Some solutions for anyone looking:
XMP: Literally, and this is not a joke, if your RAM is in slots 1 and 3, move it to slots 2 and 4, it will work fine at its rated speed there. (3000 worked like a charm for me after this fix)
RGB: https://github.com/ixjf/MSIRGB (Yeah, MSI was just lazy...)
Fan speed: Just manually set it!
