The DDR4 is labeled 1.35 volts on it and in bios list, but the voltage of the MSI board is 1.2 and set to Auto. Is this starving the memory?
Not my computer, just helping someone. The overall settings seem baseline, not overclocked at all.

Memory that is rated for over 2666 MHz will need to run at 1.35V.
You most likely didn't enable XMP... without the XMP enabled every DDR4 memory will run at either 2133 MHz or 2400 MHz depending on what kit you've bought. At 2133/2400/2666 MHz the memory will run at 1.2V... that's normal.

When you enable XMP and go over 2666 MHz you're basically overclocking your memory and it'll need more voltage, 1.35V being the standard spec... to reach the frequencies your memory manufacturer lists...

If their rated frequency is over 2666 MHz the XMP profile will automatically change the frequency, voltage to 1.35V and timings.

What memory kit do you have and what frequency is it rated at?
