Just tweaked mine in a little more but still messing around actually.  I got a EVGA 1060 6GB SC edition card. Im mining Zcash.
Originally was +230 Core (1850-1900Mhz) and +400 Mem (4200Mhz) = 323 Sols/S average with 80% TDP (96W) ~3.35 Sols/W
New Adjustment +325 Core (1797-1809Mhz) and +400 Mem (4200Mhz) = 316 Sol/S average with 72% TDP (86.4W) ~3.68 Sols/W
