NOTE
Regardless of the DIMM type used, the memory frequency will either be equal to or
less than the processor system bus frequency. For example, if DDR2 667 memory is
used with a 533 MHz system bus frequency processor, the memory will operate at
533 MHz. Table 4 lists the resulting operating memory frequencies based on the
combination of DIMMs and processors.
