Not sure what the CPU voltage actually is

[Linux_Geek]

I was trying to overclock my i7-4790k, so I set the core multiplier to 47, the cache multiplier to 40, the Vcore to 1.3 Override, and the cache to 1.2 override. When I turned on Windows and opened programs, CPU-Z said that the voltage was 0.952v. AIDA64 told me the same thing, and when I did all kinds of stress tests (Prime95 small FTT and large FTT, Aida64 stress test, CPU-Z stress test) the voltage stayed the same. I'm assuming the override setting worked, but it's not doing the right voltage. All of the programs said that the processor clocked up to 4.7 while at 0.952v, so I'm very confused.

If it helps at all, Speedfan has a bunch of numbers:
Idle

Prime95 (Large FTT)

EDIT: Ohhhhk so I just reverted all the settings to stock and I'm getting still the 0.96 Vcore reading... would a broken sensor do that?
EDIT 2: So the 0.96 reading is only in windows... In the UEFI I read 1.328v for vcore and 1.238v for cache.

Those pictures show a maximum frequency of 4Ghz, What is showing you 4.7?

I just tried redoing the settings, and got the same reading from Speedfan. The programs showing me 4.7 were CPU-Z, Task Manager, and Aida64. As a side note, the vcore thing in the screenshot is still 0.96, which is insanely low if the reading is true.
Also, when my system was in idle the frequency in Speedfan said 3997MHz while the task manager said something like 0.8 GHz.
