Black Arrow R9-12 threads, DZ Miners Co-op. Plz move ?s and discussion here.

interesting I have seen this under reporting quirk quite I bit..  Lots of pools and lots of different gear and software.   I saw back in aug 2012  and in dec 2012 and more recently.  So we kind of have a fully custom setup…..  Should we pick up more pi's to switch in and out.

Like wtf? By the time I was up and got over to the warehouse, they fixed themselves. Our 24 hour earnings never changed tho...

yep  this is what I have seen on other pools such as bit minter  with the bit minter java client  and with the bfgminer client.     now a day or 2 ago bitminter had 8 or 9 stale mmc blocks in a row.  so these under hash/ vanished block bugs have occurred before.

Looks like they rebooted them earlier and they are climbing back up.  Not sure what you mean, they have bent over backwards to deliver the promised hash and have refunded us for lost hashing time.

He just means that the hashrate isn't really hitting the promised minimum most of the time, usually it's hanging out a little below what it should really be at, even when most of the stacks are supposedly working I've only seen it get up to about 3200Ghash.  Right now it looks like it's at 7Ghash per share on the site.  I think the bitfury boards have been a lot more problematic than expected, everyone was hoping that they'd be overclockable to 10Ghash a share but the boards are so unstable it's nearly impossible to get even 8.34 per share.  I haven't actually seen only bitfury boards hashing away at over 8.34ghash per share, the only time we ever hit that hashrate was with the KnC Jupiters thrown in to hit the goal rate.  Hopefully whatever software or hardware issues get worked out, but so far it seems like bitfury is really hard to keep running reliably vs the other hardware out there.

Has the payout happened yet? I haven't seen mine come in yet.

[Mapuo]

And we need compensations to 8.34 GH/s

Payouts happened and they are running the Jupiter to boost our hash rate.  What more are you expecting exactly?

8.34 GH/s per share minimum. Now speed is no more than 7 GH/s.

Worker 1 Hash Rate       2313.632 Gh/s
Worker 2 Hash Rate       0 Gh/s
Worker 3 Hash Rate       520.13 Gh/s

Now is 2833GH/s, promised is 3336 GH/s

P.S. OMG, not now, last two weeks speed is the same

You have a good point, no one is trying to dismiss you.
I have been working on these boards, and as you can see from "Worker1" they are way under, even with my personal Jupiter running.

We have several options here:

-I can continue to work at it, but the fact is these bitfury boards (and the chips in general) are not reliable hashers. We can do a small BTC refund for the less than promised hash rate (to be distributed in the next payout)

-I have received an offer to purchase all the boards I have in $, and I can sell them then divide up all the money evenly between 400 shares and refund everyone the appropriate BTC at the exchange rate.

Thoughts yall?

EDIT: I am trying to be as upfront and transparent as I can here, I have just been absolutely swamped the last few days (holidays + trip to china + see barntech's thread)

[madpoet]

I guess it depends on how good the offer is for the boards.

[nicksmith]

I vote to hang in there, yes its a lil less, yes ill ROI just fine at this rate.
but yes if offer good enough to cash out....

first off the buy has done roi in usd terms.  


 I am in a funny spot as I have an 11 spot of shares here R9-r12 and 19 shares in r5+r6.

  I just got 2.5btc on sunday between the arrows and the knc.  I am beyond roi in terms of usd.

  So In one way if DzCoop sold both knc's and all the  ARROWS  FOR A GOOD PRICE  I would see a lot of cash.  As always I am A half loaf guy… I don't want to hold all and just mine and I do not want to sell all.    I am like split the thing in two.    Sell some gear and keep some gear.   this way if btc goes to 10000 we do well and if btc drops to 100 we do well.  My 2 cents.

The offer per board was $900+ each.

[madpoet]

bob sorry I don't know the original price, number of boards, etc;   I just know what I paid you.  Given that price what would the USD per share be for us?

[philipma1957]

is it 80 boards for 900 = 72000K?

[bobsag3]

is it 80 boards for 900 = 72000K?

72k* And there abouts yes. I will have to get more information on the offer etc, but it should still be good.

[madpoet]

So about $180 USD a share?  Tempting.

[redphlegm]

I suppose we should leave this to DZ/bobsag3 but my vote is no. That's a terrible return on investment in BTC terms - and that's what these are: BTC generating machines. Do we basically have to deal with the flakiness or is there any potential for tweaking them to not be so flaky? Is the pi the issue? Would it be more reasonable to get a cheap netbook or something and throw ubuntu on it? I'd just like to understand the options as they currently are. Selling is one option and dealing with the flakiness is another option but what other options are there?

[Ridicuss]

I would like to chime in here and first say Thank you! to the GB operators and especially to Bobsag3 for having the job of keeping this beast running, and to Thomas for dealing with payouts on all the GBs.

This might not have been what we all thought it was going to pan out to be in the beginning as far as hashrate goes goes but we have much to be thankful for.

1.) We were promised shipping of the gear on or before Nov 1. There was no promise of the beast hashing on Nov 1, But low and behold, We had Hashing on Nov1. Realistically we could have lost days to setting the gear up but Bobsag3 cranked it.

2.) The hashrate did not hold and we were compensated with I think 7 BTC to the payout by the DZ guys themselves. I dont know of anyone else that would do that.  They did not have to give us that 7 BTC.

3.) The last part is because of the BTC explosion. Depending on when you cash out your BTC from this GB as far USD goes you should be money ahead now.  I know I am very pleased with the outcome of this GB and am glad I got in on it.

Was it optimal. No, but as far as I can tell every effort possible was made by the DZ Group to make this right in every way they can and that speaks volumes to me about how much they want all their GBs to succeed.

If some are not happy about the hashrate please dont think this long ass post is trying to discount your concern. Your concern is valid and your voice counts.  I only wanted to post what I call the positive parts of this group buy.

Think of where we would be on this group buy if Bobsag3 did not give us the use of his jupiter..  What if he did not have a Jupiter to loan. Now that would suck.

Thanks Bobsag3!

+1 on the Kudos to DZ/bobsag3

Theres plenty I can still do/try, its just time consuming and frustrating. That is my plan to go from now, unless we change or minds.
