XMP Voltage?

Hi, I've just got an MSI Pro B660M-A WiFi DDR4 with an i5-12600 and 32GB DDR4-3200mhz and when turning on XMP, when the profile is 1.35V, the board seems to run the RAM at (varies between) 1.364-1.368V? Is that normal? Or is it because DDR4 is so finnicky on Alder Lake MSI has the board run the RAM faster than the profile says?

(on a side note, I previously had a B660M Mortar that I had to return that ran the RAM at only 1.360V....still higher than XMP but not as high as this board)

Thanks

This is completely normal, the RAM VRM (voltage regulator module, converting 12V from the PSU into the 1.xxV for the RAM) is usually a couple Millivolts off, also on boards of other brands.
Usually it will apply a bit more. Nothing to worry, as the voltage sensors/readouts are usually off by a bit too! So if you were to measure with a calibrated multimeter, you'd probably be on target again.

The only time where you would worry is when this voltage fluctuates under RAM load. But it should usually be rock stable.
