Need help with deciphering OCCT graphs.

[Evo73]

I recently did a tear down and rebuild to upgrade my cooling system. I always run OCCT afterwards to to verify everything is running as it should. While running the tests I noticed some weird readings. To my eye, it looks like my VRMS may be having issues. But, I would like to hear what others think.

6 are runs at 4.0ghz/3200. And one at default settings.

Thoughts??
