This is the official thread for support, questions, applause and blames related to our CoinCraft series of miners and ASICs.

News and updates will be posted here, if you have any question feel free to ask!

Thanks,

The bitmine.ch team



NEWS

Software update for the CoinCraft Desk Units has been released and is available, together with instructions, on the following page:


http://www.bitmine.ch/?page_id=5483



This is the changelog for the latest version:

*) Fixed OpenSSL heartbleed vulnerability

*) Fixed web interface issues with Apple iOS-based safari browser

*) Fixed an issue with recent generations of One-Wire temperature sensors

*) Added thermal shutdown and automatic recovery

*) Added over/down-voltage ability both with basic preset settings and advanced settings, leading to an increased hashing rate.

*) Updated cgminer to latest version 4.3.0

*) Optimized cgminer’s driver with up to 20% less CPU usage on Raspberry Pi system

*) Stepped back to diff-1 jobs so that HW errors will be detected earlier and the displayed hashing rate will be more consistent with the effective hashing rate


Enjoy!

How about you deliver on your existing products before launching another pre-order vaporware

Order number #11xx? Really? After 30 minutes? I hope your counting begins at #1000. Wink

Have a nice day! Smiley

1. Can I choose Reservation queue today and then pay in 2-3 weeks and jump into the shipment queue?
2. Are you going to sell separate hashing cards? If so when?
3. Are the hashing cards for Coincraft Rig and Coincraft Desk compatibile?

I still do not get the Reserve queue, It is not working for !!! is it working for anybody here? It is really a nice feature if they honor their promises.

the better thing would be paying 10-25% of the order to show the interest and to secure both parties, then when they start mass production and have a better picture about shipping schedule they could ask for the rest of payment. it assures both your place in queue and funds for their production plan....

No, but I believe that's only a bug.

Hi -

can you tell us any additional info that lets us know who you are, who the asic designers are, so we can become more comfortable with you and your team etc?

Have you taped-out already?  when was it?  and if you havnt, presumably it must be imminent to be able to deliver by end of november?

How are you financing the NRE's etc?  are you assuming the pre-orders will cover it?

You say on your web site that you have absolutely the best 28nm asic out there, yet your specs dont seem to establish those credentials so can you share how you are 'better' than your competitors?

Your power consumption per GH  - while good at 0.6 w/gh, is no better than the three most recently announced 28nm entrants (hashfast, cointerra, and bfl) and it could be argued that  hashfast and cointerra are claiming theirs chips will use LESS than 0.6W/GH at nominal volt/clock, and you're not saying it will be less, but are saying it will exactly be 0.6W/GH, which makes it sound like your silicon is close but not as low power as theirs.  And then youre saying if you undervolt/underclock it then it will have lower power, but that is completely true for any chip ever made, and all the others could claim that as well.

How are you cooling your chips?  if youre going to be substantially overclocking them, like you say on your web site then you must have some pretty serious cooling plans.  can you share those?

does coincraft desk and coincraft rig use the same 28nm technology, I fail to understand the deference between these two.

Quote
Coincraft Desk is the product of natural evolution from our Generation 1 devices based on older Avalon’s chip

what deffer between the two designs ?

Quote
Available in 28nm technology from 500 GH/s to 2 TH/s in 150 GH/s increments.

they didn't mention this on the coincraft desk!! what chips they will use on that one ?

you can reserve a place in queue without paying if you are not comfortable with trusting them, they will ask for full payment when they are ready for mass production and shippment, which seems to me really fear, at least this is what I've understood.....

Giorgio, any info regarding:

Quote from: Bitmine FAQ
Q: Do you offer a trade-in program for previous generation devices?

A: Yes, for all the customers that have bought from us a previous generation device, there will always be a trade-in promotion that will allow you to upgrade to newer generations. Details will be published along with the commercial details of each new product.

Delivery schedule, please.

Your exact shipping date is determined based on the position in the shipping queue, it is widely explained in the website please take a look there for more information!

Yes, now that we have finished running to set-up everything for the 28nm sales we will post the details of our upgrade program in the next few days!

Have you taped-out already?  when was it?  and if you havnt, presumably it must be imminent to be able to deliver by end of november?

These are widely covered in our FAQ and in our website, please read it there you will find all the needed details.

How are you financing the NRE's etc?  are you assuming the pre-orders will cover it?
No, we are already financed, that is also explained in the news!

You say on your web site that you have absolutely the best 28nm asic out there, yet your specs dont seem to establish those credentials so can you share how you are 'better' than your competitors?
Pretty easy, our estimations are conservative, not optimistic. We didn't put a lot of efforts in marketing, but we did put a lot of efforts in development  Smiley

Your power consumption per GH  - while good at 0.6 w/gh, is no better than the three most recently announced 28nm entrants (hashfast, cointerra, and bfl) and it could be argued that  hashfast and cointerra are claiming theirs chips will use LESS than 0.6W/GH at nominal volt/clock, and you're not saying it will be less, but are saying it will exactly be 0.6W/GH, which makes it sound like your silicon is close but not as low power as theirs.  And then youre saying if you undervolt/underclock it then it will have lower power, but that is completely true for any chip ever made, and all the others could claim that as well.
This is at our nominal power usage, if you need better power consumption, you can go in powersave mode and go 0.35 J/GH which is, as far as we know, industry leading. Our low power mode makes use of very low voltage transistors and is optimized for that, this is very different than just undervolting/underclocking the chip!


How are you cooling your chips?  if youre going to be substantially overclocking them, like you say on your web site then you must have some pretty serious cooling plans.  can you share those?
Aircooling up to Turbo mode, no need for expensive watercooling sets like some other competitors! These are expensive, prone to mechanical failures and bulky.

You are already protected by our Customer Protection Plan and, if you don't want to pay anything upfront, you can still place an order on the reservation queue where no payment is required at all (just few days before the shipping of your order).
