June 28 - 4:10pm EDT   ZDNet has announced what it says is the first tool for overclocking the Mac Pro. Windows options for overclocking are prevalent, but none have been available for the Mac Pro, according to ZDNet. It claims that the new software, called ZDNet Clock, is capable of speed increases of 15 to 20 percent, and most computers with 2.8GHz chips should be able to meet or exceed 3.2 GHz. The version 1.0 software supports Intel processors on a Mac Pro or Xserve and requires Max OS X 10.5; it is available for download now, free of charge. [full story]
