Hi everyone, I am making this thread to share everybody's experience on overclocking the GTX 660m.
I have the G75VW-BBK5 (Best Buy version) and I am more than pleased to tell you that I have reached +135 on the core and +350 on the memory clocks. I did not push the memory any further since I did not wanted it to overheat. The clock is maxed out with +135, I can not push it further, EVGA Precision did not let me go beyond that point. So far it hit only 68 C which is by no mean a terrible temperature. I made the test and taking out the bottom cover so that air can flow directly into fans and GPU temps did not hit 65 C... IMAGINE WHAT YOU CAN DO WITH NO BOTTOM COVER AND A COOLING PAD !!
The moment of truth was 3DMark Vantage where I WAS ABLE TO MAKE 13900 !! This thing overclocks like a beast.
Just thnx for your time in reading this, and leave your experience too !
