This registered DDR3L-1600 RDIMM, leveraging a Quad Rank x4 organization and ECC, is purpose-built for virtualization and in-memory database workloads where 32GB capacity per module and data integrity are critical. Its 1.35V low-voltage operation reduces power consumption in dense server deployments while the registered signal type ensures signal stability across fully populated memory channels.
1. High-density capacity enables robust virtual machine consolidation, supporting larger in-memory databases without latency-inducing disk swaps.
2. ECC error correction silently resolves single-bit faults, preserving data integrity in financial transactions and long-running scientific computations.
3. Registered clock buffering stabilizes high-capacity module configurations, maintaining reliable signal timing across fully populated multi-socket platforms.
4. Quad-Rank x4 organization deepens bank interleaving, sustaining peak channel throughput when multiple virtualized workloads compete for memory access.
5. Low-voltage operation reduces overall power draw and thermal output, directly lowering energy and cooling expenses in dense rack-scale server farms.
The M393B4G70DM0-YK0 is a 32GB DDR3-1600 Registered DIMM purpose-built for server environments, where unwavering data integrity, expansive capacity, and energy efficiency are non-negotiable. Its ECC engine is the first line of defense against soft memory errors caused by background radiation, which can silently corrupt calculations. In a virtualized cluster hosting a dozen VMs on a single node, a single uncorrected bit flip can crash an entire hypervisor or corrupt a database record; ECC proactively corrects these errors, ensuring continuous, trusted operation for critical financial or healthcare workloads. The module’s Registered signaling buffers the address and command lines, dramatically reducing the electrical load on the server’s memory controller. This lets you populate all 24 DIMM slots on a dual-socket board without sacrificing signal stability, which is vital for scaling up to 768GB of RAM for dense virtual farms or large in-memory caching layers. Architecturally, the quad-rank x4 design packs massive capacity onto a single stick, maximizing slot utilization. For a memory-resident database like SAP HANA or a real-time analytics engine, this density lets you keep vast datasets entirely in RAM, bypassing disk latency and accelerating transactions to microseconds. Finally, the 1.35V low-voltage operation translates directly into a lower total cost of ownership across a data center: it reduces thermal dissipation by roughly 15% compared to standard 1.5V modules, cutting cooling demands and power bills while extending the operational margin of your aging server fleet.
General Virtualization
For a typical dual-socket virtualization host using this 32 GB DDR3-1600 registered DIMM, populate six to eight identical modules per CPU to balance capacity and memory bandwidth. Aim for 192–256 GB per node so you can comfortably run 20–30 light to medium VMs without overcommitting RAM. Always install modules in matched sets across memory channels to maintain NUMA symmetry and avoid performance penalties.
In-Memory Database
In-memory databases like Redis or SAP HANA demand large, reliable memory pools, making this ECC RDIMM a solid fit. Fill all available DIMM slots with 32 GB sticks to maximize capacity—384 GB or more per server is achievable on dual-socket platforms—and configure mirroring or sparing if your platform supports it. The quad-rank, 1.35 V low-power design helps keep thermal load manageable even in fully loaded configurations.
High-Performance Computing
HPC workloads require consistent, error-free throughput, so deploy one DIMM per populated channel to minimize rank loading and maintain 1600 MT/s speed. For compute nodes, start with 128 GB (four modules) per socket and scale only as the problem set demands. Use the ECC and registered features to protect long-running simulations, and prioritize populating identical slots across processors for uniform memory access.
Rigorously tested server memory compatible with Dell PowerEdge R720/R620, HP DL380p Gen8, and more.
Q: Can I mix this M393B4G70DM0-YK0 with other memory modules of different brands or speeds?
A: Mixing RDIMMs of different brands or speeds is strongly discouraged. It can force downclocking to the slowest module and introduce instability. Use identical M393B4G70DM0-YK0 modules for guaranteed compatibility.
Q: Is this memory compatible with my system?
A: This DDR3-1600 Registered ECC module is designed for dual-socket servers using Intel Xeon E5-2600 v1/v2 or AMD Opteron 6300 series platforms. Please verify your motherboard's QVL for validated compatibility.
Q: What is the recommended DIMM population order for optimal performance?
A: For Quad Rank x4 RDIMMs, populate the first slot of each memory channel (typically blue) before filling remaining slots. Balanced channel loading maximizes throughput; always refer to your server's population guide.
Q: Does this module support overclocking or XMP profiles?
A: No. This server-grade Registered ECC memory does not support overclocking or XMP. It operates at fixed JEDEC-standard DDR3-1600 CL11 timings to ensure maximum data integrity and 24/7 stability.
Q: What warranty and typical failure rate can I expect?
A: This module includes a one-year warranty. As an enterprise-class ECC RDIMM, the typical annualized failure rate is well below 0.5%, reflecting robust design for mission-critical workloads with proper handling.
