Awesome.
Msi 660Ti PE OC are running at 1402MHz core in Kombuster on std cooler, 1500mhz should be easy on water now..
Measured voltage under load is 1,275 with multimeter, at +40 mV in afterburner, std volt shows 1,25volt on mm with 0% powerlimit.

+100mV (max) and 0% powerlimit gives 1,32 under load.
+100mV and 150% powerlimit gives 1,35v load.
