SK Hynix Shows Off Odd-sized 48GB and 96GB DDR5 RDIMMs at InnovatiON

SK Hynix at the 2022 Intel InnovatiON event, showed off some unconventional server memory capacities. The company presented DDR5 RDIMMs in 48 GB and 96 GB densities, besides the usual 32 GB, 64 GB, and 128 GB ones. These are being offered in data-rates of DDR5-5600 and DDR5-6400, which indicates that DDR5-5600 (JEDEC-standard) could be the standard memory speed supported by Xeon Scalable "Sapphire Rapids" processors, with some (or all) models also supporting DDR5-6400. These are not XMP or overclocking SPDs, but JEDEC-standard ones that the processors can automatically train to. The flagship product among SK Hynix's booth would have to be a mammoth 256 GB DDR5-5600 RDIMM, which should enable servers with up to 4 TB of memory per socket (@2 RDIMMs per channel).

I don't think these sizes are odd. Kinda surprised it hasn't happened yet. It would be cool if they did 12GB x 2 & 24GB x 2 kits.

Well, hopefully this will get filtered down to the consumer space in a few generations from now, which I'm sure will require some major reworking of the memory slots & controllers, but since team bluehoo is involved, it will be insanely expensive, as they are always looking for yet ANUTHA revenue stream that can be used to milk us out of moar & moar of our hard earned cash...

Epyc Genoa is 12 channel, correct? Does that mean that the supporting motherboards will have 24 DIMM slots? and thus theoretically support 6,144GB of memory per socket with 256GB dimms? Meaning over 12TB of memory on a two socket board?

Sounds about right.

With meager 256GB DIMMs, yes, 12TB, but Samsung has announced 768GB DIMMs :)

Hmm but why? What's the advantage of odd sizes, making quick math slightly harder? :D

Maybe it's a question of why not, still seems weird

lexluthermiesterAnd variety.
Well sort of the same thing in this context. More user choice.

Agreed, but this generation!
