32GB DDR5 4800 ECC Registered RDIMM

This 32GB DDR5 module operates at 4800 MT/s with CL40 latency and 1.10V voltage. It uses Micron chips in a 2Rx8 registered layout with on-die ECC. The stick is built for servers and workstations that require registered memory with error correction.

Capacity and headroom

A single 32GB RDIMM suits virtualisation hosts, database nodes and compute clusters that need registered ECC memory. Two-rank density helps populate high-slot-count boards without exceeding rank limits per channel. Workloads demanding more than 32GB per slot will require additional modules or higher-capacity RDIMMs.

DDR5 4800 interface limits

The DDR5 4800 (PC5 38400) interface caps peak bandwidth at the JEDEC base rate. Registered buffering adds a cycle of command delay, which is normal for server platforms. Systems that only support lower DDR5 speeds or unbuffered DIMMs cannot use this module.

Highlights

  • 32 GB capacity supports large server workloads
  • DDR5 4800 speed delivers high data throughput
  • ECC registered design corrects memory errors
  • CL40 CAS latency provides responsive access timing
  • 10 V operation reduces power consumption

Questions about this item

Will this 32GB DDR5 4800 RDIMM work in a system that already has DDR5 modules installed?

It will operate at the lowest common speed and voltage of the installed modules; mixing ranks or latencies such as CL40 with different timings may limit stability.

How can I verify the module is running at 4800 MT/s with ECC active after installation?

Check the BIOS memory information or an OS tool such as dmidecode; both should report 4800 MT/s, 1.10V, registered operation and ECC enabled.

Does the package include only the 32GB RDIMM or are any cables or brackets supplied?

Only the MEM-DR532L-CL01-ER48 module is included; no cables, brackets or additional hardware are provided.
