Speculatively Translated:

We have a retention problem. People aren't willing to wait until the order queue is fully processed. So they are "bailing on us" for other companies with better offers and forcibly pulling money out of our bank accounts.

We couldn't figure out a way to keep them waiting in line and leaving with their money. We are letting people with spots closer to being serviced in the backlog to sell off their order numbers for some monetary sum. Which means we will keep our newer customers and give "added" value to those who no longer want their orders. (thereby circumventing the forced refund process)

So go along with us. We need this cash. We need to keep our newer customers and our cash flow is probably running real low.

Transfer your unwanted position in line for some cash and keep us solvent, pretty please!

(This is my personal interpretation behind the bullshit.)

Sounds painfully correct. Their progress has been incredibly slow, with them moving on a single product (Jalapeno) at an accelerated rate not remotely linear with a different product (singles). It could take them until late october to catch up to July orders, and possibly some time in december before they catch up the last pre-order.

In my opinion, they are simply using new "orders"/pre-orders to keep up with producing orders from 7-12 months earlier.

The crew and I took a well needed weekend off - we've all been working non stop for 3 weeks straight.  Back to it Monday...

Please don't be offended by this, but I still have an august order for a starter kit #13X that hasn't budged. I REALLY hoped that it would be tested, packed, and shipped (or at least by the door to ship) by the end of the weekend.

Its going to be September 9th at the earliest when my unit ships, which is nearly 2 weeks later than hoped in the 'by the end of august' shipping estimates. This is tremendously faster than BFL has/will manage, but slightly disspointing as every day that goes by is a significant reduction of its lifetime income.

Many thanks for your work so far, and I am sure that a lot of other orders >#100 feel the same way, particularly if the remaining units are "testing" all weekend long into the 100TH pool

BitFury and punin did a great job. They are heroes in the bitcoin community.

The bet is long over. Just confirming that a UNIT is whatever fits on a single M-board connected to a Raspberry-Pi.

And of course I have integrity. If I didn't, I would have created a second account to ask the question.  I have nothing to hide.

your account has 16 posts, most of which focus on arguing/asking what consitutes a bitfury 'UNIT', which directly relates to a bitbet you lost.
(the bet was that bitfury would deliver on their promise to deliver units at 400Ghash and under 400w, by the end of august - They did, albeit adding a little extra hardware to compensate a rushed manufacturing process that wont occur again
3684  Economy / Gambling / Re: BitBet incorrectly declares yes to a no bet. Stay Away from BitBet!! on: September 07, 2013, 05:06:58 PM
This bet is a big NO NO!
The unit did not meet requirements.
Unit is a standalone miner, which hashes max 365 GH/s not 400 GH/s as stated in bet
If they would produce M boards with 17 slots they would meet the requirements.
Otherwise bet is a NO resolution.
You can't actually buy something from punin which will hash more than 365 GH/s... DUCY?

The cards underpreform due to manufacturing methods, not the chips or design. the next batch is expected to work perfectly, and some cards in this batch CAN run >25ghash each, ohers can't

They met all customer promises: they shipped >400GHash to a customer who ordered it, even if a few extra boards were needed to do so. (BFL is shipping thier 'Units' one at a time, several weeks/months apart)

This thread reeks of 'sore-loser', and in my mind the company delivered on every promise: minimum hashrate for an ordered product, maximum power consumption, and delivering in the month of august. (which i might add is the most important factor of the bet IMO). They delivered on time and every customer is satisfied (save for a few technical errors in rare cases). Focusing on the definition of a 'Unit' is pulling at hairs

I guess MBP is really busy, I'm trying to get through to make an order for October.  Anyone trying to do the same?

Better hurry - there are only 35 October hashing cards left...

34 Smiley

sounds like EMI interference along the lines. This may be a good reference/example of the issue:  http://www.overclock.net/t/1424387/gallery-build-log-ultimate-wall-mount-rig-maxxplanck-v2-completed

Guy build a dead-sexy wall-mounted coputer system and used pci extension cables. basic cables caused his GPUs to not turn on. aluminum foil-shielded cables enabled the cards to run, but disconnect under 3D applications. He resorted to professional shielded cables for a working result

try wrapping it in aluminum, or using a shorter cable. Your image shows that it folds over itself a bit because it is ~4inches too long, and this could be enough to cause interference
3687  Bitcoin / Mining support / Re: **US** BitFury Setup Guide on: September 07, 2013, 10:09:00 AM
have a board with only first 4 chips hashing. I think the chips start from bottom left corner and go vertically up (U40, U41, U42, U43) down (U44, U45, U46, U47) ,..., then down the second column and then up, etc. Any tips on how to make the board fully functional. It's okay if chip 5 will not hash.

