Display your CPU's true speed
Authored by: etyrnal on Jan 17, '04 12:53:52PM
is it possible that the 'speed' being reported by the System Profiler is not a MEASURED speed, but rather a speed that is being returned based on a gestalt ID... eg: maybe when the machine runs tha System Profiler, rather than actually measuring the speed, it just rely's on an Identification stored on the logic board... I say this because i do NOT believe that the System Profiler will report anything less than your machine's TOP-RATED speed... if you have a Powerbook that does cpu speed-switching while on-battery, then try this... Plug the machine into ot's Power Adapter and set the machine to MAXIMUM performance in the Energy Setting Pref Pane... (This should be the MAX cpu speed for your machine)... now run Sys. Prof. It reports your machine's Max Speed (the speed your Model was NAMED as) Now take your machine OFF wall-power by removing it from the Power Adapter and set your Energy setting to Low Power (if you have a machine that is capable of doing cpu speed-reduction it will drop to the lower cpu speed)... Then run System Profiler again... I guarantee that your machine STILL reports the HIGHEST speed... Because it is NOT measuring it... it is reporting the speed NAMED in your Powerbook's Model-Name... eg: an 867MHz TiBook is ALWAYS going to say 867MHZ even though it may be running at 667MHz..
