Here has ocinside.de already exemplarily in very good workshop manuals what is to
be done.

The processor multiplier in the Bios cannot be set on some Mainboards more than 12.5
Why ? 
This is not supported by the processor CPU Socket, there is 4-bit FID and 5-bit FID
support, depending on what the Mainboard manufacturer applies.

Unfortunately, there is not a specific list for Mainboard with 5-bit FID support.
