16GB DDR4 2666 ECC Registered Module

This 16GB DDR4 2666 module delivers ECC Registered operation for server workloads. It runs at PC4 21300 speed with CL17 timing and 1.20V voltage. The 1Rx4 organisation suits multi-slot configurations in compatible platforms.

Compatibility Check Before Purchase

Verify that your motherboard supports DDR4 2666 Registered DIMMs and accepts 288-Pin ECC memory. Confirm the platform can address 1Rx4 rank density and operates at 1.20V. Registered modules will not function in consumer boards that require unbuffered memory.

Build Integration Notes

The module fits 288-Pin DDR4 slots without a heat spreader, leaving clearance for tight CPU coolers. ECC Registered operation protects data integrity in always-on environments. Buyers needing unbuffered memory or higher frequencies should select a different specification.
