    Unhappy Is this an incompatibility issue? Z87N wifi + Gtx 770

    I have a Z87N wifi motherboard from gigabyte and gtx 770 from inno3d.

    Z87N wifi is brand new and gtx770 is 6 months old.

    Whenever gtx 770 is on heavy load: laggy cursor, general stuttering, eventually freezes
    Updated BIOS, Nvidia drivers. still the same happens.

    Sent the Z87N wifi to manufacturer for testing. The conclusion was: no problem with motherboard. Problem with video card
    What they did was they put new gtx 9XX cards and there was no problem.

    Sent the GTX770 to manufacturer. Engineers say there was no problem with the GTX 770, they placed the video
    card on several testbenches and no problem was found.

    I sent the whole computer and they found out that the symptoms only appeared when my gtx770, specifically, is paired with ANY of gigabyte's mini ITX boards.
    I cannot have my items replaced since none of them is "technically" broken.

    The only reason could be compatibility and that is not handled by warranty. Is there anyone here who has the same problem with these items?

    PSU: 630W Thermaltake Smart SE
    CPU: i7 4770
    RAM: hyperX 8gig
    MoB: z87N wifi gigabyte
    GPU: GTX 770 inno3d
    SSD: Samsung EVO 840
    CAS: Corsair 380t mini itx case
    Monitor: AoC (1080i)

    Applications used: Benchmarking apps (3d mark, heaven) games: dragon age inquisition
    All parts are brand new, no overclocking

    Any other thoughts?
    What should i do?

    Welcome to the forum.

    What specifically is the "heavy load" that causes the problems? Gaming? If yes, which games and what in-game quality settings are used?

    Is your video card overclocked? If yes, what settings are used?

    What is the brand and model name of your power supply? How old is your psu?

    We don't know which cpu you have. Is the cpu overclocked?

    What is the brand and model number of your memory?
    How much memory is installed? Is the memory speed overclocked?

    Have you run any extended stress test to see if your system is overclocked?
    Have you run any graphics/gaming benchmarks and/or stress tests?

    We need detailed information about ALL OF THE HARDWARE in your system.

    We can best help you after you create a detailed hardware list in the System Specs
    portion of your forum profile at the bottom of the profile page or in your forum signature.
    Be sure to include brand names and model numbers.
    When you are done editing or creating your hardware list, save the settings.
