Biostar V-Ranger
Biostar supplies their own overclocking tool called V-Ranger on the accessory CD. It doesn't seem to be available for download off the Biostar website.
As you can see the asia-style user interface is not very intuitive to use. Text labels that show what the functions do are not available. However, you can get a mouse over tooltip which lets you guess what the settings does. Biostar also included a "Find Max" method which is not working that great even though it uses a furry cube which is obviously
stolen from inspired by ATITool.
However, once you get used to the tool it is fairly easy to do and gets the job done well.
