incresing the nb vcore

post #1 of 3
Thread Starter 
When ocing, when is the time to increase the north bridge vcore? And what about the south bridge vcore.

As a last resort to squeeze final MHz out of a system one can raise the Northbridge Vcore to see if stability can be gained. One must keep in mind that the Northbridge on NF4 boards run quite hot when not clocked higher so there should be good case airflow as even with the heatpipe solution there is a thermal radiation envelope that will encompass the chipset.

I personaly use this as a last resort, when I become mobo limited in the OC. For exmple if you have a CPU that easily goes to 222 FSB, no overvoltage, cool, the ram is stable, but @223 it simply doesn't want to boot most likely it's the mobo holding you back. This can be solved with a simple overvolt for the NB, a +0.1V can do wonders.
As for the SB, I don't see any point in overvolting it. I don't think it helps the OC, you just risk toasting it since on most mobos it doesn't have heatsinks.
