|I dont know...why not? lol|
I tried Rivatuner but i like the Nvidia control panel better...i can test each time i change the clocks, dont see where i can do that in Rivatuner.
IF i move the core clock to 720, id have to put the Shader to 1800, to stick with the 1:2.5 ratio (and Rivatuner confirms this ratio)
moved to 690, 950 and 1725 for the moment. Got a 26412 3Dmark score with that setup. Although my nvidia system monitor shows it at 685, 950 and 1700
