you are way behind in efficiency. 1w/GH @ 28nm ?

no thanks.

include shipping fee in price?

Interesting looking specs. When did you tape out and at what foundry? Temperature of sub 35c when operating? Do you have any video of the miners?

Edit: Missed the quantity of chips was already stated.

Does "rigorously tested and tuned at BitCrane’s testing labs" sound like "second hand" to anybody else?

What's $1580 these days? About four S3 boxes which would be nearly double that speed and nearly half the power consumption per gh?

Looks like they didn't skimp on VRM's (do I see 24 per chip?) but 500w per chip is a crap load of 0.7-0.8v to deliver:

http://www.bitcrane.com/images/detail_12.jpg


Somebody got in there quick... 1w/gh is very poor for 28nm; why is performance so poor on a brand new line of hardware?


"hash rate of 550Gh/s per chip" this answer does not require complex mathematics. But tapeout who where when, temps (with water cooling) and vid would be good.

Looks like a nicely designed unit, I like the water cooling, just a shame the hash power isn't 2TH/s.
Would still be nice to see a Dogie review of one of these?

Can we have some on hand pictures?

1)www.bitcrane.com = 404 not found

2)1 watt a gh = loser unless btc price goes up over 1200

3) what is the price?

4) facebook  address works

5) back to price if unit is in had and ships in a day or two in needs to be less then 3x s-3's   right now 3x s-3's are 3x .68 btc = 2.04 btc

that is 1155 usd.  and you need a psu the evga 1300 is 175 at amazon.

 so 1330 usd gets you 3x 425gh = 1275 gh  at 996 watts  if you run the s-3's at freq 212.5


this gear is 1100th at 1100 watts

So if the s-3 setup is 1330 usd and can arrive in the usa in a week

this must arrive in a week and be under  1330 usd to compete.


That said looks nice  I would love to have one of them.

Good luck with your new hardware announcement.


Cgminer is governed by the GPL version 3 license which means you are obliged by law to post the source to any modifications you have made to the code such as adding a driver for your hardware, so please post a link to your source code modifications. Thanks.

1. can we have video of miner working?

2. can we have price reduction since it will never ROI this way?

3. can we have power consumption lowered?


other then that, it looks like a great unit.

The case looks nice, I like the water cooling too.

What I don't like is that your site doesn't work. You should have made it ready before announcing here.
I've heard of you guys a few weeks ago, but the lack of site discouraged me.

Site works fine for me

They are using two trademarks that they don't even own.   ???

Edit: The "radiators" in the pics of the outside of the case don't look like radiators to me.   ???

same

Edit I got to it on a vm using windows
and if you do not have free power it is too expensive  1580  usd needs to be under 1200 usd including shipping

I get this for the site using safari:

I tried to reproduce your URL link findings but I didn't get a Rhino's arse nor did I get a search for putin. Am I doing something wrong?

a quick search on Google shows your business all over the place that a good thing now you showed a premium build product with water cooling, it is nice but not necessary. nice casing with power supply included.

To do list suggestion

1 chip system on open frame with fan no power supply priced at 0.6 btc and you become the "best in class"

The problem right now is you want to sell a bitcoin miner the same way computer business sell computers and that not the way to go

The nice looking stuff gamer buy it for showing off in their living room and on the net to prove they have the "best in class" computer system

IMO you have a too fancy product to compete with other miner out there

quick eye .  we all need some humor here.  that is an elephant btw.


as for putin:

https://bitcointalk.org/index.php?topic=673267.100

To be honest it looks like S2 in a different package.

Pretty thing to put on your desk, but nobody's buying these to show off.
This would be a great competition to Bitmain for the same price, as it looks better and has better cooling, but you're at least 2 months late.

You are a mac user so your opinion is invalid; but that said would this even be a wise investment based on free power? At this point you could get a shipping container full of 132nm for that price?

$1.58 per GH/s =

http://lh5.ggpht.com/-Cvrpn-GFetY/TRuOpQMIoGI/AAAAAAAFx5c/l4Vmy8aJj8c/s200/l2772.png

You gotta be around $1 per GH/s or less to compete in this market right now.

Also, your name rhymes with Bitmain, is that just a coincidence?   ::)

Lastly 2 asic chips total per miner????  1 asic chip = 550 GH/s???  Ultrahoist modules??  Never heard of those asic chips before.

You'll need to forward a review unit to a trusted member here in Bitcointalk to prove you're Fo Realz Realz, or no one will believe your outfit.

