    On a scale of 1-10, what is the chance I'll kill my GPU?

    I normally run an OC of 648/1620/949

    How likely will upping the VRam to 999 kill it?

    Its going to get hot, I bet money your memory wont stay at 999 either. It will freeze from an error or restart your drivers throttled down. Your normal overclock in fine IMO. With overclocking there are three things you must stay aware of. 1 Voltage, you dont need to worry about this since it cannot be changed here. 2. Frequency, you want to find a frequency that dosent cause a bunch of errors and then back donw a bit to be safe. Heat, as long as you arent spiking 90 C constantly you should be fine here. Although I have heard the temp reported for the GPU is only the core and not the memory, I dont know about this myself, but I figure if your memory is getting hot (90+) it will cause you core to be hot as well. Other than these things overclock to your hears desire.

    speaking of which [@Infiniteone], are you stable gaming at 700/975/1805 OC or is that just for benchmarking purposes?

    I've found that i can stably game without driver crashing to desktop/artifacting at 700/950/1750 OC with 190.15 drivers.

    1, you wont kill it because it will downclock before it harms itself.

    I killed mine the fan quit 4 mo ago it shut down several times and quit completly this month. It has been found that the life of a light bulb run at a different voltage is Lold/Lnew=(Vnew/Vold)^13.1 processors use a simular equation you are really shortning the life of processors running them hot.

    I'm always wary of overclocking memory too much because you can have acceptable temps and still fry the card because the temp sensor only shows the core.

    Yes if you are running them hot this is true, Now think about this. If your GPU will climb to 80C and the fan will work at 90% to get it back down to 70C then overclocking your GPU would result in making the fan work at 95% to get the temp back down. It sounds to me like you had a crappy fan is all. Dont scare people away from overclocking. Plus there is no voltage changes being made here.



    Yes I agree dont O.C. too much I dont think 950Mhz is too much myself.
