I'm curious about what overclocks people have gotten with the power limit at default
How are some people actually adjusting the voltage on this card? I thought it was locked.
It depends on what bechmark or 3d app you are running... for example - on furmark, when set on 1600x900, no AA, it makes a lot of FPS, and it drains the power very much, so you hit the 100%, or even the 112% power limit. But when you set an AntiAliasing, then it makes less FPS, and drain much less power... in my case, with 8x AA, it drains about 60-80% power, so then you can have the power limit on 90% and it will not throttle down the frequency because of the power.. But when you add some clock frequency, the power consumption rises, but still, 100% target was enough to reach the frequency, where the card becomes unstable.
I found, that if I set temperature limit to 60C, then I can set a bigger offset for core and memory in some 3D applications.. I even hit a 2152MHz for a while, and if the temparature is below 60C, then the card is stable. When the temps hits the 60C, it lowers the clock frequency all the way down to 2088MHz, so thats the magic I guess... and in games, where there's not a very full load from time to time, then the temperature drops down and the frequency gets higher again.
-- but I'm having the most stable settings the same as @mrjosh86 have: +100MHz core and +400MHz on memory (core at 125MHz stable in most applications, but not all... and while testing 2152MHz, it was achieved with custom manual offset at 150MHz or 175MHz offset on 1081mV and 1093mV - the overvoltage has to be on 100% to achieve 1075mV or higher..)
