This DDR3-1333 RDIMM with ECC and a registered signal type is engineered for legacy server platforms, where its dual-rank x4 organization and 1.35V low-voltage operation optimize memory density and power efficiency for virtualization hosts or in-memory databases. The combination of ECC error correction and registered buffering ensures heightened data integrity and signal stability under heavy, sustained workloads typical of mission-critical enterprise environments.
1. High-density module capacity lets data centers pack more memory into each server, dramatically increasing virtual machine density and reducing per-VM cost.
2. Integrated ECC continually corrects data corruption, ensuring rock-solid reliability for mission-critical databases and analytics.
3. Registered buffering isolates the memory controller from electrical loading, preserving signal integrity in fully populated server platforms.
4. Dual-rank interleaving boosts sustained throughput, delivering smoother performance under the heaviest concurrent query loads.
5. Low-voltage operation cuts energy draw significantly, lowering utility bills and cooling demands in large-scale server deployments.
When you deploy this Samsung M393B2G70BH0-YH9 module in your data center, you are not simply adding 16 gigabytes of capacity—you are engineering resilience into your infrastructure. This is a DDR3 Registered RDIMM built for servers, and its four defining characteristics translate directly into business continuity.
First, ECC error correction silently detects and corrects single-bit flips, an absolute necessity for in-memory databases like Redis or SAP HANA where even one undetected bit error can corrupt financial transactions. Second, the Registered signal buffer stabilizes the command interface when a system is fully populated with DIMMs, permitting dense virtualization hosts running dozens of VMs without the timing degradations that plague unbuffered memory. Third, the dual-rank x4 organization exploits rank interleaving to sustain higher effective bandwidth: while one rank completes a row cycle, the controller issues reads to the other, which matters when hypervisors concurrently serve storage, networking, and compute workloads. Fourth, the 1.35-volt low-power design—still PC3-10600 compliant—cuts thermal load and energy draw across a full rack, directly trimming cooling costs and extending server lifespan. Together, these features make the module a trust anchor for clusters that must never drop a packet, lose a record, or pause a session.
This 16GB DDR3-1333 Registered ECC RDIMM is designed for server environments, where stability and data integrity are critical. Its low 1.35V operation and dual-rank x4 organization help balance power efficiency with memory bandwidth in multi-slot configurations.
General Virtualization
Populate all memory channels symmetrically to maximize interleaving and avoid NUMA imbalances. Start with one DIMM per channel (e.g., six modules for a triple‑channel platform, yielding 96 GB) and scale evenly as VM density grows, leaving headroom for host overhead and failover capacity.
In-Memory Database
Favor large overall capacity over raw speed, as datasets often need full RAM residency. Fill every slot with identical 16 GB RDIMMs to reach the platform’s maximum—common dual-socket servers can accommodate 256 GB or more. Keep a spare bank populated only if the database engine supports NUMA-aware allocation, reducing remote memory latency.
High-Performance Computing
Maximize memory bandwidth per core by installing the exact number of DIMMs required for full channel population (e.g., eight DIMMs per socket for quad‑channel designs). Uniform, identical modules prevent clock jitter at 1333 MT/s, and the CL9 latency paired with Registered signaling sustains heavy checkpointing and MPI buffer throughput under sustained parallel workloads.
Rigorously tested server memory compatible with Dell R720, R620, HP DL380p G8, Lenovo RD430, Supermicro X9.
Q: Can I mix this M393B2G70BH0-YH9 with other memory modules of different brands or speeds?
A: Mixing different brands or speeds is not recommended in server environments. For guaranteed stability, always install identical M393B2G70BH0-YH9 modules. Mixing may force all DIMMs to the lowest common speed and potentially cause system instability.
Q: Is this memory compatible with my system?
A: This DDR3-1333 registered ECC RDIMM is compatible with server platforms supporting this standard, such as Intel Xeon E5-2600 v2 or AMD Opteron 6300 series. Verify your server board’s QVL list to ensure RDIMM support.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server motherboard manual. Typically, populate identical DIMMs per channel, starting with the furthest slot from the CPU. Balance memory across all memory channels to enable full memory interleaving and maximum throughput.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a server-grade registered DIMM adhering to strict JEDEC DDR3-1333 standards. It does not support overclocking or XMP profiles, as server platforms prioritize data integrity and long-term stability over speed.
Q: What warranty and typical failure rate can I expect?
A: This module comes with a 1-year warranty. Server memory like the M393B2G70BH0-YH9 is designed for 24/7 operation with very low annual failure rates, supported by rigorous screening and high-quality Samsung components.
