Many of you may know I've been trying to overclock my E2140 on a 750i board recently. A big player in stability has been FSB voltage. I've never messed with a setting like this before. Really all I've ever bothered with is vcore and memory voltage, as I've always had CPUs with high multis that really didn't push the FSB that much (mostly AMDs, AM2 onward). My E2140 has an 8x multiplier, so it's taking a high FSB clock to really get it going. Question is: What exactly is FSB voltage? Which components are affected by it? How high is too high?
