Server-grade ECC memory

This 16GB DDR3L registered DIMM adds error-correcting capacity to compatible HP ProLiant servers. It operates at 1600MHz with CL11 latency and a low 1.35V voltage. The module uses a 2Rx4 organisation and a 240-pin form factor. It is designed for workloads that require data integrity and registered buffering.

Thermals and power draw

The DDR3L voltage of 1.35V reduces power consumption compared with standard DDR3 modules. No heat spreader is fitted, so airflow across the PCB handles thermal dissipation. Registered buffering adds minimal electrical load to the memory controller. Typical server chassis airflow keeps temperatures within JEDEC limits during normal operation.

Sustained load behaviour

ECC registered architecture maintains signal integrity across all ranks during continuous read and write cycles. The single 16GB rank configuration avoids interleaving delays under heavy multi-threaded workloads. CL11 timing remains stable without voltage scaling. The module replaces HP part numbers 684316181, 688963001, 713756081, 713985B21, 713985B211 and 715284001 for validated compatibility.

Questions about this item

How do I install this 240-pin DDR3L ECC RDIMM in an HP ProLiant SL250s Gen8, and what step is often missed?

Power down the server, open the chassis, align the notch on the 240-pin module with the slot key, press firmly until both retention clips click, then verify in BIOS that the 16GB module is detected at 1600 MHz with ECC active.

What maintenance or replacement will this 16GB registered DIMM need over time?

No routine maintenance is required; if a memory error appears, run the server diagnostics to isolate the faulty DIMM and replace the single 16GB module rather than the full set.

What limit appears first when this CL11 1.35V module runs under sustained load?

The DDR3L 1600 CL11 timing and 1.35 V voltage set the maximum stable throughput; sustained heavy workloads will hit this bandwidth ceiling before thermal throttling becomes a factor.
