Hi!
Accept a bank transfer Knc Jupiter?
Yes, if you are buying as a registered company. If you are buying as private, I'd need to verify your ID (been paid from hacked bank accounts in the past which caused me lots of trouble). Invoice ? Tax ?
I have a registered company and could sell B2B. Tax payment in your country would then be your issue. B2B of course, but the 22BTC / Jupiter ist brutto (incl. switzerland tax) or netto ? 22BTC includes 8% Swiss VAT. |

was ist passiert ? wieso werden die miner verkauft ?  FYI, per PM geantwortet: Steige nicht aus, habe meine Stromkapazität erreicht und kann z.B. die Blades nicht mehr betreiben, weil sonst Strom für die Jupiter fehlt. Ausserdem bereite ich mich auf den Wechsel zu Bitmine's Rig Ende Jahr vor, d.h. ich kann dan mit der gleichen Stromkapazität mehr GHps erreichen.

iam interested in the Jupiter, PSUs inclueded ? Rabatt for taking all ?
PSUs not included. I am operating them with CoolerMaster V700 which I paid like 150CHF each and would be ok to re-sell for 120CHF. If you take all 20 Jupiters, you get one more for free (I actually have 22 of them). |

Update (2013-11-11): Sale closed
All available rig sold.
Update (2013-11-10): Sale temporary halted
With pending orders for almost all remaining boards the sale us currently halted until the backlog is fully processed. Thanks for your interest.
Folks and miners, over time I built up a large mining farm of 30TH, which I am partially offering for sale as follows: 280 214 108 Asicminer BE blades V1
- 0.5 BTC each
- 3.2 BTC for 8
- if you buy a half rack of 32, you get 3x Enterpoint power distribution boards and power cords for free
- if you buy a full rack of 64, on top of that you get the special hand-crafted customized Ikea GORM wine-shelf for free
128 112 108 bitburner Fury
- 3 BTC each
- 21 BTC for a 8-board stack (CAN-bus connected, needs only one USB port)
20 KnC Jupiter all sold to user Menig
I took some photos of the rig and placed here. As you can see from the pics, this is a hefty amount of boards which I am not going to pack and ship, but you will have to drive to Switzerland near Rapperswil (SG) and pick everything up. If you happen to buy a full rack, you'll need to come over with a transporter. I assume those interested know what they are buying and therefore withstand from posting the specs and PR. If you have any questions, please PM me.

What does "git describe" show? There was a bugfix recently for this very issue.
Just checking over past 2 hours with fresh build of Will report back if problem still occurs. Thanks for feedback. |

I started operating a larger number of bitburner Furys over the weekend (48 boards x 16 chips) and am constantly running into some hang condition with latest cgminer (git master). After some hours of operation mining stops and cgminer obviously is blocked in an infinite loop. The related output is: [2013-11-03 02:39:15] Accepted 3f0e2f2a Diff 1.04K/1024 BBF 2 pool 0
[2013-11-03 02:39:16] Network diff set to 391M
[2013-11-03 02:39:16] New block detected on network before longpoll
[2013-11-03 02:39:16] Stratum from pool 0 requested work restart
[2013-11-03 02:39:17] BBF3: Idled 1 miners
[2013-11-03 02:39:17] BBF1: Idled 1 miners
[2013-11-03 02:39:18] BBF2: Idled 1 miners
[2013-11-03 02:39:18] BBF4: Idled 1 miners
[2013-11-03 02:39:18] BBF0: Idled 1 miners
[2013-11-03 02:39:19] BBF5: Idled 1 miners
[2013-11-03 02:39:26] Waiting for work to be available from pools.
And there it remains until I quit and restart cgminer, where mining starts immediately again. From the source code I see the hang occurs in the first while-loop in hash_pop(), but I don't quite understand why this happens. Any suggestions how to track down the problem? Thanks. |

Folks, those of your considerations on chip price and their ROI potential are all valid points, but really: aren't they better placed in the mining speculation sub-forum? Let us please focus on the technical aspects here. If you don't see a potential for profitable mining rig based on this chip, by all means do not spent time or resources bothering and move on. I am forwarding the feedback collected here to Bitmine and hope we will have an updated preliminary spec document available soon. I will also ask to put it on github, which at this state is only to keep the word given, since in its sole binary form it is not of much use being put into an SCM. I have a question about the RESP_BIT. It seems it's only used for the 0x08 command. [...] Please clarify  This is also some leftover from moving from a queue based work processing to the now proposed descriptor based with 4 individual work items per chip. Before, the idea was to signal the availability of results from chips within a chain by setting the RESP_BIT as long as there are results available in the output queue. With that, we would have to provide the winning nonce and some reliable ID to assign the nonce to the work items queued at host. This typically would be some hash of at least 32bit length to reduce risk of collisions. With that, we would need to provide 2x 32bit data with each READ_RESULT command. The new approach is meant to reduce the data by those 32 bits required for the ID and with that communication delay. The JOB_ID fits into the command's spare bits, which moves the correct assignment of the winning nonce to cached jobs to the host. So, to clarify: there is no RESP_BIT anymore, but 3 bits holding the JOB_ID for the returned result. If it is 0, there are no results available in this chain, otherwise the response provides winning nonce, JOB_ID and chip address. A pseudo code sequence to process work and results would roughly look like this: reset_chip_chain();
for (int chip = 0; chip < chip_chain_length; chip++) {
for (int job = 0; job < 4; job++)
set_work(chip, job);
}
while (1) {
sleep_time = 2^32 / (chip_speed_in_hashes_per_second * chip_chain_length);
sleep(sleep_time);
while (1) {
result = get_result_broadcast();
if (result.job_id == 0)
break;
send_result(result);
set_work(result.chip_address, result.job_id)
}
}

