NOTES:
1.

Individual processors operate only at or below the rated frequency.

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 Intel

Pentium

dual-core processor E5000 series operates at a 800 MHz FSB

frequency (selected by a 200 MHz BCLK[1:0] frequency). The Intel

Pentium

dual-

core processor E6000 series operates at a 1066 MHz FSB frequency (selected by a

266 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
