32GB DDR3 1866 ECC LRDIMM Server Memory

This A-Tech module delivers 32GB of DDR3 1866 (PC3-14900) capacity in a single 240-pin DIMM. It operates at standard 1.5V voltage with CL13 latency and uses major brand chips. The load-reduced design reduces electrical load on the server memory bus for stable operation in dense configurations.

ECC Load-Reduced DIMM with 4Rx4 Organisation

The critical specification is the ECC LRDIMM 4Rx4 architecture, which combines error correction with load reduction for high-density server platforms. This module replaces Samsung M386B4G70BM0-CMA and M386B4G70DM0-CMA part numbers. Systems must explicitly support DDR3 LRDIMM technology and 4Rx4 rank configuration for correct operation.

For servers needing maximum DDR3 density per slot

This suits administrators upgrading compatible DDR3 platforms that require 32GB LRDIMM modules for virtualisation or database workloads. Builders using standard RDIMM-only motherboards, consumer desktop boards, or systems limited to lower densities should look elsewhere. Verify your platform's qualified vendor list before purchasing.

Questions about this item

What does the DDR3 1866 MHz speed mean once the module is installed in a server?

The module operates at 1866 MHz with CL13 latency at 1.5V, providing the rated DDR3 1866 data rate when the platform runs memory at that speed.

How does the PC3-14900 designation relate to the memory interface?

PC3-14900 is the DDR3 1866 standard name; the module uses a 240-pin DIMM interface and will run at the highest speed the system's memory controller allows.

What physical slot and clearance does this 32 GB LRDIMM require?

It fits a standard 240-pin DDR3 DIMM socket; the load-reduced design does not change the keying or height compared with a regular registered DIMM.
