This 8GB DDR3-1600 RDIMM with ECC and registered signal type is purpose-built for server platforms, delivering the data integrity and stability required for virtualization and memory-intensive database applications. Its single-rank x4 configuration reduces electrical loading on the memory bus, enabling consistent 1600MHz operation even in fully populated systems while ECC protection guards against single-bit errors in mission-critical workloads.
1. ECC memory detects and corrects single-bit errors in real time, preserving data accuracy for financial databases and compliance-heavy applications where even a silent flip is unacceptable.
2. Registered clock buffering reduces electrical loading on the memory controller, enabling stable operation across fully populated server slots in dense rack deployments.
3. The x4 single-rank organization supports advanced Chipkill protection, letting large-scale virtualization hosts survive multi-DRAM failures without bringing down guest workloads.
4. Eight gigabytes per DIMM give mid-range application servers enough capacity for heavy in-memory caching, significantly lowering storage latency under concurrent user requests.
5. A 1600 MT/s data rate keeps memory bandwidth aligned with multi-core Xeon processors, preventing back-pressure in virtualized environments that run continuous data streaming tasks.
The Micron MT18JSF1G72PZ-1G6E1LG is an 8GB DDR3-1600 registered DIMM purpose-built for server environments, where every component directly impacts business continuity. Its four defining characteristics solve real-world infrastructure pain points rather than simply filling a spec sheet. First, ECC error correction silently scrubs single-bit memory errors triggered by background radiation or electrical noise, a vital defense against silent data corruption that can crash a virtualized cluster or poison financial records in an in-memory database like Redis. Second, the registered buffer decouples the memory controller from the electrical load of multiple DIMMs, enabling you to fully populate channels with 240-pin modules to reach high capacities without the signal degradation that causes unpredictable system halts under heavy virtualization workloads. Third, the 1600MHz clock and 12.8 GB/s peak bandwidth ensure dozens of concurrently running VMs can access data with minimal contention, keeping transaction latencies low. Fourth, the single-rank x4 organization leverages a wider per-chip interface to deliver cleaner signal integrity and reduce rank-switching overhead, so that a database performing rapid-fire key lookups experiences consistently fast response times. You gain longer uptime, denser consolidation ratios, and the confidence that your data remains trustworthy around the clock.
General Virtualization
For a typical virtualization host running multiple VMs, dense memory population is critical. Deploy this 8GB RDIMM in a balanced configuration—six or eight identical modules per CPU socket to populate all memory channels symmetrically, delivering 48–64GB of total capacity while maximizing interleaved bandwidth for dozens of moderate-workload guests.
In-Memory Database
In-memory databases like Redis or SAP HANA demand both capacity and data integrity. Use the maximum supported DIMMs per server, typically 12 to 24 of these 8GB RDIMMs, to reach 96–192GB. The registered ECC design protects against single-bit errors, and CL11 latency is acceptable when the working set fits entirely in DRAM, keeping response times predictable.
High-Performance Computing (HPC)
HPC clusters often balance core count against memory bandwidth. Populate all channels of each node with one DIMM per channel—commonly 8 or 12 modules—yielding a per-node capacity of 64–96GB. This configuration maintains the highest possible DDR3-1600 frequency without degrading to lower speeds under full load, which is essential for simulation and fluid dynamics codes that stream large datasets.
Rigorously tested server DDR3 RDIMM, compatible with Dell R720/R710, HP DL380p Gen8, IBM x3650 M4.
Q: Can I mix this MT18JSF1G72PZ-1G6E1LG with other memory modules of different brands or speeds?
A: Mixing is not recommended. For stable ECC Registered operation, all modules must match speed (1600MHz), rank, and timings. Mismatched specs can cause POST failures or data integrity errors in server platforms.
Q: Is this memory compatible with my system?
A: This is a DDR3-1600 ECC Registered RDIMM for servers. It requires a platform supporting 1.5V Registered DIMMs, such as Intel Xeon E5-2600 v1/v2 or AMD Opteron 6300 series. Verify your motherboard’s RDIMM qualification list.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server motherboard manual. Typically, populate identical DIMMs in corresponding slots per channel first—blue slots then black. For single rank x4 modules, balanced channel loading ensures full memory bandwidth and ECC efficiency.
Q: Does this module support overclocking or XMP profiles?
A: No. This is enterprise-grade server memory built to JEDEC standards. It does not support XMP profiles or overclocking, as stability and error-free ECC operation are prioritized over frequency tuning.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. As a rigorously tested enterprise RDIMM, its typical annualized failure rate is extremely low, meeting server-class reliability standards for 24/7 operation.
