Designed for enterprise server platforms, this Samsung M393A2G40BB0-CPB 16GB DDR4-2133 Registered ECC module ensures data integrity in virtualized environments and memory-intensive databases. Its dual-rank x4 organization and registered signaling enhance signal stability and capacity scaling, while ECC protection detects and corrects single-bit errors to maintain system uptime under continuous operation.
1. Error-correcting code memory silently detects and corrects single-bit data corruption, ensuring transaction integrity in financial databases and other mission-critical enterprise applications that cannot tolerate silent data decay.
2. Registered DIMM technology buffers command and address signals to maintain signal integrity across large memory populations, enabling stable 24/7 operation in fully loaded multi-socket servers.
3. A 16-gigabyte module density gives virtualization hosts the headroom to assign generous memory to each guest, avoiding costly swapping even under high consolidation ratios.
4. Dual Rank x4 configuration interleaves memory accesses across multiple internal banks, keeping server memory channels fully saturated for consistent throughput during heavy virtual machine and analytics workloads.
5. CL15 latency reduces the delay penalty for data fetches, delivering more deterministic response times for latency-sensitive services like in-memory caching and high-frequency trading platforms.
Built for the relentless demands of enterprise data centers, the Samsung M393A2G40BB0-CPB is a 16GB DDR4-2133 registered DIMM engineered to eliminate the hidden costs of server instability. Its ECC technology silently detects and corrects single-bit memory errors caused by background radiation, preventing silent data corruption that can crash a virtualized cluster or poison a financial transaction mid-process. In a 24/7 hypervisor farm hosting dozens of VMs, this means you avoid unexplained kernel panics and database index rebuilds that cripple SLAs. The registered signal buffer decouples the memory controller from raw DRAM loads, enabling a single server to populate all 24 slots without compromising signal integrity—critical when scaling in-memory databases like SAP HANA or Redis, where terabytes of hot data demand flawless operation. Moreover, the dual-rank x4 organization intelligently interleaves access across internal banks, boosting effective bandwidth under heavy parallel queries, so your real-time analytics or OLTP workloads consistently deliver low-latency responses without dropped transactions. This module is not just memory, it is the difference between a profitable, always-on service and a costly outage.
General Virtualization
For a typical hypervisor hosting multiple VMs, populate the server with at least four M393A2G40BB0-CPB modules to reach 64 GB. Use balanced DIMMs across all memory channels (e.g., two modules per CPU in a dual-socket system) to maximize bandwidth and allow future expansion. This registered ECC configuration ensures data integrity and stable overcommitment in mixed-workload environments.
In-Memory Database
In-memory databases demand both capacity and low latency, so a minimum of 128 GB (eight modules) is recommended for moderate-sized datasets. Install identical dual-rank x4 RDIMMs across all channels to maintain symmetric access and highest throughput. The 2133 MHz speed with CL15 provides predictable response times, while registered ECC guards against single-bit errors that could corrupt critical data structures.
High-Performance Computing
HPC workloads scale best with fully populated memory channels to saturate bandwidth. Aim for 256 GB using sixteen modules, splitting them evenly across both sockets to enable efficient NUMA locality. Although 2133 MHz is conservative, the dual-rank x4 design offers sufficient bank parallelism for streaming scientific applications, and ECC is essential when running multi-day simulations.
Server-grade, rigorously tested. Compatible with Dell PowerEdge R750, HPE ProLiant DL380 Gen10, Lenovo SR650, and more.
Q: Can I mix this M393A2G40BB0-CPB with other memory modules of different brands or speeds?
A: Mixing different brands or speeds is not recommended for registered server memory. The system will clock all modules to the slowest common speed, potentially causing instability or POST failures in mission-critical environments.
Q: Is this memory compatible with my Intel Xeon or AMD EPYC server platform?
A: This DDR4-2133 Registered ECC RDIMM is compatible with most Intel Xeon E5-2600 v3/v4 and select AMD EPYC platforms that support 2133MT/s. Always verify your server's qualified vendor list for explicit compatibility.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical DIMMs in balanced channels per your server manual, typically filling blue slots first for channel interleaving. For dual-rank RDIMMs, populate one DIMM per channel initially to avoid bandwidth penalties.
Q: Does this module support overclocking or XMP profiles?
A: No, this is a JEDEC-compliant server RDIMM. It does not support XMP or overclocking. It operates strictly at 2133MHz, CL15, 1.2V to ensure data integrity and stability in enterprise environments.
Q: What warranty and typical failure rate can I expect?
A: This module carries a one-year warranty. Enterprise DDR4 RDIMMs typically have an annualized failure rate (AFR) below 0.5% when operated within specified thermal and voltage limits.
