Why raise the Northbridge voltage?

[Queenz]

Here is a question I never asked before and I am just wondering about it cause it keeps bothering me. Why do you need to raise the Northbridge voltage when OCing your CPU and RAM?

On Intel CPUs and pre-A64s, the north bridge houses the memory controller

On your 478 setup did you have to raise your NB voltage to get that OC?

it made it stable @ 3.85, I only upped it to 1.6v though

 

rule of thumb on many 478 setups, AGP voltage=NB voltage

hmm...thats good to know for people that have intel based rigs

 

I never knew that, it might be because i have an amd rig
