Voltage Help Asus M4A785T-M/CSM

[bhokuto]

Greetings, this is probably my second time posting?
I recently put together a system these are the main ingredients below:

Board: Asus M4A785T-M/CSM
CPU: Phenom II X4 955 BE
PSU: Antec 550W True Power
4Gb Ram DDR3 1333MHz Corsair XMS3

I forget the Header to get into these menus below:

Under 'CPU Ratio and Voltage':
Processor Frequency Multiplier = Auto
CPU/NB Frequency = Auto
CPU Over Voltage = Auto = 1.350 base/stock
VDDNB Overvoltage = Auto = NorthBridge 1.1 base/stock
Load Line Calibration = Auto

'Hyper Transport Configuration':
HT Link Frequency = Auto
HT Link Width = Auto
HT Over Voltage = Auto = 1.250 base/stock

'Memory Timings and Voltage':
skip all set to 'Auto' for the time being

'Chipset Voltage':
Chipset Over Voltage = Auto = SouthBridge 1.1 or 1.2 base/stock

Q&A
Which one is the NorthBridge?
What is the stock base voltage for each below?

CPU= 1.350
VDDNB = 1.1
HT Link = 1.250
Chipset = 1.1

Thank you kindly
