This 8GB DDR3-1600 RDIMM leverages registered ECC and a single-rank x4 organization to deliver robust data integrity, making it ideally suited for server environments focused on virtualization and in-memory database workloads. Its 1.35V low-voltage operation minimizes power consumption while the registered signal path and CL11 timings maintain stability under dense memory configurations.
1. ECC error correction actively detects and corrects single-bit memory faults, preventing silent data corruption in financial transaction systems and long-running database instances.
2. Registered signal type amplifies command and address signals, enabling fully loaded memory channels that maximize virtualization density without sacrificing stability.
3. Single Rank x4 organization minimizes electrical loading per module, allowing servers to populate all DIMM slots while maintaining consistent data integrity across memory-intensive hypervisor workloads.
4. 1.35V low-voltage operation cuts thermal design power significantly, reducing cooling demands and energy bills in scale-out data center deployments running 24/7 services.
5. 8 GB capacity per module offers a fault-tolerant building block for moderate virtual machine instances and replicated in-memory caches, keeping multi-tenant SaaS response times predictable.
When you are managing a virtualized cluster or an in-memory database, the stability of your infrastructure is not negotiable. The Micron MT18KSF1G72PZ-1G6J1 is an 8GB DDR3-1600 Registered DIMM built specifically for server environments, and its four defining characteristics directly address the pain points of enterprise workloads. First, Error Correcting Code (ECC) proactively detects and corrects single-bit memory errors, preventing silent data corruption that can crash a trading database or flip a critical record in your ERP system. Second, the Registered signal buffer stabilizes the electrical load on the memory bus, allowing you to populate all channels with multiple DIMMs without compromising signal integrity—this is essential when scaling a VMware ESXi host to support dozens of virtual machines. Third, the low 1.35V operating voltage reduces power consumption and thermal output across a dense rack of servers, lowering your cooling costs and improving long-term hardware reliability. Finally, the combination of 1600MHz speed and single-rank x4 organization delivers balanced bandwidth and latency for memory-caching engines like Redis, where microsecond response times directly impact user experience. This module transforms raw specifications into tangible uptime and performance for your data center.
The 8GB DDR3-1600 ECC Registered DIMM (RDIMM) with 1.35V low voltage is a server-class memory module. For capacity planning:
General Virtualization
Populate all memory channels symmetrically; start with four DIMMs (32GB) for 10–15 light VMs. Increase to eight DIMMs (64GB) for heavier consolidation, keeping channels balanced for consistent performance and ECC reliability.
In-Memory Database
Maximize total capacity by filling every available slot with these 8GB RDIMMs. A dual-socket server with 16 slots can reach 128GB, ECC protection ensuring no data corruption. For larger working sets, fully populate to avoid disk I/O bottlenecks.
High-Performance Computing (HPC)
Install one DIMM per channel (eight modules, 64GB) to achieve maximum memory bandwidth. The 1.35V operation lowers power and thermal footprint in compute clusters. Use identical single-rank x4 modules across all channels to maintain uniform latency in parallel jobs.
Rigorously tested, this server memory is compatible with Dell R720/R620, HP DL380p Gen8, Lenovo RD430, and Cisco C220 M3.
Q: Can I mix this MT18KSF1G72PZ-1G6J1 with other memory modules of different brands or speeds?
A: Mixing RDIMMs of different brands or speeds is not recommended. It may cause signal instability, POST failures, or memory errors. Optimal reliability requires identical modules per channel, matching rank, voltage, and CAS latency.
Q: Is this memory compatible with my server system? Which platforms are supported?
A: This 8GB DDR3L-1600 ECC Registered DIMM is validated for Intel Xeon E5-2400/2600 v1/v2 and AMD Opteron 6300 platforms. Verify your board supports 1.35V RDIMMs with 240-pin slots and x4 organization.
Q: What is the recommended DIMM population order for optimal server performance?
A: Install identical RDIMMs in groups of matching channels, populating the farthest slot from the CPU first (usually blue or black). For this single-rank x4 module, follow the platform’s memory-population guide to balance interleaving across memory controllers.
Q: Does this module support overclocking or XMP profiles?
A: No, this is a JEDEC-compliant server ECC RDIMM. Overclocking and XMP profiles are not supported, as they compromise data integrity. It runs strictly at DDR3-1600 with CL11 timings at 1.35V for guaranteed stability.
Q: What warranty and typical failure rate can I expect for this memory?
A: This Micron module includes a 1-year warranty. Enterprise-grade testing ensures an annualized failure rate (AFR) typically below 0.1%. ECC scrubbing further mitigates soft errors, making it exceptionally reliable for 24/7 operation.
