Why there are so many heatsinks on the testboard?
Why does the GN chip gets to 76 C degree, even when it is underclocked?
Why does the GN chip gets so hot, even with watercooling?

im not in any way related to hashfast (am just a customer) but here's some thoughts...

a test board & box may well be different from a production box.  they probably have to have extra capacity of power & cooling in there so they can run it at beyond its normal limits and see how it performs... so to assume that the production boxes will have to be the same isn't necessarily so.

i really don't think if it runs at 76 degrees at 424 gh that this is technically 'underclocked'.  and anyway, i think the word underclock may have been misused.  generally underclocking would also require under volting (to reduce power consumption).  so its possible they mean that its running at under nominal voltage.

at 76 degrees, there isn't much more room for over clocking.  I'm presuming that most engineers don't want to see their chips to get much hotter than 90-100 degrees in extreme overclocking, and at 76 there isn't a lot of margin to play with.  it really cant get much hotter than 76 and be run for long-term reliable sustained use.

presumably they are playing with different voltages, and clock speeds as we speak.. to see what makes the most sense for long-term use.

the documentation hashfast put out showed that when running at nominal volts and clocks it should run at 424 gh/s... so to then call that 'underclocked'  is odd as that was the intended gh rate (according to their docs)... so yes, it does seem likely it can run faster than the nominal clock.. as most things can.   5-10% should be easy.  And the 20% they were gunning for, with some extra volts, should well be possible.

the earlier claims of it running at 500 gh may have also been true, but they also specified that with half the cores running it was consuming 300 watts.. which is clearly too high and if the other two cores also consumed 300 watts, the total of 600 watts would be much too much for that package and cooling system to cope with.  This may have been putting a strain on the rest of the system and it may well be that to run at 500 gh (or more) for a sustained period will require everything else in the system to be behaving itself very well (power, airflow, dc/dc converters, cooling etc).

its not difficult to overclock something for a few minutes... but try and run it overclocked for hours or days and the rest of the system needs to be able to cope.  fingers crossed, it can as I'm really hoping my hashfast gear will clock at 500+ !   but i will still be happy if it runs at 424 gh!

(j)       REFUNDS.  Any refunds due to Buyer will be made in United States Dollars, and for the purposes of calculating refunds, amounts paid in Bitcoin or other virtual currencies will be deemed paid in United States Dollars at the exchange rate given by Hashfast to its customers on the order date.  Refunds for partial order cancelations or returns will be adjusted for any discounts previously given to Buyer for volume purchases.

I reported that post for trolling and disinformation.  It's especially cruel to new members and non-native English speakers.

But Gmaxwell choose to further confuse HashFast customers, in order to punish HashFast.

Time for a new, less-petty, more even-handed Hardware Mod willing to objectively enforce (and follow) the rules set forth here:



Closer and closer to being an Inaba.

Maybe instead of complaining about people making up fake updates, you have someone with authority back at HQ give a proper update... Even if it is bad news, being in the dark is not helping anybody.

I guarantee you, whatever problems they are trying to solve, the problems the community believe you have will be much greater left to our imaginations.  The community might also think of some solutions.

Wow really?

After all of our questions, lies, and waiting, you refer us to the forum rules?

Nothing more pisses me off than making a valid argument to someone and they switch to another argument as a comeback.

For someone that has about 100,000$ of mine (not in BTC, in USD), you are starting to piss me off.

Give us something informative. I'm getting tired of the ongoing lies.

Any tracking numbers send to customers today?
I think the majority of your customers become sick from waiting.
It's not our fault, it's a human nature.
People get pissed off.
Thank you for information

https://bitcointalksearch.org/topic/a-point-of-order-conduct-in-this-subforum-139380

Here are some points on this subforum's ground rules— some of them are just reptition of the overall forum standards. Most of this should go without saying, but it seems a few people need some reminders.

Stay on-topic.

All threads created should be about custom mining hardware, its operation, or its production (including the companies making it or the technology involved).  Generally the subject matter should be boring— technical, procedural, dry things. We're talking about custom hardware for mining here, not civil rights or awesome rock concerts.

Within a thread all messages should pertain to the subject of the thread which is described in the thread title or original post.  Avoid tangents and especially avoid responding to tangents.  Off-topic posts may be spindled, folded, or mutilated at the moderators discretion.  Posts by an equipment manufacturer or their staff in a thread about that manufacturer are automatically on-topic regardless of their content. (If they want to make a fool of themselves thats something everyone would find interesting)

Posts should generally not make people angry. If you expect that your post will make people angry that is a sign that it may be in the wrong sub-forum. However, in some rare cases factual material about custom hardware or its vendors will make people angry. In these cases it is all the more important to be dry, factual, and to avoid speculation.

