I've read about the VRVout else where but once more lol my board doesn't have it lol. I've tried so find it, not voltage date at least on HWinfo64 with that name, where's yours?
I'm going to try leaving the LLC on auto which i think it uses 4 and see what i get. Im using Linx64 so it uses AVX(Realbench does as well), i know that when AVX hits ,my vcore shoots up a bit. I may try also an AVX offset to try an keep the vcore from jumping compared to non AVX state.
Just because CPU speed stays constant does not mean that load is constant or that the vcore should be constant when in offset mode.
Watch the values of VID for each core. That's the processor telling your motherboard how much voltage it wants. Those are not constant when I watch them during a stress test.
As those vary, the processor is telling the motherboard to vary the voltage it gives the CPU. Perhaps this varying VID is more pronounced in this generation than what you've previously overclocked with?
In the end, what you should care about is system stability, not how constant the VCORE voltage is. In fact, you want the motherboard to lower the voltage the moment it can (even if just a little bit and even while still at full speed) because that creates less heat and makes for lower temperatures.
I can't tell you exactly where VRVout was for me because I've rearranged the rows since in HWiNFO64. I think it was about 2/3 of the way down when scrolling. But, it is present only in some boards.
