Let windows idle and right click on my computer and if your cpu is @ 1ghz or 800mhz then C&Q is enabled. I have recently started using it again and its great.
All Athlon64, Opteron, Atlhon64 X2 and Athlon64-FX are supporting CNQ.
There are Semprons s754 that are supporting CNQ. I am not sure, but I think all models above 2800+ and Rev E3 are supporting CNQ.
You don't need the BIOS to disable it. Uninstall the CNQ driver and will be dissabled.
