GT 650m Throttles at low temperatures, any ideas?

post #1 of 4
Thread Starter 
I have a Lenovo y400, and I finally learned to overclock.
So I overclocked my gt 650m from the default 790mhz from the core clock and 2000 from the memory clock to 1000 mhz core clock and 2250 for memory clock.

It's all excellent, the boost in my fps is really incredible in some games like the Witcher 2 or Metro last light.
Until the other day that I was playing L,A Noire and after a few hours of gaming the laptop started to throttle and I get a message from nvidia that the video card stopped from working but then recovered succesfully and I think that is throttling but my temperature was only 72-73C and from what i've been reading that is a fine temperature from playing games with good graphics.

So any ideas? maybe a fan pad or something? or what Im doing wrong? Im new in this thing called overclocking so any help would be amazing.
Sorry for my bad english, Im trying to do my best here. smile.gif

Sounds like it needs extra voltage to maintain that overclock.

So, how can I do? or is it bad or what do you suggest in this case?

Let's put it this way, it won't hurt it to run like this, but it will keep crashing. I have a Lenovo Y410P and can tell you that the voltage is locked on it, meaning you cannot make that overclock stable, you will have to lower it to return stability.
