Pentium 4 Northwood "B"

In mid-2002, Intel released a 133 MHz FSB (533 QDR) version of the Pentium 4 Northwood, designated as "B." It is available in speeds ranging from 2.26 GHz to 2.80+ GHz. If you have no interest in overclocking (which may make reading this book somewhat counterproductive), the Northwood "B" is an attractive chip given its ability to offer higher overall system performance due to its higher FSB. But for overclocking, the Northwood "B" offers a lower price to performance ratio than the cheaper Northwood "A," and is therefore not recommended for overclockers.
