[ANN] Spondoolies-Tech - carrier grade, data center ready mining rigs

[BitCoin Operated Boy]

So far I have not noticed anyone on any bitcoin thread pointing out the importance of this mining factor.


Toomim brothers are loud-n-proud about their eco-friendly hydro power (as they should be).

neX:)

Their hydroelectric power is ecocidal as f*ck. It comes from the hydroelectric dam which was built upon decimation of the environment's flaura and fauna as the basis of the design.
And also it's terribly ecocidal for the existent ecosystems, up and down the river.

When will you state your AM affiliation in your signature? It is fair for everyone to know, just like they see in my signature my affiliation to SP-Tech.

When I participate in the signature campaign and get paid to do so. Will that change the maths though?

SP20: $1,190.00  + $300 PSU for 1.7 Th/s = 0.88 USD per Gh/s
SP35: $3,920.00 for 6Th/s = 0.65 USD per Gh/s
S3+ B9: 0.58 BTC @ 453 USD/BTC + $50 PSU for 453 Gh/s = 0.69 USD per Gh/s
Tube: 0.889 BTC @ 453 USD/BTC + $100 PSU for 800 Gh/s = 0.63 USD per Gh/s
10 x Tube: 7.9 BTC @ 453 USD/BTC + 10 x $100 PSU for 8 Th/s = 0.57 USD per Gh/s

Given that you don't try to refute my argument that the SP20 provides terrible value, do you agree with that statement?

[dalekay]

if noise is a problem, why not just change out the fans ....
example http://www.coolerguys.com/840556082507.html
there are many fans made out there with specs if you are that detailed ... that are far less noise than what might be in these cases ....

I am looking at the SP 35 myself. They would be placed in a studio that is also used for filming and such. I expect to shut them down when noise is a problem but I can also alter the fans too if need be and perhaps not have too.

Looking at the AM Tube too in the same way ...

It does not matter. There's no global warming by far, the cheapest reliable source of electricity is nuclear .. until someone invents something to collect it from thin air ..

Honestly if you are worried about noise, then don't by a SP3x

If you are going to mine throughout part of the day because of the noise then just don't bother, you'll have a hard enough time mining your money back if you run 24/7/365 let alone missing out chunks of the day.

These rigs are designed to live in a rack, in a climate controlled datacenter, their form factor, power usage and their fan performance and therefore noise have been chosen with that very factor in mind.

There are lots of slower, bigger, cheaper, less dense, lower power (per unit) devices that are better suited to home mining out there.

Swapping the fans isn't an option on the SP range of miners, if it was they would have done it. If you swap the fans for slower quieter versions then the device will overheat and slow down.

[seriouscoin]

Looks like SP-T shoot themselves in the foot with SP20s....


Why oh why?

SP-T, please considering building modular system for future products. Mining hardware cost is so sensitive now that parts are not disposable anymore. ie Case, PSU, controllers.... all that goodies.

Please build a motherboard and daughter mining board platform.

Really you only need an EVGA 1300W PSU and they are around $180

And you need to add in the cost of shipping. The S3+ includes shipping. The SP20 doesn't.

Which would take it down to 0.81 USD per Gh/s and makes it:

24.62% more expensive per Gh/s than SP35,
17.39% more expensive per Gh/s than S3+ B9,
28.57% more expensive per Gh/s than a Tube, and
42.11% more expensive per Gh/s than a 10 Tube set.

In other words, it still provides crap value and that's without the shipping fee.

Pretty sure these fans would take care of it fine ... easy to change out a fan too ...
my plan for the SP 35 ... tubes the same way ... yep they will run 24/7/365 in a nice cool place till needed to quite.
I just don't think the noise is going to be an issue for me, others, do check out the other fans out there ... watch the air flow compare with what is already inside.

Happy mining ...

Good luck finding quiet 100 CFM 80mm fans.

It does not matter. There's no global warming by far, the cheapest reliable source of electricity is nuclear .. until someone invents something to collect it from thin air ..

