The System tool in Control Panel uses currentspeed to do its reporting rather than maxspeed, but the System tool may display the wrong clock speed for the Central Processing Unit (CPU).

As of January 2002, Windows XP uses the currentspeed value rather than the maxspeed value because the maxspeed value was reporting inconsistent values.

After startup, the processor may not correctly reflect its correct speed until a program utilizes processor cycles.

The computer basic input/output system (BIOS) in some laptop computers may throttle the processor because of heat, load, power AC/DC. (more…)

As with XP, in Vista you can speed up performance by sacrificing the visual effects. Go to the Control Panel, System and Maintenance, System Properties, Advanced (Tab) and settings. Set the radio button in ‘Adjust for best performance’.

This may produce a marginal improvement on a low spec machine, but it I could not detect a faster response on a machine with a 1.2 Ghz processor and 2GB of RAM. In truth, I was under-whelmed by this Adjust for best performance. A better way to truly speed up your Vista machine is to buy a 1GB USB RAM stick and use Vista’s ReadyBoost feature. (more…)
