Divisors of 2 only work if the frequency can not be described with a 1 divisor.

I do not modify the bits [63:32] for the p-states. With above tables and the pattern i hope it's obvious how to define your own p-states.
Example:
p-state 0:
2.6GHZ 1.275V/1.1V
NBVID 1.1V 48h
CPUVID 1.275V 2Ch
CPUFID 2.6GHz 0Ah
MSRC001_00[64] Bits [31:0] 48002C0Ah
p-state 1:
0.8GHZ 0.85V/1.1V
NBVID 1.1V 48h
CPUVID 0.85V 70h
CPUFID 0.8GHz 40h
MSRC001_00[65] Bits [31:0] 48007040h
To apply it with RW-Everything use that script:
Note: The ">" must be in the text file.Code:>cpu 1 >wrmsr 0xc0010064 0x800001BC 0x48002C0A >wrmsr 0xc0010065 0x80000187 0x48007040 >cpu 2 >wrmsr 0xc0010064 0x800001BC 0x48002C0A >wrmsr 0xc0010065 0x80000187 0x48007040 >cpu 3 >wrmsr 0xc0010064 0x800001BC 0x48002C0A >wrmsr 0xc0010065 0x80000187 0x48007040 >cpu 4 >wrmsr 0xc0010064 0x800001BC 0x48002C0A >wrmsr 0xc0010065 0x80000187 0x48007040 >rwexit
Another Note: BKDG mentions that a NB DID must be the same in all p-states, as changing the NB FID requires an reboot NB frequency can not be modified via p-states.
