Appendix
CPU Clock Speed Provides limited capability to adjust the CPU clock speed so that the CPU
operates at a different frequency than that designated in the manufacturer’s
design specifications.
NOTICE:
Dell does not recommend operating the CPU at a frequency that
is greater than the manufacturer’s design specifications (also referred to
as
over-clocking
). Operating the CPU in this manner may cause your
system to shut down unexpectedly, may result in a loss of data, and may
reduce the operational life of the processor. If the system shuts down
unexpectedly or is unstable, select a lower CPU operating frequency.
