Slot A AMD Athlon Thunderbird CPU
The Slot A AMD Athlon Thunderbird was the first Thunderbird version made and released. This version of the Thunderbird was not meant to hit the retail market but to go to companies like DELL and Compaq to use with their Irongate motherboard these companies had already built for AMD systems but thanks to some cleaver sources we are able to get our hands on the rare Slot A Thunderbird. The Slot A Thunderbird is exactly the same as the Socket A version only it has been placed on the Slot A PCB for use on AMD Irongate chipset enabled motherboards. While the Slot A Thunderbird is not officially supported on the KX133 chipset many overclockers including myself have had success with getting this CPU to run on the KX133 although it can be a risky process.
