To enable the Cool ‘n’ Quiet feature on a Windows XP system, you have to change the power scheme. Open the ‘Power Options’ from the Control Panel. Choose the power scheme ‘Minimal Power Management’ and click ‘OK’ to enable Cool ‘n’ Quiet.
On a Windows 2000 or Windows ME system, an AMD Cool ‘n’ Quiet tab will appear under Power Options when the Cool ‘n’ Quiet software for Windows 2000 and Windows ME is installed. This must be set to “Automatic Mode” for Cool ‘n’ Quiet to be enabled.
I tried this on my MSI, and the MSI Core Centre CPU speed monitor reduced from 2411 to 1004 and the CPU core temperature dropped by several degrees in a few seconds !!
Yes, crosstrainer, I know that - but the BIOS setup screen is just on/off, it doesn't tell you to change the Windows XP power settings, does it ?
My motherboard manual just explained that it uses cool n quiet technology to reduce the processor speed when not being used - but it didn't say anything about going into control panel and changing the power settings. I had cool n quiet enabled in BIOS, but I had no idea it wasn't actually doing anything !!!
with vista as long as it's enabled in bios, just select 'balanced' from power options will turn it on. however the last 2 amd motherboards i have had it has been disabled in bios as it causes a major performance hit on quad cores, at the moment there are no quad optimisers so windows sort of alternates between the cores, causing then to ramp the power up and down which can seriouly effect performance on certain applications. if you want quiet you can enable 'q' or smart fan from bios. if you have c&q turned of it's also worth using an after market cooler imho.
