Micron 32GB DDR4-2666 ECC Registered DIMM

This 32GB DDR4-2666 module delivers error-correcting, registered memory for server and workstation platforms that require data integrity. It operates at 1.20V with a PC4-21300 rating. The 288-pin form factor fits standard DDR4 DIMM slots in compatible systems.

Supermicro certified 288-pin build

Supermicro certification confirms the module meets specific platform validation requirements. Registered buffering reduces electrical load on the memory controller, allowing higher capacity configurations. The 288-pin DDR4 interface ensures mechanical compatibility with approved server motherboards.

Upgrades non-ECC or unbuffered DDR4 installations

This module replaces standard unbuffered or non-ECC DDR4 memory when error correction and signal buffering become necessary. The jump is worth it for workloads sensitive to single-bit errors or for motherboards that require registered DIMMs to populate all slots. Buyers needing non-ECC consumer memory should select a different product.
