Setting for permanent underclocking

Thanks to Christine Tham for highlighting this. In paper, Core 2 Duo CPU is set for low power use and this results in lower clock speeds (underclocking). This can be improved by keeping processor permanently set at lowest clock rate. Currently, CPU does step up but is mostly at lowest level.

In section 4.4 (Power Schemes), just set Power Schemes to 'Portable/Laptop' with all else set to 'Never'. Windows sets CPU to permanently underclock. Note BIOS setting of 1.325V is not used and no BIOS changes are necessary.

Technical Background: this setting keeps CPU V-core (voltage core) to lowest level of 1.13V). This gives constant lower clock speed of 1.6GHz which means less RF radiation (& its harmonics) and uses less power. Previous setting has V-core between 1.15V and 1.28V with clock speeds ranging from 1.6GHz to 1.86GHz. You can see all this happening by installing supplied mobo 'doctor' utility (program installs as ITE Smart Guardian). No need for clocking utilities but if you want to confirm clock speed then use RM Clock Utility (see link).
