This 2GB DDR3-1333 registered ECC module (PC3-10600, CL9) at 1.35V is designed for small-scale server environments, where its registered signal buffering and single-rank x8 organization deliver stable operation under light virtualization or memory-resident database workloads. The integrated ECC and registered architecture provide critical data integrity and improved signal quality over unbuffered modules, making it well-suited for entry-level servers or microservers that prioritize uptime and error resilience.
1. ECC protection silently corrects single-bit memory errors, preserving data integrity in mission-critical enterprise workloads.
2. Registered signal technology stabilizes high-density memory configurations, enabling reliable scaling for virtualized environments.
3. Low-voltage operation reduces data center power consumption and thermal load, improving long-term reliability.
4. 1333MHz speed delivers dependable bandwidth for hosting concurrent database queries and middleware services without bottlenecks.
5. Single-rank x8 organization minimizes electrical loading on the memory bus, ensuring clean signals for consistent uptime in always-on servers.
The Micron MT9KSF25672PZ-1G4M1HE is a server-grade DDR3 Registered RDIMM, and its four defining characteristics are engineered to solve real pain points in data centers where uptime and accuracy are non-negotiable. ECC memory is not a luxury—in a virtualization cluster running dozens of VMs, a single cosmic ray-induced bit flip can silently corrupt transactional data or crash an entire node. The on-die error correction instantly detects and fixes these errors, preserving data integrity without administrator intervention. Meanwhile, the registered architecture buffers command and address signals, which stabilizes signal integrity when populating multiple DIMMs per channel. This lets you reliably scale memory capacity for hypervisors without sacrificing speed, a critical requirement for dense VMware or KVM estates. For an in-memory database such as SAP HANA or Redis, the single-rank x8 organization and CL9 latency at 1333MHz deliver consistent, low-latency bandwidth critical to query acceleration—every nanosecond saved compounds under heavy load. Additionally, the 1.35V operating voltage cuts power draw and thermal output dramatically across a rack full of servers, lowering cooling costs and extending hardware longevity. These features collectively turn a modest 2GB module into a trustworthy building block for stable, energy-efficient enterprise infrastructure.
This is a server-class DDR3-1333 Registered ECC DIMM (RDIMM) with 2 GB capacity. Capacity planning for server workloads must use multiple modules.
General Virtualization
Install numerous 2 GB RDIMMs evenly across all memory channels to maximize aggregate capacity. A dual-socket server populated with 12 modules (24 GB) supports several light VMs; for moderate loads, 18–24 modules (36–48 GB) provide headroom. Observe vendor population rules.
In-Memory Database
Fill all DIMM slots with identical 2 GB RDIMMs to provide maximum capacity and ECC protection. A 24-slot server yields 48 GB, suitable for moderate in-memory datasets. Enable memory interleaving across channels for higher throughput and scale memory evenly across NUMA nodes.
High-Performance Computing
Populate every memory channel with one or two 2 GB RDIMMs to maximize bandwidth. A dual-socket triple-channel configuration using 12 or 18 modules delivers 24–36 GB at low latency. Low-voltage 1.35V operation reduces power consumption in dense cluster nodes.
Rigorously tested server memory, compatible with Dell PowerEdge R720, HP ProLiant DL380p Gen8, and similar systems.
Q: Can I mix this MT9KSF25672PZ-1G4M1HE with other memory modules of different brands or speeds?
A: Mixing is not recommended for RDIMMs. Different brands or speeds may cause instability. For optimal performance, use identical modules with the same part number, ECC, rank, and timing parameters.
Q: Is this memory compatible with my system?
A: This 2GB DDR3-1333 RDIMM with ECC is designed for server platforms. Verify your server or workstation supports registered DDR3, ECC, 1.35V, and 240-pin RDIMM. Compatible with Intel 5600 series and similar AMD platforms.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server board manual for memory population. Typically, install identical RDIMMs per channel starting with the slot farthest from the CPU. For single rank x8 modules, populate in matched sets for balanced interleaving.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-compliant registered ECC server memory module. It does not support overclocking or XMP profiles. It runs at standard DDR3-1333 frequencies for maximum platform stability and data integrity.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. Enterprise-class ECC RDIMMs like this MT9KSF25672PZ-1G4M1HE exhibit very low failure rates under normal operating conditions, ensuring reliable 24/7 server operation.
