This 8GB DDR3-1600 Registered ECC RDIMM employs a single-rank x4 organization to maintain excellent signal integrity and reduced electrical loading in high-density server environments. It is specifically optimized for virtualization platforms and memory-intensive enterprise workloads, where its ECC protection guarantees critical data reliability.
1. ECC error correction empowers the memory to detect and fix single-bit errors automatically, which is foundational for financial databases and virtualization hosts where silent data corruption is simply unacceptable.
2. Registered clock and command buffering dramatically improves signal integrity when populating all memory channels, making this RDIMM the reliable backbone for multi-socket servers that demand maximum memory scalability.
3. 8GB capacity per module offers a sweet spot for dense consolidation, packing enough resources per stick to support a high volume of virtual machines without overcommitting the hypervisor.
4. 1600MHz operating speed translates to PC3-12800 peak bandwidth, effectively handling the concurrent throughput needs of real-time analytics, large in-memory caches, and heavy content-serving platforms.
5. Single Rank x4 organization balances the electrical load on the memory bus while leveraging the enhanced burst-length efficiency of x4 DRAM, resulting in steadier latency profiles under the sustained, mixed-read/write patterns typical of enterprise workloads.
The Micron MT18JSF1G72PZ-1G6D1H is a server-grade DDR3-1600 RDIMM where four critical characteristics directly safeguard your operations: ECC, registered buffering, 1600MHz speed, and single-rank x4 architecture. In a virtualized cluster, a single uncorrected bit flip can silently corrupt a customer database or down a production VM. The ECC engine detects and corrects these errors on the fly, transforming random neutron strikes from business disruptions into non-events. The registered buffer re-drives command and address signals, letting you fully populate all DIMM slots without signal degradation; this is non-negotiable when your VMware host must scale to 256GB of stable memory for dense VM consolidation. At 1600MHz, the module delivers the bandwidth to keep dozens of VMs and in-memory databases responsive, eliminating bottlenecks during peak consolidation. The single-rank x4 chip organization provides finer error correction granularity and lower access latency than dual-rank equivalents. For a Redis or SAP HANA instance processing real-time transactions, this means every microsecond counts and every data point remains unwaveringly accurate. The result is uncompromised data integrity, higher VM density, and consistently fast application response—keeping your enterprise services online and your revenue stream protected.
This 8GB DDR3-1600 ECC Registered DIMM (1.5V, CL11, single-rank x4) is designed for servers. Below is capacity planning advice for typical enterprise workloads.
General Virtualization
Populate one DIMM per memory channel for optimal speed: a quad-channel platform with 4×8GB yields 32GB, adequate for 5–10 light VMs. If capacity outweighs peak frequency, install two DIMMs per channel (8×8GB = 64GB) but verify the platform maintains at least 1333MHz. ECC ensures data integrity for all VMs.
In-Memory Database
Databases like Redis require large, reliable memory. Use these RDIMMs to fill every slot; in a 2-socket server with 24 slots, 24×8GB provides 192GB. Prioritize 1.5V operation to manage power and cooling. The registered design permits high DIMM counts without signal degradation.
High-Performance Computing
Bandwidth-sensitive HPC jobs demand maximum memory throughput. Install exactly one 8GB DIMM per channel to run at the rated 1600MT/s; for example, an 8-channel node uses 8 modules for 64GB. This balanced configuration saturates available bandwidth and minimizes latency, ideal for simulation and modelling codes.
Rigorously tested server memory, compatible with Dell PowerEdge R720/R620, HP DL380p Gen8, and Lenovo ThinkServer RD430.
Q: Can I mix this MT18JSF1G72PZ-1G6D1H with other memory modules of different brands or speeds?
A: Mixing is not recommended. This is a registered ECC RDIMM; using different brands, speeds, or unbuffered DIMMs may cause instability or prevent boot on server platforms.
Q: Is this memory compatible with my Intel Xeon E5-2600 v2 server board?
A: Yes, it is compatible with platforms supporting DDR3 ECC Registered RDIMMs, such as Intel Xeon E5-2600 v1/v2 series. Please verify your board's qualified vendor list for this specific 8GB 1600MHz module.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server motherboard manual. Typically, install identical RDIMMs in groups of four to balance memory channels across CPUs, starting from the first slot of each channel for 4-channel interleaving.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a server-grade Registered ECC DIMM designed for reliability. It operates strictly at JEDEC standard DDR3-1600 CL11 timings and does not support XMP profiles or overclocking.
Q: What warranty and typical failure rate can I expect?
A: This genuine Micron module includes a one-year warranty. Enterprise DDR3 RDIMMs exhibit very low annualized failure rates, engineered for 24/7 operation under rigorous thermal and workload conditions.
