This 32GB DDR3-1600 registered ECC RDIMM, operating at a low 1.35V, is engineered for legacy server platforms requiring high memory density and data integrity, making it ideal for virtualization hosts and in-memory databases. Its quad-rank x4 organization maximizes capacity per channel while the registered signal type and ECC ensure signal stability and end-to-end error correction under heavy, sustained workloads.
1. A 32 GB capacity per module maximizes memory density per server, enabling substantial virtualization headroom for hosting additional VMs without compromising performance.
2. ECC protection detects and corrects single-bit errors in real time, crucial for maintaining data integrity in transactional databases and preventing silent data corruption.
3. Registered signaling buffers command and address lines, allowing stable operation with multiple DIMMs per channel and ensuring reliable uptime in large memory configurations.
4. Quad Rank x4 organization packs more memory devices into a single module, delivering ultra-high capacity per slot for memory-constrained applications like in-memory analytics.
5. Operating at 1.35V instead of standard 1.5V reduces power consumption and cooling costs across at-scale datacenter deployments without sacrificing 1600 MT/s speed.
The M393B4G70DM0-YK04 is a server-grade Registered DIMM whose four key characteristics—Registered buffering, ECC, Quad Rank x4, and 1.35V low voltage—solve critical infrastructure challenges. In a virtualization cluster packing dozens of VMs per host, the Registered architecture buffers signal lines, letting you populate all memory slots without electrical loading faults. This means stable scaling to 384GB and beyond, avoiding crashes. ECC silently corrects single-bit errors, imperative when an in-memory database like Redis or a transactional finance application cannot tolerate data corruption from random bit flips. The Quad Rank x4 organization enables rank interleaving, sustaining peak bandwidth under heavy analytical workloads, preventing bottlenecks that stall real-time queries. Moreover, the 1.35V operation shaves nearly 20% off power and heat compared to standard 1.5V DIMMs—in a rack with dozens of modules, that translates to tangible savings in cooling and extended component lifespan. These traits deliver the integrity, density, and efficiency your data center demands.
General Virtualization
A single 32GB Registered ECC DDR3L module provides a solid foundation for modest virtualization hosts running multiple lightweight VMs. For higher consolidation ratios, deploy four identical modules (128GB total) in a balanced population to leverage quad-channel memory architectures and maintain registered ECC reliability. Always populate identical DIMMs per channel to avoid performance penalties and ensure advanced error correction works seamlessly across all ranks.
In-Memory Database
In-memory databases demand maximum capacity and fault tolerance, making this 32GB Quad Rank RDIMM ideal when installed in multiples. Equip dual-socket servers with at least eight modules (256GB) to hold large datasets entirely in RAM while preserving ECC protection against bit errors. Given the quad-rank design, verify platform support for rank limitations and use low-voltage 1.35V modules to reduce thermal load in densely populated systems.
High-Performance Computing
HPC clusters benefit from the combination of registered ECC reliability and the 1600MT/s speed, especially in per-node configurations where memory bandwidth scales with DIMM count. Populate all memory channels evenly—typically four or eight of these 32GB RDIMMs per node—to saturate the memory bus without introducing mixed-rank latency variability. The 1.35V operating voltage lowers overall power draw across hundreds of nodes, directly contributing to better energy efficiency in sustained compute runs.
Validated server memory, tested for seamless compatibility with Dell PowerEdge R720, HPE DL380p Gen8, Lenovo RD640.
Q: Can I mix this M393B4G70DM0-YK04 with other memory modules of different brands or speeds?
A: Mixing this registered ECC module with dissimilar DIMMs is strongly discouraged. Mismatched ranks, timings, or vendors may compromise signal integrity and cause silent data corruption or system instability in server environments.
Q: Is this memory compatible with my system?
A: This DDR3-1600 ECC RDIMM is designed for servers using Intel Xeon E5/E5 v2 or AMD Opteron 4300/6300 series platforms. Please verify that your board supports 1.35V quad-rank x4 registered DIMMs and a 240-pin slot configuration.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identically across memory channels, starting with the first white slot per channel for balanced interleaving. For quad-rank RDIMMs, limit to two modules per channel to maintain 1600MT/s speed; follow your server’s specific population guide.
Q: Does this module support overclocking or XMP profiles?
A: No, this enterprise-grade registered memory operates exclusively at JEDEC-defined settings (DDR3-1600 CL11) to ensure maximum reliability. Overclocking or XMP is not supported, as stability in mission-critical systems takes priority over performance tuning.
Q: What warranty and typical failure rate can I expect?
A: This module is covered by a one-year warranty. As a rigorously screened server component, it exhibits an extremely low annualized failure rate (AFR), typically well below 0.5%, ensuring dependable long-term operation under 24/7 workloads.
