Designed for server platforms, this 8GB DDR3-1333 RDIMM with ECC and registered signal integrity ensures rock-solid data reliability and stability in virtualization and memory-intensive database workloads. Its dual-rank x4 configuration and low 1.35V operation deliver improved interleaving performance and energy efficiency, while the CL9 latency provides responsive data access for demanding enterprise environments.
1. ECC protection corrects single-bit errors and detects multi-bit faults in real time, safeguarding financial transactions and database integrity in mission-critical server environments.
2. Registered signal buffering stabilizes command and address lines across fully loaded memory channels, enabling large-scale virtualization nodes to scale up without signal degradation.
3. Dual Rank x4 organization interleaves memory accesses across two internal ranks, maximizing sustained bandwidth for in-memory analytics and heavily consolidated workloads.
4. 1.35V low-voltage operation reduces data center energy draw and thermal load per DIMM, directly lowering cooling costs in dense rack deployments.
5. 8GB capacity per module offers a dense memory footprint for hypervisors, allowing more virtual machines per server without sacrificing guest responsiveness.
The Samsung M393B1K70DH0-YH909 is a server-grade DDR3 RDIMM, purpose-built for mission-critical enterprise environments where failure is not an option. Its ECC technology actively detects and corrects single-bit memory errors, directly preventing silent data corruption in financial transaction logs or patient records. In a dense virtualization cluster running dozens of VMs on a single host, the Registered signal buffer stabilizes the electrical load on the memory bus, allowing you to populate all DIMM slots without signal degradation—vital for maintaining uptime during live migration. Meanwhile, the Dual Rank x4 organization interleaves memory access across internal banks, boosting throughput for latency-sensitive in-memory databases like SAP HANA or Redis. When a query scans millions of rows, that parallel data access means the CPU is fed faster, shrinking response times under heavy concurrency. Operating at 1.35V, this module also lowers thermal output across a rack full of servers, trimming your cooling costs while safeguarding long-term reliability. From safeguarding database integrity to maximizing consolidation ratios, this RDIMM transforms raw specs into tangible fleet resilience.
This is a server-class DDR3L Registered ECC memory module (RDIMM) designed for enterprise reliability. For capacity planning with this 8 GB, dual-rank, 1333 MHz module, align configuration with workload demand and memory channel architecture.
General Virtualization
Virtualization thrives on ample memory capacity. Start by populating a dual-socket server symmetrically, placing two of these 8 GB RDIMMs per channel across all available channels (e.g., 16 modules for 128 GB). This configuration balances cost with sufficient headroom for moderate virtual machine density while maintaining NUMA affinity and stable ECC protection.
In-Memory Database
In-memory databases demand the lowest latency and large working sets. Fully populate each memory channel with one or two identical 8 GB RDIMMs, respecting the platform’s per-channel rank limits. A common base is 24 modules (192 GB) using a dual-socket, three-DIMM-per-channel layout. The 1.35 V low-voltage operation helps contain power draw, and the registered ECC design ensures data integrity under heavy transactional loads.
High-Performance Computing (HPC)
HPC workloads emphasize sustained memory bandwidth. Install a balanced set of these 8 GB modules with a minimum of one DIMM per channel to exploit all memory controllers. For a dual-socket system with eight memory channels, populate eight identical 8 GB RDIMMs (64 GB total) in a uniform mapping. The dual-rank construction and 1333 MHz speed deliver predictable throughput, while avoiding mixed configurations prevents NUMA bottlenecks and keeps compute nodes tightly coupled.
Rigorously tested server memory. Compatible with Dell PowerEdge R720, HP ProLiant DL380p Gen8, and more.
Q: Can I mix this M393B1K70DH0-YH909 with other memory modules of different brands or speeds?
A: We strongly advise against mixing different brands or speeds in a server. Registered ECC DIMMs must be identical to avoid signal integrity issues, boot failures, or silent data corruption in critical workloads.
Q: Is this memory compatible with my Intel Xeon E5-2400 or AMD Opteron 6300 series server?
A: Yes, it is compatible with select servers supporting DDR3-1333 Registered ECC DIMMs. Please verify your specific motherboard’s Qualified Vendor List, as these platforms benefit from its 1.35V low-power dual-rank design.
Q: What is the recommended DIMM population order for optimal performance in a dual-socket server?
A: Populate identical DIMMs in sets according to your server’s memory architecture guide, typically starting with the slots farthest from the CPU per channel. This dual-rank x4 module balances capacity and ensures balanced memory interleaving.
Q: Does this module support overclocking or XMP profiles?
A: No. As a server-class Registered ECC module, it adheres strictly to JEDEC DDR3-1333 (PC3-10600) specifications. Overclocking and XMP are not supported to guarantee data integrity and 24/7 operational stability.
Q: What warranty and typical failure rate can I expect with this module?
A: This module includes a one-year warranty. It is engineered to enterprise-grade standards, yielding an extremely low annualized failure rate (typically less than 0.5%) in properly cooled and rated server environments.
