16GB DDR3L 1600 ECC registered DIMM running at 1.35V for server upgrades
This 16GB registered DIMM is built for servers and workstations that require error-correcting memory. It operates at 1600MHz with a low 1.35V voltage profile. The module replaces specific Micron part numbers including MT36KSF2G72PZ-1G6E1FI and related variants. It suits administrators expanding capacity in compatible 240-pin DDR3L slots.
A single 16GB module adds substantial memory headroom for virtualisation, database caching and multi-user workloads. The 2Rx4 organisation and CL11 latency support steady throughput under sustained loads. Systems limited to lower-density slots or non-ECC architectures cannot use this module. Maximum capacity depends on the motherboard's supported DIMM count and rank limits.
The registered buffer and ECC functionality are the decisive specifications for platform compatibility. This module uses Micron chipset components and requires a motherboard that supports registered ECC DDR3L DIMMs. It will not function in desktop boards that accept only unbuffered non-ECC memory. Verify the system's qualified vendor list before installation.

The module operates at DDR3L 1600 (PC3L-12800) with CL11 latency and 1.35 V. Mixing it with other DDR3 1600 registered DIMMs of the same voltage and timing will generally work, but the system will run all modules at the speed of the slowest one.
Enter the server BIOS or UEFI and confirm the total capacity shows the expected 16 GB per module, the speed reads 1600 MHz, and ECC is reported as enabled or active.
The package contains the single 16 GB 2Rx4 registered DIMM. No additional cables, brackets or software are required; only a compatible 240-pin DDR3 RDIMM slot on the motherboard is needed.
