Adaptive voltage higher than manual

[benjii]

I've finished fine tuning the OC on my 6700k (mobo is Maximus VIII Hero Alpha) and it's rock solid; overnight tests of RealBench and x264 stability as well as a few days of usual use. It's at 4.7Ghz @ 1.344v under load, LLC 6 (1.32v in bios). All of this testing was obviously done using manual voltage. I switched to Adaptive, set 1.32 turbo and the offset at 0.001. The problem is, my vcore now hits 1.376 and that was just a spike on desktop. I've tried leaving the offset on auto as well as setting it as minus 0.001, that had the same results.

I'm not sure what I can try or what is causing this. As an aside, I can't drop LLC to 5 or else I get vdroop. I'd welcome any help or suggestions.

I think it's because that's what happens when you do a synthetic stress test with adaptive voltage.

If you don't care about power efficiency and idle temps (like me) then you could leave it on manual since you have a solid OC already ..

That used to be an issue, but that was resolved with Skylake and is no longer a problem. Also, the spikes occurred on desktop not during stress testing. Stress testing volts were actually a little lower, 1.36v.
