It is unfortunate to say that ATI has yet to adopt any overclocking features within their Linux drivers, where as Windows CATALYST has ATI Overdrive. An independent ATI Linux user had created Rovclock as a Radeon overclocking utility, but it is not actively maintained and is known to only support the older R200 generation GPUs. NVIDIA Linux users do have the benefit of using CoolBits or the open-source NVClock.
Today has been going well with ATI Linux, and no damaging experiences yet, other than the Fedora Core 5 installation conflict yesterday.
