@HashFast_CL

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!

That post aught to be deleted. People keep believing it.

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


Is it not cruel to get our hopes up that these machines would be delivered in November?

Dozens of pages in this thread are community members shooting personal attacks at each other because of the ambiguity of the refund policy - would refunds come in BTC or USD, if customers paid in BTC and at what exchange rate... These are people who don't know each other and have no beef with each other otherwise. HashFast will obviously have a concrete refund policy at some point - is it not cruel to withhold this information instead letting people be mean to each other?

Disinformation only exists in the vacuum of real information. You can easily solve this problem yourself and I appeal to you to do so.

(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.

Maybe I am stupid... But I read that probably 20 times in the last 2 weeks and kept missing the critical line:

exchange rate given by Hashfast to its customers on the order date

I feel less panicked that they would just miss the deadline and refund everyone at the new exchange rate rather than the exchange rate at the time of purchase. That is not an option.  

I am now reassured that the have proper incentive to ship whatever they have before the deadline.

Refunding BTC using the exchange rate at the time of purchase is the same as just refunding USD.

None of batch 1 customers agreed to that terms. Will you stop, idiotic and failed puppet that you are?
Do you really think that your stupid posts will convince anyone of your agenda?

@aerobatic

Thank you for spending so much time to write down your thoughts.

But personnally I think the temps are too high.
Wait till you run it in summer or a warm country or run them in a room with other asics.
You can't depend on AC all the time too keep them cool.
I don't use AC.

 Woops you are right.  I had it backwards!!

Well now it is clear there is no incentive to get it done on time as a refund would just be locking in a 90% loss (in equivalent btc).

If HF is going to use the new tos for the B1 guaranteed delivery date then they are going to use it for the refund policy.

You argue about whether or not HF is going to refund in USD or BTC, when the answer is quite obvious. They are going to refund in USD just as the current terms of sale states. Then you argue that the current terms of sale doesn't apply to B1 customers. However HF is going to follow the new terms of sale regardless of it being applicable to B1 customers. They didn't follow the original terms of sale for the delivery date, and they are certainly not going to follow it in regards to refunds.

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:

Really? This topic is not about your marketing nonsense, it's about your promises (they are in the title) that you keep breaking. It left a lot of people cheated and poorer. Your whining for a mod who will shill for you is laughable.

Harrison, Hashfast is not legally free to impose new terms on old sales.  The terms that apply to any given sale are those terms stated at the time of sale.  Some people seem to have great difficulty understanding this.

Now, yes, Hashfast might be silly enough to try to argue that it can apply ex post facto terms, and they might convince some dullard customers that it's okay, but such an argument won't last 5 seconds in a legal proceeding.

But the real problem for them (and us) is the October delivery fraud.

I agree, and understand that it is not legal. The point is that they don't seem to care, and probably won't until someone sues them.

I didn't order an asic from HF but if I had I would much rather just get an asic even if it is late. I did make the mistake of pre-ordering a bfl product but I was able to sell the asic when I got it for a profit. It is a huge mistake to preorder hardware from a company that has never delivered a product expecting it to be shipped on time.

I don't see why we should be happy about getting our ASICs delivered late, unless your only objective is to sell it on to some other poor sap and screw him over. I hope most of us bought the equipment to mine with, not to speculate. Mining implies we need to recover the amount in BTC we paid otherwise we'll never break even.

Past performance is not a guarantee for the future, ask that to those who ordered batch #3 from Avalon. Or compare that with those who preordered from KNC. First case Avalon had already successfully delivered 2 batches but ended up screwing all their later customers (batch #3 and chip orders). KNC had never delivered a product. BFL has now delivered FPGA's and ASICs but no way anybody should ever order their Monarch (unless they want to repeat your initial BFL experience)

Batch 3 and chip orders were both offered a 100% full bitcoin refund.



Not true.  After all Batch 3 were delivered, they offered refunds to anyone who hadn't received their order.

@HashFast_CL

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

So which lawyer is taking on hashfast?  They will not be able meet their dec 31 2013 deadline or maybe no lawyer is needed for full BTC refund for batch 1 users...

Bitcoinica still has not given me 50% of my claim of 600 BTC
INTERSANGO can go down with bitcoinica for abandoning customers

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.

Jesus Christ, I thought I made it more than ludicrous enough that no one would believe it, especially since it's just a copy and paste of the last update. I guess I should have added a line or two about the new Dyson Sphere that's going to power the Sierra arriving for testing.

HashFast_CL, people wouldn't have to waste time messing around with jokes if you would actually give productive updates on where shipping is at and when you plan to start moving out the units. I'd also like to know who you are and what your relationship is to HashFast. I can't help but feel that we've been thrown another random poster like cypherdoc who supposes to speak for HashFast but when push comes to shove does not actually represent them and can't speak for them.
Are you directly employed by HashFast and do you have the authorization to speak for them as their agent?