They had it been a month ago.
https://twitter.com/BitCrane/status/483448824493375488

And let's be honest. S2 is a better product. I look forward to this time, when the new S2 upgade modules will be on sale .
Miner is not a car that would require water-cooling. Water cooled miner needs always a bigger  cooling radiators and better cooling fan.

I tried that already with KNC modules and Corsair  H100 water-cooling
 Much better cooling can be combined   Artic Cooler i30 with  SilverStone FHP141 fan  http://www.silverstonetek.com/product.php?pid=366

Their closebup board shots bear many similarities to Hasfast based boards - ie: Habaneros, Yoli etc...

Combine that with liquid cooling, elongated footprint, and their hashrate/power, I'm guessing this is a Golden nonce based miner.

Looks like a motherboard and CPU to me.

Those pictures are of a HF "Yoli" board.

http://hashfast.com/wp-content/uploads/2014/02/Yoli-Evo-board_FINAL-white-WEB-e1392926017925.png

ibtl

correctly.

So they are... well I guess the hf hardware had to end up somewhere didn't it?

I would still buy it if they were proved to actually exist and the price was right!

BitCrane-Tech I will accept a unit to review and test for the forum. Following on dogie's format, but adding my own personal touch and detail. And to add, I will give you the option of me sending the unit back once I have mined enough for postage. Send me a PM and we will talk.

May be it will take less time to send it from China to me, in Novosibirsk.  ::) I can even pay for this miner with some discount after review...  ;)

BitCrane-Tech, is there at least provided a way to overclock your suggested miner? and why does your website working so confusedly? I can see a User Manual once, and can't see it after refreshing a page...

I must be missing something??  A newbie account with 2 posts, comes to hock gear which consists of zero details, just photoshops and a pseudo-attractive pricepoint - from a company no one's heard of, schilling from a pseudonymous domain hosted @ GoDaddy?  Pu-lease!  scam-alert yo!

What ever happened to the Cryonik's miner?  This reminds me of the folks that brought that concept to "market" (ie, collect funds and deliver squat).


When will folks learn that you're only scamming yourself in the long run when ya pull this kinda crap...?

You realize, of course, that Macs are practically ubiquitous with those in creative fields, right ?

Here are some of the pictures of T-110 Units in our office

Best regards to all

“BEST IN CLASS” ＝＝ 1KW/GH ?

are you using A1 Chip?

Seriously?  Did you read any of this thread?  In less than 2 pages its been established - Hashfast chips.

I want that, staying at the top...  ::)

Why not post the Eligius address so we can see the live hashrate? Or directly the miner software screen.

Not at 500GH/chip. My unit will land on Monday, along with 3 other units so I'll do my best to turn this around ASAP.

perhaps hashfast boards since they can do 400-700GH in a chip

Does your mac have 16 processor threads and 84699mb total graphics memory? I thought not. My video rendering box does.


Looks like two of the same box laying on it's side to me.

Here are some data images of a BitCrane T-110.
A review from a trusted third party will be available on the forum very soon.

BitCrane

You will need to be a lot more aggressive on your pricing strategy for these to be viable. $1580 for 1.1TH/s @ 1100W is essentially old gen hardware dressed in new clothes. The price needs to be < $1k

"Nominal Power Consumption: 1100W" for 1.1 TH/s? 2x Antminer S3 is a far better deal...

Apologies for the delays, unit will be in hand eventually, when DHL stops sleeping and actually delivers it. Its been in the local depot now since Friday afternoon...

Great that you are getting a unit, but the price is still not competitive.

Please lower the price to 1$ per GH/s..

philip why does it look like there is an extra letter at the end of that address on the mac?   www.bitcrane.com/m

I have a unit being shipped to me tomorrow. I can confirm from them that they use Hashfast's chip with their own board design.

So what do we have?
There is no User manual at their website.
"Product specifications" exists, but in Chinese.
It's an expensive device (you can buy 3 Antminer S3 for that price).
We don't know anything about overclocking possibilities of this miner.

How could you decide to buy it?

I'll be receiving a unit myself Monday-Tuesday looking forward to checking this product out!

Well that's interesting, because I'm pretty sure it's not their own board design if their advert pictures are of their actual HW.

At the time I entered the website I entered it as www.bitcrane.com    all my macs added the /m and could not link to the site.

what ever caused that has stopped.

