Topic: Hashfast troll fest split from the cointerra thread (Read 2069 times)

it is now!   

hijacking of the CT thread is not OK! 

gotta have some place to mount the radiators, one per asic.  running caseless is possible but impractical.  the dc/dc converters will get very hot and you need good airflow over them...  a case makes guiding the air easier.  and mostly, a case gives you solid walls with screw holes to mount fans and radiators...

i guess this topic should probably be moved to an hf thread so the trolls can have their 'input' ;-)

you guys do realize that this is not the HF thread right?

o, and by the way.. whats a case?    

Uh oh. He said they won't ship in December. That must mean January shipping!

that one's no good.  the radiators need more than 120mm each...

probably best to not worry about the idea of putting 4 modules in a single chassis, its going to be a very tight fit and it'd be easier to stay with two chassis... s you'd need two power supplies... and lots of module space... and 4 radiator bays.   its not going to be easy to fit 4 modules and their separate coolers in one chassis...!   of course, you could do your own liquid cooling and not need 4 radiators for 4 modules and use bigger radiators shared across more than one asic (a la cointerra's design).  but they're not using standard radiators.

This is a decent starting point for a 4U case with 4 modules in it:

I guess that we should start engineering it (and not wait for HF to release it's pricing, i don't want to pay them a dime more than theirs production costs).

(just realised that this is not the HF thread)

4 modules might fit comfortably into two pc chassis.  if 4 modules fitted into only one pc chassis, hashfast would already be doing it.  presumably the physical space for the radiators... and the airflow for the coolers doesn't work out well trying to cram 4 rads and 4 modules into a tower chassis, hence why they only put two into a baby jet and three (with one double decker) in a sierra, with twin atx power supplies - which is a custom case with room for the two psus.

so, two decent tower cases... $100 each?  (total $200)   if each module uses approx 1w/gh (as per their latest spec on the sales sheet from a few days ago at Inside Bitcoins conference) and each chip clocks at 500 GH... then for each two modules you need 1000 watts.   if you include the fans, pumps, psu losses, controller etc... then lets say 1200 watts should cover it.     two 1200w platinum psus approx $300 each (total $600).   two raspberry pi's (one for each chassis) with sd cards etc $50 ea (total $100).   Two Corsair H80i coolers ($100 each)  so, if you build it yourself... your cost of parts alone, with you mounting the MPP 4x modules is $1,100.   So presumably hashfast would easily get away with charging circa $1500, to offer to build it for you and save you time and hassle (and their buying power would give them a better margin than you could get from new egg).  And i suspect they could easily charge more... and many people would take it, to know it was done for them and working.

STOP spreading lies around!!

Agree the prior post does a bad job because it is x GH/s for delivery in Dec/Jan and then 4x GH/s for delivery in Feb (April? May?).


$500 to $1000 per board?  HF would be asinine to try and charge that.  The good news is a user could simply by their own gear.  User needs to supply power supply and cooling module.  $60 per board for cooling module and if the boards use 250W to 300W ea that is 1/4th a 1250W PSU or say $80 per module.  So maybe $140 per module or $640 for four, plus some DIY case and a couple screws.  Someone would be downright stupid to pay $4,000 for that.

icetard is the new Inaba and he is way more fun than retard Inaba except that icetard won't make any seppuku announcements

BFL pays Inaba...

Well at least we know ice isn't a shill, since there's no way HF would pay someone to make their supporters look like lunatics.

its certainly harder to calculate the cost and value of the hashfast equipment with the MPP.

its a complicated offer to evaluate isn't it?

i mean, after a long period of time you get some of the pieces to make the rest of your miners, but not all the pieces, so no doubt they will happily sell you the systems with mounting screws, cooling systems, power supplies etc... for.. I'm guessing $500-1000 each, and you'll need 2 or more than them.. right?... on top of whatever free mpp gear they're going to give you.

the main thing is the delay.  you won't get it til feb or march or later. right?   by then, its worth a lot less to anyone.

you can't equate the cost, up front of buying mining gear if you get some in dec, and the rest in march.  that doesn't average out at a $/gh number since they are separated by such a large time gap that the mining economics are very different in the two batch delivery timeframes.

sure, it brings down your cost of buying mining gear, but the mop gear arrives so late that it barely is helpful in making you break-even.

and instead of delivering to you something on time that will earn the btc you expected at a power cost that you expected, you will instead have to front a 5-10x power cost (running a lot more equipment for a lot longer) to yield the same btc.

in short, the mpp isn't a win win.  its a token gesture with a lot of strings attached.

Wouldnt you rather have had double hash power on the day 1 delivery, then have 4 times the hash power, 3 months later ?   4 times th e hashpower is 4 times the running costs.

Yup, and when CoinTerra is 2 months late, then they'll get the same treatment.

Aerobatic Firstly I should say that I respect your posts as they have generally been neutral and not biased for, or against, any of the ASIC suppliers / wannabe suppliers. I also think HF could be more open as to what has caused their delays. However to be fair, I am not sure if your pricing comparison below is correct as if the full MPP for HF is triggered (which i am sure is highly likely by now), then surely the correct price comparison for HF should be $2.80/GH for partial delivery in dec (assuming that deadline is met) and the rest of which depends on when the MPP is finally delivered? So unless my calculation is wrong, is their late delivery not also priced in?

youre ignoring the price in that equation.

hf charged $14/gh for october delivery, and now might deliver in december/january.

ct charged $7/gh for december and $3/gh for january, and let people switch between the two batches at whim, thus most will get their january order, in january, at january prices.  no one has reason to be upset at that because the delivery date has been priced in.

Not that this is an excuse for HF's poor communications or to stickup for IceDrill but he does have a point (albeit an overly exaggerated one) that the same principles should be applied to all the ASIC suppliers or supplier wannabes

You would have much better success arguing with a wall

No, you're not making a point, Aerobatic was right. You are certifiably insane!

 

Notice how you deleted the quote that proves you wrong? I'll add it again. It's only 6 words. I know a couple of them have a lot of letters, but try reading it again. Here it is:

I am a cointerra customer and I feel no need to be angry yet.  We are not hashfast victims, and everything is looking good.. I would much rather wait until january and pay half the price if i have to.  That is very considerate of them
