Is there a way to downclock my CPU when idle?

[liamcrane]

Hi all

Just wondered if anyone could maybe help me out, I have a PII x4 955 chip and its OC to 3.7ghz on 1.40v. I was wondering is it possible to setup my CPU to downclock when its left idle? Im doing some testing on my machine for my BB connection at the mo and my rooms quite warm so would like to run it a bit slower to save its life span a bit as well. I dont really wanna keep changing it up and down in the bios everytime i boot up, i do have the cool and quiet feature on my board but i have heard it to be a bit funny when enabled on an overclocked chip

Hope you can help

Many thanks

Cool and Quiet works fine with my X4 640 when overclocked.

Might enable it in the bios then and see how it goes for a couple of days, cheers for that

Also make sure your windows power profile allows for min 5% CPU usage when idling and not 100%

"Balanced" power profile in Windows 7. "High Performance" will force full clock. If your Asus board is anything like mine you'll have to use voltage offsets rather than whole numbers to get C&Q working with your overclock

I use PhenomMsrTweaker, allows for more finer control and a lower vCore.

I use K10Stat to get full control over every p-state's voltage, frequency, and at what load level it kicks up/down. Uses a mighty 0.75V at idle

(I also have no issues whatsoever with leaving CnQ on - with a BE you shouldn't struggle. I suspect with a non-BE where people have to change the base frequency, what happens is that their idle state ends up around 1-1.2 GHz, which can't be done at the default idle voltage.)
