Do you mean you are looking for the processor version string?  I don't 
see anywhere that is available over PECI.

 From PECI, you get just the CPUID dword which gives the extended 
family, extended model, family, model, and stepping numbers.

If you need the version string, it looks like it may be available in the 
SMBIOS tables.  Type 4 is the Processor Information structure which 
contains a string for Processor Version that our BIOS populates with the 
processor version string.
