Topic: HashFast announces specs for new ASIC: 400GH/s - page 151. (Read 880461 times)

I think HF may need to retract that 'most powerful ASIC' statement: isn't this using a more powerul chip: http://btcolympus.com ?
and one of their customers with a working unit: https://bitcointalksearch.org/topic/--7216

Very well played until now. Hope it works out ok for them and for every customer.

It's a group buy:

Thank you cedivad for pointing this. Somehow i didn't even read it the first time. All i can say is WOW. You are a tard troll from my point of view after reading this. So KnC announces that they will have a 10 MW datacenter ready in a few months and you are telling us that "ALL" companies have chips doing nothing and that they can't build boards fast enough? O'RLY??? How does this picture look to you? So sick of dumbfucks who can't even do a little research before talking out of their ass...




Edit:
Who is Cypher Enterprises? The name reminds me of cypherdoc and that's so funny...

WAWW !  he he he 

S M I L Y.

It doesn't really take a lot to detect people with an interest/trollers of this thread. Just take his first line:
>As someone who has been in hardware development for many years,

And uses this authority to state that:
>ALL of these companies Im sure have trays of chips sitting on shelves doing nothing.

In order to defend the criminal actions HF is committing by gifting ASICs away in an unfair distribution.

Proof? KnC never ran out of VR modules. They even put more than needed on the first boards just to be sure nothing goes wrong. Yes they had some capacitors catch fire but i don't think it was for more than 20 customers which is ~5.5% out of 3600 Jupiters. But the units are stable as fuck. The other vendors hardware, even if they didn't had problems with components catching fire, they weren't so stable or they just died. So i'm waiting for proof for the statement that KnC ran out of VR modules otherwise it means that you are just talking out of your ass.

And so did CT. HF? Fucking December.

How not. Enough to gift a "few thousands" of them to Garret and possibly someone else (or many others).

I don't have time to read up on the other companies, but you are wrong to compare KnC to HashFast.  KnC finished their PCB design and had the PCB in hand ready for functional, power and thermal testing 5 weeks before their packaged ASIC chips arrived.  Yes, later on they encountered a shortage of the GE DC/DC power modules (they bought the entire global supply), but they came up with a good solution thanks to their over-engineering.  And that solution did not involved delaying shipment for months unlike HashFast.  MrTeal allured to possible supply chain issue with Hashfast, but who know if that's really the truth or if anything HF had ever said was true.  Regardless, I wonder what were they doing while they were waiting for their ASIC to arrive?  When did they came up with the PCB design, tested it and mass-produced it?  When the chip finally arrived?

Today we have our PCB’s back from the assembly house. These boards will each contain one ASIC chip and be individually connected to the main controller board. The Chip in the picture below is an FPGA which we are using to emulate the full functionality of the boards.
 
The entire space you can see in the middle of the  DC/DC modules (GE Critical Power DC/DC CONVERTER 0.45-2V 40A SMD)  will be consumed by our ASIC.  
 
We would also like to share some facts about our boards with you.
 

• The DC/DC modules we have on our boards are the largest and best quality available from GE Critical Power. Each capable of 40 amps making the max available 320 amps per ASIC
  
• Our PCB laminat is not standard either. It has been given extra thick copper layers and multiple power and ground plains which enable it to more than handle our requirements.
• We will be using these boards to fully validate the entire setup. They will consume the same power, make the same noise level, produce the same heat and run the same RTL code. The only difference will be related to hashing.

We would also like to take this opportunity to explain our design philosophy.
 
Our entire design strategy is based on time to market, We have as you can see over specified the PCB by quite some way, our ASIC will only consume an absolute maximum of 250 watts and we know the PCB can cope with 320  watts. This is the level of design margins we employ.
 
So you can use the following to see how safe our design is.

• We have used a VERY large package for our die, not because our die is large, but to make sure we can handle the power and heat requirements.
• We have used more DC/DC modules than strictly necessary
• We have used the most pessimistic/conservative estimates in all of our simulations. Including but not limited to Yield, Performance, Power and Heat  
• For example while testing each part of the chain. We have tested our onboard Linux device to make sure it can handle up to 1.2TH ( The controller board also has and expansion for additional linux devices for future upgrade/ second generation)

Meanwhile, at least 650TH of new capacity is added to the Bitcoin network every single day.

MPP in June/July is like performing CPR on a patient that died many weeks ago.

Please don't compare hashfast to legit companies(excluding bfl)

Those companies all are able to produce and ship hundreds of machines a day.

Hashfast has averaged a whopping 6 units per day the past 3 months.

And the whole time they were sitting on their asses not shipping, they were creating next gen boards and a new production line which will not be used to give existing customers their hardware.

As someone who has been in hardware development for many years, EVERY bitcoin ASIC vendor has mainly had issues with the Board design, and Thermals/Mechanicals.

Once the chip design is done, its real easy to call the Chip FAB up and ask for chips...

HashFast - Original board VS Yoli 70% more performance with just a board change
KNC -  Ran out of VR modules because they bought an off the shelf part.  Then had Capacitors catch fire probably due to not spec for enough ripple current.
BFL-  Yea... Everything.  missed their power budget by 5x 
Cointerra-  Very complex board with heavy components on the backside.  cant be build fast.   Their issues are probably signal integrity and power related which explains the way less than 2Th.
Avalon-  Dont even want to talk about their problems.   Im still pissed.

ALL of these companies Im sure have trays of chips sitting on shelves doing nothing.     Their issues are that they cant build boards fast enough, or they dont know how to properly design a power regulator, or they cant cool the chip they designed.


-Smily

Actually it is worst than that, they are selling Golden Nonce ASIC chips mostly funded by their B1 (MPP), B2, B3, B4 customers to MrTeal and gateway (remember this http://eligius.st/~gateway/news/quick-visit-hashfast-hq) so they can afford to pay their lawyers to fight against these same customers.  What Irony?  Is MrTeal really that ignorant and actually believe what HashFast said is true (no delay to existing customers) or blinded by $$$ = don't give a damn?  I wonder if these same lawyers will go after whoever receives Golden Nonce chips before all prepaid customers receive their products?

Probably. Then there's cointerra...and amc/vmc. Actually someone should just shut down all the scammy american manufacturers. None of em are worth crap.

Interesting... very interesting. I wonder if the same could be applied to BFL.
