Server-grade ECC registered DDR4

This 16 GB DDR4-2666 module uses registered signal processing and on-die ECC to maintain data integrity under continuous server workloads. It is built for Lenovo ThinkSystem SR530, SR550, SR630, SR650, SR950 and ST550 platforms that require registered DIMMs. Workstations or desktops that accept only unbuffered non-ECC memory cannot use this module.

Registered signal steadies sustained throughput

The registered buffer reduces electrical load on the memory controller, allowing stable operation at the rated 2666 MHz speed during prolonged heavy-duty tasks such as rendering or database serving. CL19 latency and 1.20 V operation keep timing predictable when all slots are populated for extended periods.

1Rx4 rank layout decides fit

This module uses a single-rank 1Rx4 organisation that determines how the memory controller addresses the 16 GB capacity. Verify the platform's qualified vendor list for 1Rx4 registered DIMM support before purchase.

Questions about this item

How much heat and power does this 1.20 V registered DIMM produce under continuous load?

The module runs at 1.20 V with registered signal processing, which reduces electrical load on the memory controller and keeps heat output low during all-day server workloads.

What motherboard slot and memory standard are required to install this 16 GB DDR4-2666 stick?

A 288-pin DDR4 DIMM slot supporting PC4-21300 is required; the module is registered ECC, so the platform must accept registered memory.

Will this module work in a ThinkSystem SR650 that already has factory DDR4 installed?

It is validated for ThinkSystem SR650 among other models; matching speed, voltage, rank and registered ECC type with existing modules is recommended for stable operation.
