This DDR3-1600 Registered ECC RDIMM with dual-rank x8 organization and CL11 latency delivers robust signal integrity and data reliability for virtualization platforms and in-memory databases. Its registered design and ECC ensure stable operation in multi-DIMM server configurations, making it ideal for workloads demanding high data integrity and consistent memory bandwidth.
1. ECC protection silently corrects single-bit errors, preserving data integrity for financial transactions and virtualization hosts where even silent corruption is unacceptable.
2. Registered signal buffering stabilizes command and address buses under heavy load, enabling dense memory populations that keep large in-memory databases responsive.
3. Dual Rank x8 organization leverages rank interleaving to maximize sustained channel utilization, reducing latency spikes during simultaneous VM migrations.
4. DDR3 technology delivers a mature, energy-efficient foundation for legacy enterprise workloads, ensuring reliable operation in cost-optimized data center environments.
5. A 1600MHz transfer rate provides sufficient throughput per channel for moderate consolidation ratios, balancing performance with thermal and power constraints in rack-dense deployments.
The M393B5273CH0-CK0 is a server-grade DDR3 Registered DIMM engineered for mission-critical enterprise environments, and its four key characteristics directly answer the real-world pain points of IT infrastructure managers. First, ECC error correction is non-negotiable when you are running a virtualization cluster hosting dozens of VMs—a single bit-flip in memory can corrupt a virtual disk, silently crashing a database or causing a hypervisor fault that brings down an entire service chain. This module catches and corrects those single-bit errors before they cascade into revenue-impacting outages. Second, the Registered signal buffer ensures that when you fully populate all memory channels in a dual-socket server—say, for an in-memory Redis or SAP HANA database—the electrical load on the memory controller remains stable, allowing 24/7 operation at full capacity without the boot failures or random lockups that plague unbuffered DIMMs under heavy load. The dual-rank x8 organization at 1600MHz further boosts interleaving bandwidth, cutting latency by overlapping memory access requests during concurrent database query threads or real-time analytics workloads. At a standard 1.5V with full CE and RoHS compliance, it delivers the predictable thermal envelope and regulatory conformity your data center deployment checklist demands. Simply put, this is not just memory; it is insurance against data corruption and downtime in high-density server platforms.
Server Memory (DDR3 Registered ECC RDIMM)
General Virtualization
For general virtualization hosts, reliability and balanced capacity are key. Populate all memory channels symmetrically with these 4 GB RDIMMs to maintain interleaving and ECC protection. A typical dual‑socket server using 12 modules per socket provides 48 GB per CPU (96 GB total), enabling a moderate number of lightweight virtual machines without performance penalties.
In‑Memory Database
In‑memory databases demand maximum capacity and the lowest latency. Fill every available DIMM slot with these 4 GB modules to achieve the highest possible RAM footprint—often 128 GB or more on quad‑socket platforms. A fully balanced population across all memory controllers prevents NUMA imbalances, keeping data access times uniform for large in‑memory datasets.
High‑Performance Computing (HPC)
HPC workloads require high bandwidth and fault resilience. Install two dual‑rank RDIMMs per memory channel (e.g., 8 modules per processor) to enable rank interleaving and maximize throughput. This configuration delivers the memory concurrency needed for parallel simulations and numerical computations, while the Registered ECC design ensures data integrity during long‑running jobs.
Rigorously tested server memory, compatible with Dell PowerEdge R720, R620, and HPE ProLiant DL380p Gen8.
Q: Can I mix this M393B5273CH0-CK0 with other memory modules of different brands or speeds?
A: Mixing is not recommended. For reliable server operation, all modules should match in type (DDR3 ECC Registered), speed, rank, and capacity. Mismatched DIMMs may cause system instability or failed POST.
Q: Is this memory compatible with my system?
A: This RDIMM suits server platforms supporting DDR3 ECC Registered memory, such as Intel Xeon E5-2600 v1/v2 or AMD Opteron 6300 series. Always verify your motherboard's qualified vendor list (QVL) for exact compatibility.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical RDIMMs per channel, starting with the slot farthest from the CPU. Balance memory across all channels to maximize interleaving and throughput. Consult your server board manual for the specific slot numbering.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-compliant server memory module with fixed timings and registered signal path. It does not support overclocking or XMP, as stability and data integrity take priority in server environments.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. It is built for enterprise reliability, with an expected annualized failure rate (AFR) typically below 0.5% under normal operating conditions, ensuring minimal downtime.