Back to this item.  you can buy 3 hosted s-3's with a cc for 1347 usd.  get 30 days  for free then  30 days for the 3 for 81 dollars. so

lets see.  pay 1580 for about 1050gh must provide power. use btc

or pay 1347 for about 1350 gh 30 days free power.  use a cc

Thats what I was told - Ill be ripping mine open as soon as I get it

who has this deal? thanks
i see a $1500 for three with one free month, then $81/mo.
1347 is a good deal

I'm betting they used the reference design with only minor changes.

If they had used their own design, or even an improved design - then should run 1.2-1.4 TH/s not factoring cooling and power (or efficiency).

What do they do just send out random units to different people? Shit, I'm gonna start doing nice reviews with hi resolution pictures. I want some free gear.

oneminer.com offered it for 48 hours mines at gaw / zencloud   you could buy 1 or 2 or 3 some got as many as 12.

I got 1 it is mining as I type.  my cost was 449 for the one.   and I had a 20 dollar code so 429 net.
 
  deal is dead.  my point is this item on this thread is over priced at 1580 needs to be under 1300 more like 1100

Dogie's comprehensive setup guide now up in super HD! (http://goo.gl/7Owoh8)

 https://farm6.staticflickr.com/5586/14882651783_f864d37ec5_b.jpg (http://goo.gl/7Owoh8)

1W/GH shold be priced below 1$/GH.

I bought some Antminers and I got below 1$/GH, including PSUs.

Ants also have a 20% better efficiency.


Not only is BitCrane a bit late to the party, but their pricing is way off, especially considering they bought the awfully cheap hashfast chip.

Isn't the most important metric now w/GHs, more so than $/GHs? It certainly is for me! If I want to continue to earn some nice extra income, I'm going to have to replace less efficient equipment with super efficient gear. Not so much because of electricity costs but because I simply can't put another watt on my circuit breakers (nope, not interested in DC hosting).

I'm very curious to see what these other 28nm chips would do when run at more efficient clockspeeds. I consider all other 28nm chips to be absolute failures except for KNC, Spoondoolies and Bitmain (and of course Bitfury's 55nm chip).

But what if everyone wasn't pushing the GHs at the expense of efficiency. Would they be significantly more efficient or are they just shit chips?

Great point

Agree, antminers S3 are by far the best...

It really is that easy^

The build quality of this unit can not be underestimated, compared to something like a BTC Garden or the R-3, you can tell extensive work and effort went into designing and building the case and the internals. Probably one of the best built miners you can buy today, if not the best pricing.

pretty expensive tho ??? plus it seemed to make some awful noise from that vid they just posted. Miners have a short lifecycle i dont see the point in buying expensive HW that will turn useless in less than 1/2 year anyway. pretty or not. good sales pitch but i'll pass.

yeah $1580 for 1TH?  2-3 months too late IMO

ROI is infinity.

I will buy three @ $850 but they need to be delivered (East Coast USA) no later than Wed 8/20.

Not to pile on, but lketc is selling their dragonminers innosilicon theftboxes for ~$1,300k - which is still too high.


On a brighter note, it's amazing how many choices are available now for those who want to buy asic based miners. Let's just ignore the fact that most of the sellers are either selling off their old, worn out equipment or are liquidating (maybe to reinvest in newer hardware, or not).

You see, the realistic best case is that a company sells at a price where you might break even - provided that the stars align correctly - but at least now you can shop around and try to figure out which company is least likely to deliver late, deliver garbage, or not deliver at all. And then get mad when you guess wrong.

And the manufacturers laugh all the way to the bank

I will pile on. AsicMiner tube for 1.04 btc 800 gh around 800 watts  that is about 540 usd for 800 gh.  to be fair you need a psu get an evga 1300 for 180  and you have 800gh for 720usd.

or 1600gh for under 1400 since you do not need to buy 2 controllers.

http://hashfast.com/wp-content/uploads/2014/05/chip-efficiency.gif

As you can see you can go down up to 0.5J/GH. HF has tons of uncut dies still in wafer forms. It's probable that they will not package them into the power monster that the GN chip is, and run them on a more efficient setup. I for once hope so.

BitCrane T-110 EZ-Stack video is now available on our official Channel. The video shows how EASY it is to stack T-110 units together without any additional rack.

I am blown away by this. This new 'stacking' idea is the future.

The stacking is nice.

If it allowed hot aisle containment, it would be even better. (Which is where the standard rack shines)

It does make sense though. What they're saying is you don't need racks with their units - as long as you don't need access to the unit at the bottom.

