Designed specifically for server environments, this 8GB DDR3-1600 RDIMM leverages registered signal buffering and ECC error correction to deliver rock-solid data integrity and stability under sustained heavy loads. Its dual-rank x8 configuration and low 1.35V operating voltage make it an excellent choice for virtualization clusters and memory-intensive database applications where reliable throughput and energy efficiency are paramount.
1. ECC memory actively detects and corrects single-bit errors, safeguarding transactional data integrity in financial or database server workloads.
2. Registered signal buffering stabilizes command and address lines, enabling large-scale memory populations essential for dense virtualization hosts.
3. Dual Rank x8 organization interleaves access across internal banks, elevating effective bandwidth for consistent VM responsiveness under heavy consolidation.
4. 1.35V low-voltage operation reduces overall server power draw and thermal stress, directly lowering cooling costs in rack-dense data centers.
5. 1600MHz clock speed provides a balanced throughput foundation for mid-tier enterprise applications, ensuring smooth concurrent request handling without overprovisioning.
This Micron RDIMM (MT18KSF1G72PDZ-1G6E1FE) integrates ECC, registered buffering, dual-rank x8 organization, and 1.35V low-voltage operation—each critical for reliable data center performance. In virtualized clusters, a single bit-flip without ECC silently corrupts VM memory, risking cascading failures. ECC detects and corrects these errors, preserving workload integrity. The registered buffer stabilizes signals, enabling full population of DIMM slots per channel; this lets you equip hosts with the substantial memory pools hypervisors and in-memory databases demand, without sacrificing speed. The dual-rank layout interleaves access, boosting bandwidth for latency-sensitive operations like real-time analytics and high-frequency transactions in a Redis or SAP HANA instance. Finally, 1.35V operation reduces power draw and heat in dense server racks, lowering cooling costs and improving the long-term stability of 24/7 operations. This translates into less downtime and predictable performance for your business-critical applications.
The provided module is a server-class 8 GB DDR3L-1600 Registered ECC DIMM. For server deployments, plan capacity as follows:
General Virtualization
Virtualized hosts (VMware, Hyper‑V) need balanced capacity and channel bandwidth. Equip each CPU socket with four identical modules to populate all memory channels, delivering 32 GB per socket or 64 GB in a dual‑socket configuration. This configuration enables channel interleaving, sustains 1600 MT/s throughput, and leaves slots open for future growth.
In‑Memory Database
In‑memory workloads like Redis or SAP HANA demand large datasets kept entirely in RAM. Populate every available DIMM slot with these 8 GB RDIMMs; a typical dual‑socket server accepts 16 modules for 128 GB. Maintain identical memory population per CPU to preserve balanced access, while the 1.35 V voltage reduces power and cooling costs in dense racks.
High‑Performance Computing
HPC nodes prioritize low latency and consistent bandwidth. Install one DIMM per memory channel (often eight modules for 64 GB on a dual‑socket node) to run all channels at the full DDR3‑1600 rate without clock throttling. Registered ECC signaling and dual‑rank design maintain signal integrity during sustained parallel computations.

Q: Can I mix this MT18KSF1G72PDZ-1G6E1FE with other memory modules of different brands or speeds?
A: Mixing registered ECC RDIMMs of different brands or speeds is strongly discouraged. It may cause signal integrity issues, prevent proper booting, or force all modules to run at the lowest common latency and speed, undermining stability.
Q: Is this memory compatible with my system?
A: This 8GB DDR3L RDIMM is designed for servers with Intel Xeon E5 series or AMD Opteron platforms. Verify that your board supports low-voltage 1.35V registered ECC 240-pin modules, as unbuffered or standard voltage systems are incompatible.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical DIMMs per memory channel, following the server board’s silkscreen numbering. Typically, install in slots 1, 2, and 3 per channel first, balancing dual-rank modules across all memory controllers for optimal interleaving and bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No. This enterprise-class RDIMM adheres to JEDEC DDR3-1600 standards for reliability. It does not support overclocking, XMP profiles, or aggressive timing adjustments, as those features are unsuitable for mission-critical server environments.
Q: What warranty and typical failure rate can I expect?
A: This module carries a 1-year warranty. As a thoroughly validated enterprise component built with high-quality ICs, it offers a very low annualized failure rate typically under 1%, ensuring stable long-term operation in 24/7 environments.
