    Hmm, do you have proper drivers installed? Did you click on "show overclocking"?

    304.79, yup clicked, it's just not possible to click on unlock max or unlock min, it's greyed out, can show you screen when i return home. I think +135 MHz is set limit, don't 650M have the same problem and the limit was removed by modded vbios?

    Lol, the 650M is a non-MXM part, so it should be very hard to mod the vBIOS to do that. Moreover in an apple laptop :p (mbp retina)

    The 660M though has a dedicated BIOS chip that isn't tied to the system BIOS. Modding would be easier than the 650M.

    Hmm, that's strange, normally the "unlock max" always works, weird.

    Aw man, that sucks.

    Try using MSi afterburner and EVGA precision.

    If that doesn't work I have to consult Guru3D forums, which will take a while...

    @_@

    EDIT: as a last measure, try the beta drivers too http://www.guru3d.com/news/nvidia-geforce-30479-beta-download-/

    Make sure you use the "complete wipe" method instead of juts running the nvidia installer

    I am using those Beta Drivers already, installed them just after clean windows install. I tried both EVGA Precision and MSI Afterburner before also.

    Aw man, I guess I'll head over to Guru 3D and see what they can do about the RivaTuner software

    EDIT: Try this: http://www.overclock.net/t/1267918/...-disable-boost-fixed-clock-speed-undervolting

    Instead of typing: nvidiaInspector.exe -forcepstate:0,2

    Type: nvidiaInspector.exe -forcepstate:0,1

    Not worked same as described there, because I couldn't get memory clocl more than stock, but i increased core much higher :
    NVIDIA GeForce GTX 660M video card benchmark result - Intel Core i5-3210M Processor,LENOVO Product Name score: P2949 3DMarks - 1200 MHz Core i 1250(2500) MHz Memory.
    NVIDIA GeForce GTX 660M video card benchmark result - Intel Core i5-3210M Processor,LENOVO Product Name score: P3019 3DMarks - 1230 MHz Core i 1250(2500) MHz Memory.
    I also needed to type "forcepstate:0,5" otherwise it didn't work, because it's this "P5" am i right ?

    Sorry for not understanding, but I'm happy for you that you can OC higher than before

    Once again, sorry, I don't have the 660M/kepler based card lol :p
