Help with Northbridge voltage please?

I have my E5200 clocked to 3.2ghz but I have decided to be a little greedy and try and get it up to 3.4/3.5 if possible.

Problem is I cant get it to run for more than a few minutes. It runs 3.1ghz on the minimum volts (1.125v I think) but to get to 3.2 stable I have had to go to 1.3v.

I was reading about upping the northbridge voltage which is on auto, but I cant find the default northbridge voltage for either the E5200 or my MSI P31 Neo2-FR Intel P31 motherboard so I have no idea what is a safe or normal manually set voltage?

I used to run 1.4V on my old MSI P35 NB, mainly to get 4 x 1Gb sticks of ram stable. Temps were fine with that.

Currently running at 1.28V but that's with a P45 board.

Is it just a case of knocking it up a notch and seeing if it runs stable, whilst keeping an eye on the temps?

I don't think NB volts are going to help.

You should stick with upping the CPU volts a notch at a time - up to 1.4v will be perfectly safe, assuming you are on air.
