Disabling cpu core

Hi All

Just want to ask if its ok to disable other cpu core for a dual, tri, quad or hexacore cpu? The purpose will be is to save energy when I leave my PC on when Im downloading stuff from the net. Has anyone tried it? any negative effects on the cpu? Any useful link regarding this will be very much appreciated.

The cpu im currently using is the Phenom II X6 1090t.

thanks in advance.

    If you have cool n quiet enabled, your looking at only a few watts difference at the most since it's idle, there is also no way of doing this that I'm aware without going into the BIOS.
  2. Dont buy a 6 core if your worried about energy.

    thanks, yup there is an option in the bios. im not sure though if it will have any negative effect on the cpu.
  5. The 6 core PII uses about the same amount of energy as the PII x4 due to a more efficent architechture.

    1. Cool & quite will lower the voltage and clockspeed if CPU demand is not much thereby saving energy.
    2. Set your power setting to "Turn-off Monitor" after 5 minutes so the PC shuts off the display. save on monitor power too...

    If you got an old rig with dual core, might be good to put it to use for your downloading...
