Strategy

The Athlon Thunderbird 1333B offers essentially the same overclocking potential as its 1200-MHz sibling. As with every processor, the Thunderbird displays a maximum point of return, above which it will begin to offer less and less. Expect results in the 1400 to 1500 MHz range. Additional scalability is possible with extreme cooling techniques, but most units reach their limits around 1600 MHz.
