My CPU claims it is 2.53 GHz but never reaches it. I run CPU burner, and set c state limit to c0. All power savings are disabled and I set multiplier to 20T which is the only allowed turbo multiplier on throttlestop.
Maybe there could be another software for i5 which allows higher values? What is Intel trying to tell me by labeling this CPU as 2.53 GHz? so they they tested it with 2.53GHz setting and it doesn't freeze at 2.53 but they won't allow me to go that high? I'm guessing GPU is capable but the base clock is limited to 99.75 GHz by mainboard.
EDIT: I installed ASUS power for gear and it increased my FSB to 140 MHz (pretty great) Now my CPU goes up to 2.94 GHz. Problem solved
