G.Skill RipJaws 4 DDR4 Memory Modules Pictured

My 1600mhz memory ran by default at 1333mhz on my AMD system because it doesn't support XMP. It's spec'ed to 1600mhz at stock voltage. That's not overclocked. Not sure what you're talking about.

1333/1600/2133 MHz is default for DDR4. Not sure what YOU are talking about. Anything that is not a JEDEC profile needs XMP, since JEDEC also specifies timings and voltages. Anything that is outside the JEDEC spec requires an XMP profile for easy settings. Just how it has been with Intel for years. XMP is NOT a new standard.
