16GB DDR4 ECC RDIMM for Dell PowerEdge servers

This 16GB registered DIMM targets Dell PowerEdge R550, R640, R740, R740XD and R740XD2 platforms that require ECC registered memory. It is not for standard desktop computers or any system that only accepts unbuffered modules. Builders needing consumer DDR4 should look elsewhere.

Capacity and headroom

The single 16GB module runs at 2933MHz with CL21 latency and 1.2V operation, providing registered ECC reliability for virtualisation, databases and multi-user workloads. Backward compatibility with 2133MHz, 2400MHz and 2666MHz bus speeds lets it slot into existing configurations, though maximum throughput stays at the rated PC4-23400 level.

Registered ECC 2Rx8 organisation

The 2Rx8 registered ECC design is the decisive specification; it must match the motherboard's memory controller requirements exactly. Mixing this module with unbuffered or non-ECC memory will prevent the system from posting, so verify the platform demands registered ECC RDIMMs before purchase.

Questions sur cet article

Will this 2933 MHz ECC registered RDIMM run reliably in a PowerEdge R740 that currently has 2666 MHz modules installed?

The module is backward compatible with 2666 MHz, 2400 MHz and 2133 MHz speeds, so it will operate at the lower frequency of the existing memory without issues.

How can I verify the 16 GB RDIMM is detected and running with ECC active after installation?

Check the system BIOS or iDRAC interface; it will show the new 16 GB capacity, 2933 MHz speed, and ECC registered status for each populated slot.

Does the single 16 GB 2Rx8 RDIMM ship with a heat spreader or any extra cables?

The module has no heat spreader and no cables are included; only the 288-pin DDR4 ECC registered DIMM itself is in the box.