As the first batch of these seem to be sold out, I can only hope future batches will be cheaper.

I also hope they will be able to continously source cheap chips from hashfast. (I see no reason this should change though)

I must say that this is the most dangerous looking miner.
Nice colors, black and yellow.
Design is good, but I will wait for the moment to add miners again.

Or they are just advertising that they are sold out to create a hype and to allow time to reconsider their pricing structure.
Watch they will come out with a new version without water cooling.

LOL they already sold out, looks like people want to get there fingures burnt buying useless hardware

I guess some individuals bought in bulk at a reasonable price.

Without significant downclocking, the density on the GN chip is too high for standard air cooling.

bitcrane does bulk orders ?

BUMP

nice price

So, is this the next hardware manufacturer that has to be forced into complying with the cgminer developers request to release their code - as stipulated by the GPLv3 License Agreement?

@ BITCRANE: Other hardware manufacturers have released their code after pressure from the Bitcoin community forced them to do so (most recently Bitmain, one of the largest). Please be gracious enough to respond to, & grant, ckolivas request - it should not be necessary for the Bitcoin community to have to force manufacturers to abide by the law. This will also alleviate any suspicions the community has about closed source software that was provided by the author for free as Open Source.

Thank you.

Well spotted  ;D

how is it scam, they have a video showing you hardware...

No, the scammer deleted the post when he got busted.

Look:   https://bitcointalk.org/index.php?action=mlist;sa=search

@bitcrane
Your link has an error in it.

Glad to see a more realistic pricing (although still quite high).

Corrected....thanks.

I'll bump this too.

BitCrane-Tech:  Please consider ckolivas's request as a matter of urgency - you are breaking the law and the GPLv3 License Agreement until you release your cgminer code as requested by the cgminer developers. Apart from this, miners are rightfully suspicious of manufacturers who refuse to release mining software that was kindly provided to them for free as Open Source - please comply with the GPLv3 License.

Thank you.

Price still impossible to ever get your money back.
Manufacturer still playing games with the software.

Anyone buying this needs their head examined.

Bitcrane, the price of this miner needs to be SUB $1k for it to even be considered.  Until then you should just mine it yourself, which I am sure you are doing anyway.

Not only manufacturers mine with your gear.
Look at mr fly from easy2mine.com
Miners at his DC are  down every day.
In the meantime his other address at www.f2pool.com has an unexplainable increase in hashrate.
Where does that hashrate coming from?
Oh, it must be variance or pool luck.

@ckolivas

Thanks for the reminder.  T-110 uses an unmodified HF's cgminer 4.3.3 and is available on github.

did the units arrived? I need to know if this company is legit.

Yeah, I know at least me dogie and maidak all got units.

This is partially my fault. As prelease setup support has got better, less and less people ever post about getting a new unit so it becomes harder for us to know when things have shipped.

great, but wished the price was lower.

I can only echo others comments, without doubt one of the best looking miners out there, but at that w/GH rate you are competing with the dragons that are $999 $829, and no amount of style is worth the extra.

In fact the new dragons are only $80 dearer, are 400GH faster and significantly better on w/GH

Check out the T-110's latest review and rating by CryptoCoinsNews (http://www.cryptocoinsnews.com) :

Eight seconds is how long ago the last share was received by BTCGuild.

Thank you very much for that information. In that case can I implore you upgrade to the latest cgminer code for there are numerous stability and more importantly security fixes that went in after that version. 4.5.0 is a very stable code base to update to.

This company is now the latest in a series of unexpected yet welcome turnarounds who have sent me one of their 110S miners to help maintain the driver for them, although I do not believe they are selling them any more (they're not competitive anyway). While I'm not sure whether their next offering will be aimed at the regular miner's market, this existing hardware is very real and I've gotten it working with the latest cgminer from git with the existing hashfast driver without major changes.

So what's the differense between S and simple 110? Less hashrate, less power consumption - is that all?..

p.s. oh, it should be silent now, why not cheaper?..

Quieter.

Excellent news - better late than never eh?  :D

If only all the others would do the same........

Anyone own these miners?

Like I mean an actually paying customer.  ;D

Want to get some feedback from them on the experiences with this company.

Hi I am an actual paying customer. For full disclosure one of my gadget companies GeekZen is also now an authorized distributor of BitCrane as well. I only entered into the distributorship after I had purchased the miners myself and was happy with it.

