32Gbit density planar (non-stacked) DDR5 DRAM production began in the second half of 2024 from the world’s leading DRAM semiconductors, enabling new, high-capacity DDR5 modules for client and server-class systems. Using advanced next-generation lithography, 32Gbit DRAM packs more memory cells into the same physical package size as 16Gbit and 24Gbit DDR5 chips. More cells per chip mean more capacity for existing memory module form factors, such as DIMMs and SODIMMs, allowing systems to achieve higher total capacities not seen before without using costly stacked DRAM (3D TSV / DDP) technologies.
UDIMM / SODIMM with 32Gbit DRAM
4x (2G x16) DRAM = 16GB in 1 rank
8x (4G x8) DRAM = 32GB in 1 rank
16x (4G x8) DRAM = 64GB in 2 ranks
Traditional desktop systems with a four-socket dual channel memory architecture can achieve up to 256GB with 64GBUDIMMs/CUDIMMs, while laptops and small-form-factor systems using the SODIMM/CSODIMM form factor can achieve a total 128GB of system RAM in two sockets.
Servers and workstations primarily benefit from the cost savings and unrestricted availability of 128GB-capacity Registered DIMMs (RDIMMs) using 32Gbit DRAM, since this and higher-capacity DDR5 RDIMMs were previously restricted to using 3DS stacked DRAM components.

Kingston was the first memory module manufacturer to build 64GB UDIMMs featuring 32Gbit DRAM for demonstration at CES 2024, and worked closely with major motherboard manufacturers (ASRock, Gigabyte, MSI) in late 2023 to enable them to achieve 256GB total memory capacity on their systems.
