I've been trying to overclock my processor (Phenom II 1100T) recently and decided to run CPU-Z to get a confirmation of where I was at. I noticed that the Core Voltage displayed in CPU-Z and VCore in the PC Health Status section of the BIOS is different than what was set in the BIOS. In the BIOS, I set it to be 1.375. CPU-Z displays it as either 1.424 or 1.440. It jumps between the two frequently. Under load, it goes to a concerning 1.472V. I'm guessing that some minor fluctuation is normal, but why is there such a high difference between what I've set it to and what CPU-Z/PC Health Status says and how can I fix this, if it is even fixable? I'm just concerned now about the actual voltage and how much headroom I really have left here. I've tried looking this up, and haven't found a solution for it. Is there a setting maybe that causes this discrepancy?
Extra information in case it can help:
In the BIOS, I've turned off AMD's Cool and Quiet, C1E, manually set all of the RAM information, upped the clock speed of the CPU, disabled the turbo boost things, and upped the voltage for the CPU by .025 (to the 1.375 that it should be at now). Current clock speed is approximately 4027 MHz (as reported by CPU-Z, set as 4000 in the BIOS, but I'm certain that this isn't an issue)
Motherboard: Gigabyte GA-970A-UD3
Processor: AMD Phenom II x6 1100T
RAM: Corsair Vengeance 8GB (2x4GB) (9-9-9-9-24, 1600)
I also went ahead and did some testing with differences between what I set and what I get:
When I set it to 1.350V (the default), according to the BIOS VCore, I'm actually at 1.376V. Likewise, 1.375V nets me 1.424V, and 1.400V apparently gets me 1.440V.
