About the Micron 32GB DDR4-3200 ECC UDIMM 2Rx8 CL22
The Micron DDR4-3200 32GB ECC UDIMM delivers 25,600 MB/s peak bandwidth in a dual-rank, unbuffered form factor built for enterprise reliability.
This MTA18ASF4G72AZ-3G2R module is engineered for mission-critical server environments where data integrity cannot be compromised. Micron's ECC implementation provides real-time error detection and correction across all 72 data and parity bits, protecting against single-bit upsets that could corrupt workloads. The DDR4-3200 speed grade balances performance with thermal efficiency at just 1.2V, while the 22-22-22 primary timings ensure predictable latency across virtualization, database, and high-availability infrastructure deployments. Storage architects and IT procurement teams rely on this configuration for cost-effective capacity expansion in 2-socket and 4-socket systems.
Micron's JEDEC compliance guarantees compatibility with industry-standard platforms, eliminating qualification risk during infrastructure upgrades. Operating across a 0–85°C range, the module sustains performance in varied datacenter cooling scenarios. The 2Rx8 dual-rank organization optimizes memory density while maintaining stable signal integrity on populated DIMM slots.
