[ANN] US/North American Bitfury sales NEW STOCK ***NOW SHIPPING***

[af_newbie]

A cost analysis shows that we would lose over 20TH if we ship out of the mine - taking over 800 cards out of the picture, which does not work well from a financial perspective.

This could be considered a grave financial impropriety.

Please enlighten me as to how that is adventurous to us, seems like we are funding the operation of your mine with our equipment and getting paid way less than our own individual strategies. What advantage is that to us, are you sending extra h boards to compensate? Because the BTC payment based on your decisions seems way unfair and you are profiting way more by holding our equipment while the production errors are catching up. Even now, we will not be able to achieve any ROI http://mining.thegenesisblock.com/a/9373700baf

which does not work well from a financial perspective

You apparently have the equipment as per your analysis. I know I paid the full overnight shipping fee for an August starter kit. If your taking 800 cards out of the picture by shipping out our paid for equipment, we are getting Avaloned and your decision to do this without asking those of us waiting for orders is a poor choice.

You were doing so good, what happened to you.

I asked them to send my order 149 without M-card.  I had order 89 that I placed few hours before 149.  I asked them to combine them, but they said they cannot do that so they sent out 89, but now they are holding 149.  I just need a working H-card from the 149 order.  They can send me M-card with my other October h-cards.  We'll see what they say.

Woohoo - got my starter kit out of billing-address limbo!

Aaand...

Hashrate 1hr   34665 Mh/s

At the pool!!


38W at the wall on 120V, which seems pretty good given how lightly I'm loading the PS (Corsair TX750).

I have some tips to improve performance on the software side that I'm collecting as I roll them out here;
I've got my pi's load average down to 0.10 and total CPU utilization at ~5% with only two shares rejected in the last hour.

  How did you get get up so high for 25Gh/s starter kit?

That's probably a fluctuation on the high side. The nature of Poisson processes means there's uncertainty equal to 2x the square root of the number of shares returned (at the 95% confidence level). That was 24480 diff1 shares at difficulty 32, so 765 diff32 shares; 2*sqrt(765) = 55, so I should report the rate as 34500 +/- 2500.

But, more to your point, pencil mod to achieve 0.74Vdd at the lowest voltage chip plus heatsink on back of board under regulator thermal vias. Stratum proxies running on external (fast) host; chainminer recompiled with

Code:

-Ofast -march=armv6zk -mfloat-abi=hard -mfpu=vfp -fno-strict-aliasing

instead of the default optimization flags. No manual chip tuning at this point. Estimate ~80% of the increase is due to the Vdd change, but I'm not going to slow things down to take better measurements I will note that if this were achievable on all 16 cards the full kit would be >550GH/s!

If you were using the latest cgminer you'd look at WU over a period of time to be certain of your real hash rate ... oh wait you can't.
Pool hash rates and short term hash rates can fluctuate dramatically.
Using a known accurate method will be way more useful that whatever you are using.
Oh well.

One of the selling points was a "fork" of cgminer (I am a mod on IRC #cgminer and do testing of cgminer). Well established and always forked.

The software chainminer using "getwork" REALLY,  it seems even a year after it's release, you have a patch work solution for stratum, the major protocol of mining pools.

chainminer has no relation to cgminer. Putin's comments on he'll work on it when he can, shows his priorities.

I asked specifically if Dave was sending a board to Con and Kano and he said he would, he didn't, guess it's another fail or bad decision.

+1 That is a mistake.  Con/Kano and don't forget Luke, could make cgminer/bfgminer work with these devices in no time.
It could help sales of HW.  (Although, I don't think they need help).

Is he going to support it going forward?

I suppose he will. He actually managed to get it hashing, but have other priorities right now.

No, I said that he has to deliever products to his customers first, and then provide support.

You said "suppose", the fact is you do not actually know. He has delivered all the product to his customer, He has his mine running, that might be his "other priorities right now".

[BenTuras]

wow, you're right. The pool is PPS with 7.5% fees, which is absolutely insane.

He is on PPLNS(3% fee), since he is also getting NMC. Only PPLNS gives merged mining NMC.

yes I did say that, because I am not punin. I saw the hashes he was getting with cgminer and I cant find a reason why he wouldnt continue to work on it, and provide support.

And no, he didnt deliver to all his customers, he only did august shipment. much more work ahead.

try harder.

And how is that a justification for using paid for and non-delivered hardware for his own purposes instead of walking his talk.

We managed to put up 10TH in un-optimized rigs today.  We fought networking gremlins early in the day, but still put together almost 50 rigs.  Tomorrow we'll swap out bad cards and should see another 5TH (reaching 35TH total for the mine).  More team members arrive tomorrow, so I hope to hit that 60TH mark.

Cheers,
Dave

Yes - 50 Rigs - how many outstanding orders - 53

August deliveries is what we are talking about! Your right, you are not punin, so stop talking for him.

[tarmi]

August deliveries is what we are talking about! Your right. You are not punin, so stop talking for him.

no, we are talking about you trying to get some sample hardware before all customers are served with existing/working software solution.

I paid for my August order! Which currently sits in Dave's Datacenter hashing away.

It wasn't a justification, it was just to ease the pain a little bit (7,5% versus 3%).

The real "pain" is that he is using hardware that was paid for and not shipped to customers at a greater than 16 to 1 ratio from what he is compensating people who are waiting.
