This little card blew me completely away I went from 575MHz stock gpu clock all the way to 700MHz. A phenomenal 125MHz increase on a little card like this is very impressive. After overclocking the GPU I was able to get an additional 71MHz out of the memory taking it from an impressive 1004MHz already to an even more jaw dropping 1075Mhz. It was at this point I noticed the temps jumping up between 53 and 56 degrees still well within limits in my opinion. At this overclock I did not run into any issues with display problems and was able to successfully complete the benchmark suite.
