    Hello and welcome to Tom's Hardware !

    To answer your question plainly, yes you're doing it wrong.
    I won't try to explain it all to you how to overclock an Nvidia GPU, because there are a lot of guides already on the Internet.
    But basically what happened is that your Nvidia Display Driver crashed because your GPU wasn't stable at a 955MHz frequency.
    You need to do some stability testing before starting to play. Also, the most important thing in overclocking is patience. Always increase the frequency by small amounts, then test for stability using OCCT GPU.

    You can take a look at this most excellent guide. Even though it's 2 years old the principle stays the same.

    You should also know that you probably won't be able to do any voltage tweaks.

    Good luck,
