From the ACPI table, control method _PSS only contains two performance state
4GHZ and 1.4GHZ, so I don't see a problem here. My guess is that, there might
be a vendor driver for performance control under Windows?

This affects me too on M5A99FX Pro 2.0

Before fx8350 I had Phenom II X6 1100T on this board. All p-states were
detected. Now with fx8350 only two p-states are detected.
