MSI 1080Ti Sea Hawk EK cards.  The above figures were a surprising run with power level at 95% in Afterburner on all 4 cards.  It was a one time "hero run" I think as I was never able to replicate those number.  I've settled for running at 78% PL with core at +155 and memory at +600, which is giving me the following:



Which is more inline with what my air cooled 1080Ti rigs are giving me.  It just didn't make sense that, as I kept increasing power level, the efficiency remained at around 3.85 Sol/W.   I'm on 0.5.2 btw.
