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

Having gone through this whole BFL and Avalon (and partially BitFury) mess I takes nothing as granted

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

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.

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.

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

Well if you sit in a room with noise over 70dB it will eventually damage your hearing so beware!

Expect law suits in the future for Bitcoin manufacturers if they don't make the buyer aware and sell it under some kind of disclaimer.

don't forget that it's not USA everywhere..... damage your earing for few buck is not worth it... in add of the compagny is in Israël, so I believe that if you want to sue them, their answer will be GTFO NOOB.

Code:

System Uptime
41 day 22 hr 34 min 31 sec
CGMiner Uptime
37 day 22 hr 29 min 11 sec

This is really the most stable mining system I've used. Wish the BitFurys or GPU rigs were that stable

Mine never reaches that high because I'm a good boy and update the firmware

[ShadesOfMarble]

Well, once I had days of downtime because I thought it was a good idea to upate the AMD driver on Linux.

Now I know what "Never touch a running system" means

[ShadesOfMarble]

Just a small update. The unit is still running great, only once I received an idle notification from BTCGuild. Somehow cgminer crashed, but I could just click on "Start" again, didn't even need to reboot the unit.

As of now:

System Uptime
74 day 23 hr 3 min 58 sec
CGMiner Uptime
21 day 1 hr 24 min 20 sec

hi, sorry for bringing this up... i could find somewhere to ask.. did anyone delivered it to europe? how was the custom fees??

Custom fees are 0%
Tax may and will apply and the % depends on your country.

[ShadesOfMarble]

In Germany you have to pay 19% VAT.

BTW: Anybody interested in my SP10s? Need to get some space....

Initial post:

The SP10 offers the following modes of operation (first three columns taken from the webinterface, last column added by me):

Code:

1.00Th / ~720W  / ~quiet	/ 1,39 GH/s/W
1.35Th / ~1100W / ~quiet	/ 1,23 GH/s/W
1.43Th / ~1350W / normal	/ 1,06 GH/s/W
1.47Th / ~1370W / turbo fans	/ 1,07 GH/s/W

As you can see, the slowest (or "underclocked") mode is most efficient, whereas the two fastest modes offer about 20% less performance per Watt.

Update 24.04.14:

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.

Update 26.04.14:

what is the correct settings to get 720-900 watts at wall?

fan speed 50
start volts top 0.635
start volts bottom 0.635
max voltage 0.642
max power 800

dc2dc current limit 50

please tell me the correct settings on each one of them so i can get 1ths at 720-900 watts at wall this 1250 watts at wall is killing my power bill with 6 of them running.
 i am still pulling 1150 at the wall and it will never change i have the max watts at 800 and it still pulls 1150 at my wall.

how did you do this? i keep on getting 1150 at the wall.
1.00Th / ~720W  / ~quiet  is not possable.

720-900 watts is not possable. this 1150 watts makes my power bill $1,200 a month. i need to lower it to 720 - 900 watts. how do i lower it?  what is the correct settings to lower the power.  nothing is working.

i got 745 - 800 watts at wall  with the following settings

i have 800 watts at wall with the following settings hash is 1051 ghs.

fan speed  60
