This 64GB DDR4 RDIMM with Registered ECC and an octal rank x4 organization is purpose-built for server platforms running virtualization, in-memory databases, and other data-critical workloads, where its registered signal buffering ensures stable operation in high-density configurations and ECC safeguards against single-bit errors. The deep octal rank design maximizes memory capacity per channel while maintaining signal integrity, and the CL15 latency provides responsive access for heavy multi-threaded processing.
1. A 64GB module density enables higher virtual machine consolidation and larger in-memory database caches, directly boosting data center efficiency.
2. ECC error correction automatically fixes single-bit data errors, safeguarding transactional integrity for mission-critical enterprise workloads.
3. Registered DIMM signal buffering ensures stable operation across fully loaded memory channels, preserving data bus reliability in multi-socket servers.
4. Octal Rank x4 organization packs eight ranks into one module, maximizing memory capacity per slot for dense virtualization and big data analytics without compromising rank interleaving performance.
5. CL15 latency at 2133MHz provides a balanced response profile that keeps latency-sensitive enterprise applications, such as real-time trading and caching, running smoothly.
The Samsung M393A8G40D40-CRB00 is a 64GB DDR4-2133 Registered DIMM purpose-built for enterprise servers, where four defining characteristics directly address the real-world pain points of data centre operators. ECC error correction continuously catches and fixes single-bit flips caused by background radiation or electrical noise, shielding your virtualized multi-tenant clusters and financial transaction logs from the silent data corruption that triggers unexplained crashes and audit failures. The registered buffer isolates the memory controller from the demanding Octal Rank x4 electrical load, preserving rock-solid signal integrity even when every memory channel is fully populated—an absolute necessity for scaling a virtualization host to terabyte-class capacity without instability. A single 64GB module lets you provision far more VMs per hypervisor or expand an in-memory database such as Redis to hold larger, hotter datasets, directly lowering per-gigabyte cost and server sprawl. Thanks to the Octal Rank x4 architecture, aggressive rank interleaving keeps the memory pipeline saturated under heavy database query concurrency, boosting effective bandwidth and cutting latency for real-time analytics. Ultimately, this RDIMM translates to continuous uptime, uncompromising data accuracy, and the headroom your mission-critical workloads demand.
Server Memory Identified
The M393A8G40D40-CRB00 is a 64GB DDR4-2133 Registered ECC RDIMM with octal-rank x4 organization, designed for enterprise servers and workstations. It ensures data integrity in mission-critical environments.
General Virtualization
For virtualized hosts running multiple VMs, populate at least eight identical modules (512GB total) across all memory channels to maximize bandwidth and minimize NUMA latency. Deploying 64GB RDIMMs allows dense VM consolidation while ECC guards against in-memory errors in multi-tenant workloads.
In-Memory Database
In-memory databases like SAP HANA or Redis demand large, reliable capacity. Install twelve modules (768GB) per socket to keep entire datasets resident in RAM. Use balanced configurations across memory controllers to sustain low latency; ECC is non-negotiable for transactional integrity.
High-Performance Computing
HPC clusters require immense aggregate bandwidth. Select dual-socket nodes with 16 DIMMs (1TB) per node, configured as eight modules per CPU. This populates all channels for peak throughput while registered buffers stabilize signal integrity under continuous computational loads.
Rigorously tested server memory, compatible: Dell PowerEdge R730, HPE DL380 Gen9, Lenovo SR650.
Q: Can I mix this M393A8G40D40-CRB00 with other memory modules of different brands or speeds?
A: Mixing is strongly discouraged. This registered ECC module requires identical specifications (DDR4-2133, ECC, RDIMM) for stable operation. Use same part numbers to avoid system instability.
Q: Is this memory compatible with my system?
A: This 64GB DDR4-2133 ECC RDIMM targets server platforms, such as Intel Xeon E5-2600 v3/v4 or select AMD EPYC. Verify your server supports registered ECC memory and 2133MT/s.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical modules per channel, starting with the first slot (e.g., A1, B1, C1, D1). Refer to your server manual for balanced memory interleaving and maximum throughput.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-compliant server module with ECC and registered buffer. Overclocking and XMP are not supported to preserve data integrity and platform stability.
Q: What warranty and typical failure rate can I expect?
A: This module carries a 1-year warranty. Enterprise-grade server memory typically exhibits an annualized failure rate well below 0.1% under normal operating environments.
