Designed for server platforms requiring strict data integrity, this 4GB DDR3-1600 Registered ECC RDIMM with 1.35V low-voltage operation and dual-rank x8 organization enhances memory capacity per channel while reducing power consumption in dense virtualization and in-memory database workloads. Its ECC and registered signal architecture deliver robust error correction and stable signal buffering on 240-pin enterprise boards, making it ideal for reliable, always-on mission-critical deployments where uptime and accuracy are paramount.
1. ECC protection detects and corrects single-bit memory errors silently, preventing silent data corruption in transactional databases and always-on virtualized servers.
2. Registered buffering strengthens signal integrity across fully populated memory channels, making large-capacity configurations stable enough for dense multi-socket host systems.
3. Dual-rank organization enables rank interleaving that reduces access latency under mixed workloads, directly improving consistent VM responsiveness during peak consolidation.
4. Low-voltage operation trims datacenter power consumption and waste heat, helping reduce cooling overhead in high-density rack deployments without sacrificing stability.
5. Mid-tier DDR3 clocking delivers sufficient sustained bandwidth for legacy enterprise workloads, ensuring smooth operation of file services, caching layers, and older application stacks.
The MT18KSF51272PDZ-1G6K is a server-grade registered DIMM, purpose-built for environments where data integrity and uptime are non-negotiable. In a virtualization cluster hosting dozens of VMs, its ECC technology silently corrects single-bit memory errors caused by background radiation, preventing silent data corruption that could crash hypervisors or corrupt critical transactions. Meanwhile, the registered signal buffer stabilizes high-density memory configurations, allowing you to populate all channels without signal degradation — essential when scaling in-memory databases like Redis or SAP HANA that demand both capacity and flawless consistency.
Operating at 1.35V, this low-voltage DDR3-1600 module cuts energy consumption measurably across a rack of servers, reducing cooling costs while sustaining the 1600MHz speed that keeps latency-sensitive financial applications responsive. Its dual-rank x8 architecture further boosts bandwidth by enabling parallel access across ranks, which directly improves performance in virtualized workloads and large SQL databases where memory interleaving translates to faster query execution. For an IT manager overseeing a data center, this RDIMM means confidently running more workloads with fewer errors, lower power draw, and the headroom to grow — it is not just memory, it is risk mitigation engineered into every clock cycle.
General Virtualization
This 4 GB DDR3L-1600 Registered ECC DIMM fits cost‑conscious virtualization hosts. Populate four to eight modules (16–32 GB) evenly across all memory channels to maintain balanced interleaving and reliable throughput for mixed VM workloads. The dual‑rank, 1.35 V registered design helps keep 24/7 power and cooling demands low.
In‑Memory Database
For real‑time analytics and in‑memory caches, fill every available DIMM slot with these 4 GB modules—commonly twelve modules for 48 GB or eighteen for 72 GB. Configure a symmetric 2‑DIMM‑per‑channel layout where the platform permits; the dual‑rank x8 organization and CL11 latency deliver steady access times while ECC guards transaction integrity.
High‑Performance Computing (HPC)
HPC nodes should install one dual‑rank RDIMM per memory channel to sustain the rated 1600 MT/s without down‑clocking. Six or eight modules (24–32 GB) spread identically across channels maximize bank‑level parallelism, giving floating‑point‑heavy simulations the per‑core bandwidth they need. The 1.35 V operation also eases thermal load in dense compute clusters.
Rigorously tested registered DDR3 memory, compatible with Dell PowerEdge R710, HP ProLiant DL380 G7, IBM System x3650 M4, etc.
Q: Can I mix this MT18KSF51272PDZ-1G6K with other memory modules of different brands or speeds?
A: Mixing is not advised. This registered ECC DDR3 module requires identical specifications for stable operation. Different speeds or brands may cause signal integrity issues, system crashes, or unbootable states in server environments.
Q: Is this memory compatible with my Intel Xeon or AMD Opteron server platform?
A: Yes, it is designed for Intel Xeon 5500/5600 series and AMD Opteron 6300 series platforms that support 1.35V DDR3-1600 registered ECC memory. Always verify your motherboard's qualified vendor list for full compatibility.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical dual-rank x8 RDIMMs in groups of three per memory channel, starting with the slots farthest from the CPU. Follow your server board’s population guide to maintain balanced interleaving and maximize data throughput.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a server-grade registered ECC component, locked to JEDEC-standard DDR3-1600 at CL11. Overclocking or XMP profiles are not supported to ensure 24/7 operational stability and data integrity in mission-critical systems.
Q: What warranty and typical failure rate can I expect?
A: It comes with a 1-year warranty. The estimated MTBF exceeds 2 million hours under normal server conditions, resulting in an extremely low annualized failure rate below 0.2%, ensuring long-life reliability.
