Ok peeps, I got a QX6700 quad core 2 - anyway this is the question which I am curious about... :eek:

I tend to leave my computer on as I remotely access it a great deal - and run it as a server - however I don't use the full processing power when away, and therefore leads me to this question:

Would it consume less electricity - as in lower electric bills if I under clock it to say 1.6ghz as opposed to its normal 2.6ghz?
 
well of course it would. it's doing less working. the question is, why would you want to? and more to the point, the money saved on electricity < the cost of the quad-core over a slower dual core.
 
I think the speed step would automatically lower the voltage and the clockspeed to 1.6Ghz when you are not using it anyway. Just make sure the option is enabled in BIOS.
 
Thanks for the response :)

Reason I ask this question is when I'm at the computer i need every bit of computing power, but the times that it sits idle for just disk access I want it to be economical. True that a dual core would be less power hungry, but I wouldn't have bought a quad core just to undermine its potential - so again I repeat - this is for when I'm away from my computer.

The CPU is sitting in a Gigabyte DS4 at the moment - so I have only seen ways to have it auto OC but not to use speedstep, unless I'm missing something... so any ideas where in the DS4 bios this is, since I have looked at all the options, but "speedstep" is not mentioned anywhere :(

Any ideas?

Think it's under the name "ESIT" or something like that, by default it should be on, otherwise go into CPU configuration or similar menu.

Best way to check in windows is to use CPU-Z to check the clockspeed.

Interesting you say that, when I had version 1.38 it always reads 2.66ghz always, then i installed 1.39 and no matter what load i put on it, it reads 1.66ghz which is weird. I thought something must be wrong with version 1.39 so I went back to the older version.

I will look for that EIST option when I get home :) thanks
