Anyone here achieved better results on a 270X card in power efficiency to KH then what I got below?
over me? Just curious what was the lowest voltage you got stable at the most efficient clocks?

Here is what I got below with tweaks and a watt reader.

Below is for N-Factor coins.


545->348->318 Watts=227 Saved watts.
197/3=(76 Watts/Card)

270X Card, Other cards coming later to be added.

545 Watts at Core 1030 Memory 1500 Yeilds 220 KH *Voltage 1.206
348 Watts at Core 929  Memory 1400 Yeilds 198 KH *Voltage 0.925
318 Watts at Core 929  Memory 900  Yeilds 192 KH *Voltage 0.925
2.47 Watt per KH -> 1.758 Watt per KH -> 1.656 Watt per KH
1.656/2.47=0.67, 1-0.67=0.33
33% more efficient Ratio.
41.6% Less power.


Due to the lowering of profits, it seems a sweet spot is what matters now, its amazing if tweaked right
can get you much more efficient watt to KH ratio.