Okay problem solved. Inferring that the problem chips be disabled as per cscape's suggestion
I cut the SPI traces of 4th and 5th chips using a knife and shorted the jumpers using thin copper wire. Here are the results. The board now uses 14chips for hashing.


https://i.imgur.com/v3HhER8.jpg

I fixed an EOL board by shorting the solder jumpers. no need to cut the traces. Funny, my EOL board with disabled chip is hashing at 25GH/s Smiley

How were you able to tell which chips were bad?

Where's the reference to how to fix the problem?

Thanks.


The number of chips that chainminer detects stops at a certain number. that is the last good chip. solder the SJ pads next to the first bad chip (these are the pads connected via traces from the chips).


BTW what was the initial hashrate of your EOL board?

It was around 15GH/s before.

looks like you 'destroyed' the connections for 2 chips in your board between chip and resistor set. Is that the effective way to disable the chip? Does it still take power when the board hashes?
3688  Bitcoin / Hardware / Re: [ANN] US/North American Bitfury sales now open ***full prototype pics*** on: September 07, 2013, 09:56:55 AM
So have all August orders been shipped? Or what % have not been shipped?

If we order for October now, what is the likely date we have the unit in hand?
up to order ~98 have shipped. No news from anyone higher than that (#13X still 'CC paid')
3689  Bitcoin / Hardware / Re: [ANN] US/North American Bitfury sales now open ***full prototype pics*** on: September 07, 2013, 12:49:29 AM
#98 received in Canada today, Fedex overnight.

Mounts nicely in the Rich C open case. Hashing 26-27 GH/s so far. Going to order a GPIO extension cable to allow mounting the RPi on the case frame.

Dave and crew, many thanks for delivering a great product!!

https://i.imgur.com/OpRNNOR.jpg

gorgeous case! how much was shipping to canada? i might get one for my starter.

on a similar note, how are people placing/mounting these? Are they safe and stable on a flat surface, or do they need risers and/or non-conducting surfaces? I plan to put it in a corner of the room where it wont be disturbed, but i want to be 100% sure bumping the table or poking around the unit wont topple the miner onto the floor
3690  Bitcoin / Hardware / Re: [ANN] US/North American Bitfury sales now open ***full prototype pics*** on: September 07, 2013, 12:42:11 AM
Maybe your calculator is doing something foolish, like the genisis version does.  Difficulty in the trillions early next year?  Not likely...

When the Bitfury rigs no longer make money, nothing on the market or anticipated to be on the market this year will, either.  They are as efficient as some of the up and coming 28 NM chips...

That the calcator I'm using.  So what you are saying is that a hashrate that high isn't realistic. What are you predictions then for a return on a 400 gh/s unit.

I think past ~december, the monthly increase (currently around 76%), will taper towards 50%, and by ~february/march should be a lot more reasonable, maybe 35%.

right now, GPUs are pretty much all stopped mining bitcoins
soon, FPGA will follow (~45w/Ghash) at $0.10/kwh, these are only making about $0.35/Ghash/day right now, and in another 2 months will be costing more electricity than making BTC
next, avalon will stop (~10w/Ghash
then, asicminer will stop (~8w/Ghash)
then BFL (~6w/Ghash)

bitfury is operating at <1w/Ghash, which puts it in line with 2nd gen ASIC designs, and enables them to mine at a profit for MONTHS (years?) longer than the above competitiors, which currently account for most of the network

1% fees on give-me-coins.com Smiley
plus a 1btc bonus for the first 4 blocks found on pool and no pool fees for life on all there pools

too bad they only have a hashrate of <1TH, could take weeks to find a block...
3692  Bitcoin / Hardware / Re: YES, you can get a REFUND from BFL on: September 06, 2013, 11:21:31 PM
so here is my process so far for refunding a 5Ghash jalapeno purchase:

1) contact BFL for refund - no response after 3 days
2) paypal dispute (after 45days)
3) paypal dispute closed automatically (after 45 day limit)
4) call paypal:
- operator cannot refund after 45 days
- acknowledges that BF Labs Inc. has other complainants and agrees to make a note of my case in their file
- suggests calling my bank to do a cancel/chargeback
5) call bank:
- paypal was a 'preauthorised debit', meaning they cannot reverse after 24hrs
- suggest calling paypal again to resolve the issue
6) call paypal:
-new agent
-explained to her all of the above
- indicates that BF Labs has an 'account manager' (apparently a lot of large paypal sellers have one), and will email my case to that person
----> implied that the account manager has the ability to refund payments and may be able to assist my case
- I am told that I should receive a response from paypal either later today or monday/tuesday after the weekend


I guess we will see what happens. I only paid $332 CAD for my unit, so even if i get no money back and get my product in "two weeks", it is not a terrible loss, but I dont see how I could possibly receive the unit before mid-october, and thats about the time when bitfury will start shipping its $500/25Ghash pre-orders that would be a far better utility of my money

3693  Bitcoin / Hardware / Re: [ANN] US/North American Bitfury sales now open ***full prototype pics*** on: September 06, 2013, 07:38:05 PM
How are you guys adding in the extra load (without drawing much power) for your power supply so that it will stay on?

