Optimized for enterprise servers running virtualization and in-memory databases, this 32GB DDR4-2400 RDIMM ensures data integrity with ECC and signal stability through its registered architecture. The quad-rank x4 configuration, operating at CL17 latency, enables high-capacity memory density while maintaining reliable performance in 24/7 mission-critical environments.
1. ECC memory actively detects and corrects single-bit errors in real time, preserving data integrity for financial ledgers and virtual machine states that cannot tolerate silent corruption.
2. Registered buffering relieves electrical loading on the memory bus, allowing fully populated server nodes to maintain signal clarity across dozens of modules under sustained operation.
3. Quad Rank x4 organization interleaves more bank groups to keep the memory channel deeply saturated, preventing bandwidth stalls when hosting dense clusters of containers or analytics instances.
4. The generous per-module capacity allows hyperscalers to pack more virtual machines onto a single physical host, raising consolidation ratios without sacrificing workload isolation.
5. The transfer speed provides steady throughput calibrated for mid-range dual-socket servers, ensuring synchronous data feeds to multiple cores during enterprise backup and replication windows.
The Samsung M386A4G40EM2-CRC is a 32GB DDR4-2400 Registered ECC RDIMM, purpose-built for the relentless demands of enterprise servers where data integrity and uptime are non-negotiable. In a virtualized cluster hosting dozens of VMs, a single undetected bit-flip in memory can cascade into corrupted databases or silent data loss. The integrated ECC actively detects and corrects those errors on the fly, directly safeguarding your transactional consistency and preventing costly application crashes. Its Registered (buffered) design stabilizes signal integrity when populating all 24 DIMM slots in a rack server, allowing you to confidently scale to 768GB or more without boot failures under heavy load—a critical advantage for dense virtualization hosts. Meanwhile, the Quad Rank x4 organization packs twice the bank groups per module, boosting parallelism and bandwidth efficiency for in-memory databases like Redis or SAP HANA. When thousands of concurrent queries hit your real-time analytics tier, this architecture reduces memory access contention, slashing latency under pressure. Combined with the energy-efficient 1.2V operation, it lowers thermal stress in 1U nodes, preserving hardware longevity in your 24x7 data center. This is not just a DIMM—it is a guarantee that your critical workloads stay consistent, responsive, and online.
General Virtualization
Install these 32 GB DDR4 Registered ECC modules in balanced populations across all memory channels. Use one quad‑rank DIMM per channel to sustain the full 2400 MT/s speed, yielding 384 GB to 768 GB in a dual‑socket server with twelve channels. This delivers stable, error‑protected capacity for hosting dozens of virtual machines.
In‑Memory Database
Leverage the high density of quad‑rank 32 GB RDIMMs by fully populating every DIMM slot—reaching 768 GB on a typical 24‑slot server—so entire datasets reside in RAM. ECC and registered signaling guarantee the data integrity required for transactional consistency and real‑time analytics.
High Performance Computing
Maximize memory bandwidth by placing one 32 GB quad‑rank RDIMM per memory channel, avoiding frequency down‑clocking and preserving 2400 MT/s. A dual‑socket, 12‑channel platform configured this way provides 384 GB of balanced, low‑latency memory ideal for parallel simulations and model training.
Server-validated: strict tests confirm compatibility with Dell PowerEdge R760, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR650, and more.
Q: Can I mix this M386A4G40EM2-CRC with other memory modules of different brands or speeds?
A: Mixing is not recommended for RDIMMs. Use identical M386A4G40EM2-CRC modules to avoid signal integrity issues, especially with this Quad Rank x4 design. Different speeds will downclock to the slowest common denominator.
Q: Is this memory compatible with my system?
A: This 32GB DDR4-2400 ECC Registered DIMM is validated for Intel Xeon E5-2600 v3/v4 and Scalable platforms, as well as select AMD EPYC servers. Verify your board supports Quad Rank x4 RDIMMs at 1.2V.
Q: What is the recommended DIMM population order for optimal performance?
A: Install identical DIMMs per memory channel, typically filling all blue slots first across CPU memory controllers. For this Quad Rank module, populate 1 DIMM per channel initially to maintain full speed, balancing across sockets.
Q: Does this module support overclocking or XMP profiles?
A: No. As a server-grade RDIMM, it strictly adheres to JEDEC DDR4-2400/PC4-19200 specifications. Overclocking and XMP are not supported to ensure 24/7 data integrity and ECC reliability.
Q: What warranty and typical failure rate can I expect?
A: This module includes a 1-year warranty. Enterprise RDIMMs exhibit an extremely low annualized failure rate (AFR) under 1%, backed by rigorous factory testing for reliable 24/7 operation.
