Anyone else's DIMM voltage being very inconsistent? It's been like this on my original board and the RMA'd board. I haven't tested every increment, obviously, but for example:
 
I set 1.375 and it gets set to 1.408 at restart. Anything between 1.45-1.474 it gets set to 1.485. Once I hit 1.475 it goes to 1.511. Is this tied to something else and that's why it's getting affected? Thoughts?
 
Makes fine tuning my RAM pretty rough.

For this issue please contact EVGA technical support. 

I would guess that the voltage is adjusting in smaller increments closer to what you selected, but what is displayed to you is too coarse to be extremely accurate. A multimeter would confirm one way or another. I mean, we are talking only 30 millivolts here. I don't know that tuning memory voltage within 30 millivolts is super important.

My Z490 FTW & Z590 FTW does the exact same thing, I would say it's normal operation and nothing to worry about

I just found it odd that it jumped so high from 1.475. And by high I mean relatively speaking.
