This DDR4-2400 Registered ECC RDIMM is engineered for enterprise server platforms, ideally suited for memory-intensive workloads like virtualization and in-memory databases where data integrity is critical. Its quad-rank x4 organization enables high-capacity configurations at 32 GB per module, while the registered signal type enhances stability across densely populated memory channels.
1. Buffered command and address signal architecture maintains signal integrity across fully loaded memory channels, enabling rock-solid stability in dense multi-socket server deployments.
2. End-to-end error correction eliminates silent data corruption, preserving transactional accuracy and around-the-clock database reliability without service interruption.
3. Quad-rank organization maximizes bank-level parallelism per channel, ensuring consistent memory throughput even under extreme virtual machine consolidation and large-scale container orchestration.
4. High per-module capacity allows each server node to host far more virtualized workloads, directly raising consolidation density and lowering operational cost per tenant.
5. Standard server-grade operating frequency delivers ample sustained bandwidth for in-memory analytics and high-concurrency cloud services without exceeding typical thermal envelopes.
The 32GB DDR4-2400 RDIMM (M386A4G40DM0-CRC) is built for enterprise servers. Its four critical features directly mitigate real-world datacenter risks. ECC memory protects against silent data corruption: in a virtualization farm, an uncorrected bit error can crash a hypervisor or silently alter a financial record, but ECC instantly corrects single-bit flips, preserving uptime. The Registered buffer ensures signal integrity when populating all DIMM slots, letting you confidently scale VMs to 128GB and beyond per socket without instability. Quad Rank x4 architecture delivers not only high capacity but also rank interleaving, which significantly boosts bandwidth for memory-hungry applications. This accelerates in-memory databases like SAP HANA and Redis, translating to faster transactions and real-time analytics as the controller pipelines accesses across ranks. The 1.2V low-voltage design reduces power and cooling costs at scale. For your data center, this means bulletproof reliability, denser workloads, and responsive data services—turning memory into a competitive asset.
General Virtualization
For dense virtualization hosts, this 32GB RDIMM provides the capacity and reliability required to run numerous VMs concurrently. Typical dual-socket servers support up to 24 DIMM slots, allowing a balanced configuration of 12 modules per CPU for 384GB total memory. We recommend populating in multiples of eight to maintain optimal memory bandwidth while leaving headroom for future scaling.
In-Memory Database
In-memory databases like Redis or SAP HANA demand low latency and absolute data integrity, making ECC Registered memory essential. With 32GB modules, a 16-slot server can reach 512GB, suitable for moderate in-memory datasets. For larger workloads, maximize slot utilization by installing identical quad-ranked DIMMs evenly across all memory channels to avoid performance penalties.
High Performance Computing (HPC)
HPC clusters require maximum memory bandwidth under sustained loads. Use one DIMM per channel initially to minimize rank loading and maximize frequency headroom. With quad-rank x4 32GB RDIMMs, populate all eight channels of a typical dual-socket server with one module each, delivering 256GB at full 2400MHz speed. Add a second DIMM per channel only if capacity exceeds bandwidth priority, and ensure identical part numbers for uniformity.
Rigorously tested server memory, compatible with Dell PowerEdge R740/R640, HPE ProLiant DL380 Gen10, and Lenovo ThinkSystem SR650.
Q: Can I mix this M386A4G40DM0-CRC with other memory modules of different brands or speeds?
A: Mixing RDIMMs of different brands or speeds is not recommended. It may cause instability, force lower speeds, or disable ECC. Use identical modules to ensure reliable, validated server operation.
Q: Is this memory compatible with my system?
A: This DDR4-2400 Registered ECC module is designed for Intel Xeon E5-2600 v3/v4 and select AMD EPYC servers. Verify your server board supports 32GB quad-rank RDIMMs and a 288-pin interface.
Q: What is the recommended DIMM population order for optimal performance?
A: Refer to your server board's memory population guide. Typically, populate identical 32GB quad-rank RDIMMs per channel, filling first the white slots. Balance across memory controllers for best throughput.
Q: Does this module support overclocking or XMP profiles?
A: No. As a Registered ECC server DIMM, this module adheres to JEDEC DDR4-2400 standards. It does not support overclocking or XMP profiles, as data integrity and stability take priority.
Q: What warranty and typical failure rate can I expect?
A: This module comes with a one-year warranty. In enterprise environments, its AFR is well below 1% under proper conditions, thanks to rigorous screening and Samsung's high-quality fabrication.
