3950X : CpuPwrSampleTimeRatio = 0

Hello,

Using a Ryzen 9 3950X ; calling CPUID Fn8000_0007_ECX[31:0] to read CpuPwrSampleTimeRatio returns zero

Thus the following formula from the Architecture Programmer Manual can't be applied:

N = CPUID Fn8000_0007_ECX[31:0]

PwrCPUave = N * Jdelta / (Ty - Tx)