Is there a minimum for a PSU to stay on? I have seen someone else post about this a while ago but have not tested it yet. My PSU kicks on fine with only 5 watts on it, but I haven't tested it for long durations.

I have a 730W psu running about 30-40W (modminer FPGA) over only the 12V line, with the always-on hack and its run continuously for about a week no issues

extra load? a modern PSU should run safely with minimal load, you just need to bridge the mobo sensor pin to ground to force it to stay on
3695  Bitcoin / Hardware / Re: [ANN] US/North American Bitfury sales now open ***full prototype pics*** on: September 06, 2013, 06:10:28 PM
Maybe they won't last 10 years....  Maybe only 7....   The useful lifetime of these boards is measured in months at this point...

OC FTW !

My thoughts exactly.  I'm hoping for 12 months, but I am most definitely an optimist.  If there was a way to OC, I'd be all over that.  Wink
There is, by replacing the regulator. Atleast one person so far has done this and has reported about 10% gains from it. It does void the warranty and does require a skilled professional to do, but is possible.

link? I was under the impression that if a board has <16 working chips, it may be possible to overclock the others using the additional headroom provided by not running a chip (ie: 2/16 chips dont work -> 12.5% more power available to working chips. (am i correct on this, can anyone confirm?)
3696  Economy / Service Announcements / Re: [ANN] Bitfury ASIC sales in EU and Europe on: September 05, 2013, 08:21:54 PM
How can you say Slush doesn't still care?   I prepaid for a Trezor months ago.  Oh, well,  I mean, when I mine on his pool we only get a couple of invalids or bad block reward calculations per day....   Usually...  When the servers aren't down...   Maybe he just lost his BitcoinTalk password ??

Errrrrrmm.   Never mind...

so is this to say i *should not* use slush's pool? I am using it now for an FPGA with no issues, but obviously i will want to squeeze every drop from my bitfury
3697  Bitcoin / Hardware / Re: [ANN] US/North American Bitfury sales now open ***full prototype pics*** on: September 05, 2013, 01:50:31 AM
#13X still sitting at CC paid, i will be a little dissapointed if it doesnt update tonight. Punin shipped pretty much every single on of his orders within 2 days, and dave has had the entire set of m and h boards since friday
3698  Bitcoin / Hardware / Re: [ANN] US/North American Bitfury sales now open ***full prototype pics*** on: September 05, 2013, 12:14:33 AM
I hope Dave breaks radio silence soon - I'm actually starting to feel a little disappointed that my order has been in a "ready to ship" state for two days now...

The silence does seem like we might be in for some bad news...it certainly seems unusual. Hopefully everything is ok.

this time yesterday we saw orders up to 87 or so change status, but nothing today... odd and a little dissapointing
3699  Economy / Computer hardware / Re: [WTB] 2-5 USB Block Erupters : Ontario, Canada on: September 04, 2013, 02:42:32 AM
still no other offers? I would love to grab these before its too late, and if you want to sell your asic for the best price its ever going to fetch (i wouldnt be surprised to see groupuy prices drop to 0.12BTC amid the difficulty bump and BTC rate increase)

#13X starter kit, flat fee : no news yet

This is sounding good though! I just hope flat fee shipping can beat the weekend!

NOTE TO DAVE: is there a mid-tier shipping level to Canada that will take less than 4 business days? I would hate it if the flat fee takes more mining profit away from a starter kit then I could mine over 6-7 days

  I dont think you can get any faster with custom road check.

Priority Mail Express International™ Flat Rate BoxesMore info about Priority Mail Express International™ Flat Rate Boxes
USPS-Produced Box: 13-5/8" x 11-7/8" x 3-3/8" or 11" x 8-1/2" x 5-1/2"
Maximum weight 20 pounds.
3 - 5 business days   
$64.95

Is this the flat-fee shipping, because it is much less than the $199 offering on the site that indicates it will ship with express international packaging? I know there is no intended harm in the high price, but I just fear the idea that my miner may ship with a low-tier priority when I would gladly pay $65 to get it 2-3 days faster
