Will be testing this RSN.
Can you provide more information on where you think you are getting the GSF values from? I am not aware of such information.
The internal documentation always only refres to the minimum VID/FID values from the MSR. Also, according to the specifications of all C7 models listed, there are some that require a minimum of 400MHz, others require a minimum of 800. I have not found any that would require a minimum of 600MHz.
So I don't really know if your system really operates outside any specified range.
The only thing I know of that you can read from the CPUID vendor string is the maximum clock frequency in ASCII.
So it seems, e_powersaver is not really at all as dangerous as it appeared!
