Speed DDR4 2133 (PC4 17000)

  • 256 GB total capacity across eight 32 GB modules
  • DDR4 2133 MHz speed with CL15 latency for responsive operation
  • ECC registered design detects and corrects data errors
  • 2 V operation reduces power draw per module
  • Validated for Dell PowerEdge 13th Gen rack servers R430 through R930

Server Memory Upgrade

This 256GB kit contains eight 32GB DDR4 2133MHz ECC registered DIMMs built for Dell PowerEdge 13th generation rack servers including the R430, R530, R630, R730, R730xd, R830 and R930 models. It targets administrators who need maximum capacity across all memory channels for virtualisation, database or high-throughput workloads. Each module operates at 1.20V with CL15 latency and a 2Rx4 organisation.

Capacity Expansion Path

The kit replaces smaller factory configurations or mixed-capacity DIMM sets that limit total addressable memory and channel balance. Installing eight identical 32GB modules ensures the system runs at the full 2133MHz rated speed without down-clocking to the slowest installed stick. It is not suited for desktops, laptops or any platform that only accepts non-ECC unbuffered memory.

Sustained Operation Profile

Registered buffering and on-die ECC maintain data integrity during continuous multi-threaded processing across all populated channels. The dual-rank x4 layout allows the memory controller to interleave requests efficiently, keeping throughput stable during extended compute cycles. Modules lack heat spreaders, so adequate chassis airflow is required to maintain specified operating temperatures under full load.

Questions about this item

What Dell PowerEdge servers accept this 288-pin DDR4 RDIMM kit?

This kit is designed for Dell PowerEdge R430, R530, R630, R630 XL, R730, R730 XL, R730xd, R730xd XL, R830 and R930 13th Gen rack servers.

Which memory slots should I populate first when installing these eight 32GB 2Rx4 modules?

Follow the server manual for the correct channel population order; the most common mistake is filling slots sequentially instead of balancing across memory channels.

When should I replace a module if ECC starts logging corrected errors?

Replace a module when the system management log shows a rising corrected-error count on a specific DIMM, indicating that the 2Rx4 chipset is degrading.
