Ive read through everything and i kinda explained it wrong, i have no problem leaving it as it is.. but its always on, doesnt genarate to much heat, its using a Zalamn 7700 cu, i also have an exhaust fan as well so its stays cool, like i said before this is hooked up to my Tv downstairs and i just watch films of it and things like that pictures mp3's that sort of thing.. it doesnt require much proceesor power to send these over the wireless connection, so if i underclock it, would just be more effiencent... but what im gettin at alos is if the power is required it will automatically go to its stanard clock speed... a lil like my dell laptop it has a 3.2 ghz p4 processor init but maximum it runs at is 2.6ghz coz it never needed all the power!! hopefully that makes more sense edit: i was just playing around with my bios settings and discovered something wierd maybe its me or .... if you look on the image below it shows my core voltage as 2.8v but in the bios it says 1.4 any ideas any one
