    Default Slowdown to save power ?

    Guys,

    I have a x58a-ud3r with Intel 960 - this is used under Centos as a media Server - it has 8 drives in it.

    This box runs 24/7 in my house - i put my killawatt meter on it and it is using about 130w all the time - the reality is that it does very little on an ongoing basis - i would like to wind down the clocks on the CPU to try and save some power - i have set the BIOS to run the CPU at 1.6Ghz - but when looking in Linux it still thinks it has the 4 cores at 3.2ghz and the power useage has not reduced at all

    Any idea what i can do with this ?

    I am running FH BIOS

    Craig

    c1e and eist will be in the bios along with dvid which unlocks for adjustment when you set cpu voltage to "normal" setting,all those features allow cpu to downclock itself in speed/voltages when demand is low on the cpu

    Also make sure power mode in CentOS is set to balance or what ever is equivalent to Windows balanced mode.
