High-Capacity DDR3 Server Module

This 32GB DDR3 1866MHz ECC LRDIMM is built for servers and workstations that need large memory footprints in a single 240-pin slot. It targets administrators upgrading compatible Dell platforms such as part numbers 370-ABGL, A7187321, A7545684 and SNPJGGRTC/32G where registered load-reduced memory is required.

32GB Rank Density and Headroom

The 4Rx4 organisation delivers 32GB per module, letting a supported board reach high total capacity with fewer populated slots. CL13 latency at 1866MHz provides steady throughput for virtualisation and database workloads, while the load-reduced buffer eases electrical loading on the memory controller. Systems limited to lower-rank DIMMs or non-ECC memory cannot use this module.

Standard Voltage Thermals and Power

Operating at the standard 1.50V DDR3 voltage, the module draws typical power for its class without needing extra cooling beyond normal server airflow. The major-brand chipset and rigorous testing ensure stable temperatures under sustained load, and the load-reduced design helps keep signal integrity clean in dense configurations. No additional voltage headroom is required.

Questions about this item

Will this 1866MHz PC3-14900 LRDIMM run at its rated speed alongside slower DDR3 modules already installed?

The module is specified at DDR3 1866MHz PC3-14900 CL13 1.50V. When mixed with slower DDR3 DIMMs the system will typically clock all modules down to the lowest common speed and tightest timings.

How can I verify this 4Rx4 ECC LRDIMM is recognised and operating correctly after installation?

Check the system BIOS or UEFI memory information screen; it should show a single 32GB DDR3 1866MHz ECC Load Reduced DIMM with 4Rx4 organisation.

Does the 240-pin DDR3 LRDIMM ship alone or with any accessories such as a heatsink or installation tool?

The package contains one 32GB 240-pin DDR3 1866MHz ECC LRDIMM module only; no heatsink, tool or extra cables are included.
