Some people mentioned that, on some motherboards, the cpu vcore being linked to the northbridge (AGP/VDDQ) voltage? How is that possible?

Do they mean that increasing the VDDQ somehow invisibly increases the cpu voltage, even if the increase isn't shown?

What exactly does VDDQ voltage really do? I've heard it affects the northbridge, and something about CPU-Northbridge-Southbridge transactions...but how would that affect the cpu vcore?

(Note: plz don't say that increasing vddq will blow out current/recent AGP video cards..that's a myth as big as Texas....)

(it can cause harm to cards without their own voltage regulators, like the old Ti 4600's and R8500's, that dont use external connectors...)

Technical explanations welcome :)
BTW, board in question is an IC7/Max3.
