Designed for server platforms, the Samsung M393B5270DH0-CK0Q8 is a DDR3-1600 registered ECC RDIMM that ensures data integrity and system stability for memory-intensive workloads such as virtualization and in-memory databases. Its single-rank x4 organization and registered signal buffering reduce electrical loading on the memory bus, enabling higher capacity scalability and reliable 1.5V operation at CL11 latency.
1. DDR3 memory technology provides a proven, cost-effective foundation for legacy server farms, ensuring stable operation for long-life enterprise applications without unexpected platform migrations.
2. 1600MHz clock speed delivers ample throughput to keep virtualized workloads responsive, preventing I/O bottlenecks during peak database transactions.
3. ECC error correction actively detects and corrects single-bit data corruption, safeguarding critical financial or healthcare records from silent data decay.
4. Registered signal buffering stabilizes command and address lines, enabling the deployment of high-density memory configurations without sacrificing signal integrity across fully populated server boards.
5. Single Rank x4 organization strikes an optimal balance between bank count and electrical load, maximizing memory controller efficiency and improving overall virtualization density per rack.
The Samsung M393B5270DH0-CK0Q8 RDIMM brings four vital attributes to your data center. First, ECC corrects single-bit errors from background radiation or power noise, eradicating silent data corruption that could crash a virtualized finance database and incur massive losses. Second, the Registered buffer stabilizes signal integrity when populating all DIMM slots, which is essential when scaling your virtualization cluster or running a memory-hungry Redis instance—you avoid unexplained boot failures under heavy load. Third, DDR3-1600 (PC3-12800) provides 12.8 GB/s bandwidth, smoothing out throughput during simultaneous live migrations of VMs and speeding up in-memory analytics queries. Fourth, the single-rank x4 organization reduces bus loading to deliver cleaner timings and superior compatibility across multiple modules, making configuration predictable. For you, this translates to higher VM density, hardened data integrity, and fewer emergency pages at 3 AM.
General Virtualization
For general virtualization hosts, the M393B5270DH0-CK0Q8 4GB RDIMM serves as a cost-effective building block. Populate six or eight identical modules per server for 24GB or 32GB total, allowing a hypervisor to comfortably run a dozen light VMs. Always install modules in identical sets across memory channels to maintain balanced NUMA performance and ECC protection.
In-Memory Database
In-memory databases such as Redis or SAP HANA demand both capacity and reliability. Deploy sixteen or more of these 4GB RDIMMs to reach 64GB or higher, fully utilizing all memory channels of a dual-socket platform. The registered ECC design ensures data integrity during sustained high-throughput operations, and the single-rank configuration helps maintain low latency at 1600MHz.
High-Performance Computing (HPC)
HPC clusters benefit from the module’s registered ECC and consistent 1600MHz speed. Install one DIMM per channel across all available slots to maximize bandwidth for memory-bound simulations, targeting 64–128GB per node with 16–32 identical modules. The single-rank x4 organization reduces electrical loading, enabling stable operation when all channels are fully populated under heavy floating-point workloads.
Verified compatible. Rigorously tested for servers: Dell PowerEdge R720/R620, HP ProLiant DL380p Gen8, and more.
Q: Can I mix this M393B5270DH0-CK0Q8 with other memory modules of different brands or speeds?
A: Mixing is strongly discouraged in server environments. Different brands, speeds, or ranks may cause signal integrity issues, system instability, or data corruption. For mission-critical applications, always install identical, fully matched RDIMM kits.
Q: Is this M393B5270DH0-CK0Q8 compatible with my Intel or AMD server platform?
A: It is compatible with servers supporting DDR3 ECC Registered RDIMMs, such as Intel Xeon E5-2600 v1/v2 or AMD Opteron 6300 series platforms. Always verify your motherboard’s memory QVL list to ensure slot and capacity support.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical DIMMs per channel, typically starting with the farthest slot from the CPU (slot 1). For multi-channel configurations, install balanced memory across all channels to maximize bandwidth. Refer to your server board’s specific population guide.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a registered server memory module that operates strictly at JEDEC standard DDR3-1600 (PC3-12800) with CL11. It does not support overclocking or XMP profiles, ensuring maximum stability and data integrity in 24/7 server environments.
Q: What warranty and typical failure rate can I expect?
A: This genuine Samsung module carries a 1-year warranty. Samsung server DRAM demonstrates industry-leading reliability with an annualized failure rate typically below 0.5%, engineered for consistent, long-term operation under enterprise workloads.
