8 GB DDR4 2133 ECC Registered Server Module

This 8 GB DDR4 module runs at 2133 MHz and carries ECC and registered signal processing for server workloads. It fits 288-pin DIMM slots and is validated for Dell PowerEdge R630, R730, R730xd and T630 systems.

Registered Buffer and ECC Limits

The registered buffer adds one clock cycle of latency and the ECC logic consumes extra bits, so the module trades raw speed for data integrity and electrical load reduction on the memory bus.

8 GB Capacity Headroom

Eight gigabytes supports typical virtualisation hosts and database nodes with moderate memory pressure. Workloads that scale beyond this per-slot capacity will require additional modules or higher-density DIMMs.

Questions about this item

Should I choose the 8GB module or look for a different capacity for my server?

This listing is for a single 8GB DDR4 2133 ECC Registered DIMM. Select it if you need to add one 8GB stick or build a configuration in 8GB increments.

What does the 2133 MHz speed deliver when installed in a compatible Dell PowerEdge server?

The module runs at DDR4 2133 (PC4 17000) providing ECC error correction and registered signal processing for stable operation in supported R630, R730, R730xd and T630 systems.

How does the 288-pin DDR4 interface and registered design affect what the memory can do?

The 288-pin DDR4 form factor fits DDR4 server slots only. Registered buffering reduces electrical load on the memory controller, allowing larger total capacities in supported Dell PowerEdge platforms.
