Prolly so. Those C0's sure ain't no D0. There are some but it is rare. I am blessed as a vcore BIOS setting of 1.35 gets me 4.315ghz. Stressed in Prime95 I am at 1.27-1.28v with my 920. This is of course with Vdroop. Without I could get away with a BIOS setting of 1.28 or so. I think you should be happy with 4.2ghz.
