Hi, I recently got a AMD Athlon 64 machine and installed Fedora Core 3 x86_64 on it. Things are beginning to
work fine now, but I'm unable to get the AMD Cool'n'Quiet functionality to work. I have updated to
Checked the kernel-2.6.9-x86_64.config from kernel.src.rpm to verify that the CONFIG_X86_POWERNOW_K8 is enabled. It is set to y, so I shouldn't need to modprobe the
powernow-k8 kernel module, as I was first thinking.
Also made sure that Cool'n'Quiet is enabled in the BIOS. I have an ASUS K8N-E Deluxe motherboard, following the manual I set the following:
Advanced->CPU Configuration->AMD CPU Cool & Quiet Configuration->Cool'N'Quiet=Enabled
Power->ACPI 2.0 Support=Yes
But my CPU fan is still noisy (btw, a Zalman CNPS7000B w/connected FAN MATE).
Where do I go from here? Is there a service I need to enable or something?
