Default Re: Official "I just got a Geforce GTX 470/480" thread

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.
You will probally have to raise the voltage some when you get ready to overclock the memory so be prepared if it locksup, or crash, when you try to overclock memory.
