SK Hynix demonstrated 48GB and 96GB DDR5-6400 registered memory modules for next-generation servers at Intel’s innovation event this week. The RDIMM uses the company’s latest he 24Gb DDR5 SDRAM device, combining high performance and high capacity.
SK Hynix showed off various memory modules for next generation servers including 32GB, 64GB, 128GB and 256GB DDR5-5600 RDIMM based on 16Gb DDR5 IC. 24Gb DDR5 IC, report serve the home.
Note that for now SK Hynix has only demonstrated 24Gb-based RDIMMs for servers, so you might not find them among the best RAM modules for gaming desktops. Still, nothing will stop SK Hynix from finally using the same 24Gb IC to produce a 24GB DDR5-6400 module for desktops.
While some might consider 24Gb, 48GB, and 96GB capacities to be “non-standard” or “non-binary,” they actually offer three key advantages. Cloud Service Providers (CSPs) can more precisely match the amount of DRAM to a specific capacity per core. 24Gb DDR5 ICs can be manufactured with good yields using today’s most advanced process technology. These memory devices can support data transfer rates of 6400 MT/s without compromising yield.

While “more is better” is our typical approach to PC memory capacity, CSPs want to allocate a very specific amount of memory (and hopefully memory bandwidth) per core. increase. For example, if a CSP needs his 6GB of RAM per core on AMD’s EPYC 7763, ideally per socket he should install 384GB of memory. The problem is CSP can’t do this with his 32GB or 64GB modules in an 8 channel memory subsystem. Things get more complicated when AMD releases 96-core and 128-core EPYC CPUs with 12-channel memory subsystems and Intel launches 60-core Xeon Scalable ‘Sapphire Rapids’ processors. This is when 48GB and 96GB modules come out to simplify life for CSPs.
As for SK Hynix’s 24Gb (3GB) DDR5 memory device itself, it is manufactured in a 1anm manufacturing technology that uses both extreme ultraviolet (EUV) and deep ultraviolet (DUV) lithography to increase device density without sacrificing yield. Remember that The adoption of EUV lithography has enabled SK Hynix to increase the capacity of DRAM ICs to 24Gb, improve the performance of memory devices to 6400 MT/s, and improve production efficiency. SK Hynix’s 48GB DDR5-6400 RDIMM uses twenty 24Gb devices, while the 96GB DDR5-6400 registered module relies on 40 such ICs.
Both Samsung and SK Hynix have been sampling 24Gb-based RDIMMs with various parties for just under a year, so 24GB, 48GB, and 96GB DDR5 memory modules will be available around the time of AMD’s and Intel’s next-generation server platforms. expected to be. hit the market.