I have bought two of these units mainly for fun as a BitCoin enthusiast and I wanted to be an owner of one of these sweet machines. To be honest, the reason why I bought two was because I wanted to use their EZ Stack system.

I made a video of this as well which I just uploaded today.

http://youtu.be/OCaC9v_XyUw

Shipping

Super fast shipping and they really make it a point to get them out as fast as possible. When there was a China public holiday upcoming, they did their best to rush it out and send it to their courier before they closed for the holidays (and kept me informed throughout the process).

Setup

Setup is as painless as it can be and is almost plug and play beyond the setting of IP and pools. DHCP is still not an option with these miners due to a lack of a LCD (which should be incorporated given the premium price point).

Hashing Speed

Hashing is stable at 1075-1095. No issues reported with a variety of pools. Slight loss with P2Pool (but what miner doesn't lose speed on P2Pool nowadays).

These things run super hot and in an air conditioned environment run about 85C according to the interface which is pretty safe according to BitCrane. The chips are safe until about the 110C mark after which it will shutdown and reboot the miner. Air coming out of it is actually not that hot probably due to the water cooling system.

Hardware error rates (if DH is what it means) is about a stable ~0.14%

Interface

Simple and fuss free. Their own custom interface which displays just the necessary. No password protection however.

Uses a Cubieboard controller with SSH access available and unlocked.

Noise Level

Noise level is average for a miner, the T110 doesn't have any dynamic fan control unlike its brother the T110S and therefore runs at a fixed noise level. Quieter than an A1 Dragon miner. The T110S is a slightly lower clocked version (around 900+ gh) with dynamic fan control and better power efficiency and quieter hashing (due to the lower clock) and has full CE certifications for the home. I haven't tried the T110S personally though.

The T110 will not bother you if you put it in a separate room.

Support

The support provided is very good. I ran into a problem with one of my units whereby one of the hashboards was not properly being detected. The guys at BitCrane teamviewered me and had a really fast response time. The issue was pinpointed to one of the water cooling heads thermal paste being not so evenly spread and hence one of the chips was overheating. According to them, this was the first time they've encountered such an issue. Since I've reapplied the thermal paste with Prolimatech PK-3, temperatures have been stable and low and no issues with hashing. One of the best if not the best support I've experienced from a BitCoin mining machine company. They've also informed me they're looking into their thermal paste application process (which is done by machine) to avoid such problems in the future.

Design

The design is really gorgeous. The EZ Stack system is pretty simple but innovative and allows it to be stacked up to 4 high. However it does result in a slight increase of temperature for those units being stacked under due to one of the side vents being obstructed. It shouldn't pose an issue though.


Summary

I would highly recommend adding them to the manufacturer trustworthiness guide as a stand up provider with a proven ship record. I have also sold a few units as well and all my customers received their miners without incident and very quickly.

My only complaint would be that they are rather expensive and that the warranty doesn't bear the cost of shipping back to China (unlike Bitmain). The build quality however is pretty amazing and the amount of thought they put into the design is outstanding. I am looking forward to their new miners which should be just around the corner.

If you're after profit solely, then these not miners are not for you of course (as are most miners if not all miners on the market right now not being profitable) but if you're after a solidly built miner from a reliable company, then I would recommend them highly. With all the other miner manufacturers cutting cost, it is refreshing to see a manufacturer that bucks that trend and insists on putting out quality products. It is actually quite sad sight to see when previously good companies cut corners such as the Dragon A1 miners steadily declining quality and Bitmain's recent issues with their S4 but it is understandable given that they want to get miners out as cheaply as possible to increase the chance of ROI. For those of us who are in it for the fun of it and want a solidly built machine that you'll feel proud to own, BitCrane is an excellent choice.

I was not paid for this review nor given any free units.

I have personally tested, bought and used several versions of A1 miners (From LKTec, Bit-Winkor and FZ49), ASICMiner Block Erupter Cube and Tube miners, Bitmain (S1, S2, S3 and S4) so have a good basis of comparison.

Love to have a few when they get competitive.

Also looking to get some. But after the bitcoin price rises a little more.

$1300 for 1THs is so 6 months ago! Lol. Who on earth would pay that much these days? You can buy an S4 and get 2THs for the same price.

That's why I'm waiting.  Even the S4 with a coupon is still a little overpriced.  You can pick up used Dragons in the $400ish range, so $800-900 should be the sweet spot.  But what do I know, Bitmain seems to be doing well.

