32 GB DDR4-2666 RDIMM for servers

This 32 GB DDR4 registered DIMM runs at 2666 MT/s with CL19 latency and 1.2 V operation. It targets server and workstation builds that require ECC protection and registered buffering for large memory configurations.

Registered ECC module for multi-DIMM scaling

The registered design reduces electrical load on the memory controller, allowing more modules per channel than unbuffered alternatives. ECC capability detects and corrects single-bit errors to maintain data integrity in always-on workloads.

2Rx4 organisation maximises density

Dual-rank x4 architecture packs 32 GB into a single 288-pin slot, freeing remaining slots for future expansion. No extra cables, brackets or software utilities are included with the module.

Questions about this item

What sustained workload limit appears first with the 2Rx4 registered DDR4 2666 module?

The dual-rank 2Rx4 organisation means the memory controller hits its rank-per-channel ceiling before bandwidth or latency become bottlenecks.

How much heat and power does the 1.2 V registered DDR4 2666 stick produce under continuous load?

At 1.2 V the module draws only a few watts and runs cool enough for passive server airflow; no active cooling is required.

Which motherboard feature must already be present for this ECC registered DDR4 2666 DIMM to function?

The board needs a registered-DIMM memory controller with ECC support and 288-pin DDR4 slots.
