This has taken me hours upon hours of testing.
Regardless of what's said, 4GHZ on the new C3's is NOT easy, my C3 will go 3.9GHZ IBT stable at 1.375 Vcore, but this took forever, I'm going to work on trying for stability at 1.45V tomorrow.
I'd like to thank Gareth for his overclocking thread, and the people who go "Oo your overclock isn't stable unless it's LinX stable, or IBT stable"
Well here it is dammit!
