Is running the North bridge core voltage at 1.748v safe/"not-bad-for-the-cpu-or-any-other-component"?

I don't even know what north bridge core is, but raising the voltage like that made my 4ghz overclock stable. xD

NB is the North bridge part of your chipset.

1,74V for Vnb is too high !!!!

Put 1,5V maximum and check your NB temp.

What is your NB temp ? (Everest or Bios can show it)

I was having a similar problem with an ip35-pro and this quad/ram. I had to put the northbridge up to 1.67v for 4ghz stable, which was max.

I don't know what process your Nb is made on but the p35's could handle a good bit of volts. The p45's went to smaller nm and didn't need much voltage. I would only risk it if your temps are good and you are willing to lose components, as with any overclocking. Ask "Is this couple hundred mhz worth killing a motherboard?" (or possibly other components).

Edit: Here's a similar thread about high nbv w/nvidia chipset.

Yes that seems high, just check your temps and if they seem fine then leave it.

To get 4GHz stable i need 1.4v for mine, this is actually the maximum voltage i can set and i need a fan directly lowing on it to keep it cool.
