CPU capabilities

For the definitive information, get the appropriate data sheets direct from Intel - don't believe any postings on the internet.

Aside from software limitations, additional limitations may be imposed by the support chips.  Just because a CPU will operate from limits A to B doesn't mean you can actually exploit the CPU that way - all the other parts of the system will have to allow you to do so.  So aside from looking at the Intel data sheets for the CPU, you need to look at the specific construction of your system to find out whether the CPU itself or an external support chip controls the core voltage and frequency.
