Yes, looks like HF made some stealth-edits to those specs already:

That they changed the specs of the chip overnight. From 735 to 664 GH/s

https://bitcointalksearch.org/topic/m.4247859

I'm sorry if I sound a little cynical about all this, but Hashfast's end-of-2013 announcements seem a bit odd, to put it mildly.

Firstly, they claim chip performance of 'up to' 664GH/sec. Real engineers don't do 'up to', they quote maximum and minimum and specify under
what conditions each is valid.

Secondly, they say this performance test was " conducted by running a single GN die directly from bechtop power supplies, as opposed to powering it through the module". I'm assuming by die they mean one of the 4 functional blocks. Why not use the actual system power supplies? Something wrong with them?

Thirdly, because "This approach allows us to obtain data about what the ASIC itself can do, without having to make subjective estimates regarding the efficiency of the power supply on the module. However, doing things this way also has it’s own set of disadvantages.For example, the reason we are “only” able to announce a top speed of 664 Ghash per chip is purely because that’s the point at which we ran out of power to put through the chip. " then that means their chip, with all four cores running will use 664GH x 0.67w/GH = 442 watts, all from a  silicon ares of 664/2 (their figures of 2GH/mm2 of silicon), ie 332 mm2. This, frankly, is impossible. You would need a heatsink with a NEGATIVE thermal coefficient to keep the die junction temperature below 75 degrees C. As far as I'm aware, none exist.

Can't they afford a decent PSU?

Anyone else care to add their observations?

Just to say there's no NDA been violated - the NDA in question related to a specific design implementation and the detailed commercial figures (which I never saw). My contact was very careful to screen his information - if I had never heard of Bitcoin or sha256 I would have assumed this was some kind of encryption device.

But thanks for your comment, you're absolutely right that NDA violation can result in heavy civil penalties.

Anyone who has heard or spoke of it has violated an NDA and risks a lot of fines and possible criminal prosecution.

Sounds legit to me.

Then why did my email not have a tracking number but some big long refund or wait policy instead?

It's been a while since I looked on this forum. I'm really disappointed to read about what's happened with Hashfast as it looks as though a lot of trusting customers may end up losing a fair portion of their hard earned money. That's inexcusable as it would seem that HF got more than enough funding to develop a 28nm chip and build their customers' systems. How much they took out of the company in expenses and salaries is anyone's guess.

It's also going to make life very difficult for any new suppliers that  might come along, and that leaves a bigger problem.

I've always felt that mining rigs are grossly overpriced, even at the current lowest offering of $3 per gigahash. It's simply not competitive with what the 'invisible' mining corporations can build capacity for, ie less than $1.50/GH. Think I'm kidding? Well, let me give you some insight....

Recently a previous colleague of mine got in contact. He works for a group of Venture Capitalists in the UAE and had been approached by some of my fellow countrymen with a business plan for the development of a 'consumer' electronic system - he wouldn't tell me what the application was as it was all under Non Disclosure agreements, but basically he asked me to check out their technical plan -edited, of course - and their costings. When I went over the facts and figures it became obvious that the plan centered on a custom silicon device; from the power specs, huge heatsinks and unusually low clock speeds it spelt out SHA256, or 'transaction engine' as my contact called it.

To cut to the chase, it was a very comprehensive and well thought out technical plan with realistic timescales, although I thought some of the costings were a bit on the pessimistic side. It's a real pity the plan I got was so heavily edited as it referred to 'commercial **** companies dominating the market with proprietary systems' and had several graphs and tables totally blacked out. It did, however, refer to a 'Network ##### Rate' and how much they expected it to grow in 2014 - to over 180,000####### by Dec 2014, no less. Whoever these 'companies' were, the guys that wrote the plan seemed to really disapprove of them.

But here's the killer - in their plan a basic system using one 'transaction engine' would retail at 'around' $300 with a manufacturing price well below $200 - I can't give you the real figure - including one-off costs! This system had a 'rated capacity' of 200 billion ###### per second, I'm pretty sure I don't have to spell the rest out.

My UAE contact said his principals were very impressed with the plan, but only if the systems were used in-house, as it were, due to their  potential ROI - I never got to see that part. They most certainly didn't want them sold to the public under any circumstances. He hinted that a very attractive offer was made to the group, but was politely declined. He wouldn't tell me who the group were or how to contact them.

It's a very interesting thought - a 200GH miner for $300?? Anyone heard any hint of this?

It's too bad your terms of sale specify refunds are available for all Batch 1 customers who don't receive their miners by... oh look... today!

Good luck on your illegal scammy attempts to refund people a small fraction of the BTC they paid you, too. I sure hope you enjoy getting sued.

good news... well done!  can you mention how many were shipped today?  and whats the schedule for the rest ?

A big thank you to Amy for camping out in Montreal for the last week!



We did it!! Shipped the first Baby Jets and Sierras today.

Don't believe their bullshit refund terms, it's a trick to get you to forfeit your rights.

Pretty bad news guys.. I think it's worse than everyone here thinks. I don't think they are EVER shipping and probably not refunding either. No, I'm not privy to any special inside information, but...

1- goofy refund policy that states it's only a "request" for refund
2- just about 3 months late at this point
3- YouTube account has been terminated

To me this means ..

(a) they intended to deliver but ran into serious issues, were severely undercapitalized, and burned up.most or all of the pre-order cash.

Or

(b) they never had any intention of delivering

Delays are not the frightening part. That happens. The closed YouTube account and the refund policy that's a "request" are the reasons I fear the worst.

Can anyone else verify the refund policy?

wow, people paid in btc for a miner which delivery date was a lie now get back the current $ amount ?  W O W


how can you let hf go with that ?


knc received a shitstorm for every spelling error. 


 

Just so we all are all ABSOLUTELY clear: how HF used of any funding is NOT our fucking problem!!

HF,
Refund 100% of the payment (which was done in BTC)!!

It's also illegal. I hope people don't fall for it.

HashFast has now announced they'll be missing their "guarantee date", and are attempting to renig on the above. Now customers must choose to lock in an 86% loss or lose all potential of refund:

I'm sorry, but the thieves at hashfast are a us based company, and better learn the fucking laws about doing business in this country. They will get fined everything they have made and lose any lawsuit filed if they don't.

Do not accept any of their excuses as a customer, do not let them tell you that they are not sure you are eligible for a refund. File complaints with the FTC and your state attorney general. DO NOT LET THEM GET AWAY WITH THIS.

its a Raspi (supposedly). Last i checked they use  hdmi

What I would like to know is what type video output does it have and is it male or female plug ? You just never know what will come on a machine when it is not listed in the specs .
 I assume it is vga with female  but who knows .
 Also assume it has it's own ethernet card  . Wonder what speed that is .  They need to put more info on their website about their products .

I think he nailed it
