Topic: HashFast announces specs for new ASIC: 400GH/s - page 534. (Read 880479 times)

Your site says "Shipments anticipated to begin: November 30, in order of purchase"

So if we ordered a batch 1 babyjet, will the upgraded babyjet ship before November 30th?

Unfortunately, at that price, we cannot offer the Miner Protection Program.

For overclocking will it be supported out of the box or will it require alot of tinkering?

Also on your recent blog posts you mention a sierra batch1 but on your site there is only batch 2. Did I miss a batch one of Sierra going out in October?

Our Golden Nonce ASIC is specifically designed to be overclocked. It has on die thermal controls so that the controller can sense and adapt to local conditions. If our customers are able to offer improved cooling for the chips (through a lower room temperature, for example), the controller will be able to run the chip faster. We are going to make all of the software open source to allow customers to further tweak its operation. We believe both of these aspects are specific advantages of our product over our competition.

The batch number refers to the batch of ASICs coming out of TSMC.

Does this upgrade include MPP, would we get up to 4x the 800GH/s ?

Hello,

We aren't planning on having a prototype. Our actual, working Batch 1 Baby Jets are anticipated to ship the last week of October.

Please feel free to PM me or send an email to [email protected] with any additional questions.

Thanks,
Erin

Hello,

I responded directly to your #449 case.

Thanks!
Erin

We have just launched this new product - for customers that previously purchased a Baby Jet from us prior to the current sale.

It looks like it'll be supported out of box.

From what they've said, the colder the room/area, the higher the achievable clock speed as the GN chip is supposed to throttle back to protect itself from thermal shutdown.
Good thing my cooperative's 2 host sites for our 2 HashFast Baby Jet and 2 Sierras have lots of A/C to spare.


500GH/s & 1500GH/s are my OC targets for both Miner types via incremental step ups of voltage/clock speed, and close monitoring of fan speeds, system temps, & CPU temps.

BTW, I have 75 shares available for a non-MPP Sierra at $69/share if anyone's interested. This should give you 12-15GH/s a share to be delivered Dec 1 (est.).

Per my phone call with John S. this morning, I even secured this pricing out thru Friday, instead of tonight's Flash Sale deadline, since I'm doing deposits on both tonight. It's the 4th GB link in my sig. AFAIK, our thread is the only place you'll still be able to get Flash Sale pricing after tonight if you're interested in partial ownership of a Sierra.

I would be quite interested to see your ROI calculations. From recent ones I have done I would loose around 4btc


agreed, Personally I think it would be nice if they told people ahead of time by a little. Even if they just say a day before that tommarow we will be opening up so and so.

If the "first batch baby jet special offer" is a second chip to have on the baby jet (since that the motherboard can house 2), for a price of like 1/4th of the baby jet price, i would like to know it now, since that i suppose i will need to pay in like 1 day if this offer comes out.

So, if i need to send a significative amount of money to the bitcoin ecosystem, i would like to know it in advance.

(if someone from hashfast wants to reply to this privately, my ticket number is 449. Thanks.)

Especially since that it's the same hardware used with batch 2 baby jets... Anyway, i'm still confident.

this is a great solution.  this makes me very happy as it will fit nicely into the solo mining configuration i currently have set up.

i'm looking forward to harnessing the power of 10 BJ's.  maybe 50 if and when MPP kicks in.

We have just released a series of blog posts written by Simon here:  https://hashfast.com/blog/

Enjoy!

the problem is, they are not getting rich right now off of anyone.

everything they're bringing in they are plowing back into making this a reality, ie, the best miner available in the market.  like i've said many times before, i am very excited about the design of the BJ and Sierra.  using OEM parts and being modular, i expect my own large order of BJ's to make an acceptable ROI for quite a while.

Come on guys, really? There must be a new get-rich-quick bestseller around.

Agree - it certainly is an ambitious schedule.  We have put a *lot* of thought into every way to optimize it, multi-source components and suppliers, have contingency plans in place for delays/surprises at any point, etc.  Still, you are absolutely right - it is an operationally complex process under very tight timelines.

1) Yes, we do. 
Our chip was taped-out to TSMC last month, as described in the joint press release we, Uniquify and TSMC put out about this.  Prior to tape-out it passed all our physical and logical tests, and following that it passed all the design rule verification rules etc. that are part of the tape-in process.  Currently it is under fabrication - we past design, well into manufacturing, and are exposing more mask layers every day or two.   We get daily updates about it's progress, and track against them.

2) Complete silicon wafers will come out of TSMC in roughly 4 weeks. We would love to be able to release a *lot* more information about this, but we do need to be mindful of our NDA
What we can + will do is to post a basic explanation of the fabrication progress, how we track against it, etc. in the next few days.  Unfortunately this will be far higher level and will -not- have anywhere near the level of granularity we have;  we would **love** to do just that, and replace the noise about we are seeing in the market about hopes + aspirations with straightforward factual information, but our NDA with TSMC prevents us from doing just that.

3) Initial PCB design is complete (including both Gerbers and parts/sourcing selection)
We are currently finalizing it, optimizing for fabrication.

4A) Assembly service selection is completed.   The steps are as follows;

- First wafers coming out of TSMC will be hand carried by from the TSMC to our substrate manufacturers
  I'll see if I can get a picture of the airline-approved wafer carrying case we will use

- Chip substrate and packaging
  We have contracted 2 separate companies (one low volume/very fast turnaround, the other huge volume/longer ramp-up)
  Either one is capable of producing sufficient volume to package all chips sold to date 

- PCB and power stage assembly
  We have contracted a US-based specialized company for production of PCBs+low power stages for all chips sold to date.

- Final Assembly
  We have contracted a specialize company to assemble the modules into working Baby Jets and Sierras, and ship them to our customer
   via Fedex as soon as they are completed, following our published order # list.

4B) BOM complete, down to individual screws and stand-offs.
Components ordering well underway - that and shipping/logistics is the primary focus of our operations team right now

Also, prototype machines using precisely the same components as the final machines complete, assembled, and tested.

Re: testing, this includes completing stage III thermal performance tests; stage 1 was chip thermal emulation during the physical design stage of chip development, stage 2 was software thermal emulation of the finished machine, and stage III is inserting a controlable heating element of the same form factor as the chip package into a complete gold prototype, and measure how much heat the system can dissipate while remaining within operating temperatures.

The results of that test were very positive; the design goal for our GN chip was a cooling system able to dissipate 250W, at which level it will produce 400 GHash/s.  The stage 3 test confirmed that the cooling system is able to dissipate significantly over 300W, which we believe will lead to significantly improved performance 

5) Our chip has been running CGminer (and mining) for months now as an FPGA.
We have created high-quality drivers for the chip.   We expect to have 3rd party confirmation of that fact out very shortly 

6) We are not designing a custom case.  Other than our chip and PCB/power stage we have not designed any other components, and intentionally so;  the only way a system of this nature can be produced in this kind of time frame is to use existing standards-based parts as far as humanly possible.  The goal is focus, focus, focus.

7) Correct.

Sounds a lot like BFL to me...

Well, I mailed them and got this reply:


It seems to refer to the special promotion you mentioned in an earlier message. At least they didn't ask for 10% to trade the order.

How soon until you guys have a working, hashing unit ? I'm interested in purchasing one of your 2TH/s units, but would like to hold off until a working prototype is documented.

Cheers.
