Hm, it is a 970FX @ 2000.36 MHz.
I'm confused that there is no smu?
Maybe this one lacks the smu. According to the docs I have, the 7,3 
behaves similar to the 7,2. And the 7,2/3 do not have an smu. The cpu 
speed is controlled via freq and volt. And some nasty gpio interrupts @ 
Nathan :) This bites me currently!

Can you boot this machine into OS-X and see what it tells you about the 
CPU speed?

Hopefully I'm wrong :)
