ANTMINER S3+ Discussion and Support Thread

[Atomar]

For the PCI-e cables; What's the MINIMUM AWG cable I have to use for the S3 using only 1 PCI-e connector per blade ?
I know Sidehack uses AWG16 for his cables. Would a AWG18 also work ?

On the other hand, Gigampz sells 24" PCI-e cables with AWG18 ....

The SP31 does 5.5TH/s at 3000W = 0.545454 W/GH.

If you look at the other thread the definitive hashrate may be lower. We have to wait and see...

Just searched for "SP31" but could not find any other thread mentioning anything about the SP31 possibly getting rated lower than 5.5 TH/s. So which thread/posting do you mean?

EDIT: @RoadStress already answered that one, there is no thread about the SP31 possibly getting rated lower, all previous info was about the SP30 only.

Cablez sells custom length and will use 18 or 16 AWG you choose I believe.

[Atomar]

I try to make the cable by my self. That's why I ask about minimum AWG ;-)

Here it is, below, and there are more... Anyway we have not reason to  have doubts...

... There is also a chance that the SP31 performs like SP30 should have at ~6.6TH but I'd guess it's more likely it ends up closer to 4.5TH ...

Our commitment and guarantee is for 5.5 TH/s +- 5% with 3KW at the wall. It will probably preform better with the production tweaking we're doing.
By guarantee I mean that we'll compensate for missing hash-rate by the $/GHs ratio of the deal.

Isn't that what you guys said for the slow corner batch as well, what was that compensation offer I forgot, oh wait no one knows yet. Talk is cheap, actions speak louder than words. This commitment should be stated upfront with the details of what the compensation would be. Your track record hasn't been great taking into consideration the SP10 slow corners and now the SP30 slow corners.

With the current price of 0.58 BTC for Batch 8 Delivery on 9/20/14, and given their minimum quantity of 2 Units, recouping your money = Impossible. (Almost)

Factor:

(2) S3+ Units at .58 BTC          1.16 BTC = $585.00 USD
(1) Corsair 850w PSU                                $140.00 USD

TOTAL HARDWARE:   $725

Now, IF you are lucky enough to have power at a rate of 0.08 kW/hr (unlikely); and

IF Bitcoin difficulty only rose 11% per increase for the next 3 years, never more, (highly unlikely), and

IF you are lucky enough to get units that hash at the full OverClocked speed of 500 GHash; and

IF you are lucky enough, to within that 3 years, not have 1 single technical issue, pool outage, internet issue, power failure, hardware failure, and so on; it can be assumed

You will have made back your initial investment, and broke EVEN, on April 18, 2017.

Strato

Two flaws:
1. Equipment salvage value. Try the calculations selling the equipment at different time periods. You assume equipment worth $0 at end of time period, and that is not true.
2. No account for increase in BTC value. An increase in BTC value will probably increase the value of equipment.

2. You say accounting for bitcoin value increase?  Possible, could go 1000,2000,10000.  Problem with that is the nethash would keep up and surpass any gain as we saw. we already saw this in the honeymoon period of the last dramatic bitcoin increase.  

That is if we see spectacular jumps.  IMO more likely to go sideways until electric is just slightly less then profit made from mining and difficulty starts going up only a couple percent per adjustment.

Crypto world moves too fast and the guys example was being very very very very generous in the input values.

Bottom line is hw prices still have a long ways to catch up and make the distribution of wealth between miner and equipment manufacturer/cloud service more equitable.

use the cables that comes with Corsair if you have it (I believe that they are 18AWG), they get a little worm when OC to 237.5 (42C).
If you need splitters to split a single to two, I used Startech (they are also 18AWG).

are you kidding about 3 years? these are not Martian rovers that supposed to function 3 mo, but lasted 10 years already. If all S3 work after 6 mo, I would consider myself lucky.

How long have the Ant S1's been out? They are still going all day long for $125 on eBay, not worthless.
An S3 might not have value 3 years from now, but do your calculations for 1-2 years out when they still have value.

You can't ignore the increase in BTC value. Say I buy an S3 today for 0.7 BTC (about $350US) and with it mine 0.5 BTC over a couple of months (at current BTC valuation) at which point Bitcoin shoots back up to $1000. I now have $500 worth of BTC in my account, an S3 with a projected estimated value of $150-250, and I am only out $350 and the electric cost.

There is ROI there, it is not as bleak as you want all to believe.

BTC rise in value is irrelevant when considering profit. If you purchase the unit WITH BTC, had you simply just saved the BTC, at the end of 3 years you would still have the same amount of BTC.

So if .58 BTC cost will return .58 BTC return over a term of 3 years, had you simply held and not purchased, you would still have .58 BTC.

And in 3 years, the Miner, and PSU, will be worth nothing.

Purchasing a S3+ at .58 BTC is 100% - Hands Down - Burning your Money. You are essentially buying a device that costs .58 BTC that will, factoring all the near impossibilities I listed, return .58 back.

It's a lose lose.

Also keep in mind I was extremely conservative with difficulty increases. I used 11%. If it ends up being 13% on average... My rough numbers/estimate = ROI = 7 Years.

If you rely on the increase in BTC value for ROI you're better off just buying BTC. This has been discussed to death in various contexts and I've yet to see a compelling argument as to why it would be smart to make and indirect investment in BTC via mining hardware and take on multiple risks (exchange rate, hardware failure, bad luck/variance, difficulty increase etc) as opposed to just buying BTC and having only one risk (exchange rate).

In other words, if I pay BTC for the hardware my full ROI goal is the same amount of BTC. Not USD.

If you still think BTC value will help with S3 ROI look at the exchange rate for the last six months.

[Stratobitz]

An attractive price point for the S3+ in my view would be 0.35 BTC = ROI in roughly 90-100 Days if lucky.

And I honestly would not be surprised if we see a major price drop on the S3+, or BMT pulls the line to scrap the ASICs for future products.

Word has it, and I have solid info on this... they still have 1000s in stock unreserved for B8.

They are going to have to do something with those once they stop using them for mining.

BMT offering a "trade in" old equipment for coupons or something without expiration to be used on future equipment. I'm sure there's thing from the S1 to the S2, even the S3 that can be re-purposed for later equipment.

I think return shipping the unit to China would make that profit prohibitive.

I'm only guessing here, but my view would be after R&D costs, initial production setup costs, etc... The actual cost to Stamp an ASIC chip would be a few dollars at most.

Worth mentioning. I lost the ability to edit my S3+ order today. As some of you know, this has been a past indicator of BMT preparing to ship.
