Your ram is : DDR4-3200 MHz which is the rated speed for them.
Your System is Auto Lowering them to 2133 to be compatible to the max ram speed of the Chip.
(this may explain why the Voltage was set down to 1.2v) You can get them manually to run @3200 but.....
EDIT : it is the pitfall that happens when not research the ram speed for the chip. Happens to everyone (including me).