Yup as mentioned they're not price competitive now but I understand that they are releasing their new miners soon that will be more price competitive but would still be aimed at the premium segment.

But then again, we have people still buying pre-orders far into the future...and some would argue, buying miners in general is a bad idea if you're into ROI.

My experience with S4s have unfortunately not been good and no one has replied to my request for the PSU replacement.
Watch your ROI go up literally in smoke: http://youtu.be/uiZPOZcI20o

Also one of friends who bought a S4 from me as well is having dead ASIC chips :( and these reports do not appear to be isolated. The S3 was a much more solid launch.

For some people, they just want to say 'hey I mine BitCoin' and for those sort of people, this miner is perfect but I would personally wait till their next gen which should come pretty soon.

I really don't like Dragons A1, their behaviour with certain pools can be finicky and you have to play with difficulty. Their cgminer is outdated and probably will never be updated. Support is shit. The PSU quality has dropped as well and if you open up the innards, it just screams CHEAP. It does its job of course and that's what it's supposed to do, work in farms...without care of noise level or nice interfaces or support of a variety of pools. But for home miners, it probably isn't the best choice.

Here's an idea on the hashing stability on one of these.

6 hour chart of hashing speed.

Redline is 1.1th and black line is moving average.

Still no one who is a "real" consumer?

I guess no one wants these as they are way over priced. Mind you what isn't these days?

So hang on, each one of those units is what 3U or 4U in height?
And all together it looks to take up to 15U in rack space?  :o
Uses between 4600 and 7800W  :o
And generates between 5.4 and 7.2TH/s of performance?  ???

[edit] WTF where did that post go?

Was moved to this thread (the old T110 / company thread).

It was such a hungry beast it ate itself........ :D

until 20 days later, when dogie regurgitated it  :-\

With added VAT......... ::)

:)))))) u guys are killing me!

So how thik is this, 3u?

Each half unit is 7.4U, so 15U for 7.2TH.

No the entire 7.2TH is generated by 4 of those 3/4U sections, plus another couple of 1U used up by the bottom shelf bit and the top controller.

So anything between 14 and 18U depending on how big each section is.

Thanks for clarifying.. so 3U per unit, plus 1.4U for the racking and controller?

Hosting costs will be a nightmare unless they can host it for free themselves..

Hell shipping costs are going to be enormous!

Nothing to see here. Train wreck. New or premined units? That is a fair question to ask given how LATE these are compared to other offerings something just doesn't smell right. Seems to be desperate ploy to dump either old hardware or weak large inefficient miners to the community. Avoid it.

Really? Not sure that is a good sign. Who runs Bitcrane?

I don't have any more info than you, going off the specifications.

Weight per unit (so 2 of them per 7.2TH) is about 20kg packaged each and likely 25 or 26kg volumetric each.

I can't see how they plan on selling many of these  :-\

Shipping to the US:
Product total: $4668.00 + Insurance: $28.01 + Shipping Cost: $385.29
Total Amount Due: $5081.30

Shipping to the UK:
Product total: $4668.00 + Insurance: $28.01 + Shipping Cost: $578.96
Total Amount Due: $5274.97

They have been selling systems with hashfast ASIC's for quite a while now.

They are based in China. http://www.bitcrane.com/article.php?id=5

Wondering why not make a HW for home miners... about 2-2.5 Th, less than 0.6 W/Gh.... Why don't they?..

Perhaps you don't realize what it means for them running Hashfast boards... In short not really feasible to get that efficiency without blowing the cost way up to run them underclocked..

By blowing the cost up, I assume you mean buying all the extra boards, water cooling, and PSU's will you need to get 2-2.5 TH/s at that efficiency?

Those HF boards are power hungry. I loved MrTeal's boards, but I broke both of mine.

Define broke?

Just to clarify it's not 'between' there are two modes. a normal mode and a turbo mode. The normal mode is more power efficient but the turbo mode goes at full 7.2 TH/s at 7800w.

doesn't matter! just buy an s4 or spondoolies!

Hosting costs would be higher than the unit is actually worth

tomorrow, Spondoolies-Tech are reducing the price of the SP20 to $695 for only a few days in a Cyber-Monday sale. That's 1.7TH/s of the most stable miner on the market, from a company with a proven track record of delivering miners.
All I see on this thread are newbie accounts who have received what seem to be prototypes of the bit-crane hardware.
I'd advise members to do some proper research before sending money here.

So that doesn't have anything to do with the big ass affiliate link on your sig, does it?

And your sig is...

LOL.
