32 GB DDR4-2666 ECC RDIMM for servers

This 32 GB registered DDR4 module runs at 2666 MHz with CL19 latency and 1.2 V operation. It is built for Dell PowerEdge, HP ProLiant, Intel Server System and Supermicro platforms that require ECC RDIMM memory.

Dual-rank 2Rx4 organisation with major-brand chipset

The 2Rx4 layout lets the memory controller access two ranks per channel, increasing density without adding modules. ECC and registered buffering protect data integrity in multi-socket server workloads.

288-pin DIMM installs in standard DDR4 slots

Align the key notch with the slot and press until the latches click. Servers that only accept unbuffered UDIMM or load-reduced LRDIMM cannot use this registered module, so verify the platform DIMM type before purchase.

Questions about this item

Will the registered ECC RDIMM design require any special maintenance or replacement down the line?

No, the module is a solid-state component with no moving parts or serviceable items, so it does not need scheduled maintenance or planned replacement.

What is the first limit reached when the module runs at its rated 2666 MHz speed under sustained load?

The CL19 CAS latency and 1.2 V operating voltage define the timing and power envelope that the memory controller must meet continuously.

How much heat and power does a single 32 GB stick draw when it runs all day in a server?

At 1.2 V the module stays within standard DDR4 power limits, and its low-profile 30 mm height allows normal server airflow to keep temperatures in check.
