Real vCore voltages?

When I set my vCore to 1.3750 V in the Bios, it displays it lower in CPU Z, and jumps down to 1.296 V when running Prime95

When I set my vCore to 1.3875 V in the Bios, it displays it lower in CPU Z, and jumps down to 1.312 V when running Prime 95

The same happens when I set my vCore to 1.4 V in the Bios, it displays it lower in CPU Z, and jumps down to 1.328 V when running Prime 95.

Which is the real one? Which one should I be looking at when comparing to others' posted voltages? I see other people posting lower voltages then my D0 i7 920 while keeping stable, while mine isn't. Is this because I'm comparing their CPU Z result to my BIOS setting? Thanks

Also, recently I've needed higher volts to keep stability, why is this?

Thank you

no idea, on all of that, but maybe update ur bios? Seems like the first step to me.

It's vdrop/vdroop. It's normal. Don't worry about it. If your BIOS supports it enable Load Line Calibration, which reduces the vdroop/vdrop from BIOS values vs CPUZ values.
