DDR5 Memory Specification Released: Setting the Stage for DDR5-6400 And Beyond

[axipher]

Marking an important milestone in computer memory development, today the JEDEC Solid State Technology Association is releasing the final specification for its next mainstream memory standard, DDR5 SDRAM. The latest iteration of the DDR standard that has been driving PCs, servers, and everything in-between since the late 90s, DDR5 once again extends the capabilities of DDR memory, doubling the peak memory speeds while greatly increasing memory sizes as well. Hardware based on the new standard is expected in 2021, with adoption starting at the server level before trickling down to client PCs and other devices later on.

 

Originally planned for release in 2018, today’s release of the DDR5 specification puts things a bit behind JEDEC’s original schedule, but it doesn’t diminish the importance of the new memory specification. Like every iteration of DDR before it, the primary focus for DDR5 is once again on improving memory density as well as speeds. JEDEC is looking to double both, with maximum memory speeds set to reach at least 6.4Gbps while the capacity for a single, packed-to-the-rafters LRDIMM will eventually be able to reach 2TB. All the while, there are several smaller changes to either support these goals or to simplify certain aspects of the ecosystem, such as on-DIMM voltage regulators as well as on-die ECC.

Mmmmm nice, one day lol when my next upgrade happens.

 

I have not looked at the full specifications but I assume the on die ECC will be on server ram only and not typical consumer RAM. Would be nice if it becomes a standard across the board one day.

Zen 4 and 5 should bring the support with AM5 socket, but that atm is still on question mark as if AM5 doesn't bring DDR5 that would be the first time socket doesn't match it's naming scheme, as AMD names their AM sockets with RAM generation in the name.

[ENTERPRISE]

Would be nice if they didn't change the socket for obvious reasons but it is likely that they will for naming convention and possibly technical reasons.

I mean worst case scenario they will use a FM socket

Why an FM socket out of interest ?

Pretty sure AM5 would be DDR5 to match all their previous launches.

 

Not sure how different DDR4 and DDR5 will be in terms of memory controllers, but they could do the AM4+ / AM5 approach, but I think it would be nice to have proper walls.

 

 

With AMD's new income stream and more stable income, I can see them moving to a AM5 socket for DDR5 compatibility, while having AM4 options of the new processor architectures as well as long as.

 

Naming would be something that they need to figure out for sure to keep all confusion out. It would actually be nice to have the Socket Generation part of the CPU names would be nice, so if 4000 becomes the last generation that AM4 sees

FM sockets are kinda hybrid sockets something they have used between generations in the past.

I very much remember the FM sockets, but only that they superseded a prior socket I was using way back in the day. Will have to look up what is hybrid about them.

Wasn't the FM socket updated since AM3 didn't support APU's and AMD needed to get a foot hold in that market?
