This Samsung M386B4G70BM0-YH901 is a 32GB DDR3-1333 Registered ECC RDIMM engineered for server platforms, ideally suited for virtualization, in-memory databases, and mission-critical workloads where data integrity and stability are paramount. Its quad-rank x4 organization enables high memory density per channel at a low 1.35V operating voltage, while registered signaling and ECC provide the signal integrity and single-bit error correction essential for reliable 24/7 operation.
1. ECC protection constantly corrects single-bit errors and detects multi-bit corruption, safeguarding critical enterprise data integrity in always-on database and virtualization servers.
2. Registered signal buffering re-drives address and command lines, ensuring rock-solid stability when all memory channels are fully populated across multi-socket server boards.
3. A dense 32-gigabyte capacity per module nearly doubles the available memory in a typical dual-processor node, directly expanding VM density and in-memory workload headroom.
4. Quad rank x4 organization maximizes per-channel capacity using narrower DRAM devices, crucial for handling heavy virtualized consolidation without sacrificing manageable rank interleaving.
5. 1333-megatransfer-per-second throughput sustains over ten gigabytes per second of channel bandwidth, efficiently absorbing simultaneous memory requests from dozens of active virtual machines.
The M386B4G70BM0-YH901 is a server-grade DDR3 Registered DIMM, and its design directly addresses the intense demands of enterprise data centers. When you run a dense virtualization cluster hosting dozens of VMs, signal integrity across heavily populated memory channels becomes a real bottleneck. The Registered buffer on this module stabilizes address and command signals, allowing you to install multiple Quad Rank DIMMs per channel without risking data corruption or system crashes. That translates to more virtual machines per server and lower licensing costs. In an in-memory database like a Redis cache or a financial trading system, silent data corruption is unacceptable. Integrated ECC continuously detects and corrects single-bit errors, safeguarding transactional accuracy 24/7. Furthermore, the low 1.35V operating voltage might seem incremental, but across a fleet of servers it slashes power consumption and cooling overhead, while Quad Rank x4 organization packs 32GB into a single slot, maximizing density. This efficiency lets you scale memory capacity for analytics workloads without sacrificing uptime or pushing thermal envelopes, giving you a tangible advantage in total cost of ownership.
General Virtualization
For general virtualization hosts, balance capacity and performance by installing one 32GB quad-rank RDIMM per memory channel. This populates a dual-socket server with 16 DIMMs (512GB total) while maintaining full 1333MHz speed and reliable ECC protection, as a single quad-rank DIMM per channel avoids the command-rate and speed penalties of multi-DIMM configurations. The low 1.35V operation also reduces overall power consumption in dense virtual machine deployments.
In-Memory Database
Maximize capacity for in-memory databases by using two DIMMs per channel, acknowledging a potential speed drop to 1066MHz or 800MHz with quad-rank modules. A fully populated 24-slot dual-processor system can reach 768GB, allowing large datasets to reside entirely in RAM. Pair this with the registered ECC reliability to protect data integrity under heavy transactional loads, and prioritize capacity over peak frequency for massive caching layers.
High-Performance Computing (HPC)
For HPC workloads sensitive to latency and bandwidth, deploy a single 32GB RDIMM per channel, identical to the virtualization baseline, to keep memory running at 1333MHz with CL9 timings. This configuration avoids interleaving penalties and delivers consistent low-latency access for tightly coupled parallel tasks. Complement with the 1.35V low-voltage design to improve energy efficiency across cluster nodes without sacrificing error correction capabilities.
Rigorously tested, compatible with Dell PowerEdge R720, HP ProLiant DL380p Gen8, and similar servers.
Q: Can I mix this M386B4G70BM0-YH901 with other memory modules of different brands or speeds?
A: Mixing with different brands or speeds is not recommended. This may cause instability or fail POST. For reliable operation, install identical RDIMMs with the same 1333MHz speed, rank, and voltage.
Q: Is this memory compatible with my server system?
A: It is compatible with servers supporting DDR3-1333 ECC Registered DIMMs, such as Intel Xeon E5-2600/E5-2400 series or AMD Opteron 6300 platforms. Please verify your motherboard's qualified vendor list.
Q: What is the recommended DIMM population order for optimal performance with this module?
A: Populate identical Quad Rank DIMMs per channel according to your server manual. Typically, fill blue slots first across memory channels, then black slots, balancing load for best interleaving and bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No, this server-grade Registered ECC DIMM does not support overclocking or XMP. It runs strictly at JEDEC standard DDR3-1333 CL9 for maximum stability and data integrity in enterprise environments.
Q: What warranty and typical failure rate can I expect for this module?
A: You receive a 1-year warranty. Under proper operating conditions, the annualized failure rate is exceptionally low, typically below 0.5%, reflecting enterprise-grade reliability and rigorous testing.
