NOTES:
1. Individual processors operate only at or below the rated frequency.
2. Listed frequencies are not necessarily committed production frequencies.
2.8.2 FSB Frequency Select Signals (BSEL[2:0])
The BSEL[2:0] signals are used to select the frequency of the processor input clock
(BCLK[1:0]). Table 16 defines the possible combinations of the signals and the
frequency associated with each combination. The required frequency is determined by
the processor, chipset, and clock synthesizer. All agents must operate at the same
frequency.
The processor operates at a 800 MHz FSB frequency (selected by a 200 MHz BCLK[1:0]
frequency). Individual processors will only operate at their specified FSB frequency.
For more information about these signals, refer to Section 4.2.