Thanks, but that's the one that's been out for a few days, and doesn't have much if any useful information in it (no electrical, no power pinouts, etc, etc). Giorgio & Zephir have both said that the spec will be put on github, and G said it would be updated today... that's what I was looking for.
Yes, it will be put on github with any other support material as soon as it is available in a post pre-alpha state. Also true: the preliminary spec is exactly that and meant mostly to present the chip front-end and resulting host interface for a broader review. Bitmine is currently working on the first revision of the draft that will be updated ASAP. Since the chip is designed externally (Innosilicon), it takes its time to communicate and settle the final numbers. Generally, since the Coincraft A1 will be at DIY folks' desks not before late December, there is no need to be impatient. If the provided documentation does not suffice the developer's demands to work on board designs, a full refund will be granted. Furthermore, given the prolonged availability window (valid till chips are in my hands), there is no need to rush into ordering. Take your time to study the documentation and specs when they are released in their final state, and order only after you decide to work on an own design. Also in this context, please understand that this offer is really meant for DIY folks only, i.e. not for those who want to buy chips and then send them to some 3rd party for assembly. In that case, you should talk to the developer of your choice directly, since with enough interests they can order from Bitmine and get better volume prices. Obviously I do not want to distract people from buying chips, but I want to prevent the chaos the Avalon chip distribution ended for some buyers (ordering chips here and boards there, ending up nowhere).

I would like more than one opinion.
Who needs opinions when you can have math? [...] While looking at profitability only from the cost perspective is perfectly fine for the home user, in larger scale mining the available power is most often the limiting factor. Say you operate a mining farm that has 16kW available and want to fill it up with Bitmine 40-chip units. Would you prefer running 10 units in turbo mode, or 26 units in nominal mode - 16THps vs. 26THps? It is not all that black and white if you start considering those factors. |

Zefir, I sent you a PM a while ago.
Can you please check and reply?
Thanks
Sorry, slipped through. PM'd you. ... are some avalon chips available ?
Yes, there are around 350 left that I am offering for 0.03BTC/chip. Please PM me if interested. |

Anyone an idea what the pin numbering is on this chip?
intron
Maybe not quite irrelevant and added to TODO list: TODOs for Coincraft A1 preliminary datasheet v0.1.A
* remove last paragraph in 4.6.
* provide pin numbering

Any news from ASICME.com chips delivery?  Yes: see tracking. That was an odyssey  Parcel left Frankfurt on September 25th and was then gone from all radars for 10 days. DHL claims it was in customs, but they were not able to locate it correctly during that time. I was prepared for the worst, glad it made its way. To those who are waiting for the escrowed funds from ASICME.COM: John was already informed and will soon start releasing coins (if not already done). |

How did you dig that out? That's not including the latest review results and most probably will be removed from that location soon, but ok: there it is Maybe they uploaded a wrong one Link is on this site: https://bitmine.ch/?page_id=863Ah, no - my mistake then. I looked at only one location I knew I fixed and noticed it is still there, that's why I assumed it is an outdated version. Nevertheless, as the water mark indicates, this is WIP and will be updated based on the community's feedback. One thing I noticed immediately is a leftover from previous versions in section 4.6. Write the job to individual chip and start the computation. First the input interface was planned to have a queue of two work items, but was then modified to have a descriptor ring for 4 entries. So don't get confused by the last paragraph in this section and just ignore it. If you find other issues or want to provide feedback, feel free to post it here or contact me via PM. I will collect and forward everything to Bitmine and help to establish the best chip frontend interface around Happy DIY designing! |

For the sample chips, do you already have them in hand?
I didn't see a direct answer, what is the exact specification of the packaging? Number of pins and package type?
Is it not clear from the OP? The chips offered here are the sample chips, i.e. those from the pilot run. So whether you order 2 chips to validate your design or 50 to build your first boards - those are the very first chips available. Yes, but are they available today? I was thinking about ordering a few chips to build a board. But not going to bother with it unless you have them in hand at this moment. The way it's stated makes it seem as if they're available today, but without even information about what package type, number of pins, and pin out of the chip, makes it seem like they're not available today. No, if you look from that perspective, there will be no sample chips but only an all-or-nothing first shot with enough wafers produced in the pilot run (like KnC did and succeeded). If there is a risk of chips not working as expected, it is covered by the CPP. The preliminary datasheet will be released to the public by tomorrow, I'll post a related link here as soon as it is online. |

Is the 19th still a hard deadline?
The deadline was set to leave me enough time to negotiate assembly contracts for the unsold chips. After clarifying with Bitmine, this can be done quite ad-hoc and does not need to be decided beforehand. Therefore, the deadline is extended to past the delivery date (OP was modified accordingly). As for the documentation: I am currently reviewing the datasheet draft for the A1, which will be made available to the public before October 15th. |
