Designed for legacy server platforms, this Samsung M393B2873FH0-YH9 1GB DDR3-1333 RDIMM combines Registered signal integrity with ECC to ensure data reliability in memory-intensive workloads such as lightweight virtualization or dedicated caching appliances. Its 1.35V low-voltage operation and single-rank x8 configuration with CL9 latency deliver a stable, power-efficient footprint ideal for density-optimized 24/7 deployments in aging datacenter environments where error-free uptime is critical.
1. ECC memory instantly detects and corrects single-bit errors, preserving transactional accuracy and eliminating silent data corruption during continuous database operations.
2. Registered DIMMs buffer command and address signals, allowing fully loaded memory channels to scale up virtualization density without sacrificing signal integrity.
3. Low 1.35V operation reduces per-module energy consumption, translating into substantial power and cooling savings across large-scale data center deployments.
4. 1333 MHz clock speed delivers consistent bandwidth for concurrent workloads, ensuring stable response times in multi-tenant hosting and enterprise analytics.
5. Single Rank x8 organization minimizes electrical loading on the bus, enabling all memory slots to be populated while maintaining rated frequency and system stability.
When you deploy a virtualized server cluster or run an in-memory database, a single undetected bit flip can cascade into application crashes, data corruption, and costly downtime. The Samsung M393B2873FH0-YH9 RDIMM is engineered to prevent exactly these failures. Its ECC technology continuously detects and corrects single-bit memory errors, safeguarding the integrity of every transaction in environments like SQL Server or Redis, where silent data corruption is unacceptable. Registered signal buffering enables you to populate all memory channels with multiple DIMMs without compromising command stability, empowering your hypervisor to confidently assign massive memory pools to dozens of virtual machines. Operating at a mere 1.35V, this DDR3-1333 module substantially reduces thermal load and energy costs across rack-scale deployments, a critical advantage when every watt directly impacts your bottom line. The low CAS 9 latency and single-rank construction deliver responsive data access for memory-tiered applications, proving that even in the DDR3 ecosystem, relentless reliability and efficiency are non-negotiable for 24/7 enterprise workloads.
Server Memory Identified
The module (M393B2873FH0-YH9) is a DDR3-1333 ECC Registered RDIMM with 1.35V low-voltage operation. It is designed for legacy server platforms that require reliability and moderate power efficiency. Below is the capacity planning guidance for typical server workloads, assuming these 8 GB modules are used.
General Virtualization
Populate at least six identical modules across three memory channels per socket to balance capacity and interleaving. For a dual-socket host running 20–30 light VMs, install 12 modules (96 GB total) to avoid ballooning while keeping DIMM ranks uniform for consistent latency. Leave two slots per CPU free for future expansion.
In-Memory Database
Maximise capacity within the voltage and rank limits of the memory controller. Use all 12 DIMM slots on a dual-socket board with 8 GB RDIMMs to reach 96 GB, which suits moderate Redis or Memcached instances. Avoid mixing single-rank and dual-rank DIMMs to maintain stable command timing under high throughput.
High-Performance Computing
Deploy fully populated memory channels with one DIMM per channel (one DPC) for peak bandwidth of 1333 MT/s. On a dual-socket node, install 6 modules per CPU (48 GB per socket, 96 GB total) to minimise loading and achieve symmetric NUMA access. Select CL9-latency kits and enable channel interleaving for floating-point workload efficiency.
Rigorously tested, compatible with servers like Dell PowerEdge R720, HP ProLiant DL380p Gen8, and Lenovo ThinkServer RD630.
Q: Can I mix this M393B2873FH0-YH9 with other memory modules of different brands or speeds?
A: Mixing is not recommended for server environments. Different timings, ranks, or voltages may cause instability. Always use identical modules to ensure reliable operation and maintain system integrity.
Q: Is this memory compatible with my system?
A: This is a 240-pin DDR3-1333 registered ECC RDIMM. It supports Intel Xeon and AMD Opteron platforms requiring 1.35V registered DDR3 memory. Verify your motherboard’s qualified vendor list.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server manufacturer’s guide. Typically populate identical modules per channel, starting with the farthest slot from the CPU. Maintain balanced memory across channels for maximum throughput.
Q: Does this module support overclocking or XMP profiles?
A: No. As a server-grade registered ECC DIMM, it strictly adheres to JEDEC DDR3-1333 CL9 specifications. Overclocking or XMP is not supported and would risk data integrity.
Q: What warranty and typical failure rate can I expect?
A: This module includes a one-year warranty. It is built with industrial-grade components for high reliability, yielding an annualized failure rate well below 0.5% under normal server conditions.
