Our pals over at ZDNet Germany have released an overclocking tool for the Mac Pro and Xserve that raises the speed of the processor, front side bus and memory – all without opening the case. Although tons of overclocking tools are available for Windows, up until now, little if any have been available for the Mac OS.

Overclock Ati Graphics Card

If you have ATI chipset, then you don’t need any other overclocking software, just download ATI Tray Tools and you should be good to go. It is a very tiny overclocking software that works only for ATI chipsets.

'ZDNet Clock 1.0' for Mac OS X supports the Mac Pro and the Xserve and requires an Intel processor and Mac OS 10.5 Leopard. More information and test results from three Mac Pro models is available at ZDNet.de.
