Engineer's Note

This DDR3-1333 Registered ECC DIMM, operating at a low 1.35V, is engineered for server platforms running memory-intensive workloads such as virtualization and in-memory databases. Its dual-rank x4 configuration combined with ECC and registered signaling ensures exceptional signal integrity and data reliability under high-density, multi-DIMM configurations.

Technical Specs & Insights

1. ECC protection automatically detects and corrects single-bit memory errors, safeguarding data integrity for mission-critical server workloads and preventing silent data corruption in financial or database transactions.
2. Registered signal buffering allows multiple modules to populate the same channel without degrading signal integrity, enabling massive memory scalability essential for dense virtualization hosts.
3. The low operating voltage reduces overall power draw and thermal stress in densely packed rack servers, leading to measurable savings in data center cooling and energy costs over time.
4. Sixteen gigabyte capacity per stick balances density and cost, allowing IT architects to right-size memory configurations for mid-range virtualization clusters or memory-hungry in-memory analytics.
5. Dual Rank x4 organization interleaves access across internal banks to keep server memory channels saturated, delivering the sustained throughput required by hypervisors juggling dozens of active VMs.

Why These Specs Matter

When you deploy a dense virtualization cluster or run an in-memory transactional database, the Micron 16GB DDR3L RDIMM (MT36KSF2G72PZ-1G4D1HE) becomes your foundation for infrastructure reliability. Its ECC technology actively corrects single-bit errors, eliminating silent data corruption that could crash a hypervisor hosting dozens of virtual machines or instantly invalidate financial records inside a Redis cluster. The registered signal buffer stabilizes command and address lines across fully populated servers, so you can occupy all 24 DIMM slots in a 2U node without signal degradation, directly maximizing VM density without sacrificing stability. The dual-rank x4 organization employs interleaving to sustain higher bandwidth and reduce latency spikes when a database engine scans massive in-memory tables, keeping query response times predictable under load. Finally, the 1.35V low-voltage operation cuts power draw by roughly 20 percent versus standard 1.5V DDR3, shrinking thermal stress and energy bills across hundreds of nodes. For you, that means fewer unexplained outages, transactional integrity you can trust, and a cooler, more cost-efficient data center.

Endurance & Reliability

General Virtualization
In a dual-socket virtualization host, install six or eight 16 GB low-power RDIMMs per CPU to populate all memory channels, delivering 96–128 GB of capacity. This configuration supports 20–30 mixed-workload VMs with sufficient overcommit margin, and ECC reliability safeguards guest stability while 1.35 V operation lowers cooling costs.

In-Memory Database
Maximize capacity by fully populating every DIMM slot with these 16 GB Registered ECC modules. A dual-socket platform with 12 slots per CPU achieves 384 GB, ideal for large in-memory datasets. The dual-rank x4 architecture ensures robust signal quality; configure memory mirroring or sparing to protect against uncorrectable errors.

High-Performance Computing
For bandwidth-sensitive HPC applications, install one DIMM per channel (1DPC)—typically eight modules for 128 GB across quad-channel CPUs—to maintain full 1333 MT/s speed. When capacity dominates, populate two DIMMs per channel for 256 GB using 16 modules, knowing that command rates may relax and frequency could step down slightly.

Verified Compatibility

Rigorously tested for full compatibility with Dell PowerEdge R720, HP ProLiant DL380p Gen8, and Lenovo ThinkServer RD430.
