So this is why it is necessary and strongly recommended to OC the NB when OCing in general, so you can increase the stability of your OC
See I think you are saying the same thing he said.
In AMD systems, the NorthBridge no longer communicates with the RAM or IMC. The "CPU-NB" does that, the Northbridge communicates with the rest. So when you increase the reference clock, you will want to raise the CPU-NB voltage if you become unstable, but not the NB (NorthBridge) voltage.
See my picture... Notice how the CPU-NB is in the same package as the CPU. I am not sure exactly where the HTT link connects in there(besides connecting the CPU and NorthBridge), but that is beside the point.Edited by fball922 - 1/22/11 at 3:36pm
