Yes it is the Multiplier for the CPU.
NB FID = North Bridge Frequency.
CORE FID = CPU Frequency.
NB VID = Northbridge voltage.
Core VID = Core voltage.
For frequency 14x = 0c 14.5x = 0d 15x= 0e and so on.
For voltage it seems to work in reverse so the higher the hex number the lower the voltage. 14h = 1.288 and 16h =1.264 etc.
The Following settings will give you 3.2Ghz at 1.325 volts (approx) which is probably a good starting point.
