--- Comment #16 from graham grhm.perry@gmail.com ---
Windows has a very different implementation at the moment, but uses the tables
in a similar manor.
From what I can tell, it uses a method very similar to dynpm, but it uses it to
switch between the fixed modes in the bios tables. I haven't seen it ever break out of them and start setting engine clocks and memory clocks independently. Maybe you have access to documentation that shows otherwise though?
