SK Hynix demonstrated its upcoming 48GB and 96GB DDR5-6400 registered reminiscence modules for next-generation servers at Intel’s Innovation occasion this week. The RDIMMs use the corporate’s newest 24Gb DDR5 SDRAM units and produce collectively excessive efficiency and excessive capability.
SK Hynix confirmed off a wide range of reminiscence modules for next-generation servers, together with 32GB, 64GB, 128GB, and 256GB DDR5-5600 RDIMMs based mostly on 16Gb DDR5 ICs in addition to 48GB, and 96GB DDR5-6400 and DDR5-5600 RDIMMs that includes its 24Gb DDR5 ICs, stories Serve The House.
It is value noting that, for now, SK Hynix has solely demonstrated 24Gb-based RDIMMs for servers, so chances are you’ll not be capable of discover them amongst our greatest RAM modules for gaming desktops. But, nothing is stopping SK Hynix from making 24GB DDR5-6400 modules for desktops utilizing the identical 24Gb ICs ultimately.
Whereas some might take into account 24Gb, 48GB, and 96GB capacities ‘nonstandard’ or ‘non-binary,’ they really have three vital benefits: they permit cloud service suppliers (CSP) to extra precisely match the quantity of DRAM to a particular capability per core; 24Gb DDR5 ICs might be produced with adequate yields utilizing at the moment’s modern course of applied sciences; and these reminiscence units can help a 6400 MT/s knowledge switch charge with out hurting yields.

“The extra the merrier” is our typical strategy to reminiscence capability of our PCs, however CSPs wish to assign a really particular reminiscence capability (and ideally reminiscence bandwidth) per core. For instance, if a CSP needs 6GB of RAM per each core of AMD’s EPYC 7763, it should ideally want to put in 384GB of reminiscence per socket. The issue is, the CSP can’t do that utilizing 32GB or 64GB modules inside an eight-channel reminiscence subsystem. The scenario goes to get trickier as soon as AMD releases its 96-core and 128-core EPYC CPUs with a 12-channel reminiscence subsystem and Intel launches its 60-core Xeon Scalable ‘Sapphire Rapids’ processors. That is when 48GB and 96GB modules come into play to simplify lives of CSPs.
Talking of SK Hynix’s 24Gb (3GB) DDR5 reminiscence units themselves, do not forget that they’re made on 1anm fabrication expertise that makes use of each excessive ultraviolet (EUV) and deep ultraviolet (DUV) lithography to extend gadget density with out sacrificing yields. Adoption of EUV lithography allowed SK Hynix to extend capability of its DRAM ICs to 24Gb, efficiency of reminiscence units all the way in which to 6400 MT/s in addition to enhance manufacturing effectivity. SK Hynix’s 48GB DDR5-6400 RDIMM makes use of 20 24Gb units, whereas the 96GB DDR5-6400 registered module depends on 40 of such ICs.
Each Samsung and SK Hynix have been sampling their 24Gb-based RDIMMs with numerous events for rather less than a 12 months now, so count on availability of 24GB, 48GB, and 96GB DDR5 reminiscence modules across the time next-generation server platforms from AMD and Intel hit the market.
