This Micron module is a 32GB DDR4 ECC Unbuffered DIMM stick, running at 3200MHz configured as 2Rx8, running at CAS latency CL22. As a ECC Unbuffered DIMM, it combines error-correcting code (ECC) protection with an unbuffered design — aimed at workstation motherboards that support ECC memory without requiring full server-grade registered memory, giving data-integrity protection for professional workloads without the RDIMM-only platform restriction. Matching capacity, speed, and form factor exactly to the target system (and, for a multi-module upgrade, matching modules to each other) is what lets DDR4 memory run reliably at its full rated speed rather than falling back to a slower, auto-negotiated speed or failing to POST altogether. It carries ECC (error-correcting code) protection, which detects and automatically corrects single-bit memory errors on the fly — valuable for workstation and server workloads where a silent, uncorrected memory error could corrupt a long-running calculation, a large dataset, or a rendered result. The module uses 16Gbit density dies. As a dual-rank ECC UDIMM rather than a registered module, this suits a DDR4-generation workstation platform that supports ECC memory without needing a full server-grade registered-memory motherboard. It is offered through Marvel's component catalog with manufacturer warranty backing, aimed at South African system builders, upgraders, and IT professionals sourcing verified, correctly-specified parts rather than guesswork.
