Check to see what vcore the Hardware Monitor in your CMOS (BIOS) setup shows.
I don't own an ASUS P5N32 E SLI 680
so I can't give you exact instructions, but you should be able to get to the hardware monitor screen by doing the following:
- Restart your computer and hit the <delete> key to enter the CMOS setup.
- Hit the <right arrow> until you get to the "Power" menu and select "Hardware monitor"
See if this agrees with what you are seeing in EVEREST and NVIDIA monitor. I think most folks here will say that what you see in the CMOS setup hardware monitor is the real deal. Some of the windows based monitors display incorrect values.
If the hardware monitor agrees that the vcore is still high, bump the setting down a couple notches, reboot and check the hardware monitor again to see if the change did anything. Remember when you make changes to the CMOS setup they don't take effect until you reboot.
