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

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.

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

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
start voltage top 0.59
start volts bottom 0.59
max voltage 0.61
max power 800
dc2dc current limit 62
ghs is at 1051 avg and 933 5sec after 19 min uptime. done on a 110v wall outlet.
