to transfer heat, so deltaT between chip & exaust air shoul be very low. Is termal paste applied correctly???

Reading Bob's mesures what I think is this:

1 - More than 120Gh @ under 120W is good, cause freq can be adjust between 1200 Mhz and 800 Mhz, it seems like BA choose to deliver all hardware OC by default (correct me if I worng).

2 - If we get less than 1 W/Gh in max freq state, there must be room to improve it in lower speed states, but doing it for the moment dosen't seems to increase efficiency significantly.

3 - Possible cause. Chip + power regulators have better dynamic power dissipation than static power dissipation which is good, and this could be why errors increase lowering frequency ( makeing this, chip is forced to pass more time where it dosen't like - especially if it is hot )

Fixes - try anything possible to cool more chip ( this will be good for efficiency & stability at any state ).
        - control voltages (Bob said on ecoin that this will be possible, I suggest david to write this in firsts order on the work to do list for programmers, cause achieving for example 0,7 W/Gh will seriously impove BA situation ).

Bob (or anyone else) , is there any drop in temperatures when you run @ 1000Mhz or lower Huh


I dont think the software based temp sensors, or their software is not working. Our X1s report either 0, 60 or 80c, nothing else.

Clocking to 800mhz only drops the speed, does not seem to impact power consumption all that much. Seems the sweet spot is 1000-1100mhz.

I didn't said sw is not working, only suggest BA implement voltage controls as fast as they can (I see temperatures only HW related)  Wink .  The fact that 800Mhz drops only speed, fully support my thesis. Grin
Would be a shame we can't acieve the better energy consumption only for those little details  Roll Eyes

Sry ninjaboon but I see this as a general X1 topic and I don't want to make bob and david start to loose time jumping along btctalk. Those detalis could be usefull of every X1 future older too.  Smiley

The chip can still be tuned and tweaked. The thermal paste is applied properly and does its job well. While I was working on my X-1 I got it running but forgot I didn't have the fan on it. The heatsink and thermal paste work very well Smiley.

Ok, I needed to ask though. Can you please send me a pm with your order details?
23  Bitcoin / Hardware / Re: BA X-1 Unboxing on: June 25, 2014, 01:45:03 PM
Hook up a monitor on the rPi HDMI interface and look what it is doing. is it even booting ?
iff not you got a corrupt file system

it is not the rPi. I'm not sure what kind of I/O the custom controller all has.

Are you sure the subnet on your modem is set to the correct IP range (192.168.0.1)?
25  Bitcoin / Hardware / Re: BA X-1 Unboxing on: June 25, 2014, 01:22:41 PM
Ok that is the custom controller version. I do not have one yet myself so I'm not 100% up to date with bugs on it. Can you tell me which LED's from the last 3 pictures do light up for you, as those will be the same.

When it is first turned on I get these 2 blue lights and a red blinking one n the custom controller, the red blinking one goes off after about 20 seconds and this is what I'm left with:

and chuck thanks for reposting the pics.



Please send me a PM with teamviewer details so I can look at what the software is doing.

Having been away from these forums for some time now planning my wedding for this August. Can anyone catch me up and summarise any important info that may have been posted? I have been seeing minersource on facebook.

Just curious about delivery times, if anyone in the Uk has got theirs? Compensation? What about customs values etc? Anything worth knowing?

Thanks

This should help: http://ecointalk.net/topic/603-weekly-production-update/.
Along with minersource has received the first shipment of X-1's.

The netmask needs to be 192.168.0.x or the miner will not be found. There are a few things that could be happening. You can send me a message here, or preferably on ecointalk (interface is easier and faster to work with for me) and we'll get this sorted for you.

I'll post some pictures of the LED's and what they mean.

Under 1w/gh. Not bad. Not bad at all!

Actually, it's quite horrible. It's not even close to what was promised.

