    Hello guys! Some trouble im having while ocing.

    I have this EVGA GTX260 216 for about 3 month and it has been great to me. Yesterday i pushed it to 700mhz core using EVGA Precision. After some gaming, i started noitcing snows and freez and then it was fine again, but my frame rate decreased dramaticly. Back out to windows, i see that my core is caped at 400mhz no matter what the number i set it to, not even reset to default would help. Only if i restart the computer will return to normal. Is this a fail safty feature build in on the GTX200 cards? kind annoying if OC fails, i wonder if there is a way around it.

    Mine did this just the other day while playing Call of Jaurez but it was really hot in the house and my card got up to 74* which isn't normal for me. Heat issue maybe, never did it before and hasn't since.

    Yes, it is a built-in safety feature of your card that is shutting it down to "safe" operating levels!

    With past generation hardware, users eventually learned to recognise when their cards "Throttling" safety protection was kicking in because of too much stress (overloading/overtemping) on the GPU and/or Memory chips. Typically happened because of a combination of overclocking too far and poor temperature control. Was usually cured on a card by card basis by improving the cards heatsinking and limiting max overclocks to around 5-10% below the levels that artifacts were observed?

    It is most important to understand that as you increase your cards overclock levels you are in effect at the same time reducing the Overload/Temperature Point at which the cards built-in safety protection functions will kick in.
