In myBIOS I have
setting, and a
do people change the [NB 1.8V] setting too?
Avoid setting this any higher than needed. It can take a tiny bump in voltage to help stabilize things but again, use sparingly.
I'd have to say an absolute max of 1.27v's or so is all you'd ever want to give it and I've also seen where several folks have stated it affected the IMC when it was set too high.
Be careful with that setting.
Your NB setting is the one you'd really want to change by bumping it up to the next voltage setting or so and see if it goes.
