The M393T5750CZ3-CCC is a legacy server-class DDR2-400 Registered ECC RDIMM, ideally suited for aging enterprise platforms running light virtualization or memory-sensitive legacy databases where data integrity is paramount. Its dual-rank x4 organization and low CL3 latency deliver stable, deterministic performance, while the registered signal and ECC engine ensure multi-bit error correction and reliable operation under continuous, moderate loads.
1. ECC error correction actively detects and fixes single-bit memory errors in real time, preserving the integrity of financial transactions and database records on long-running server instances.
2. Registered buffering isolates the memory controller from electrical load spikes, enabling stable multi-DIMM configurations essential for high-density virtualization clusters.
3. Dual Rank x4 organization interleaves memory page accesses to sustain near-peak channel utilization, reducing tail latency for concurrent virtual machine requests.
4. CL3 ultra-tight column access latency cuts read/write round trips to a minimum, giving legacy enterprise workloads deterministic response that compliance-focused systems depend on.
5. A compact capacity targets dedicated baseboard management controllers or redundant boot devices, delivering a cost-efficient footprint for always-on service processors.
When maintaining legacy server infrastructure, every component must earn its place through rock-solid reliability—and this DDR2-400 Registered DIMM delivers exactly that. Built for aging yet indispensable platforms like virtualization clusters and in-memory databases, its four defining characteristics directly address the real fears of IT managers: unexplained crashes, silent data corruption, and unpredictable latency.
First, the Registered buffer acts as a signal amplifier, stabilizing the command bus when all memory channels are fully populated. For a virtualization host running a dozen virtual machines, this means you can maximize capacity without intermittent memory errors dragging down your entire cluster. Second, integrated ECC correction tirelessly scrubs out single-bit flips caused by cosmic rays or electrical noise. In a memory database like a key-value cache, that protection prevents a flipped bit from turning a financial calculation into a costly mistake—the difference between a trusted transaction and a silent logical failure.
Furthermore, the Dual Rank x4 organization enables memory interleaving, giving your hypervisor faster page access and keeping concurrent VMs responsive under heavy load. Finally, the tightly tuned CL3 latency at 400 MHz guarantees deterministic response times—critical for aged ERP systems where timing drift is simply unacceptable. With this module, you are not just buying memory; you are buying insurance for the legacy applications that your business still depends on.
General Virtualization
For legacy servers using DDR2 Registered DIMMs, populate all available channels with identical 2 GB modules to maximize total capacity and interleaving. A typical dual-socket system with eight slots per branch can reach 32 GB, supporting a modest number of lightweight virtual machines. Prioritize balanced DIMM population to maintain memory bandwidth for stable hypervisor operations.
In-Memory Database
ECC is critical for in-memory datasets, so these RDIMMs provide necessary error correction. Deploy the maximum supported module count—often 16 or more across risers—to build a 32–64 GB pool. While 400 MHz limits throughput, the dual-rank design helps sustain acceptable latency; use sparingly for smaller caching layers rather than large production databases.
HPC
Registered DDR2-400 suits older cluster nodes running throughput-oriented scientific codes. Install modules in a power-of-two configuration (e.g., 4 or 8 identical DIMMs per node) to enable full memory interleaving and consistent access times. Even with low clock speed, identical rank and ECC characteristics ensure node uniformity essential for MPI job reliability.
Strictly tested DDR2 registered ECC server RAM, compatible with Dell PowerEdge 2850/1850/2800, HP DL380 G4, and IBM x346.
Q: Can I mix this M393T5750CZ3-CCC with other memory modules of different brands or speeds?
A: Mixing brands or speeds is strongly discouraged. In a Registered ECC server environment, mismatched modules often cause POST failures and system instability. Identical Samsung modules ensure reliable operation.
Q: Is this memory compatible with my system?
A: This DDR2-400 Registered ECC RDIMM is designed for older server platforms such as Intel 5000P/5000X chipset or AMD Socket F systems. Verify your board's qualified vendor list for Samsung M393T5750CZ3-CCC.
Q: What is the recommended DIMM population order for optimal performance?
A: For dual-processor servers, populate corresponding slots per CPU memory channel in matched pairs. Typically, fill the furthest slot from each CPU first. Consult your system's manual for the exact balanced configuration.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-compliant server Registered DIMM designed for maximum data integrity. Overclocking and XMP profiles are not supported; default CL3 timings are fixed for stable 24/7 operation.
Q: What warranty and typical failure rate can I expect?
A: This module comes with a 1-year warranty. As genuine Samsung server-grade memory built with ECC, it offers very high reliability and an extremely low annualized failure rate under normal operating conditions.
