16GB DDR3L-1600 ECC Registered DIMM

This 16GB DDR3L module runs at 1600 MHz with a CAS latency of CL11. It is built with Hynix dual-rank x4 chips and operates at 1.35V. The registered design adds a buffer to reduce electrical load on the memory controller.

Servers needing registered DDR3L memory

This module suits systems that require 240-pin DDR3L ECC registered DIMMs at PC3-12800 speed. It is not for desktop boards that accept only unbuffered non-ECC memory. It is also not for platforms limited to DDR3L single-rank configurations.

240-pin DDR3L registered form factor

The 240-pin registered DDR3L interface determines whether this DIMM fits the target server. Verify that the platform supports registered ECC modules at 1.35V before purchase.

Questions about this item

Will the 1.35 V DDR3L voltage limit headroom when the module runs continuously at 1600 MT/s?

The module is specified at 1.35 V for DDR3L-1600 operation, so sustained full-speed use stays within the rated voltage envelope.

How much heat does the registered 16 GB dual-rank stick produce inside a crowded 240-pin server chassis?

Registered DDR3L at 1.35 V typically runs cooler than standard 1.5 V DDR3, reducing thermal load in dense 240-pin configurations.

Does my motherboard need to support ECC and registered DDR3L to use this 16 GB CL11 module?

Yes — the board must accept DDR3L registered ECC memory at 1600 MT/s with CL11 timing for the module to function correctly.
