This is a server-grade DDR3 Registered ECC RDIMM engineered for enterprise platforms that demand high data integrity and multi-rank memory interleaving. Its Dual Rank x4 organization and 240-pin Registered signal topology make it ideal for virtualization hosts and in-memory databases, where ECC corrects single-bit errors and the register buffering stabilizes heavy load across multiple DIMMs per channel.
1. Integrated ECC protection detects and corrects single-bit errors on the fly, safeguarding data integrity for mission-critical virtualization and database operations.
2. Registered buffering strengthens address and command signal integrity, enabling reliable multi-DIMM configurations that underpin dense rack-scale server deployments.
3. A dual-rank design maximizes channel utilization through rank interleaving, sustaining high transaction throughput in multi-tenant cloud environments.
4. Optimized for legacy enterprise platforms, this frequency delivers stable bandwidth and broad compatibility, ensuring dependable performance across mixed-application workloads.
5. The per-module capacity strikes an ideal balance for cost-effective virtualization nodes, allowing flexible memory allocation to numerous lightweight containers and VMs.
The Samsung M393B1K70BH1-CH9 is an 8GB DDR3 Registered ECC server memory module, and its four defining characteristics directly address the real-world pressures of enterprise data centers. ECC error correction is your silent guardian, continuously correcting single-bit memory errors caused by cosmic radiation or electrical noise. In a 24/7 transactional database, this prevents silent data corruption that could otherwise trigger unexplained application crashes or financial discrepancies. The registered buffer stabilizes command and address signals, allowing you to populate every DIMM slot on a server board without signal degradation. For your VMware or Hyper-V clusters hosting dozens of virtual machines per node, this means reliably scaling to hundreds of gigabytes of stable memory. The dual-rank x4 organization employs rank interleaving, which overlaps read and write operations to improve effective bandwidth. This becomes a tangible advantage in in-memory databases like SAP HANA or Redis, where faster data fetches directly accelerate real-time analytics and user response times. Operating at 1333MHz with a CL9 latency and standard 1.5V, the module balances responsive performance with predictable thermal profiles, simplifying cooling in dense rack deployments. For your business, this RDIMM delivers uncompromising data integrity, massive scalability, and consistent performance under continuous load.
General Virtualization
Populate all memory channels evenly with 8 GB DDR3-1333 registered DIMMs. In a typical four-channel server, install eight dual-rank modules (two per channel) for a total of 64 GB. This configuration delivers reliable ECC protection, predictable latency, and sufficient bandwidth to run many virtual machines without overcommitting resources.
In-Memory Database
Maximise capacity by filling every available DIMM slot with identical 8 GB RDIMMs. A dual-socket platform with 24 slots reaches 192 GB, allowing the entire working set to reside in RAM. The registered ECC corrects transient errors under constant high load, protecting data integrity for latency-sensitive transactional and analytical workloads.
High-Performance Computing (HPC)
Start with one dual-rank 8 GB DIMM per memory channel (for example, four modules for 32 GB) to achieve peak 1333 MT/s throughput and lowest electrical load. When larger datasets demand additional capacity, scale to two identical modules per channel (eight modules for 64 GB) while accepting slight timing relaxation from the increased rank count. Consistent part numbers ensure uniform performance across nodes.

Q: Can I mix this M393B1K70BH1-CH9 with other memory modules of different brands or speeds?
A: Strongly not recommended. Mixing Registered ECC modules of different brands, speeds, or ranks can cause server instability. For reliable operation, use identical modules with the same part number throughout the system.
Q: Is this memory compatible with my system?
A: This DDR3-1333 Registered ECC RDIMM works with servers using Intel Xeon 5500/5600 series or AMD Opteron 6100 series platforms. Please verify your server or motherboard model supports 1.5V Registered ECC memory and 240-pin DDR3 slots.
Q: What is the recommended DIMM population order for optimal performance?
A: Always follow your server motherboard's population guide. Typically, populate identical DIMMs per memory channel, starting with slot 1 of each channel. For dual-processor servers, balance memory across all available memory riser and channels to maximize bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No. This is an enterprise-grade Registered ECC DDR3 module running at JEDEC standard 1333MHz (PC3-10600). It does not support overclocking or XMP profiles, as server memory prioritizes data integrity and stability over speed adjustments.
Q: What warranty and typical failure rate can I expect?
A: This module is backed by a 1-year warranty. Enterprise Registered ECC memory typically has a very low annualized failure rate (AFR) of less than 0.5%, thanks to rigorous binning and testing processes designed for 24/7 operation.
