Overclocking - AMD's OverDrive Badly Supported
There are two ways to change the multiplier to overclock the processor. The classical approach would be to go through the BIOS, which requires rebooting the system whenever you wish to make any kind of change. The second option is to use AMD's OverDrive tool.
AMD's OverDrive tool
You can download the OverDrive tool from the motherboard manufacturers' support websites. Although AMD has an info website for its tool, there is no download link. There isn't even any information regarding the latest version of the tool.
It is up to the motherboard makers to test new versions of the OverDrive tool for compatibility with their products, and offer them for download on their websites. The upshot is that there are many different versions of the tool floating around the Internet. During the time we ran our tests, we found various versions of the OverDrive utility on the support sites of ASUS, MSI and Gigabyte.
