32GB DDR4 2666 ECC Registered DIMM

This NEMIX RAM module provides 32GB of DDR4 2666 memory in a single 288-pin RDIMM. It operates at 1.2V with CL19 latency and uses a 2Rx4 organisation. ECC and registered buffering are included for data integrity in server environments.

Suited for Micron-compatible servers needing ECC

This module fits systems that require DDR4 2666 ECC RDIMMs validated for Micron platforms. It is not for desktop boards that accept only unbuffered non-ECC DIMMs. Buyers who need unregistered memory or a different speed grade should look elsewhere.

Single 32GB 2Rx4 rank at DDR4 2666

The 2Rx4 rank layout on a 32GB stick determines whether the motherboard can populate all slots at the rated speed. Verify the platform's maximum rank-per-channel limit before ordering.

Questions about this item

Should I buy the 32GB single module or add multiple modules to reach my target capacity?

This is a single 32GB DDR4 2666 RDIMM. Add one module per available slot; each stick provides 32GB at 1.2V with CL19 latency.

What does the 2666MHz rating deliver in a live server?

The module runs at DDR4 2666 (PC4-21300) with CL19 timing. Actual throughput depends on the platform's memory controller and how many channels are populated.

How does the 288-pin ECC RDIMM interface limit what I can install?

The 288-pin RDIMM form factor fits DDR4 RDIMM slots only. ECC and registered signalling require a motherboard that supports both features; it will not work in UDIMM-only or non-ECC platforms.
