This 32GB DDR3L-1600 Registered DIMM with ECC and quad-rank x4 configuration is purpose-built for legacy enterprise servers and virtualization platforms, where its low 1.35V operating voltage reduces thermal load and its registered signal architecture ensures stable operation across multiple DIMMs per channel. The combination of ECC error correction and a CL11 latency makes it particularly well-suited for memory-centric workloads like in-memory databases and consolidated virtual machine hosting, delivering the data integrity and moderate access speeds required by aging but still-critical infrastructure.
1. 32GB capacity per module enables dense memory configurations, allowing servers to host more virtual machines per physical node without sacrificing performance.
2. Integrated ECC corrects single-bit errors and detects multi-bit faults, preventing silent data corruption in mission-critical databases and financial transactions.
3. Registered signal buffering stabilizes high-capacity memory arrays, ensuring reliable operation when all DIMM slots are populated in enterprise servers.
4. Quad rank x4 organization maximizes capacity per channel, giving data centers the ability to scale up to 256GB per CPU with just eight modules for memory-hungry workloads.
5. Operating at a low 1.35V reduces power consumption and thermal load, which lowers cooling costs and improves overall energy efficiency in large-scale server farms.
The M386B4G70DM0-YK040 is a 32GB DDR3L Registered ECC memory module purpose‑built for mission‑critical servers where data integrity and uptime are non‑negotiable. Its ECC engine silently detects and corrects single‑bit errors in real time, eliminating the silent corruption that could abruptly crash a hypervisor hosting dozens of virtual machines or poison financial records inside a database. In a crowded VMware or Hyper‑V cluster, that protection directly translates to continuous transaction processing without mysterious outages. The registered buffer reliably drives the module’s Quad Rank x4 architecture, enabling you to populate all DIMM slots with dense capacity while preserving rock‑solid signal integrity—vital for in‑memory databases like Redis or SAP HANA that demand a large, stable footprint to serve millions of operations at microsecond latencies. Operating at a low 1.35V, the module further slashes power draw and thermal stress in densely packed racks, lowering cooling overhead and extending hardware lifespan around the clock. This is the kind of resilience that keeps your virtualized workloads and real‑time analytics running without compromise.
General Virtualization
For multi-tenant hypervisors, aim for balanced capacity and bandwidth. Populate four identical 32 GB registered ECC modules across a quad-channel memory controller (one DIMM per channel) to provide 128 GB of reliable, low-voltage DDR3 capacity—ample for moderate VM density. When hosting memory-overcommitted workloads, expand to eight modules (256 GB) while keeping all channels symmetrical to prevent NUMA imbalances and throughput degradation.
In-Memory Database
Maximizing capacity is paramount to hold entire datasets in RAM. Fill every available slot with these 32 GB quad-rank RDIMMs; a dual-socket server can typically accommodate 384 GB using twelve modules per CPU memory controller. Note that quad-rank loading may force the memory controller to downclock from 1600MT/s to 1333MT/s or even 1066MT/s—validate platform specifications and plan for this speed step-down while still prioritizing absolute capacity.
High Performance Computing
Sustained bandwidth drives HPC efficiency. Install a single 32 GB quad-rank RDIMM on each memory channel (e.g., eight modules in an eight-channel, dual-processor node for 256 GB) to exploit full channel parallelism and deep rank interleaving. This configuration delivers the 1600MHz data rate without the signal penalty of multiple DIMMs per channel, ensuring large-scale simulations and floating-point kernels are never starved of memory throughput.
Rigorously validated for seamless operation in Dell R720, HP DL380p Gen8, IBM x3650 M4, and compatible DDR3 servers.
Q: Can I mix this M386B4G70DM0-YK040 with other memory modules of different brands or speeds?
A: Mixing modules is not recommended in server environments. All DIMMs should be identical in speed, rank, and voltage to ensure signal integrity. Mismatched memory may cause boot failures or system instability.
Q: Is this memory compatible with my system?
A: This DDR3-1600 Registered ECC RDIMM is designed for Intel Xeon E5/E7 v1/v2 and AMD Opteron 6300/6200 platforms with C600-series chipsets. Please confirm your board supports 32GB quad-rank x4 modules.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical DIMMs per channel following your server’s memory guide. For dual-socket systems, balance memory across both CPUs and use the highest-rank modules in the first slots of each channel.
Q: Does this module support overclocking or XMP profiles?
A: No, this is an enterprise Registered ECC module operating at JEDEC-standard DDR3-1600 CL11. Overclocking and XMP are not supported, as stability and data integrity are prioritized over speed.
Q: What warranty and typical failure rate can I expect?
A: It is covered by a 1-year warranty. The typical annualized failure rate (AFR) for such enterprise-grade memory is very low, usually below 0.5%, ensuring dependable 24/7 operation.
