uAMDtool integrates an accurate AMD Quantispeed PR rating calculator with other commonly used AMD-based tools.
The Quantispeed calculator has full support of Morgan, Palomino, T-Bred, Barton and AMD64 processors, and fully supports overclocked front side bus speeds with unrivalled accuracy for all modes.
Added is a CPU stepping decoder which lists all known details about your specific CPU, a full list of stock AMD AthlonXP and Athlon64 settings so you can see how much performance youre gaining from that higher FSB, and a clutter-free small version which can be invoked from the command line or from the main interface.
