#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.

I hope not! well marked packages usually breeze through

Are the boards fully payed. Do you keep the funds in btc or are they payed/converted. How much can we get refunded.

I asked him personally ;

Code:
Hi,
It's a bit late as i have paid for the components already..

this is the answer i guess all things are paid!

even so, avalon chips are almost 70% of the cost. In any case an update would be nice, though the blame is clearly on avalon

Hi guys -

More tomorrow.

thanks for the update! Will starter kits be seeing 35-40ghash total like the punin customers? Also, can you add any info for the basic shipping to canada? its been brought up a few times but i dont think there has been a firm answer

Thanks for the update.

While I really appreciate Dave topping up hashrates due to out of low spec boards ... it's too bad that the full kit orders end up paying more $ per GH than the starter kits ($48/GH vs $32/GH). It would be nice if Dave would consider giving the full kit orders a few extra boards beyond what's needed to hit 400 GH/s.
Sounds a bit entitled. hes giving what people ordered and people will still find a way to be unhappy and ask for more. starter kits cant get anymore hcards for august so you have an advantage over them by having more hash power on hand

Not unhappy or whining. Just stating the facts. Starter kits are getting more bang for the buck. That's all.

he said that the 400GH kit would be split as 2 8-board kits (each probably coming with 2 extra boards for hashrate correction), so you are actually getting an m-board and RPi for free if im not mistaken. that sounds better then the lonely extra 15Gh the starters get

Getting slightly concerned, hasn't it been about 48hrs since update, and no pictures yet?

Obviously i prefer he be assembling and testing, rather then busy on the forums, but I think that if things are where they are implied to be (m-board and h-boards in hand, in assembly, and with at least 6 orders marked 'shipped'), it would be comforting to see it confirmed, along with a picture of at least a few units running simultaneously.

I consider the August delivery met if there are tracking numbers provided on Tuesday, but missing a pre-order estimate by a less than a week would be very acceptable considering the examples of other companies. I am just a bit worried about how much potential 'testing to the 100TH mine pool' there would be facing Dave over a long weekend like this

Update soon i hope! (no BFL 'tm' intended)
3709  Bitcoin / Mining speculation / Re: Did someone just put 100TH on the network??? on: September 01, 2013, 05:14:28 AM
7 blocks in 12 minutes. something's not right. maybe bitfury should wait a while before being the elephant on the network

i have an order with them, so i dont want them to wait :p

bitfury europe units are arriving, the 200TH mine is quickly ramping up to spec, and the north american bitfury is in assembly/testing phase (another pile of TH)

It's always been a hobby for me, so I still want my ASICs, even if I won't make a net profit.
Though I can understand that for some of you it is pure business.
Anyway, I'd like my chips sooner rather than later.  Roll Eyes


there is other equipment available now that has a better ability to make a profit, as well as the fact that the produced K16s will be marked waay down in the near future (think asicminer)

Im in a similar boat as you, but a refund would be faster and better to re-invest in a gen2 product
3711  Bitcoin / Group buys / Re: [Closed]Avalon Chips - 0.081 BTC (Global+Escrow)-BATCH2 SECURED on: August 31, 2013, 07:39:54 PM
If there is a chance for this GB to refund, count me in Otherwise, I just hope to have my K16 (i only got one) ASAP so i can mine at least 50% back
3712  Bitcoin / Hardware / Re: Just purchased a ModMiner QUAD... on: August 31, 2013, 05:43:32 PM
I have seen reports that certain FPGA bitstreams (TML and/or bitfury) allow higher clock speeds and/or higher hashrates coming out, in the range of a 20% increase.

can anyone point me in the right direction or confirm this? For whatever reason my FPGA cards report:

44.6 C   212MHz   211.6Mh/s
31.4 C   216MHz   214.9Mh/s
43.0 C   208MHz   206.5Mh/s

the middle card's heatsink feels the warmest, so im not sure if the temperature reading is a bit low, or if the heatsink is seated really well. In either case, why is cgminer not setting a higher clock on this card? The total hashrate is 630 average over 24hrs, so perhaps that is a limit set in the bitsteam?

about time for an update from Dave, isn't it? Ideally, he should have all the boards in assembly and testing phase at this point
3714  Bitcoin / Hardware / Re: Which USB hub to use with Block Erupters or K1? A List. on: August 31, 2013, 12:39:48 AM
The 10 Port USB 3.0 Hub with a 12V 3A power adapter from Gearmo has been working exceptionally well for me using all 10 ports, especially @ $49.99 on Amazon.

http://www.amazon.com/gp/product/B00BZABGWK/ref=as_li_tf_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B00BZABGWK&linkCode=as2&tag=pin-im-suns-20

I bought 4 of these and they have been stable for well over a week now.  Not a single issue.   The only drawback is they are USB 3.0 which probably won't work with a raspberry pi.

https://i.imgur.com/1yrP4jn.jpg


My 4 original hubs are still running stable for almost 1 month now and I just added 4 more last week.  I really love these hubs.