In all cases, do no harass or stalk people.
Keep your behavior civil and professional.  Harassment will be ruthlessly deleted or edited until it is a mockery of the poster (in all cases edited posts will be marked accordingly). If you are in doubt about a behavior it is probably harassment. Don't do it. If you feel you need to investigate a party that has scammed you, take it to the scam accusation sub-forum.  Be the better man: Just because someone is a jerk that doesn't justify you becoming one.

Feel free to provide criticism but don't belabor it. Making the same point over and over again is spam. Making multiple threads about the same subject is spam. Spam will be ruthlessly deleted or edited until it is a mockery of the poster.  If you think important criticism is at risk of getting missed cooperate with other posters and write up a even handed summary of the issues.  Pointers to well written third party summaries may be stickied, if their material is reasonable and of general interest to custom hardware participants.

To avoid wasting people's time avoid bumping threads with pointless +1s, meme images, or "inb4" messages. Silence is golden. If you don't have something substantive to say, please say nothing at all. If you're not sure what the topic of a thread is either don't post in it or only post to ask for clarification.

Anyone got a tracking number now?
If they don't send those today or tomorrow, it is almost impossible to ship before 31 december.
I personnally already have enough of this fastshit.
Luckily I didn't order much from failfast.
I have almost recoup my investment in KnC Jupiters, after that the Jupiters will start to earn back the lost BTC in failfast equipment.
I hope you guys also have a backup to recoup your losses in this shitty BFL 2.0 company

the money is gone. even if you are successful in court. hashfast files for bankruptcy and the story ends.
And we get all the chips we want at fab cost. Fine for me.

yes, that might be a possible outcome.

the only problem: to sue them, go to court and receive the final judgment lasts at least several months. so we all could gather the chips in late summer at the earliest.

i dont think that those chips will be worth anything in summer.

I dont see any refunds happening.

- First of all there wont be BTC refunds. You may sue them and maybe you will be successfull. But initially there wont be any BTC refunds after the 31th.

- So the only option thats left would be to take US$ refunds. But why should any resonable person do so?

A babyjet was around 5000$ if i remember correctly. Thats about 8 BTC right now. So you have got the choice, take 5000$/8BTC now or accept the babyjet and additional MPP.

I think its pretty obvious that the babyjet+mpp will be worth more than 8 BTC easily. So nobody will opt for the US$ refund, period.

Only if you paid them $5K (in USD). I didn't. I don't know about you but I paid in BTC so refunds by nature are done in same quantity and amount they took so not I'm not worried about it irrespective of what the f*k HF does with those BTC, which is not our problem. Does the MPP state ROI in USD? No. it's also in BTC so stop jerking off mentally cause USD refunds don't make sense. :p That'd be total fraud right there getting filed with the Attorney General right away!!!

may i quote myself:

a bitcoin refund is just completly out of space. even if you successful sue them, which is very unlikely imho, there just wont be enough $funds to buy back BTC at this horrendous price at the moment.

those funds have been invested in hardware, thats it. learn to deal with it! denying reality wont help you one bit.

the money is gone. even if you are successful in court. hashfast files for bankruptcy and the story ends.

The Baby Jet will support 3 mini-boards. I was looking back at the pictures that gateway took, and noticed 2 additional sets of mounting holes. The case being used is a Corsair Obsidian Series 750D which supports an EATX motherboard. 3 mini-boards could fit in the same space that an EATX board fits in. The 750D also supports 3 2x120mm radiators, one in the top, one in the front, and one in the bottom. The only issue that might arise is powering them, but an additional power supply or two not mounted in the case might do the job.

I look forward to another productive day tomorrow, when we'll take all the BabyJets out of their cases, install the new 360mm radiators and 1600W PSU, and place some super cool and ironic stickers we found on ThinkGeek.

Cheers,
Amy

Gah. People there were pulling a prank. Relax. The power supplies are still 20,000 watts.

lol, you have HF orders also? welcome to the club!  Grin

they BayJet case has the option to install a upgrade kit. could it be that the 1200W PSU is for this two 500 GH/s modules together?

So for MPP they are offering naked boards, but for their first batch customers they install for free a bigger PSU for further upgrades? I just can't believe it, but we will see once units are in the wild.
