Is XMP common across all or most DDR4 DIMMs?

[thekingofmonks]

I've never played with DDR4 gen desktop hardware and have never owned any.

Is XMP a common thing with DIMMs of rather high speeds such as 3200MT/s, even from cheap brands? Or do I need to be particularly selective just like when purchasing other gens?

Xmp or Docp is standard on even super budget ddr4, and even necessary to achieve the advertised speeds. So yes, the kit you buy should have it, and yes, you should probably turn it on.

XMP is pretty standard on all consumer RAM, I haven't mucked with ECC stuff so IDK there. Any kit will run at the basic JEDEC spec or around there (different motherboards will decide on different speeds) if you just don't enable the XMP profile in the BIOS.

JEDEC specification stops at 3200 MHz. XMP is required to define operating parameters at faster speeds.

 The XMP is present in 90%+ of the DDR4.

As stated before - JEDEC is "maxed out" at 3200MT/s
