    It is not games-related question but i hope someone will know answer to my problem.
    I have asus ASUS N76 R701VM-V2G-T5065V and i use Mathematica on it. It has nvidia gt650m inside so i'd like to use it for GPU programing, simulations etc. On specification is written it has 384 cuda cores, but when i start cuda in mathematica it said only 64 cores are visible?! :confused:
    I dont use gt650m as graphic card (there is some other in notebook, so that one is used as graphic card and i need gt650m as GPU only).
    So i dont get it, whats the problem? I'd like to use all cores...or at least 250-300 :)
    Can anyone plz help me!

    Sorry for bad english, I'm wake now almost 20 hours :(

    hummm... try to verify the drivers and all that.

    Aside that update the mathematica version that you use, it could be that they need a new update to properly recognize the new gpu

    Little (yours) and middle (up to desktop 680) Kepler only have very few proper compute cores.

    In fact its one of the worst out there for it.

    Thank you for such fast answers!
    It is brand new notebook so all drivers are latest and it is latest mathematica version.
    :((((( so is there anything i can do to improve performance?

    Off: I rly like this community :) Especially gaming section (i'm gamer since i was 6 years old) But now it's all about work, too little time for games.

    You can try overclocking it I suppose, but you have to be careful if you are doing important cad work.

    I don't know about CUDA but most things have a limit on number of threads, for example I have thousands (literally in clusters) of cores available, but I can still open at most 8 threads in matlab :( (damn licences)
