Engineer's Note

This 8GB DDR3-1333 registered ECC RDIMM operating at a low 1.35V is purpose-built for entry-level servers and workstations running virtualization, memory-centric databases, and other integrity-sensitive workloads. Its dual-rank x4 organization combined with the registered signal type reinforces signal stability on multi-DIMM channels, delivering hardware-level error correction and energy-efficient operation to sustain reliable 24/7 performance.

Technical Specs & Insights

1. Registered signal type buffers command and address lines, enabling the CPU to drive more memory modules simultaneously without signal degradation—critical for scaling dense virtualization clusters with predictable uptime.
2. ECC error correction detects and corrects single-bit memory faults in real time, preserving data integrity for financial databases and preventing silent corruption in long-running analytic workloads.
3. Dual Rank x4 organization interleaves accesses across multiple bank groups, keeping data buses fully utilized and reducing latency spikes under sustained multi-tenant traffic.
4. DDR3 technology delivers a proven balance of moderate bandwidth and low power draw, helping legacy server farms extend service life without pushing thermal envelopes beyond safe limits.
5. The 1333 mega transfers per second operating frequency provides a stable baseline bandwidth profile that ensures consistent quality of service for network-attached storage and light container orchestration tasks.

Why These Specs Matter

The Micron MT36KSF1G72PZ-1G4M1F is an 8GB DDR3L RDIMM designed for server environments. Its four core features directly resolve critical data-center pain points. ECC error correction silently scrubs single-bit errors, preventing a flipped bit from corrupting virtual machine states or in-memory database transactions—essential for always-on services. The registered clock buffer re-drives command signals, enabling full population of memory channels with multiple DIMMs without instability, so your virtualization host scales to massive capacities to run many VMs reliably. Operating at 1.35V instead of 1.5V slashes power consumption per module by over 20%, directly cutting electricity and cooling costs across dense server racks. The dual-rank x4 organization leverages rank interleaving to overlap memory accesses, delivering higher effective bandwidth for memory-hungry workloads like real-time analytics and large database queries. This memory module translates these specifications into real-world data integrity, energy efficiency, and seamless scalability.

Endurance & Reliability

General Virtualization
For light to moderate consolidation, populate each host with at least six of these 8 GB RDIMMs (48 GB total) across balanced memory channels to avoid bottlenecks. The low 1.35 V operation and registered ECC help keep power and cooling costs in check while safeguarding multi-tenant workloads.

In-Memory Database
In-memory platforms demand the lowest latency and highest reliability, so deploy full sets of these modules to reach 128 GB or more per node. The dual-rank x4 design delivers better signal integrity and interleaving gains, directly improving transactional throughput.

High-Performance Computing
Achieve peak memory bandwidth by installing identical 8 GB RDIMMs in a balanced configuration (one DIMM per channel, fully populating all memory channels). ECC is non-negotiable for long-running simulations, and the CL9 latency plus 1333 MHz speed provide a solid baseline for data-intensive parallel tasks.

Verified Compatibility

Rigorously tested, compatible with Dell PowerEdge R620, R720, HP DL360p Gen8, Cisco UCS C220 M3 servers.
