I resume my PC settings:
i7 5930K, Asus X99 Deluxe, 0904 BIOS, Windows 8.1
stress test, AIDA64, Prime 95 28.x for no more than 30 seconds, x264, 3d mark.
4.2GHz 127MHzx33 (using XMP Corsair Vengeance LPX 2800MHz 2800MHz)
vcore 1.180V, cpu input 1.89V, LLC7 -> windows does not boot
vcore 1.200V, cpu input 1.89V, LLC7 -> system hangs immediately on stress test
vcore 1.220V, cpu input 1.89V, LLC7 -> system hangs immediately on stress test
vcore 1.250V, cpu input 1.9V, LLC7 -> system hangs on stress test after a while
vcore 1.270V, cpu input 1.9V, LLC8 -> it seems stable, (AIsuite reads 1.280V)
what should I do, what I'm doing wrong?
temperature are not a problem, with H80i the hottest core does never exceed 65°.
