Also for dual displays the Nvidia Display setting that get installed with Nvidia drivers is perfect except it has a problem writing a new xorg file. Permissions Nvclock I use to bump it up a bit These Nvidia 9600 based gpu can overclock very well 18% on this one and hovering at 55C when under full load Try different driver packages to make sure it is not the driver slowing down your computer I know that with the Cuda it saturates the gpu so that display becomes bogged Are you running science apps like boinc? If so shut it down and see. Make sure you run default speeds on gpu while trial and erroring Michael -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
