I'm inclined to believe that nb and cpu-nb are the same default voltage, but will's statement that he phoned AMD is throwing up some doubt.
NB voltage is not on the CPU. CPU-NB / NB-VID is on the CPU. They are different places. NB voltage is the voltage supplied to a chipset on the motherboard.

It is not possible for CPU-NB / NB-VID to be 1.1v. See page 46 Look at S0.Cx.Px, min is 1.15v max is 1.3v. So it's variable, but it cannot be less than 1.15v. Read note 3 on the next page to see that VDDNB cannot be the chipset--

VDDNB, VDDIO, VLDT, VTT and VDDA. TDP is not the maximum power of the processor

Here's the way I get 3.8+


I go into bios and set my Bus to 262 x 14.5 or 19 x 200, then my Voltage to +0.175 and boot up!

Then I'm done!

CPU-NB is really 1.1V , CPU-NB is good setings for NB overclock, think, with 2300 withoiut more voltages, up 2400MHz give +0.1V at 2600 +0.2-0.25V and 2800 is a bot dangerous 0.3-0.45V. Max with air is possible about 2800-3000MHz stable, not more. Better for you, set about 2600MHz NB.
