1050 in notebook overclocks nicely and for everyday use you can actually lower to voltage to significantly reduce heat (thus making it even safer, than stock). I dont know, if rising voltage is possible, but in regular scenario wouldn't advise (for testing purposes with cold air, why not).
I have 7700hq and 1050 4gb.
For overlocking (and lowering voltage) use afterburner.
Ctrl + F for voltage and core speed, memory speed is set through the slider.
Default: core: 1690mhz, ram 1750, volt 1.063 (firestrike 5500)
High (not tested to max): core: 1910mhz, ram 1866mhz (+220), volt 1.025 (firestrike 6040)
Optimal: core 1800mhz, ram 1850mhz (+200), volt 0.950
