Samsung M321RYGA0BB0-CQK 96G DDR5 4800 RDIMM
The Samsung M321RYGA0BB0-CQK is a 96GB DDR5-4800 ECC registered DIMM (RDIMM) built for enterprise servers, cloud computing platforms, AI training clusters, and 24/7 data center operation. It suits buyers provisioning or expanding DDR5-generation server platforms — virtualization hosts, memory-hungry cache tiers, and AI/training workloads — where registered ECC memory is a platform requirement. Note that as a DDR5 RDIMM it is not backward-compatible with DDR4 sockets, and mixed population of different generations or module types is not supported.

Good to know
- Verify CPU and motherboard support for DDR5 RDIMM at 4800 MT/s before ordering — supported speeds and capacity per channel are platform dependent, and DDR5 RDIMMs will not work in DDR4 systems.
- Within Samsung’s DDR5 server lineup, this 96GB 2Rx4 module offers higher per-slot density than typical 32GB/64GB RDIMMs, letting high-density hosts reach large memory footprints with fewer populated slots.
- For mixed-capacity builds, confirm your server vendor’s memory population rules — matching rank configuration and speed across channels helps the platform run at its rated 4800 MT/s.
For tray and reel pricing, current stock by part number and date code, and volume discounts on bulk orders, request a bulk quotation.
