Designed for legacy server platforms, this 32GB DDR3-1333 RDIMM leverages Quad Rank x4 organization and Registered signaling to deliver high-density memory capacity and stable operation in multi-DIMM configurations. Its ECC support ensures data integrity for critical workloads like virtualization and in-memory databases, while the 1.35V low operating voltage reduces power consumption without sacrificing 1333MHz performance at CL9 latency.
1. ECC error correction safeguards transactional data against silent corruption, ensuring financial and database workloads maintain full integrity under 24/7 operation.
2. Registered signal buffering stabilizes high-capacity memory arrays, allowing dense server configurations to scale without compromising command bus reliability.
3. A 32GB module empowers virtualization hosts to pack more VMs per node, maximizing consolidation ratios while reducing costly server sprawl.
4. Quad Rank x4 organization doubles the module’s logical bank count, sustaining heavy multi-threaded throughput in memory-hungry enterprise applications.
5. 1.35V low-voltage operation trims datacenter power draw and cooling demands, directly lowering total cost of ownership per gigabyte served.
The Samsung M393B4G70DM0-YH9Q3 is a server-grade DDR3 Registered DIMM, purpose-built for data centers where reliability and uptime define business outcomes. In a virtualized cluster running dozens of mission-critical VMs, its ECC protection is non-negotiable: it immediately corrects single-bit memory errors caused by cosmic radiation or electrical noise, preventing silent data corruption that could crash a hypervisor or corrupt a financial transaction. The Registered signal buffer on this 240-pin module keeps command signals stable even when all memory channels are fully populated, which means you can scale to 32 GB per DIMM without sacrificing signal integrity—a make-or-break requirement when allocating large memory pools to memory-hungry databases like SAP HANA.
Meanwhile, the Quad Rank x4 organization packs 32 GB into a single module, maximizing density for in-memory analytics where loading entire datasets into RAM cuts query latency from seconds to milliseconds. Combined with 1.35V low-voltage operation, it measurably reduces power draw and cooling load across a rack of servers, lowering TCO in always-on environments. For the IT architect, these characteristics translate directly into fewer application errors, more VMs per host, and a cooler, more efficient data center floor.
General Virtualization
This Samsung 32GB DDR3-1333 RDIMM suits density-focused virtualization hosts. For a typical dual-socket server, populate at least six identical modules per processor to balance quad-rank loading while maintaining three memory channels per CPU. Aim for 192–384 GB per host to comfortably support 20–40 mixed- workload VMs, keeping an eye on the reduced 1333 MT/s speed when all channels are fully populated.
In-Memory Database
Quad-rank 32GB RDIMMs allow substantial capacity in a compact footprint, which is ideal for in-memory datasets. Maximize total RAM by filling all slots of a 2-socket system—24 DIMMs deliver 768 GB—but be aware that quad-rank DIMMs may force the memory controller to drop to 1066 MT/s or lower depending on the server platform. Validate latency sensitivity against CL9 timings and consider populating only two DIMMs per channel (384 GB total) if consistent 1333 MHz speed is critical.
High-Performance Computing
For throughput-oriented HPC workloads, balance capacity and memory bandwidth. Install six 32GB RDIMMs per CPU (192 GB per node) to occupy one DIMM per channel, sustaining the full 1333 MHz speed without rank-induced throttling. In large clusters, this configuration supplies enough memory per core for most parallel simulation and modeling jobs while keeping power draw predictable thanks to the 1.35V low-voltage operation.
Server-grade DDR3 RDIMM rigorously tested for compatibility with Dell PowerEdge R720, HP ProLiant DL380p Gen8, and more.
Q: Can I mix this M393B4G70DM0-YH9Q3 with other memory modules of different brands or speeds?
A: Mixing is not recommended. This registered DIMM requires identical ranks, voltage, and timing parameters. Mixing speeds forces all modules to the lowest common speed, risking stability on server platforms.
Q: Is this memory compatible with my system?
A: It is designed for servers using Intel Xeon E5-2600 v2/v3/v4 or AMD Opteron 6300/8300 series platforms with DDR3-1333 support. Verify your board supports quad-rank 32GB registered ECC RDIMMs.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical DIMMs per channel, starting with blue slots first. For dual-processor systems, balance memory evenly across CPUs. Due to quad-rank design, check platform restrictions on maximum ranks per channel.
Q: Does this module support overclocking or XMP profiles?
A: No. As server-grade registered ECC memory, it adheres strictly to JEDEC DDR3-1333 specifications. There are no XMP profiles, and overclocking is disabled to ensure data integrity in mission-critical environments.
Q: What warranty and typical failure rate can I expect?
A: This Samsung module includes a one-year warranty. Enterprise-class memory exhibits an extremely low annualized failure rate (AFR) of approximately 0.1–0.3% under normal operating conditions with proper cooling.
