Overclocking AMD's Thunderbird and Duron Processor

Overclocking Duron And Thunderbird - The Theory

Quite a few weeks ago we were in the lucky situation to receive the full data sheets of 'Thunderbird' and 'Spitfire', today known as 'Duron'. In those data sheets we found the following promising data:


Well, it's not too hard to see that this is the list of all 'multiplier' or 'clock divider' settings for Thunderbird and Duron. The pins FID[0-3] are obviously responsible for the multiplier used by the processor. Thus finding the pins would mean finding the way to overclock those CPUs.

Now obviously it's not too hard to do so, since the data sheet naturally contains a description of each CPU-pin. This is where they're at:


Unfortunately locating the pins alone doesn't quite settle the story. You need to find out what to do with them. The following information helps us with that.
