Dell-compatible DDR5 ECC RDIMM

This 128GB registered DDR5 module runs at 4800 MT/s with CL40 latency and 1.10V operation. It targets IT teams upgrading Dell servers or workstations that require ECC error correction and registered signalling for multi-module stability. The single-stick design simplifies capacity scaling in qualified platforms.

1x128GB kit simplifies slot population

The package contains one 128GB RDIMM, so administrators can fill empty slots without splitting kits or matching existing modules. Major OEM Samsung, Micron or Hynix chipsets are used, and every unit undergoes load stress testing before shipment to reduce early-life failures in mission-critical deployments.

288-pin registered form factor

The 288-pin DDR5 RDIMM keying prevents accidental insertion into unbuffered consumer slots, protecting both module and motherboard. Four-rank 4Rx4 organisation suits dense memory configurations, while the absence of a heat spreader keeps height low for restricted chassis airflow paths. Dell SNPMMWR9C/128G and AC449974 cross-references confirm mechanical and electrical fit.

Questions about this item

Will the 128 GB 4Rx4 module need any firmware updates or component swaps during its service life?

The DDR5 RDIMM has no user-serviceable parts and no firmware to update; it is installed once and runs for the system lifetime.

What throughput ceiling appears first when the 4800 MT/s registered DIMM runs sustained workloads?

The JEDEC DDR5 4800 interface caps sustained bandwidth at the rated PC5-38400 speed; the memory controller cannot exceed that transfer rate.

How much heat does the 1.1 V 288-pin RDIMM add when it runs continuously in a Dell server?

Operating at 1.1 V without a heat spreader, the module relies on chassis airflow; power draw stays within standard DDR5 RDIMM limits for this voltage.
