However I don't know any "normal" overclocking range for the memory, don't know if the stock 1848mhz are already quite close to the limit, so what is a healthy and secure overclock for that one on the GTX 480? 1900,1950 or 2000? Is Furmark/Kombuster a good app to test memory for overclocking artifacts?
Since I wanted to take it safe with the quicktests I forced the fan to 100%, temps didn't break 63C with Kombustor.  |
I've done some testing using Heavn 2.0 with 800/1600 and memory at stock, 1900, 1950 and 2000, and there's very little difference in FPS. With extreme tessellation and max AA at 1920x1200, average FPS ranged between 54.1 to 54.6, less than .5 difference, and 2000 sometimes gave me a slightly lower min FPS compared with 1950.
