I started a few days a go overclocking my gtx660M in the G46 laptop. One thing I don't understand is this: my temp at core 1150(from 835) and 2700(from 2500) memory I get about 74 degrees. yet when I go to 1150or 1200 core the laptop shuts down before the game starts (any game: watch dogs, ryse, middle earth etc). i'm guessing it s the low voltage? there's no way that going from 1150 to 1200 rises the temp so much that the laptop has to shut down (aka BLUE SCREEN) :(

I can only hit 1100mhz core and 3000mhz mem stable on my G55 with GTX 660M. Try lowering your clock to 1100mhz and try increasing memory to 3000mhz? Probably a voltage limitation.
