Unfortunately, EVGA and Gigabyte boards have sloppy Vdroop characterisics, which makes overclock stability more difficult to achieve. Although I've been very impressed with these boards for their excellent features, sloppy Vdroop has always been the deal breaker. If you watch the Vcore signature in SpeedFan's "Charts" at idle, then run Prime95 Blend, you'll see just how bad it really is, which can exceed 64 millivolts. Each negative spike represents a potential BSOD crash point. When enabled, Load/Line Calibration can help to maintain an unchanging Vcore (little or no Vdroop) during fluctuating loads. The Asus boards will typically hold Vdroop to the bare minimum at only 8 millivolts, due to better voltage regulation.
