The M393B1G70QH0-CK0Q8 is a DDR3-1600 registered ECC RDIMM tailored for server platforms, delivering the data integrity and reliability essential for virtualization, in-memory databases, and mission-critical enterprise workloads. Its single-rank x4 organization and registered signal architecture reduce electrical loading on the memory bus, enabling stable operation at 1600MHz with CL11 latency across fully populated multi-DIMM configurations.
1. ECC protection proactively corrects single-bit memory faults, preserving data integrity for mission-critical workloads like transactional databases and financial processing.
2. Registered signal buffering decouples the memory controller from heavy load, enabling fully populated server boards to maintain rock-solid stability in dense rack configurations.
3. Single Rank x4 architecture balances low latency with efficient channel utilization, delivering predictable throughput for virtualized environments running multiple concurrent instances.
4. An 8 GB module capacity provides a cost-effective building block for scale-out infrastructure, allowing right-sized memory allocation across web-tier and container orchestration nodes.
5. 1600 MHz operation delivers consistent and reliable bandwidth headroom, keeping memory-intensive enterprise applications such as in-memory caches responsive under sustained pressure.
Targeted squarely at server environments, the Samsung M393B1G70QH0-CK0Q8 is an 8GB DDR3-1600 registered DIMM that directly addresses the pain points of data center reliability and performance. Its ECC technology is non-negotiable for virtualized clusters and in-memory databases like Redis or SAP HANA, silently correcting single-bit memory errors caused by cosmic radiation before they cascade into application crashes or silent data corruption—meaning your transactional integrity stays rock-solid even under 24/7 loads. The registered signal buffer stabilizes command and address lines when populating multiple DIMMs per channel, allowing dense, multi-slot server configurations to run heavy virtualization workloads without signal degradation or boot failures, a critical factor when consolidating dozens of VMs onto a single host. The single-rank x4 organization strikes a deliberate balance: it delivers high sustained bandwidth from the 1600MHz clock with lower latency compared to dual-rank setups, enabling faster query responses in memory-hungry database engines while keeping power consumption predictable at the standard 1.5V—essential for managing thermal budgets in constrained rack environments. For any IT team scaling out an ESXi farm or accelerating a real-time analytics platform, this module translates directly into fewer service interruptions, smoother live migrations, and the confidence that your infrastructure can handle growing datasets without compromising on data accuracy.
The Samsung M393B1G70QH0-CK0Q8 is a server-class DDR3-1600 registered ECC DIMM (RDIMM). Capacity planning with these 8GB modules should follow workload-specific guidelines:
General Virtualization
Populate one RDIMM per memory channel (e.g., 8×8GB for 64GB in a dual‑CPU system with four channels each) to enable channel interleaving and efficiently run 20–30 VMs. For heavier consolidation, install a matching second set to obtain 128GB.
In-Memory Database
Maximize capacity by populating all 24 slots of a typical dual‑socket server with 8GB RDIMMs, yielding 192GB. Maintain strictly symmetric configurations across CPUs to avoid NUMA bottlenecks; single‑rank x4 modules ensure full speed and uniform latency.
HPC
Achieve peak bandwidth by installing one 8GB DIMM per memory channel (eight modules in a common 8‑channel dual‑socket server, 64GB total). When datasets exceed this, add a second identical DIMM per channel for 128GB, but verify that the platform sustains 1600MT/s with dual‑DIMM‑per‑channel loading.
Rigorously tested, server-ready RDIMM. Compatible with Dell R720, HP DL380p Gen8, Lenovo RD430, and more.
Q: Can I mix this M393B1G70QH0-CK0Q8 with other memory modules of different brands or speeds?
A: Mixing is not recommended. In server environments, uniform modules ensure signal integrity and stable ECC operation. Mixed brands, speeds, or ranks may cause POST failures or memory errors under load.
Q: Is this memory compatible with my system?
A: This DDR3-1600 RDIMM supports Intel Xeon E5-series and AMD Opteron 6300 platforms. Verify your server board accepts 1.5V registered ECC modules and 240-pin DDR3-1600/PC3-12800 standard. Consult the HCL for BIOS-level validation.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical RDIMMs per channel, starting from the furthest slot from the CPU. Match ranks and capacity. For single-rank x4 modules like this, fill all channels symmetrically to maximize memory bandwidth and interleaving.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a server-grade registered ECC module compliant with JEDEC DDR3-1600 profiles. It lacks XMP and is not designed for overclocking. Operating at 1.5V, it prioritizes reliability over frequency adjustments.
Q: What warranty and typical failure rate can I expect?
A: This module includes a one-year warranty. In production environments, enterprise RDIMMs like this exhibit an annualized failure rate below 0.5% under normal thermal and operational conditions, supported by rigorous Samsung testing.
