"Overclocking the 65nm AM2 X2 5000+ was an interesting experience.
I managed to get it running with FSB speeds as high as 345MHz - but
only with significantly reduced multipliers. In order to get the best
possible balanced score, I spent a lot of time trying different
multiplier and FSB combinations, and frankly my experiments were made
needlessly frustrating by the unpredictable ways it would choose the
memory speed dividers."