Isnt hydro power heat neutral?  The potential energy has to go somewhere whether they open the bypass sluice gate full or feed to the turbines/generator full, and as we know the miners output is also all heat.

From initial testings with the slow ASICs we currently have, we see great over clocking potential in the SP20.
The limiting factor is cooling, and we're working to improve it. Experimenting with various enhancements to the heatsinks.

Umm no. Snuclear ain't all that.
Nor is hydroelectricity, nor coal or wind.

If it ain't personal it is going the wrong direction. Energy needs to be democratic.

Nice to see some twerking of the heatsink going on there SPTech loved to see the results of those tests.

Good hear this. Can you please comment on this:

Why is the SP20 less efficient than the SP35?

I thought they used the same ASICs?

SP20 1100W / 1700 GH/s = 0.65J/GH
SP35 3500W / 6000 GH/s = 0.58J/GH

I'd rather buy the SP20, mainly because I'm hoping it will be quiet enough to use as a heater at home, but it is hard to give up efficiency.

Indeed same ASICs.
The SP20 should give better results then what we published. We'll get the faster ASICs in 2 weeks and revise the spec.
Also, iit depends on the PSU efficiency.

Thanks! Keen to hear revised specs as soon as they are available. Sounds like SP20 efficiency is understated at the moment.

Thanks for the info on CFM.

What is the db of the existing?

here are some 80 mm at 100 CFM or higher ..

While poking around I noted some talked about just putting in more fans, with out knowing the layout of the inside, sounds possible ...

However mute it might be after this year on this unit anyway ...

[Master One]

Well, I have to admit that I'm currently waiting for the S4 specs and price be revealed. Although there is no valid point in investing in mining now with difficulty going through the roof (network hash rate has already spiked to above 260 PH/s, currently sitting at 250.5 PH/s) and BTC price in the cellar, I'm prepared to purchase my very first mining gear, because winter is coming and my plan is to let the miners assist in heating the house.

SP-T has really something going here, but unfortunately the long delivery times, high price and especially the high shipping costs speak against the purchase of a SP20 or SP35. Considering the total purchase price Bitmaintech offers a better $/GH rate, and although SP-T had a better W/GH rate so far, it may be beaten by a S4 with underclocked/undervolted ASICS.

$/GH and W/GH both have to be right, which is why those Tubes with W/GH way off can not even be considered.

I'm not giving up on SP-T, but something has to happen, because it's just not working that way. We need some innovation to bring W/GH below 0.5 and price + delivery times down, which may be impossible right now, but I have hopes for 2015.

Let's assume a static network hash rate of 300 Ph/s, power costs of 0.1 USD/kWh and an exchange price of 500 USD/BTC.

SP20 costs 2.64 USD/day,
SP35 costs 8.4 USD/day,
S3+ B9 costs 0.86 USD/day, and
AM Tube costs 2.16 USD/day.

SP20 at 1700 Gh/s would mine 0.0204 BTC/day or 10.2 USD/day,
SP35 at 6000 Gh/s would mine 0.072 BTC/day or 36 USD/day,
S3+ B9 at 453 Gh/s would mine 0.005436 BTC/day or 2.72 USD/day, and
AM Tube at 800 Gh/s would mine 0.0096 BTC/day or 4.8 USD/day.

SP20 would make 7.56 USD/day profit,
SP35 would make 27.6 USD/day profit,
S3+ B9 would make 1.858 USD/day profit, and
AM Tube would make 2.64 USD/day profit.

SP20 costs 1,500 USD inc. PSU + shipping, it would take 199 days to break even,
SP35 costs 4,035 USD inc. PSU + shipping, it would take 147 days to break even,
S3+ B9 costs 320 USD inc. PSU + shipping, it would take 173 days to break even, and
AM Tube costs 500 USD inc. PSU + shipping, it would take 190 days to break even.

The network isn't static though and AM Tubes are the only miners in stock. I'll leave you to draw your own conclusions.
