Hi all,

I'm currently working with some older desktop and mobile AMD K8 chips for a project and just wanted to know if anyone had any suggestions for software that could report whether Cool'N'Quiet and/or PowerNow! are supported?

It's enabled in the BIOS and I've made sure the power plan options allow the CPU to use it if it's supported.

CPU-Z doesn't seem to show any frequency or voltage fluctuations, yet CWID lists it as supported. Are there any alternatives to CWID?

Thank you.

Apart from motherboard support and a mobile power plan, K8 processors sometimes required a driver for these features to work in older systems. There was an AMD Processor Power Management driver for Win XP and Server 2003. Maybe try that?
