105 Gh/s ASIC miner: Redhash by TAV. (Limited availability on eBay).

[AdamKD]

Do you guarantee certain performance on a per hashboard basis or per backplane connection?

Error %?
Hashpower ?
Possibly at a default frequency? (It appears they are clocked at 328?)

That is, are all your machines clocked at 105 gh/sec or are there a number in the high 80's low 90's range?  Therefore, not all machines are running 105 gh/sec but that is clearly a peak.


On the server picture it appears you have 62 red cases.  Eligius indicates 31(+ partial unit{s}?) miners running.

31*8*4*10= about 10k chips.  Are 31 of the cases empty cases in that photo?  You've indicated an order of only 10,000 chips.  If so - why?  Was there a 10k chip order that was refunded and you have an interest in G2 Avalon chips?  If so, what information do you have!

Curious

Also, grats.

Same question was posed and answered just one post up. And judging by the answer,  I wouldnt be surprised if the empty cases will soon be filled with bitfury's.

It's a similar statement, but not the same - there's no question mark so it can't be a question.  Also, no questions posed by me ask about the future only the past and the present - though the last one might be classified as a fishing expedition  .

Actually this estimate is incorrect. If you look carefully, the first mining month is estimated as having a diff of 293 million(!) Our units will start shipping on October 2nd, when we will still obviously be at the current difficulty 149 million.

We'll be at (or about-to-be-at) 200 million when they arrive a couple of days later though, and you had to fiddle the electricty rate down to show it getting an ROI :p

This is a big flaw of the mining.thegenesisblock.com calculator...

It also incorrectly assumes the difficulty will remain constant for a whole month - which it never will - so (putting aside the %age growth will eventually slow down argument) generally it paints a far-too-optimistic picture !

Sadly though with the power consumption, even though it's a great design and engineering feat, and major kudos for actually having a product rather than pre-ordered vapourware, anything over 8BTC is unlikely to ever break even for the majority of potential clients.

[topminingcontracts]

Very nice job,

I am wrong or "in hand" is the most competitive price per GH and power consumption?

We can't compare this with other units that in fact don't exist.

Today in hand I see the ASICminer blades and this unit... and this one is by far a best investment.

good job guys....  quit hating on people that have something inhand to sell today....  105ghs this week is better than 1TH/s that hasnt been prototyped and is months away in a best case scenario....

I'd have to agree. At the next difficulty change 15 BTC will just be too high.

It's not hating, it's math. I don't think anyone has any hate for TAV (a miracle by itself).

The problem is that the difficulty is correcting at such a sharp rate over such a brief period of time that you have to buy it at a price that is worthwhile in a realistic sense.

The returns get squeezed faster than someone slamming on the brakes.

Update:

For international shipping, we highly recommend to ship the Redhash unit without the Power Supply Unit as its presence may cause issues at Customs during import. You should instead purchase a standard PSU on your local market (850 Watt minimum). Of course the decision is up to you, but if you choose to have the Redhash unit shipped without PSU, we will take 0.5 BTC off the price you bid.

[mrb]

AdamKD: we guarantee all redhash units achieve 105 Ghash/sec +/- 5%.

astutiumRob: diff will be 149M at least for domestic customers (which we expect to be the majority of our customer base.) Next diff is estimated to be only 180M per allchains.info, very far from the 298M people were quoting. Also the average worldwide electricity price is $0.10/kWh. It makes sense to pick this one as the default. And again we expect our auction to naturally attract those with lower than average rates.

Don't even try to defend the ROI. It's just not there. These will not break even at the current bid prices unless you have nearly free power.

Then don't bid.

There are problems with the genesisblock calculator in terms of granularity.  Either other people feel they're worth it, or they're paying more than they expect to get.  In any case, all mrb is doing is running the auction and providing information on the hardware.

No, he's also trying to justify the ROI on them. That's where he's going too far.

