This Micron MT18KSF1G72PZ-1G6E1HG is an 8GB DDR3-1600 registered ECC memory module purpose-built for server platforms, ideally suited for virtualization, in-memory databases, and workloads demanding continuous data integrity. Its single-rank x4 configuration and registered signal architecture reduce electrical loading on the memory bus, enhancing stability in high-density deployments, while the low 1.35V operating voltage improves energy efficiency without sacrificing performance.
1. Registered signal buffering stabilizes signal integrity across fully populated server memory channels, preventing data corruption in dense multi-DIMM configurations that host large in-memory databases.
2. Error-correcting code protection silently detects and corrects single-bit errors, delivering the fault-resilient uptime demanded by continuous-operation enterprise virtualization clusters.
3. Operating at just 1.35 volts, the low-power DDR3 design cuts overall energy consumption and thermal stress inside rack servers, which compounds into measurable annual savings at data-center scale.
4. The 1600 MT/s transfer rate supplies ample per-channel bandwidth for concurrently serving dozens of lightweight containerized workloads without becoming a throughput bottleneck.
5. Single Rank x4 organization reduces electrical loading on the memory bus, enabling faster command handling and steadier sub-millisecond response in latency-sensitive financial transaction processing.
Evaluated as an RDIMM with ECC, registered signaling, and low 1.35V operation, the Micron MT18KSF1G72PZ-1G6E1HG is purpose‑built for the server room, not the desktop. Its four defining characteristics translate directly into business continuity and performance in demanding data‑center workloads.
In a dense virtualization cluster hosting dozens of VMs, the integrated ECC actively corrects single‑bit memory errors caused by background radiation — preventing silent data corruption that could crash a critical database or require a full VM restart. Meanwhile, the registered buffer isolates the memory controller from the electrical load of multiple DIMMs, so you can fully populate a server’s 24 memory slots without signal degradation. This stability is non‑negotiable when running an in‑memory database like Redis or SAP HANA, where a single uncorrected error can cascade into financial discrepancies. The 1.35V low‑voltage design curbs thermal output and power consumption node by node, reducing cooling costs across a multi‑rack deployment. And the single‑rank x4 organization lowers latency and improves command‑bus efficiency, allowing faster data retrieval for transaction processing. Together, these features turn raw DRAM chips into an enterprise‑grade asset that upholds service‑level agreements around the clock.
General Virtualization
For light to moderate virtualization hosts, a balanced memory configuration is essential. Populate triple-channel or quad-channel setups (depending on platform) using six or eight identical 8 GB RDIMMs to achieve 48 GB or 64 GB total capacity while maintaining interleaved performance. This provides enough headroom for 10–15 typical VMs and ensures reliable ECC protection in multi-tenant environments.
In-Memory Database
In-memory databases such as Redis or SAP HANA demand maximum capacity and fault resilience. Fill all available DIMM slots with this 8 GB registered ECC module to reach 128 GB or 256 GB on dual-socket servers, enabling large dataset caching without disk spillover. The 1.35 V low-voltage operation reduces thermal stress, which is critical for 24/7 database nodes.
HPC (High-Performance Computing)
HPC clusters benefit from dense, power-efficient memory per node. Configure four or eight modules per server to match the CPU’s memory channels, delivering 32 GB or 64 GB per node with consistent CL11 latency. The registered ECC design ensures data integrity during multi-day simulations, while the single-rank x4 layout permits higher memory bus speeds under full population.
Rigorously tested server memory, compatible with Dell PowerEdge R720, HP ProLiant DL380p Gen8, and IBM System x3650 M4.
Q: Can I mix this MT18KSF1G72PZ-1G6E1HG with other memory modules of different brands or speeds?
A: Mixing different brands or speeds is not recommended for registered ECC memory. It may lead to instability or unbootable systems. For reliable server operation, all modules should match the exact same part number and specifications.
Q: Is this memory compatible with my system?
A: This DDR3-1600 registered ECC RDIMM is compatible with servers based on Intel Xeon E5-2600 v2 series or AMD Opteron 6300 series platforms. Please verify your server’s memory QVL or chipset support for registered DIMMs.
Q: What is the recommended DIMM population order for optimal performance?
A: For a single-rank x4 RDIMM, populate the first slot of each memory channel as per your server manual. Typically, slots are color-coded; start with blue slots for balanced channel configuration to maximize bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No. This server-grade registered memory operates at standard JEDEC profiles only. Overclocking or XMP is not supported as it compromises the error correction and stability required for 24/7 enterprise environments.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. Enterprise-class registered memory has a very low annualized failure rate, typically below 0.5%, under standard operating conditions. Advanced ECC further reduces uncorrected errors.
