    So i recently downgraded to a gtx 670 msi performance edition.
    Here is the problem -
    The gpu starts off at the appropriate workload for a task and slowly decreases the amount of processing power goes towards the task.
    For example - running a stress test will begin at 100% and slowly end up at 60% then crash out.

    I've tried reflashing the bios to the same one incase the current version was corrupt.
    Drivers are current and mobo bios also current.

    System is
    1800x
    X370 prime
    16gb corsair 3200mhz ram
    1000wpsu

    Have you experienced any similar issues?
    Have any ideas?

    What are the temps doing? Possibly throttling performance due to heat, might be time to re apply the thermal paste

    Temps are fantastic. Forgot a detail in descrip. The twin frozr fans have been replaced by 2 noc b9s powered by the mobo and a fan controller. 50 degrees max under load with as5 paste on chip

    How old is the PSU?

    It sounds like some sort of throttling

    Could also be a driver issue? Maybe try a previous or latest version to what you have?

    Did you use amd gpu before the nvidia one? Used ddu to clean driver?
    Also any background like msi afterburner?

    Not sure about this but might be a possibility maybe the card checks the RPM performance of the fans if they RPM gets to low the card gets throttled might be a case were its reading 0 rpm as no fans connected to card and decides to throttle the card even though temps are fine?

    use afterburner and force the fans at 100% then test. Temps may not be being reported correctly.

    That beong said 2 noc b9's are likely to overload the pwm on the board. Where do you think i should plug the fans?
    Ill try that

    No need to plug them into the cards pwm just plug the stock fans or similiar into the pwm that way the card is getting some rpm feedback from the fans. Personally I don't think this is the issue but worth ruling out.