15 BTC with units shipping now is clearly profitable: http://mining.thegenesisblock.com/a/44fc645248 (55% month-over-month difficulty increase), and even a pessimistic 100% month-over-month increase is profitable. Also, 15 BTC for 105 Ghash/sec beats the price per Ghash/sec of any competitor shipping now or in October!

That's only true if you go back in time and start mining Sept. 1.  If you start on Oct. 1 they are only profitable by 0.05 BTC with 55% diff increase and 100% increase is just bad.

Edit:  I miscalculated the 55%, they are profitable if it is only 55%.  But I don't believe 55% will be what we see.

No he's not. His defense is valid. Maybe incorrect, but we don't know that.

He ain't holding a gun to any of the people bidding. They are or are not doing their own due diligence. Clearly, they believe it worth the price, or they wouldn't bid on it.

[wrenchmonkey]

great work guys, this is what the mining community needs.

Wow - even landed kudos from the man himself...

Why is this such a shocker, this what we wanted in the first place, and been our message since day one.
to be fair though, except reality of making few thousand units is a lot harder than making 30, I hope you guys can scale properly.

Holy shit. Fuck this loudmouth piece of shit, SOOOOO much.

Listen up, you feckless waste of oxygen, their problem is not scalability, their problem is vendors whose "no bullshit" contracts are all bullshit.

I hope Avalon goes bankrupt, and these guys find a reliable vendor that isn't run by a smug self-assuming asshole like yourself. Of all of the people who ought to shut the fuck up about best business practices, you're pretty much top of the list.

"Scale properly" indeed...

Please realize you make an incorrect statement out of literal rounding errors.

Demonstration: change your analysis' power cost to $0.085/kWh (still very close to the worldwide's average, 15% below it, hardly what I would call "nearly free power"), and change the monthly difficulty increase from 100% to 95% (just to demonstrate you are playing with rounding errors) and ROI is achieved in Jan 2014: http://mining.thegenesisblock.com/a/5ce6d144b8

Therefore you cannot claim "ROI is just not there", just as one cannot claim "insanely great profits are there" (with a 19 BTC price and ~100% monthly diff increases). Which is why I am taking the middle-ground position of "ROI will approximately be achieved (either slight losses or slight profits) in this hypothetical scenario".

Also, as others pointed out, I am not claiming a ROI in all scenarios. Fundamentally, neither I, nor you, know future monthly diff increases:
- They could be 50% in which case great profits will be made.
- They could be 100% in which case ROI will approximately be achieved.
- They could be 150% in which case losses will happen.

I'm on your side on this, but since you are correcting technical errors, I am too.

To put this in some perspective, the study of economics is my hobby. Particularly the Austrian school, but in this case we're talking general accounting. I've made this point several times, and been called a troll for it. I'm not trolling, I'm genuinely irritated by the misuse of a well understood accounting term.

There are three ways that a hypothetical buyer would not make ROI on this.

1. The unit is DOA (which you have contingencies in place for.)
2. The buyer puts it in their trophy collection and never mines with it.
3. The buyer doesn't use it, gets a refund, and goes on their merry way.

ROI stands for Return ON Investment. Not Return OF Investment. If it mines at all, you make a ROI. This is not an ambiguity or a hedge, this is what the term means. ROI is a moving target. Now if you, or the hypothetical buyer, says "it will not make ROI in X timeframe, they MIGHT have an argument, based solely on the above three conditions. What the majority of the people on this forum MEAN, seems to be breakeven, which is an entirely different subject. This isn't picking nits, this is what the term means.

ROI can be positive, negative, or breakeven, but if it makes you one satoshi, you have achieved ROI.

I find this misuse egregious for the same reason I find the religious argument "it's just a theory" to be egregious. At least in that case, there are two different meanings to the term. In the case of ROI, there is not.

"a return" in this context is synonymous to benefit and to me at least, without qualification implies a non negative, non zero value. The context makes it quite clear and Im perfectly fine if people leave out unneeded words.

Compare it to discount. In theory a discount can also be zero or even negative, but when someone says they get a discount, a positive number is assumed.
