I recently overclocked mine 6490m with MSI afterburner. But I can't get the clock speed right (core and memory). I don't feel like playing around till I get 100% stability. Anyone mind sharing their settings? I'm currently using 840 MHz for core clock and 890 MHz for memory clock. Default is 750 and 775.
