  1. Keep going until it crashes in games, then turn the settings down a little, its as simple as that. Its voltage locked so don't worry about the voltage slider, it doesn't do anything.
  2. In msi afterburner or EVGA precisionX, if you can go 150 power target doesnt mean your card can handle it, follow this process: Setup your fan High or a custom fan curve so your temp stays within 80c then increase the power target from 100 to 120 and then increase 20mhz or 30MHz more base clock and 50mhz more memory speed. Play highest quality games an hour, if its stable then repeat the process till its not, then again increase the power target 10 more if still crash than 10 more if still crash than go back to last stable overclock, from their you can try push more by increasing the memory 50MHz or 100MHz more if it doesnt crash fine or go back, thats your cards best overclock. Every card even same chip/make oc different. Remember kepler boost is auto based on thermal , power & Base clock. There for say if you can do 1100MHz base in real gaming time it might bosst to 1300MHz+ provided your card can handle. heres one example http://www.legitreviews.com/article/2023/13/

    I tried tht it only goes up to 40mhz on the core and 40 on tge memory is that normal?
  4. You just got unlucky by the sound of it. Overclocking is never a guarantee.

    ok so i tested my overclock which was 40 and 40 mhz and i ran heaven and it was good but i only ran the benchmark that is like 4 mins long is tht fine? ok i shouk run some other stress tester
  8. Furmark doesn't work as a stress tester for Nvidia cards because theres a driver profile for it that stops the card from clocking to full speed when the program is open. Run something like Unigine Heaven 3.0.
  9. +40 MHz is not a bad overclock since you already have a factory overclocked SuperClocked card.

    If you are using Afterburner, you can stress test on the Kombustor application which is usually installed along with it.

    Here's a good overclock guide for GTX 600 series cards.
