Better Late Than Never ...
I've got to admit it, this article is rather late. Tom's Hardware has the knowledge of how to change the core clock of an Athlon-processor since this new and powerful AMD-CPU was released. As you might remember from the
Overclock Using the Internal Connector of Athlon
Most of you know it, Athlon's clock speed can be altered via its internal 40-pin connector.
You will have to open Athlon's case to get to the internal connector. Opening the CPU-cartridge is done by C_A_R_E_F_U_L_L_Y preying the plastic cover from the aluminum heat plate. It's best to use a knife with a large and very sturdy blade. Be careful that you don't destroy any of the parts inside the cartridge! The plastic cover is connected to the heat plate with four little metal pins that stick inside little notches inside the cover. It's very similar to opening an old Pentium II processor cartridge. Three of the pins come off very easily; the fourth is a tough one. In Athlon's case the tough pin is in the lower left corner when you look at Athlon's plastic cover so that you can read 'AMD Athlon Processor'. It's the opposite side to where you find the black plastic 'AMD'-insignia.
