This 16GB DDR4-2933 registered ECC RDIMM with a dual-rank x8 configuration is purpose-built for dual-socket servers and workstations running virtualization, in-memory databases, and latency-sensitive transactional workloads that demand uncompromising data integrity. Its registered signal buffering stabilizes command and address lines across loaded memory channels, while full ECC correction and dual-rank interleaving combine to deliver reliable throughput and a tangible boost in effective memory bandwidth at high population densities.
1. A 16-gigabyte capacity per module strikes the balance between footprint and density, allowing IT architects to allocate ample memory for moderate virtualization hosts without wasting DIMM slots.
2. The 2933 megatransfers per second data rate elevates memory bandwidth, accelerating database queries and in-memory caching under sustained enterprise workloads.
3. On‑die error‑correcting code detects and corrects bit flips in real time, preserving data integrity for financial transactions and long‑running scientific computations.
4. Registered clock and command buffering stabilizes signal integrity across heavily populated servers, making reliable scaling to multi‑terabyte memory pools practical.
5. Dual‑rank x8 organization maximizes channel interleaving, keeping data streaming efficiently to multiple CPU cores during heavy consolidation of virtual machines.
Designed for mission-critical servers, the M393A2K43DB2-CVF DDR4-2933 Registered DIMM addresses modern data center demands. Its integrated ECC automatically corrects single-bit memory errors, preventing silent data corruption that can crash virtual machines or poison databases. The registered buffer stabilizes signals across fully populated memory channels, meaning your virtualization cluster can scale to terabytes of RAM without boot failures or performance drops. The dual-rank x8 configuration leverages rank interleaving to boost sustained bandwidth, accelerating queries in memory-intensive databases like SAP HANA and Redis. Operating at 2933 MT/s with a CAS latency of CL21, it balances speed and reliability, while the 1.2V supply significantly cuts power consumption across rack servers. For hypervisors hosting dozens of VMs or an in-memory analytics platform processing millions of transactions, this RDIMM delivers data integrity, scalable capacity, and consistent throughput, transforming hardware into a resilient business foundation.
General Virtualization
For general virtualization hosts, this 16GB DDR4-2933 Registered ECC module provides the stability and data integrity necessary for multi-tenant environments. Deploy at least six identical modules per CPU to populate half the memory channels, ensuring balanced performance and capacity headroom for moderate VM densities. Opt for configurations in multiples of six (96GB, 192GB) on dual-socket systems to leverage all available memory bandwidth while preserving future expansion.
In-Memory Database
In-memory databases demand low latency and uncompromising reliability, making ECC RDIMMs essential. With 16GB Dual Rank x8 modules running at 2933 MT/s, install fully balanced configurations — populate every memory channel identically (e.g., eight modules per socket on an 8-channel platform) to maximize interleave and sustain high throughput under heavy cache miss scenarios. Scale to 512GB or more per node by fully populating all DIMM slots, carefully respecting supported rank counts to avoid clock speed downgrades.
High-Performance Computing
HPC workloads benefit from high memory bandwidth and fault-tolerant operation. Configure 16GB RDIMMs in a symmetrical layout across all memory controllers, using one module per channel to achieve peak frequency without throttling. For memory-bandwidth-bound simulations, double the capacity by populating two modules per channel while monitoring any speed drop to 2666 MT/s, and prefer homogeneous dual-rank DIMMs to maintain consistent access times across the cluster.
Rigorously tested, this server RDIMM fits Dell PowerEdge R760, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR650, and more.
Q: Can I mix this M393A2K43DB2-CVF with other memory modules of different brands or speeds?
A: Mixing brands or speeds with this RDIMM is not recommended. It may cause system instability or performance drops. For guaranteed compatibility, always use identical part numbers or validated modules from the server's qualified vendor list.
Q: Is this memory compatible with my system?
A: This module is compatible with servers supporting DDR4-2933 Registered ECC memory, such as Intel Xeon Scalable (2nd Gen or newer) and AMD EPYC 7002/7003 series platforms. Please verify your system's board QVL for this specific M393A2K43DB2-CVF part number.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical DIMMs per channel starting from the farthest slot from the CPU. For dual-socket servers, maintain balanced memory across both processors. Always refer to the system's service manual for exact slot numbering to achieve optimal interleaving.
Q: Does this module support overclocking or XMP profiles?
A: No. As a server-grade Registered ECC DIMM, this module does not support overclocking or XMP profiles. It is engineered to strictly JEDEC standards for 2933MT/s operation, prioritizing data integrity and 24/7 reliability over frequency tuning.
Q: What warranty and typical failure rate can I expect?
A: This M393A2K43DB2-CVF module comes with a one-year warranty. Enterprise-class DDR4 RDIMMs exhibit very low failure rates under normal operating conditions. Actual annualized failure rates are typically well under 1%, backed by Samsung’s rigorous outgoing quality testing.
