I've noticed in hwinfo64 in the sensors page is V1 and it looks to be one of my vcore settings because it is the only sensor that drops to like ~ .8 volts at idle and way over my set vcore at load. For example my vcore in bios is set at manual static voltage of 1.261, and on the core sensors it goes to 1.28 which is fine because my mobo overvolts a tiny bit. but on this V1 sensor it goes up from .8 idle to 1.36 Vcore!!!

I've googled this V1 readout and I found maybe 2 forums that really did'nt answer the question what is V1. One website I think the author said to ask Asus.

In the attachment pic you can see v1 sensor under the Asus EC: Aii section.

All c-states and speedstep are disabled.

Im just concerned of that sensor because I can do 4.9ghz stable on my haswell at 1.315vcore the cores go up to 1.344 but this v1 sensor says over 1.4 volts at this setting.
