Electrical Specifications
The processor core frequency is configured during reset by using values stored
internally during manufacturing. The stored value sets the highest bus fraction at which
the particular processor can operate. If lower speeds are desired, the appropriate ratio
can be configured via the CLOCK_FLEX_MAX MSR. For details of operation at core
frequencies lower than the maximum rated processor speed, refer to the Conroe and
Woodcrest Processor Family BIOS Writer’s Guide.

Clock multiplying within the processor is provided by the internal phase locked loop
(PLL), which requires a constant frequency BCLK[1:0] input, with exceptions for spread
