How do you unlock the multiplier on a new AMD Thunderbird and Over-Clock it?.... "On the top left of the PCB, you can see the Gold Fingers. We also used a rather large Global Win Heat Sink and Fan combo with decent thermal paste joining the two. On the right is the full setup with the Afterburner installed. We used the GA-7VX Motherboard's ability to change the Front Side Bus speed and dialed in stable at 115MHz. FSB. The Afterburner allowed us to run at a multiplier of 7.5, only a half step higher than the stock multiplier. However, this was the highest speed at which the processor would run stable with our standard mainstream cooling solution. The voltage was dialed in to 1.85V which seemed the best level for stability."
