This 64GB DDR4-2933 RDIMM with ECC and registered signaling is purpose-built for enterprise server platforms, delivering critical data integrity for memory-intensive workloads such as virtualization and in-memory databases. Its quad-rank x4 configuration maximizes memory density per channel at 1.2V, enabling stable, high-capacity deployments while ECC error correction safeguards against single-bit errors in mission-critical environments.
1. 64GB capacity per module maximizes memory density in server nodes, allowing more virtual machines to run simultaneously without costly hardware expansion.
2. 2933MHz memory speed delivers high bandwidth essential for real-time analytics and database transactions, reducing latency in data-intensive workloads.
3. ECC error correction detects and corrects single-bit errors automatically, safeguarding mission-critical data integrity in 24/7 operation environments.
4. Registered signal type buffers address and control signals, enabling stable operation when populating all memory channels with high-capacity DIMMs in a rack server.
5. Quad Rank x4 configuration fully utilizes the memory bus, sustaining peak throughput even under heavy multi-threaded server workloads.
As a server memory module, the Samsung M393A8G40MB2-CVFC0 RDIMM directly addresses the most pressing challenges in modern data centers. Its 64GB quad-rank x4 design enables extreme memory density, allowing you to provision far more virtual machines per node in a VMware or KVM cluster without expanding your server footprint—this directly reduces licensing and power costs. The integrated ECC engine continuously corrects single-bit errors and detects multi-bit faults, which is non-negotiable for in-memory databases like SAP HANA or Redis where silent data corruption can instantly invalidate financial transactions or model results. Registered buffering stabilizes signal integrity across fully populated channels, so even under the heavy bus loading of a 24-DIMM deployment, your infrastructure maintains uptime and avoids unexplained kernel panics. Furthermore, the 2933 MT/s speed at a low 1.2 V operating voltage strikes a deliberate balance between throughput and thermal efficiency, meaning your cluster sustains peak bandwidth during batch analytics jobs without pushing cooling budgets into the red. Whether you are consolidating a hundred virtual desktops or running a real-time analytics platform, this module transforms memory from a potential point of failure into a foundation of reliability and performance density.
General Virtualization
This 64GB DDR4-2933 RDIMM is ideal for dense virtualization hosts running multiple VMs. Install a minimum of four identical modules in a quad-channel configuration to maximize memory bandwidth and ensure capacity headroom for memory overcommitment. For mid‑range hypervisor servers, populate all memory channels with two modules per channel (2DPC) to reach 512GB total, balancing cost and performance.
In-Memory Database
For latency‑sensitive in‑memory databases like Redis or SAP HANA, quad‑rank x4 modules offer high capacity per slot without sacrificing signal integrity. Deploy six or eight of these 64GB RDIMMs to equip a dual‑socket server with 384–512GB, keeping data entirely in RAM. Enable memory sparing or mirroring if your platform supports it, but note that Registered ECC already guards against single‑bit errors under sustained load.
High-Performance Computing
HPC workloads benefit from the combination of registered ECC and 2933MT/s speed. Populate all eight memory channels on dual‑socket nodes with one DIMM per channel (1DPC) to achieve the lowest latency and full bandwidth. Eight modules deliver 512GB per node, sufficient for large‑scale simulations and computational fluid dynamics while maintaining stable 2933MHz operation under heavy floating‑point throughput.
Server-grade DDR4 RDIMM rigorously tested; compatible with Dell PowerEdge R740, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR650, etc.
Q: Can I mix this M393A8G40MB2-CVFC0 with other memory modules of different brands or speeds?
A: Mixing is not recommended. Registered ECC modules require identical part numbers to maintain signal integrity and avoid system instability. Even same specs from different brands may cause training failures.
Q: Is this memory compatible with my system? I have a dual-socket Intel Xeon server.
A: This DDR4-2933 RDIMM is designed for Intel Xeon Scalable platforms (Purley/Whitley) and AMD EPYC. Verify your motherboard supports 64GB quad-rank x4 load reduced or registered DIMMs and ECC.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical DIMMs per channel, starting with the farthest slot from the CPU. For dual-socket systems, balance capacity evenly across sockets and memory controllers to maximize interleaving.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a server-class Registered ECC DIMM that adheres strictly to JEDEC DDR4-2933 specifications. It does not support overclocking or XMP, ensuring data integrity and RAS compliance.
Q: What warranty and typical failure rate can I expect?
A: It carries a one-year warranty. Enterprise DDR4 ECC RDIMMs like this Samsung module typically have an annualized failure rate (AFR) below 0.5% under proper thermal and voltage conditions.
