Capacity 16GB

  • ECC registered design protects data integrity in servers
  • 16GB capacity at 1600MHz CL11 boosts multitasking throughput
  • Low 1.35V DDR3L operation reduces power draw
  • 240-pin RDIMM fits Supermicro X9 series motherboards
  • Single 2Rx4 module simplifies capacity expansion

Target Server Memory

This 16GB DDR3L 1600 CL11 ECC registered DIMM is built for Supermicro X9 series motherboards including X9DBU, X9DR3, X9DR7, X9DRD and X9DRE. It serves workstations, servers, NAS systems and routers that require registered error-correcting memory.

Compatibility Check

Verify your board is one of the listed Supermicro X9 models and that the memory slots accept 240-pin DDR3L registered modules. This module will not work in standard desktop computers and cannot be mixed with unbuffered memory.

Thermals and Power

The module operates at 1.35V without a heat spreader, relying on system airflow for cooling. Registered buffering adds minimal latency while the low voltage keeps power draw modest in typical server workloads.

Questions about this item

What comes in the box and is anything else needed to install it?

The box contains one 16GB DDR3L 1600 CL11 ECC registered RDIMM. No extra parts or cables are required; the module plugs directly into a 240-pin DDR3 slot on a compatible Supermicro X9 motherboard.

Which capacity or version should I choose for my Supermicro X9 board?

This is a single 16GB 2Rx4 module. Choose it when you need one 16GB stick; add a second identical module if your board supports dual-channel and you want 32GB total.

What does the 1600 CL11 rating mean once the module is running in my server?

The module operates at 1600 MT/s with CAS latency 11 at 1.35V, delivering PC3L-12800 bandwidth while ECC and registered buffering protect data integrity in Supermicro X9 workstation or server workloads.
