Overclocking G75VW-BBK5 w/GTX 660m

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 !

Hey frizodanizzo, which drivers do you have?

I have a G75vw-bbk5, and i use MSI Afterburner and i OC at +135 Core and +375 Memory, in GW2 i get 60-70 fps in lions arch and dungeons and heavy active places but when im questing or doin chill stuff i can reach 90-95fps. My temp wise has never gone over 64C but i do have bottom cover off and i have a aftermarket gaming cooling fan pad for it.

Very nice. But you can push 660M further especially with your "special" cooling... Like +200mhz core and +500mhz mem. :cool:

Anybody realize that driver 310.90 - 314.07 can't be OC more than +135mhz? Only 310.70 and older version can. Hmmmm

Just 314.07. I'm still using 310.90 and OC's still good so far.

Yes apparently this is happening with the latest driver, that's why I haven't updated mine because I would like to keep my 1200mhz core overclock...!

I upgraded to get the benefits of the Crysis 3 improvements, etc.
Sadly I lost about 200 MHz of overclocking headroom, does anybody know if this was intentional by NVIDIA?

1250 MHz core really DOES make a difference. Big difference.

This thread has really helped me a lot. I have never overclocked before, and all of your posts help me successfully overclock my Asus G55vw for the first time. I used Asus GpuTweak and followed the +135/+350 and had about a 15% increase in performance. Thank you all again!

Here are my results following the information I obtained from this post.

Furmark Results: Stock Settings GPU @ 950mhz Mem Clock @ 2500 mhz (1920x1080 Full 15 Min Burn In)
17661

Furmark Results: Overclocked GPU @ 1085 mhz Mem Clock @ 2675 mhz (1920x1080 Full 15 Min Burn In)

Pretty nice gain for first shot at it. The temps didn't increase by much at all either.
