Capacity 16GB (2 x 8GB)

  • 16 GB dual-channel kit expands server memory capacity
  • DDR4 2133 MHz CL15 rated speed processes data faster
  • ECC registered design detects and corrects memory errors
  • 2 V operation reduces power draw per module
  • 288-pin DIMM form factor fits compatible server slots

Server ECC RDIMM kit

This 16GB kit contains two 8GB DDR4 registered DIMMs with error-correcting code for servers and workstations. Each module runs at 2133 MHz with CL15 latency at 1.2V. The single-rank x8 organisation and 288-pin form factor match DDR4 RDIMM slots in compatible enterprise platforms.

Dual-channel registered memory

The pair installs as a dual-channel kit into DDR4 RDIMM slots that support registered ECC modules. Registered buffering reduces electrical load on the memory controller, freeing electrical headroom for larger populations of DIMMs per channel. Systems must accept ECC RDIMM; desktop and laptop boards will not work.

16GB capacity for mainstream workloads

Sixteen gigabytes handles typical virtualization hosts, database nodes and compute clusters with moderate memory pressure. The 2133 MHz speed and CL15 timing deliver baseline DDR4 throughput; heavier datasets or higher thread counts will exceed this capacity and require larger modules or more slots.

Questions about this item

What is the maximum sustained data rate of the DDR4 2133 modules?

The kit runs at DDR4 2133 MHz, rated PC4-17000, giving a peak transfer rate of 17 000 MB/s per module.

How much heat do the bare modules produce under continuous load?

Without a heat spreader the 1.20 V modules rely on case airflow; they run at standard DDR4 voltage and single-rank density, so thermals are modest in a ventilated chassis.

Which motherboard feature must be present for these registered ECC DIMMs to function?

The board must support DDR4 RDIMM memory with ECC and registered buffering; desktop or laptop platforms will not accept them.
