This 2GB DDR3L-1600 registered ECC module is purpose-built for legacy server platforms running latency-sensitive, integrity-critical workloads such as light virtualization and in-memory database caching. Its 1.35V low-voltage operation, registered command/address buffering, and ECC error correction jointly enhance power efficiency and data reliability, while the single-rank x8 organization reduces electrical loading to maintain signal stability in multi-DIMM configurations.
1. Registered DIMM architecture preserves signal clarity across fully loaded memory channels, preventing downtime in mission-critical virtualization hosts.
2. ECC protection corrects single-bit memory errors on the fly, safeguarding transactional data integrity for financial and database servers.
3. Low-voltage operation reduces overall rack power draw and cooling overhead, directly improving data center energy efficiency metrics.
4. High-throughput transfer speed sustains consistent random-access performance under heavy multi-tenant cloud workloads.
5. Single Rank x8 organization balances electrical loading on the memory bus, allowing reliable population of all DIMM slots in dense server nodes.
The M393B5773DH0-YK0 is a server-class DDR3L Registered DIMM, purpose-built for data centers where uptime and accuracy are non-negotiable. Its first critical feature is ECC error correction, which actively detects and corrects single-bit memory errors caused by cosmic radiation or electrical noise. In an in-memory database like SAP HANA, a silent bit flip could corrupt a financial transaction; ECC eliminates that risk, ensuring your data stays mathematically precise around the clock. Second, the registered signal buffer isolates the memory controller from the electrical load of multiple DIMMs, which becomes essential when building dense virtualization clusters with VMware vSphere. It allows you to pack servers with large RAM pools without signal degradation, preventing random crashes during live VM migrations. The third advantage is the 1.35V low-voltage operation, which directly cuts power consumption and cooling costs across a server farm—saving thousands in annual energy bills while reducing thermal stress on components. Finally, the single-rank x8 organization at 1600MHz and CL11 provides a balanced mix of bandwidth and low latency, ideal for its common role as a compact, efficient module for boot drives or dedicated caching tiers. For the enterprise, this memory means hardened reliability, predictable performance under virtualization pressure, and a leaner operating budget.
General Virtualization
For lightweight virtualized environments, install six to twelve 2 GB RDIMMs per server (12–24 GB total) spread evenly across all memory channels. Use identical modules in each channel to maintain balanced access and maximize DDR3-1600 bandwidth. This setup suits small business hypervisors and container hosts where moderate density meets energy-efficient 1.35 V operation.
In-Memory Database
Achieve higher capacity by fully populating all DIMM slots with these low-voltage 2 GB RDIMMs—often 18 or 24 modules for 36–48 GB configurations. Symmetric channel filling preserves ECC reliability and consistent CL11 latency, which is critical for data integrity in Redis or Memcached nodes. For larger datasets, consider higher-capacity DIMMs, but this module remains viable in scale-out clusters where per-node memory is modest.
High-Performance Computing
Populate at least one DIMM per memory channel (typically 8 to 16 modules) to deliver 16–32 GB of registered memory at 1600 MT/s. Full channel population maximizes bandwidth for HPC jobs like fluid dynamics simulations, while the registered buffer stabilizes signal integrity across many ranks. The 1.35 V supply also reduces thermal load in dense rackmount systems, allowing sustained parallel computation with lower cooling overhead.

Q: Can I mix this M393B5773DH0-YK0 with other memory modules of different brands or speeds?
A: Mixing this registered ECC RDIMM with modules of different brands or speeds is strongly discouraged. It risks signal integrity issues, causing server instability or uncorrected errors. Always use identical modules for mission-critical reliability.
Q: Is this memory compatible with my system?
A: This DDR3 registered ECC module fits servers supporting that standard, such as Intel Xeon E5-2600 v2 or AMD Opteron 6300 platforms. Confirm your server board’s qualified vendor list (QVL) for exact compatibility before purchase.
Q: What is the recommended DIMM population order for optimal performance?
A: For optimal performance, occupy the first slot of each memory channel first, maintaining balanced capacity across all channels. Refer to your server’s manual for the exact population sequence to ensure full memory bandwidth and interleaving.
Q: Does this module support overclocking or XMP profiles?
A: No, this is enterprise server memory built strictly to JEDEC DDR3-1600 standards. It does not support overclocking or XMP profiles. It prioritizes data integrity and 24/7 stability over speed enhancements.
Q: What warranty and typical failure rate can I expect?
A: This module includes a one-year warranty. With enterprise-grade components and rigorous screening, the annualized failure rate (AFR) is typically well under 0.5%, providing the high reliability required for server environments.