Prospero X-1 will scan 100Ghash while using less than 55 Watts and Prospero X-3 will be able to scan an outstanding 2000Ghash while using less than 1050 Watt.


That was our first design before the delay. This design was expected at 0.75Watt/Ghash. The chip can still be fine tuned to get a better efficiency.

Damn,you must live next door,I thought the just got them a few hours ago! They didn't give you a power cord at all?

Our first units did not include any power cables, we will be ordering enough spare cables at least for all our US customers. Several people did local pickups today, hence them having them so fast.

So have you tested any units if you don't have power cables, I assume you tested a few, but not in bulk? How long will it be to get the cables and will our orders be put on hold until those come in?  can we request the units be sent without cables and we can source our own or pay for shipping for those separately?

You can buy the power cables at Frys or microcenter or steal them from a laptop, etc. They are standard Mickey Mouse cables. C13 would have been better though.

Yeah power cables are a dime a dozen, but it's really weird that they wouldnt include them.

Power cords will be included. These initial boxes didn't have room for the cords so they are shipped separately. The new boxes have room for the power cords.

They are selling PSUs for compensation units that are very unlikely to ever arrive. The X3s themselves do not currently exist. I believe the continued lies from BA and pushing back delivery of compensation units to an undisclosed date demonstrate this. You are welcome to disagree. I only posted information of how to contact Bitpay. I did not tell anyone to do so unless they believe they were scammed as well. If everyone agrees with you, then minersource has nothing to worry about.

A quick update for anyone having problems with a BTC refund from minersource or another merchant who uses Bitpay. Here is the response I received from Bitpay,
"I have noted a complaint from you against the merchant. If a sufficient amount of complains accumulate, then we will take action on the merchant's account."
You can call Bitpay at (855) 424-8729 to leave a message if you would like to file a complaint. Make sure to leave your email address and they will contact you by email.
why are you being a fucking child who won't stop throwing a tantrum? Seriously do you want Minersource to not be able to accept bitcoins because you're a child?

+1

Minersource has never scammed anyone.


X-3 doesn't exist? Since the backplane issue has been fixed I would consider it to exist.

@david I think everyone in this forum would appreciate it if Blackarrow and company come in here and take into consideration  customers' input in regards to the final compensation for batch 1 before making a final decision by themselves.

David, please acknowledge this. Awaiting your response..

Any input on the compensation can be posted here or on ecointalk or PM'ed to me. I am faster at answering on ecointalk usually because the interface for unread posts and messages is better


X3 progression ?!

They need to come up with the next stall tactic on the X3.

They did a stellar job on the X1, where magically the original controller started working the moment people started asking about the rpi version shipping.

The controller didn't magically start working, the problem with the control board was fixed by the engineers.


After being flamed at on the ecointalk forums for asking this very question, I contacted MinerSource and they stated that they will not know what cords will come with your unit until it arrives at their facility.  They will then notify people on whether they need to buy cords or not.

Per ecointalk forums, David said they would do their best to ensure everyone has the correct cord, this was also stated previously in updates.  But, the first actual miner, received by MinerSource, did not come with a power cord per Thomas_s, and the first miner, not to a BA employee or reseller, came with the wrong cord (per ecointalk forums).  Obviously we know what BA's best is given our current situation, but I think given proper notice from MinerSource I can still order cables and have them arrive in time with my units so I cam holding out for that.  (although I would be very unhappy to have to lay down another 10 or so dollars per X-1 along with shipping costs)

Just for your information, the unit shipped to me had the correct power cord.

I would like to remind everybody that sending this type of information to a person you do not personally know and trust is an extreme security risk. We highly recommend to not send this type of information. Again if customers want to work together or help each other that is no problem, whatever the subject matter.

My previous post which didn't make it to be posted asked a few simple questions which I guess were a bit too hard for BA. One request was that anyone that does not have any affiliation with BA or any of the resellers please post pics of a working unti. I also stated that I will gladly do the same.
Lets see if this post gets to be seen.

