Question about NB voltage

post #1 of 8
Thread Starter 
My motherboard isn't exactly a high end model and the bios reflects this; There are only 5 options for NB Voltage in the bios: Auto, Low, Medium, High and Highest. My question is: Which option should I set it to to get the best overclock without destroying anything in the process?

Since it only gives you those options I'd try setting it to medium and check the voltages in AIDA64, from my experience you shouldn't need to go over 1.55v for a good overclock, though that was on my 780i board.

Also you might want to upgrade your heatsink if you're overclocking.

If you are unable to monitor NB voltage amount via software or BIOS readings, leave on auto to be safe.
I say safe lightly, as auto tends to overvolt a tad.

Where is the NB voltage in AIDA64? Mabye I am being blind but I can only see CPU core, GPU core and the power rails.

It should be in the chipset section of the motherboard tab IIRC, then at the top you should be able to choose sb or nb.

Just out of curiosity, if I do leave it on auto does it actually automactialy change the voltage to what the system needs, or is it just a preset value that 99% of the time works fine with most hardware?

If you choose auto it usually works on smaller oc's.
But it is limited by BIOS version.
ie: auto NB v works up to 4GB "for example"
then above that you need to manually up the voltage.

It can't be forever increasing automatically as you increase clocks,no.
It is limited in its auto increase to protect MB.

Unless I am reading this incorrectly, the voltage values for Auto, Low, Medium and High all seem to be 1.125v. Hmmm... I may leave it on Auto, like you said, just to be safe.
