Title: Graphic card sweet spot, KH to Watt ratio. Post by: lightlord on April 02, 2014, 02:38:58 PM 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. |