 Huh you're running 10 in them? 3 amps should only support 6. is the power brick hot?

USB 3.0 is 12V 3A = 36W is more than enough
3715  Bitcoin / Hardware / Re: Just purchased a ModMiner QUAD... on: August 30, 2013, 10:43:36 PM
what if 3 cards work, and the 4th card lights up (the card's led, not the fan obviously) but is not recognised? All resistors look good, is the chip just bad/burnt maybe?

There are a few possibilities, all easily testable.

1)The LED on the back of the blade card should go off after configuration.  If it's not, that's the dead card if you only see three.
2) Swap the cards around - does the bad card follow the baseboard position, or the card?
3) Second, try with just two cards (one bad card, one good card).  If there is not sufficient supply voltage/amperage, you can end up with unreliable card detection.

I have good cards for the MMQs if you need any.  I also buy dead MMQs or swap for known good hardware.

1) LED on the card (in slot 2) stays on after programming
2) issue is with the card and not the position (i moved to slot 4)
3) power is not the issue - i removed 2 other cards

CGminer reports only 3/4 cards or 1/2 cards, and the led stays on, so the issue is definitely the card. As mentioned, it visually looks fine, fan spins up alright and no resistors are chipped or missing.

If you have any other suggestions id love to hear them! Could i perhaps use the reset button on the baseboard or reprogram the firmware to get a result, or is this just an issue that is likely the FPGA chip itself?

additionally, the unit will run if only slotspositions 1,3,and 4 are filled correct? (it runs the 3 working cards fine when the bad card is in slot 2, but its only in at the moment because of the cool leds) UPDATE: looks like slot 1&2 are a bank, and 3&4 are a bank, because putting the bum card in slot 3 causes slot 4 to not be seen by cgminer
3716  Bitcoin / Hardware / Re: Just purchased a ModMiner QUAD... on: August 30, 2013, 04:25:39 PM
also had a successful swap with bitweasil for my non-working MMQ.  Stand up guy as far as I'm concerned, Thanks!

Glad it worked. Smiley

For anyone troubleshooting MMQs, the DC-DC converter in the center seems to go bad far more often than one would expect, and the symptom is that everything works in terms of identifying the board, but the board cannot see any FPGAs.  It will look like everything is working but not find any chips.  You can also verify this with a voltmeter, though I don't recall offhand the pins to test.

If anyone else has dead MMQs exhibiting the "cannot find FPGAs" symptoms, let me know and I'll swap them out as well.  I'm not in any way affiliated with cablepair/btcfgpa/etc, but I have my reasons. Smiley

I have FPGA cards to fit these.

how much are the cards? (not for myself, but just a general valuation). I would consider letting this 3-card unit (plus 4th non-functional card) go for 1.75BTC or a good offer.
3718  Bitcoin / Hardware / Re: [ANN] US/North American Bitfury sales now open ***full prototype pics*** on: August 29, 2013, 02:55:56 PM

I seem to have missed all the shipping info in this thread as well.
I don't see it listed in the OP or on the webstore.

Has there been much info released on the free flat rate shipping?
Will flat-rate be processed at the same time as expedited?
Will there be tracking info for flat-rate?
Is it insured?


all the above questions, but for shipping to Canada (Toronto, ON). It makes no real sense for me to pay $199 for a starter to arrive a few days earlier when (for example) 3 days of mining sooner will earn less than $100

however, i am really interested to know how it will ship to canada using the default 'flat fee', my dream is to have it by next weekend to add to my modminer quad Smiley

whats the lowest order number? I am #13X for a starter kit and an october board

I am itching to have this in my hands ASAP, while profit still exists! Grin
3720  Bitcoin / Hardware / Re: [ANN] Bitfury is looking for alpha-testers of first chips! FREE MONEY HERE! on: August 29, 2013, 04:10:50 AM
So I got three more chips placed on my board... all seven are recognized, but it runs SLOWER than it did with four! Sad

Tweaking clock and voltage trying to find a happy medium.  Anyone have any suggestions?

same task being given to multiple chips and/or waiting for repeats of the result? sounds like the isue relates to how the chips are being sent commands
