help cpu not utilizing 100% speed

I have my cpu oced to 3.3ghz, when i check in cpuz it says 2.4ghz even when im running orthos or prime95. I have minimum cpu usuage to 50% and maximum at 100% in windows power settings and know this is the cause of my problem. I dont want to set the minimum to 100% because of thermal issues, is there anything else I can do to force it to utilizie all 3.3ghz when running cpu intensive programs and then underclock itself when idle or using less cpu intensive software? Thanks in advance.

He has a different problem. Speedstep should not be active when he's running orthos or prime95. Try TAT and put your throttle to 100%. It should run your CPU at 3.3Ghz.
BTW, you should not run your cpu clock this high if you have heat problem. If the cpu temp is too high, it will throttle back and makes the overclocking not worthwhile.
