No ratification of DDR4 3200Mhz?

[Elixer]

Was poking around on the JEDEC site, and I only see DDR5 on their roadmap, nothing about ratifying anything higher than DDR4 2667MHz.

Obviously, there are DDR4 DIMMs out there that say they support 3200MHz (or higher), so, one has to wonder, how are they arriving at the specs?
We got multiple vendors, and some are using different chips, so, without any input from JEDEC it is no wonder than it is more difficult to support all the different 3200MHz RAM out there.

ETA for DDR5 is 2020.

I would have just assumed that JEDEC would be on top of this by now.

ALL DDR4-3200 DIMMs are overclocked RAM. There is no DDR4 DRAM producer (that I know of) producing DDR4-3200 -rated chips.

That's why they need XMP.

Right, but, as I said, you would think that they would have ratified a 3200MHz by now, instead of everything being overclocked.

Didn't it take years and years for DDR3 to go from 1066 to 1333 to 1600? And 1866 and above were never touched by JEDEC. As a standards body, I don't think they generally bother attempting to push performance boundaries, as the closer you are to the bleeding edge, the harder it is to achieve consistent performance. I'd say it's pretty good that we have officially supported non-OC 2667 DDR4 by now.

Edit: Not to mention that standardization of DDR4-3200 would necessitate a base spec for controllers capable of that speed, which if Ryzen is anything to go by is easier said than done.

Most of the ddr4 3000 and up are running above 1.2v usually around 1.35v. That puts them out of spec. So we will probably not see jedec ddr 3000+.
