Samsung M321RAGA0B20-CWK 128GB DDR5 4800 ECC 3DS RDIMM

SKU CH-C3SD-EA1XN

High-capacity 128 GB DDR5 server RDIMM with ECC and 3DS stacking at 4800 MT/s

  • 128 GB capacity supports dense virtualization workloads
  • DDR5 4800 MT/s delivers high memory bandwidth
  • ECC protection corrects single-bit errors automatically
  • 3DS stacking enables 128 GB in a single module
  • RDIMM registration reduces electrical load on the memory bus

Server DDR5 RDIMM

This Samsung DDR5 RDIMM delivers 128 GB of registered ECC memory for enterprise servers and workstations. The 3DS stacking enables high density in a single module slot. It targets IT professionals who need maximum capacity per channel for virtualization, databases or in-memory analytics.

Registered ECC 3DS architecture

The registered buffer reduces electrical load on the memory controller, allowing larger populations per channel. On-die ECC corrects single-bit errors internally while the module ECC protects data across the bus. The 3DS package stacks multiple dies to reach 128 GB without occupying additional DIMM slots.

128 GB at 4800 MT/s

At 4800 MT/s the module supplies high bandwidth for memory-bound workloads such as large VM fleets or scientific datasets. Capacity runs out when applications exceed the physical address space of the platform or when latency-sensitive tasks demand lower timings than the standard JEDEC profile provides.

商品問答

What sustained-load limit does the 128 GB DDR5 4800 module hit first?

The 4800 MT/s data rate is the ceiling; under continuous load the memory cannot exceed this transfer speed.

How much heat or noise does the 128 GB DDR5 4800 RDIMM produce during all-day operation?

The module has no moving parts and runs silently; thermal output is typical for a registered DDR5 DIMM at 4800 MT/s.

Which motherboard slot and chipset must I already have for this 128 GB DDR5 4800 ECC RDIMM to work?

A server-class board with DDR5 RDIMM slots that support ECC and 3DS stacking is required.
