voltage

do all gigabyte mobo's have a 1.55v limit on the vcore. i cant go past 2.8ghz stable need more voltage.

AFAIK the S4 is a low end board that's probably why. And if your on air....


1.55 = too much.



Oh and just letting you know that PSU will probably kill that rig anytime soon so get a proper one. (that's probably limiting your clock too)
