64 GB DDR4 2666 Registered ECC Module

This 64 GB DDR4 2666 registered ECC module is built for servers and workstations that need large, error-correcting memory capacity. The 288-pin DIMM runs at 1.20 V with a CL17 latency profile. It targets administrators scaling up multi-socket platforms where data integrity matters.

Upgrading from smaller or unbuffered DIMMs

Replacing lower-capacity or non-ECC sticks with this registered module adds 64 GB per slot and enables error correction across the memory bus. The jump is worth it when workloads exceed current physical memory or when uncorrected errors risk silent data corruption in critical applications.

Fits 288-pin DDR4 registered channels

The module installs in standard 288-pin DDR4 registered memory channels that support 1.20 V operation. It frees DIMM slots by delivering 64 GB in a single rank-dense package, leaving room for future expansion within the platform's maximum slot count.

Perguntas sobre este artigo

Will the 288-pin DDR4 module fit my server's DIMM slots?

The module uses the standard 288-pin DDR4 form factor, so it fits any server board with DDR4 registered DIMM slots.

How do I install the registered ECC memory correctly?

Power down the server, open the chassis, align the notch on the 288-pin edge connector with the slot key, press firmly until both retention clips click, then verify the full 64 GB appears in BIOS.

When should I consider replacing the 64 GB DDR4 2666 CL17 kit?

Replace the kit if memory diagnostics report uncorrectable ECC errors, if the system fails to POST at the rated 2666 MT/s speed, or when a platform upgrade requires a different memory generation.
