I just bought one of these used because it was a decent price and wanted to share some of my findings. The gt650m uses nvidia boost, however there seems to be a flaw with the software controlling it, at 67c the gt650m (rated much higher) throttles down from it's boost speed of 835mhz, that's not the problem the problem is what it throttles down too. Instead of going to it's stock clock, it goes all the way down to 535mhz. Like clockwork at 67c this occurs, confirmed on a10 and a13 bios (the ones i've used) i suspect more likely that it is a function of the cards bios. It seems to be a common problem with this model so after a little research on overclocking it, and making sure that the shared cooler doesn't have issues keeping the card at higher frequencies, usually my i7 is at 85c, and the gt650m is at 71c with my current clocks.


-Here is what you must do, first download Nvidiainspector. Download
-Open it and click show overclocking read the disclaimer and click yes if you'd like to continue.
-set the performance level to p5, unlock max clocks and set the desired clocks, i recommend the boost clock to start off, so 835mhz, set the memory to 2000mhz.
-Click create clocks shortcut which will create a shortcut on your desktop to set those clocks
-in the nvidia inspector folder create a .bat file that has a line "nvidiaInspector.exe -forcepstate:0,5" without the quotes
-create a shortcut for convenience, i named mine no throttling.
-before you play a game run the .bat then the clock files, this will lock the card into a p2 power state allowing no fluctuation of the clockspeed.
-create another .bat file in the nvidia inspector folder on this one you want have a line "nvidiaInspector.exe -forcepstate:0,16" without quotes of course, this will return the card to it's original power state. run this one when you are finished with your games.


Make sure to monitor your temps at first, as far as i can tell they set the barrier far too low, but as the gpu and cpu share a heatsink it would be wise to do so. If your temps allow it feel free to bump up the gpu clocks higher if you feel comfortable doing so, and enjoy your m14 the way it's suppose to perform!