Please look here: http://ecointalk.net/user/1398-mininuke/

My PSU and miner have just been delivered. Going to start remote setup now.


37  Bitcoin / Hardware / Re: Black Arrow 28nm 100Ghash Bitcoin ASIC from $1.99/GH/s, miners from $2.97/GH/s on: June 10, 2014, 12:15:54 PM
Now that there is some actual pics of an X1 running, albeit for less than a few minutes, im actually thinking that I might actually receive my units, woohoo!!  even though its a few months late.
The working unit looks nice and easy to manage and power so I personally cant wait to receive them and see how they go.
If Bobsag, being the only person in the world who has a working unit apparently, could possibly post a pic showing that the unit has mined for over an hour consistently, then this would show us people who still get some form of assurance from screenshots etc, that what we will/might receive soon is going to be worth the wait.
Cheers from OZ.

My unit and PSU is out for delivery now. As soon as I can set it up remotely I will take some screenshots, maybe screen video if that works.

You can be angry and say basically whatever you like. However we don't like people who are rude and abusive.

There is nothing that any irate customer could possibly say to you that is more rude and abusive than Black Arrow's conduct and performance. Case in point, this completely insane article making incredible claims about future product lines, when Black Arrow isn't even capable of ironing out the most entry level serial communications systems that even an intelligent hobbyist can do. There is literally no actual shipment-ready product confirmed in the 28nm line (other than purchasing the ASIC chips themselves at reduced prices now that indicate some kind of quick liquidation) , yet somehow it's acceptable for the company to talk like this to the press and general public:

http://bitcoinexaminer.org/alex-berk-black-arrow-as-soon-as-14nm-is-available-well-release-a-new-asic-that-will-outperform-any-other-14nm-designs/

Please contact me if you think you can solve the backplane problems. I will then discuss if it is possible for you to come solve it.

"Prospero X3 is a monster"

he clearly knows absolutely nothing about this industry. the next step is 16nm.
I am glad that tracyhh has gotten the police involved, it's way beyond the time this should have happened.

As for the comments regarding rude customers; it's not the place of the seller to act in such a manner. These methods are also illegal.

I'd avoid making it easy to identify who you are between your order number and you user name here. They are being vindictive about people who are anything but positive about them.

Same with BFL, I can't post anything without it being reviewed by a Moderator and nothing has managed to get through to being posted, not even a calm post so I doubt they are even looking at them so I guess I'm banned.  Funny thing is, I don't even know what I did to get banned.  No communication at all from them.

It's called 'showing professional prejudice.' David, you should know better, as a professional entity, you are not entitled to express such opinion.
bring it down.

Actually the next step is 14nm, early 2015



david105396 as you will get your miner soon I am very interested in some information.

The relationship between temperature and overclocking.
The relationship between vcore (not me lol) and overclocking.
The relationship between temperature and power consumption.

If there is enough overhead in the stock heatsink you could test it by controlling the fan manually and setting it to the maximum. If there isn't it will also be interesting.

My guesses are that overclocking will be heavily dependent on temperature a midly on voltage hitting thermal limits with slight increases on vcc while on stock cooling, I also think that it is quite likelly that there is a significant decrease in power consumtion with decreased temperatures. For those things to be really noticeable we need at least 20ºC of difference.

That information would really help us extracting the best overclocking and or getting a better hash/w. I am building a custom cooling and it would help me quite a bit.
Also, what is the maximum overclocking and voltage that the interface/hardware lets you set? (even if it will never reach it with aircooling it might with water or phase change and what could be reached could determine what kind of cooling is worth).


These are the test I also plan to perform.

Update on the shipment, for those that want it.
It has been given a release by customs in Amsterdam (both PSU and miner).

I thought you were part of the Blackarrow team??

I am currently not in China. This is a unit to be able to perform tests from where I am. I am giving the shipment updates as some have requested this with the first unit that was shipped to minersource.
