16 GB DDR4-2666 ECC RDIMM for servers

This 16 GB registered DDR4 module runs at 2666 MT/s with CL15 latency and 1.2 V operation. It uses a 2Rx8 organisation and 288-pin form factor for compatible server platforms. The ECC registered design helps maintain data integrity in multi-socket systems.

Practical limits of DDR4-2666 registered ECC

Registered modules add a clock cycle of buffering, so maximum usable speed depends on the platform memory controller and populated slot count. Filling every channel at this frequency may require the BIOS to drop to a lower data rate. Total capacity is capped by the number of approved slots per CPU.

Upgrades from lower-capacity or non-ECC DDR4

Replacing smaller RDIMMs with this 16 GB stick increases the virtual-machine density and reduces swapping on memory-constrained hosts. The jump is worthwhile when the workload exceeds the current installed capacity and the motherboard qualifies this part number. Builders needing unbuffered UDIMMs or higher frequencies cannot use this module.

Questions sur cet article

How do I decide between the 16GB 2666 CL15 module and other capacities?

Choose the 16GB 2Rx8 RDIMM when your server has free 288-pin DDR4 slots and the workload needs more ECC registered capacity; match speed and rank to existing modules for best stability.

What does the 2666 MT/s rating mean once the module is installed?

The PC4-21300 DDR4-2666 module transfers data at up to 2666 million transfers per second; actual throughput depends on the platform's memory controller and any down-clocking by the BIOS.

Does the DDR4 288-pin registered interface limit how many modules I can populate per channel?

The registered 2Rx8 design reduces electrical load on the memory bus, allowing higher per-channel DIMM counts than unbuffered modules, but the exact limit is set by the server's memory controller.
