Designed for server-class deployments, this Samsung M393A2K43BB0-CPB 16GB DDR4-2133 RDIMM leverages ECC and registered signal technology to ensure data integrity and signal stability in dense, multi-DIMM configurations. Its dual-rank x8 organization and CL15 latency make it an optimal choice for virtualization platforms and in-memory databases, where consistent, error-free throughput under sustained loads is critical.
1. ECC detects and corrects single-bit errors in real time, protecting in-flight data integrity for mission-critical databases and financial transactions.
2. Registered clock and command buffering stabilizes signal integrity across fully loaded memory channels, enabling reliable scaling to terabytes per server.
3. Dual Rank x8 organization keeps rank-level interleaving active, saturating the memory bus during heavy virtualization and concurrent analytics workloads.
4. A 16GB per module density offers an optimal building block for dense memory configurations, maximizing cost-effective capacity in cloud and enterprise nodes.
5. 1.2V operation curbs aggregate power consumption per rack, directly lowering cooling costs and improving energy efficiency in always-on data centers.
The Samsung M393A2K43BB0-CPB is a server-grade DDR4 RDIMM, purpose-built for enterprise environments where downtime is not an option. Its four defining characteristics directly address the most critical pain points in data centers.
First, the integrated ECC engine silently detects and corrects single-bit memory errors caused by background radiation, preventing data corruption in financial transaction databases or long-running virtualization hosts where a single flipped bit can crash weeks of processing. Second, the registered signal architecture buffers the command and address lines, enabling a single server to support dozens of DIMMs with absolute stability. For a dense virtualized cluster hosting hundreds of virtual machines, this means you can confidently populate all memory channels without sacrificing boot reliability or risking erratic behavior under load. Third, the dual-rank x8 configuration employs interleaving to double the internal bank groups accessible per cycle, raising effective bandwidth. In in-memory databases like SAP HANA or Redis, this translates directly into faster query response and higher real-time analytics throughput under concurrent access. Finally, the 1.2V low operating voltage slashes thermal footprint and cumulative power draw across a rack of servers, lowering your TCO while sustaining 24/7 reliability.
General Virtualization
Deploy multiple M393A2K43BB0-CPB modules in balanced sets across all available memory channels to maximize throughput. For a dual-socket server with six channels per CPU, populate at least one 16 GB RDIMM per channel (12 modules total, 192 GB) to sustain 20–30 typical virtual machines without memory contention. The ECC and registered design ensure stability for mixed workloads running concurrently.
In-Memory Database
This workload demands the lowest latency and highest capacity. Fill every memory channel with this dual-rank 16 GB RDIMM, using two DIMMs per channel (2DPC) if the target capacity exceeds 384 GB, but be prepared for a potential speed drop to 1866 MHz at 2DPC depending on the platform. The 2133 MT/s speed and CL15 timing, combined with ECC protection, support real-time analytics on hot datasets with strong data integrity.
High-Performance Computing (HPC)
Achieve peak memory bandwidth by installing one 16 GB RDIMM per channel across all channels—typically 8 or 12 modules for dual-socket nodes. This one-DIMM-per-channel configuration provides the fastest sustained throughput for bandwidth-sensitive simulations. Dual-rank construction enhances interleaving, and the 1.2 V DDR4 operation keeps power and thermal profiles manageable in dense clusters, making it a cost-effective building block for scalable HPC memory pools.
Proven compatible after rigorous testing with Dell PowerEdge R750, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR650, and other DDR4 ECC servers.
Q: Can I mix this M393A2K43BB0-CPB with other memory modules of different brands or speeds?
A: Mixing modules is not recommended for server environments. Mismatched speeds or brands may cause instability, force all DIMMs to the lowest common speed (2133MT/s), and invalidate validated OEM configurations.
Q: Is this memory compatible with my system? It’s a server platform.
A: This RDIMM is designed for Intel Xeon E5-2600 v3/v4 and select AMD EPYC platforms. Verify that your server board supports DDR4-2133 Registered ECC modules and 16GB dual-rank DIMMs before purchase.
Q: What is the recommended DIMM population order for optimal performance with this module?
A: Populate identical DIMMs per memory channel, starting with the furthest slot from the CPU. Follow your server’s manual for balanced interleaving across channels to maximize throughput and maintain ECC protection.
Q: Does this module support overclocking or XMP profiles?
A: No, ECC Registered server memory does not support overclocking or XMP. It operates strictly at JEDEC standard DDR4-2133 with CL15 timings to ensure data integrity and 24/7 stability.
Q: What warranty and typical failure rate can I expect for this module?
A: It includes a one-year warranty. As an enterprise-grade RDIMM with built-in ECC, typical annualized failure rates are below 0.2% under spec-compliant thermal and workload conditions.
