How do I enable XMP and verify my RAM is reading 32GB?

Check that BIOS reports 32GB total, then turn on XMP (or DOCP for AMD) to get the rated speed. If it shows less, you probably didn’t seat one stick all the way or you’re in the wrong slots — most boards want slots 2 and 4 (counting from CPU) for dual channel. Speed defaults to a safe 2133 or 2400 MHz until you enable XMP in the “Overclocking” or “AI Tweaker” section — one toggle, save, reboot.
