my laptop (SVF15N17CXB) got a nvidia 735m on it

while gaming like dota 2 fps drops to about 20

when i checked GPU-Z i saw that the GPU clock and the Memory clock drop to 400 and 405 Mhz, i tried Nvidia inspector to set a fix clock on all states, i set it about 940 and 780 Mhz for GPU and memory in every state but still clocks drops to about 500 while throttling cause of down-voltage. voltage drops from 1.18 to 0.85 in throttling and setting it in inspector is not available (grayed out)

i tried EVGA Precision X to set a fix FPS (35) the load is low in game but throttling still occurs but clocks go high again in one minute

the throttling does relate to temperatures sometime it drops in 70 degrees sometimes in 62!!

 
How old is the laptop? if under waranty, just ask them to replace it (they will be able to put your old harddrive in the new computer

next step is to go install current drivers.

after that, go into power options and set everything to max performance (im sure you already did this but it's worth a mention)
