Review of the Spondoolies-Tech SP10 „Dawson“ Bitcoin miner (1.4 TH/s)

Could we get a video of the fan noise.  Start video, turn unit own, struggle to hear you talk over noise 

That should be possible

I now have some more numbers to present:

Code:

 Mode (Web UI)                                   | Performance | In/Out Temp   | Power (Wall)
------------------------------------------------+-------------+---------------+---------------
Idle                                            |    0 Gh/s   | N/A           |        35 W
1.00Th / ~720W  / ~quiet     / 1,39 GH/s/W      |  1139 Gh/s  | 29 °C / 67 °C |  780- 820 W
1.35Th / ~1100W / ~quiet     / 1,23 GH/s/W      |  1341 Gh/s  | 29 °C / 82 °C |	1150-1200 W
1.43Th / ~1350W / normal     / 1,06 GH/s/W      |  1412 Gh/s  | 29 °C / 79 °C | 1340-1380 W
1.47Th / ~1370W / turbo fans / 1,07 GH/s/W      |  1456 Gh/s  | 29 °C / 76 °C |	1380 W
------------------------------------------------+-------------+---------------+---------------

The power measurements were done on a 230 V circuit. The numbers for every mode except "turbo" and "idle" fluctuated, so I included the lowest and highest reading. The "average" power draw is somewhere in between. In normal mode, the unit hits the advertised 1.4 TH/s exactly. "Turbo" mode does not give much more performance (about 3,1%), but decreases the temperature by 3°C. The lowest performance mode also gives the lowest temperature, whereas the other quiet mode gives the highest temperature  (3°C more than "normal") and a 5% reduction in performance compared to the standard mode.

So, as the "quiet" mode does not deserve its name (I would rather call the mode "efficient", as that is what is is - more energy-efficient than standard/turbo) - my recommendation is to either run this unit using the (slowest) 1Th-setting, which will give the best performance per Watt and also a low temperature. Otherwise, one should choose "turbo" mode over "normal" mode because you get both a lower temperature and a bit better performance at only marginal increased power consumption.

Thank you for the review too. I was using the Normal mode until now. Will give the Turbo mode a chance too.

I STILL HAVE A UNIT IN MY LIVING ROOM, YOU GET USED TO THE NOISE LEVELS AFTER A WHILE.

send it to me I have a  place for it.


seriously I am in Howell NJ 07731.

pm me with a price and I will take it off your hands.

I don't understand how people can sleep in the same room with their rigs??? I go sleep to other room or otherwise i couldn't sleep when hearing the noise.. That just doesn't sound a smart thing to do.

He mentioned living room, not Bedroom

I often sleep in the same room if I'm too lazy to move, you get used to the noise pretty quick. It's also a constant noise so it's less disruptive than traffic for example.

Liquid submersion cooling is the next step:

This is the future but I am not sure if mineral oil will be the mass deployment coolant.  It is still pretty messy to service.   I am working on a project with another coolant that is a little less messy.   Regardless this is cool and green tech.  I love it.

It should be possible to deploy immersion cooling at large scale, as shown here: https://bitcointalk.org/index.php?topic=346134.0

Looking good!

2$/G Is a little for me, i think 1.2-1.3$/G is a reasonable price for everyone

You can get under 1$/GH in my group buy, but for pre-ordering. Nobody has 1.2-1.3$/GH for in stock items.

Agree. And the noise can't be worse than my tinnitus.

seems like a high end high quality server product. bottom line.1u and a high noise level are just part of this. hosted mining is the way of the future. power also is a issue not sustainable by hobby miners homes generally speaking. spondoolies is just building the next logical step and moving the mining industry forward. away.from the hobbylike setups.

Very nice!

Web UI screenshots can be found here: http://imgur.com/a/H3dee - Nice, clean and functional.

The SP10 is now running for over two weeks without the slightest problem. It's just delivering rockstable 1,4 TH/s.

If I compare that to my BitFury units, which cry for attention all the time....

I think thats getting pretty much the norm now. My 1T Dragon miner has been up for just about 6 weeks (5w29d) without a problem at a stead 1020Gh/s Avg.
