Capacity and fit

This 768GB kit contains twelve 64GB DDR4 LRDIMM modules built for Dell PowerEdge 13th generation rack servers including the R430, R530, R630, R730, R730xd, R830 and R930 families. It targets administrators who need maximum registered ECC capacity in those specific platforms. The modules use a 288-pin form factor with a 4Rx4 quad-rank layout and will not work in desktop or laptop systems that require non-ECC unbuffered memory. Mixing with standard registered DIMMs is not supported.

Thermals and power at 1.20V

Each module runs at 1.20V without a heat spreader, relying on the server's directed airflow for cooling. Load-reduced buffering reduces electrical load on the memory bus, helping keep power draw predictable during normal operation. The CL15 latency at 2133MHz delivers standard timing for this voltage class. No additional cooling hardware is included or required beyond the chassis design.

Sustained load behaviour

Under continuous workloads the quad-rank organisation allows the memory controller to interleave across ranks, maintaining throughput when all twelve slots are populated. Speeds are locked to the slowest installed module, so the kit will run at 2133MHz even if faster modules are present elsewhere. ECC correction operates continuously to protect data integrity during extended compute tasks.

Questions about this item

How do I install the 12 DDR4 2133 LRDIMM modules in a Dell PowerEdge R730, and which seating step is often missed?

Power down the server, open the chassis, and insert each 288‑pin module into the slots specified by the R730 memory‑channel guide; the step most often missed is following the exact channel population order for 4Rx4 LRDIMMs so the system recognises all 768GB.

What maintenance or replacement will the 12‑module 768GB LRDIMM kit need over its service life?

No scheduled maintenance is required; keep the server’s air filters clean so the modules stay within their 1.20V operating envelope, and replace any individual 64GB stick only if diagnostics report a correctable ECC error that becomes uncorrectable.

What limit appears first when the 4Rx4 DDR4 2133 LRDIMMs run under sustained load in a 13th Gen PowerEdge?

The memory controller caps throughput at the DDR4 2133 MT/s rating (PC4‑17000), so sustained bandwidth tops out at that speed regardless of workload intensity.
