I'm planning to visit the HashFast office in SF this Wednesday.

It will be a fairly short affair (30m), but I would be happy to relay some forum questions in person. No guarantees I'll get answers though

Ask them if they are thinking about announcing MPP starts November 1st, regardless of the late delivery date. That's the least decent company would do after messing with their product value and company reputation so hard. If they answer you they are not even considering it, than I know what to think about them.

Ask them when we can expect the MPP to be delivered.

It kicks in with negative ROI 90 days after delivery, but how long will it take after those 90 days till we receive the MPP-boards?

well, ask what they are going to do for batch 1 BJ owners as the prospect of earning positive ROI is now close to 0

Thanks for the help

The question:
- What to do to change a BJ ordered into a sierra ? Or if you like, will you change the first batch BJ into sierras as a compensation for the delays ?
   If they say no. Why not ?
   They will say again that the hardware of the BJ have already been ordered (even we have not seen any pcb or board). The hardware of the BJ is the same as for a sierra: modular boards with chips, raspberry, psu and cooling. All the same except the case. I will pay them the case if that is their next excuse.
   What I want is to have the 1,2TH as the second batch of sierras will have in the 10 days of difference between batches. Its them fault to manage so bad with them marketing and delays. With this 1,2TH we will be able to ROI and wont have to apply for the MPP, so they will earn those chips in the future. I think lot of people, if not everybody will switch into a sierra and refuse to the MPP. At least give us the chance

- Any pics will be welcome, especially about the pcbs they claim to have ordered

I can confirm that, he also said that he has been doing that with every customer that requested it, as if i wasn't the only one.
Anyway, that will only be useful to me because of the space the BJs would have taken into datacenter racks. Now that i have sierras cases, it's almost 1/3rd of the monthly bill.

I don't think that this advantage applies to many others.

They will deny you to move on second batch because it's 1/3rd of the price 10 days later, but they shouldn't have any problem moving around some boxes of fans.

There seems to be variance on that topic.

Anyway, since that i have 3 or more BJ in order, John offered me an upgrade to the sierra case.
I think you if you ask, they should offer you the same.

Pics of the boards, fpga demonstrations, etc.

Okay. I don't think they will have any hardware in the office, since all manufacturing and assembly is done at other sites. They will probably have the FPGA hardware and simulation, but there is already a blog post about that. But I'll check with them regardless.

Proof that they are real and they only had a problem, in other words.

I have no doubt they are real. I met Simon at a Bitcoin Meetup back in April of this year (months before HF was started) and he was already working on a design for a 400GH/s mining ASIC for some time at that point.

BJ Batch 1 with Upgrade Customer: What can be done to change my order to a Sierra without later delivery date? (Support already said no).

Will do. However, if they have already ordered all the BJ cases, and support already said no, I don't think the answer will be different the 2nd time. But who knows?

I don't think pulling wire is that likely, at least probably not with recent construction in a place with code enforcement. Standard here would be a 120v 20 amp circuit on 12 gauge romex... I'm not an electrical engineer, but shouldn't that be sufficient for nearly 2000 watts constant load? I've done a little bit of homeowner construction to code, and they make you run a separate circuit for just about damn near everything these days, except lights... I guess the concern would be if you've got an old 15 amp circuit on skinny little wire or hooked up to your air conditioner....

120V, 20A circuit is solid for 1920W continual, 2400W peak. Most household outlets, branches, and breakers are 15A though and that means 14 AWG. Might be better in newer construction but wire is expensive and builders are usually cheap.

If someone is looking to do an upgrade just do it right with 240V, 30A branch. An outlet like this is good for 5.76KW continual and ebay has tons of cheap used PDUs which have a NEMA L6-30 plug.
http://i01.i.aliimg.com/img/pb/752/466/477/477466752_353.JPG

Probably good for at least 3 Sierras maybe 4 depending on what final wattage ends up being. My guess is HF puts some overhead in the PSU so 1700W of PSU doesn't mean they intend for it to draw 1700W. Drawing say 1300W would keep the PSU at 80% load.

Please don't burn your house down over this shit, people.

So it looks for those who purchased batch 1 BJs, they are never going to make their money back??

They will get back 10% if delivered before the first of December, 25% if delivered before middle November (the now promised shipping date).
If HF stood to their promises, we would have had back around 60% of it, and then the MPP would have kick in. (that maybe would have gived us another 10-20%).

I do not want to come off as a jerk, but I am surprised it is that low.
We ship to europe through fedex from the USA and the costs are enormous. Not just for the airfreight portion. The largest costs are: brokerage fee to pay customs clearance/duties and VAT, then duty (I do not know what it is on this product but on ours it is 9%) and then of course VAT. As you know, in Poland VAT is 23%. If they are delivering the box to your door there would be all those costs. I would think you could go into UPS or Fedex and type in the cities and then type in the weight (have to guess but 30-40 lbs sound right? And you will see what it costs just for the delivery.

Thank You. Ive been emotional because ie: KNC package cost 200USD and I had it next day at my door. I forgot all the hassle with VAT etc. I think shipping costs can prevent people form europe to buy HF miners as shipping will play big part of whole costs (BJ december for 2250USD+700USD for shipping).

Pro:
They have proved that they can design a case with a not that dumb airflow and produce it. We will just have to flip the PSUs 180° if we need that in a rack, but it's ok.

Btw d&t, your posts are always a pleasure to read. I love people bringing numbers and facts to a discussion.

I agree on your comment on DeathandTaxes. Good quality comments and more than willing to help everyone. Thanks D&T.

I do not think you are correct on the PSUs though. The typical rack is 19" at the rails but is 23-24" wide. between the case and the wall of your rack you will still have 2" minimum of space. I believe this is the inlet (on the side) so you will have lots of airflow of cool air for the PSU and it will exhaust in the back. Even if it is the opposite as people have said, it is still not that bad. The heat will not be that much and since it is at the back on the side the airflow will still pull it up the heat aisle and away. I would not modify it at all.

Sorry but I think those 700$ are just for shipping. I mean then you have to add any cost in customs, fees of the VAT and so on. That is something that pays the customer, not HF in this case.

Eventough, I have been shipped and old 1984 mac from the US to Spain for 120$ and for sure is much heavier than the units HF is shipping that costs me 375$ which I think is pretty abusive. I will have my unit hosted of course.

Sorry for the offtopic Wink

Shipping to Poland is more than 700USD Shocked

Does HF CEO shake my hand personally and confetti will be throw out of the plane flying above my street Huh

But honestly - wtf?

Hehe, I dint know that was an option. Where do I opt for the HF Ceo hand delivery?

hashfast is keen to announce with whom they are buying the screw to tighten the pcb and else

does any one know when they are really going to deliver

...
Actually, a 1600W power supply running at full load will not run fine on a 120V 15A circuit. Even a very nice one like the Lepa G1600 will pull over 1800W from the wall, and no circuit should be run at 100% load 24/7.
A 20A circuit would probably be fine, though you can't just swap breakers as you'll almost certainly need to pull a new cable. If you're going to go that far, you might as well just run a 240V line.
Either way, HashFast never said the Sierra even under full overclock that the Sierra would use 1600W. I highly doubt they would be able to anyway, those modules are almost certainly not designed to supply or cool ~500W each.

You're right, as usual. The breaker swap, of course, is not code & i should have prefixed it with "Kids, don't do this without parental supervision." That said, i've continuously sinned against humanity by doing such swaps. Torched houses: 0.

Also, good point about the reality of twin PSs being unlikely to actually *use* separate 15A circuits. Images of orange extension cords stretched into adjacent rooms come to mind Cheesy
