Designed for server platforms, this Samsung M393B5273DH0-YH9 4GB DDR3-1333 RDIMM with ECC and registered signal integrity is well-suited for memory-intensive virtualization and in-memory database workloads where data integrity is critical. Its dual-rank x8 configuration and low 1.35V operating voltage improve interleaving efficiency and thermal headroom in dense 24/7 deployments, while CL9 latency ensures responsive memory access.
1. ECC error correction actively detects and fixes single-bit memory faults, safeguarding transactional integrity in always-on financial databases.
2. Registered buffering stabilizes electrical loads on the host bus, enabling densely populated server boards without sacrificing signal reliability.
3. Dual Rank x8 organization saturates the memory channel, delivering steady bandwidth under heavy virtualization consolidation.
4. Low 1.35V operation trims overall rack power draw and cooling overhead, directly lowering total cost of ownership in hyperscale deployments.
5. 1333MHz frequency provides sufficient throughput for legacy enterprise workloads, keeping application response times predictable.
This Samsung DDR3-1333 RDIMM (M393B5273DH0-YH9) delivers four vital capabilities for enterprise servers. ECC protection eliminates silent data corruption that could corrupt a virtual machine’s memory state or break an in-memory database transaction—preserving uptime and accuracy. The registered buffer decouples electrical loading, letting you fully load a 24-slot server with stable signals; this means your hypervisor clusters can confidently scale to high memory density without crashes. Running at an ultra-efficient 1.35V, it cuts power draw per DIMM by roughly 20% compared to legacy 1.5V modules, which translates to lower cooling costs and higher rack consolidation density in a 24/7 data center. Dual-rank x8 construction enables bank interleaving, effectively doubling the effective bandwidth for read-intensive workloads—vital when a Redis cache or real-time analytics engine handles millions of requests. In virtualized environments and database acceleration, these features directly safeguard revenue, shrink operational expense, and maximize throughput.
This DDR3-1333 ECC Registered RDIMM (M393B5273DH0-YH9) is server-grade memory. Capacity planning guidance for key server workloads follows.
General Virtualization
Memory capacity is the primary bottleneck in virtualized infrastructures. Populate all memory channels symmetrically with identical 4GB modules to enable interleaving and NUMA balance. For a typical dual-socket server using three channels per CPU, installing two DIMMs per channel delivers 48GB, comfortably supporting a dozen moderate VMs.
In-Memory Database
Maximizing total RAM is critical for in-memory datasets. Fully populate every available DIMM slot while respecting per-channel rank limits, using identical 4GB RDIMMs. A dual-socket board with 12 slots per CPU can host 24 modules, providing 96GB for larger database caches and ensuring uniform latency and reliability.
High Performance Computing (HPC)
HPC requires peak sustained bandwidth. Install exactly one dual-rank DIMM per memory channel to avoid electrical loading penalties while leveraging rank interleaving. On a quad-channel server, four 4GB modules per socket yield 16GB with optimal throughput, a balanced foundation for bandwidth-sensitive computational workloads.
Your rigorously tested server memory is compatible with Dell PowerEdge R720, HP DL380p Gen8, and Lenovo ThinkServer RD630.
Q: Can I mix this M393B5273DH0-YH9 with other memory modules of different brands or speeds?
A: Mixing modules, especially differing speeds or brands, on a server platform is not recommended. It often forces systems to the lowest common speed and can cause ECC instability, compromising data integrity.
Q: Is this memory compatible with my system?
A: This is a 240-pin DDR3 ECC Registered RDIMM. It is compatible with select Intel Xeon E5/E7 series and AMD Opteron 6300/8300 platforms that specifically require 1.35V dual-rank x8 registered memory. Verify your motherboard's QVL list.
Q: What is the recommended DIMM population order for optimal performance?
A: For dual-socket servers, populate identical DIMMs per channel starting with the furthest slots from the CPU (usually blue connectors). Always follow the platform’s user manual for balanced memory interleaving and maximum throughput.
Q: Does this module support overclocking or XMP profiles?
A: No. As a server-grade Registered DIMM, it operates strictly at JEDEC standard DDR3-1333 CL9 for maximum stability and data integrity. It does not support overclocking, enthusiast XMP profiles, or voltage manipulation.
Q: What warranty and typical failure rate can I expect?
A: This module carries a 1-year warranty. Built with enterprise-grade components and rigorous testing, its annualized failure rate (AFR) is extremely low, typically less than 0.5% under specified operating conditions.
