I overclocked my thunderbird 700 some time ago, and was only able to get it to 800 no matter how high I put the voltage. It runs stable and cool with my Chrome orb and case fans, but I just thought it should go faster, I unlocked it, and it just won't go. I've read of thunderbird 700s going to 1 GHz so I was hopeing for 900 or at least 850. Any clues on how I can get more speed without messing with the FSB? I have the asus A7V mother board with generic PC133 memory, I was also wondering if the memory could be the problem.
