When AMD rolled out its Spider platform in November, one of the platform's selling points was the OverDrive utility. The tool acts as a virtual Swiss army knife of overclocking tools, but AMD didn't make it available directly from its website, forcing users to hunt the tool down on Google or other sites instead. Today, AMD tells us it has made the latest version of the tool available for download directly from its Game website, alongside graphics cards drivers and other goodies. OverDrive can be downloaded from this page. Although the file not directly hosted on AMD.com, AMD provides download links to mirrors on Asus' website and TechPowerUp.
As we explained in our review of AMD's 790FX chipset, OverDrive regroups a wide array of overclocking, tweaking, and monitoring tools. Users can overclock their processors (with separate speeds for each core on Black Edition Phenoms), tweak their memory settings, test for stability, and run benchmarks. A somewhat cheesy video that highlights the various features of OverDrive can be viewed on this page.
Incidentally, the OverDrive tool is the only officially sanctioned way to disable the infamous TLB erratum fix, which adversely impacts performance in many tasks. To toggle the fix off, users must click on the "turbo" button at the top right of the OverDrive screen. "Yellow" and "red" settings mean the patch is disabled. Only 790FX motherboards are supported, however.
