This is a server-class DDR3-1333 Registered ECC RDIMM, ideally suited for legacy virtualization hosts, memory-resident databases, and mission-critical workloads where data integrity is non-negotiable. The dual-rank configuration improves interleaving for enhanced throughput under heavy memory access, while registered signaling and ECC ensure signal stability and single-bit error correction in multi-DIMM configurations.
1. ECC error correction actively detects and corrects single-bit memory errors, preventing silent data corruption in always-on server environments where data integrity is non-negotiable.
2. Registered signal buffering stabilizes command and address lines, allowing servers to scale to high-capacity memory configurations without electrical loading penalties, essential for heavy virtualization hosts.
3. Dual Rank organization interleaves accesses across two internal rank groups, boosting effective bandwidth utilization and sustaining throughput under the concurrent memory demands of multiple virtual machines.
4. A 4 GB base module serves as a flexible building block for cost-effective right-sizing of memory pools, aligning with modest database instances or containerized workloads where density scales linearly.
5. DDR3-1333 delivers 10.6 GB/s peak throughput per channel, offering a balanced blend of bandwidth and power efficiency that matches the steady-state I/O needs of mid-tier application servers.
The MT36JSZF51272PZ is an RDIMM, purpose-built for servers where data integrity and uninterrupted operation are non-negotiable. Its ECC technology actively corrects single-bit memory errors caused by background radiation or electrical noise—errors that in a virtualized cluster would silently corrupt a critical hypervisor page and crash dozens of guest machines. That single corrected bit translates directly into platform uptime. The registered buffer isolates the memory controller from excessive electrical loading, enabling you to populate all slots with stable 4GB modules and reach the high capacities that memory databases like Redis demand without signal degradation or boot failures. Meanwhile, the dual-rank organization interleaves data access across two internal sets of chips, delivering meaningfully higher bandwidth per channel. In an in-memory analytics workload, that rank interleaving squeezes out lower latency and faster transaction throughput than a single-rank alternative, keeping your dashboards responsive under concurrent queries. Finally, DDR3-1333 with CL9 provides a proven frequency sweet spot—balancing speed and thermal load inside dense 1U nodes—so your provisioning plan stays consistent without throttling surprises.
The module is a 4GB DDR3-1333 Registered ECC RDIMM (PC3-10600), a server-class memory type providing error correction and signal integrity for multi-socket systems. Capacity planning must consider its small density, requiring careful aggregation to meet modern workload demands.
General Virtualization
Virtualized hosts need large memory pools. With 4GB DIMMs, populate all memory channels with identical modules for balanced NUMA and maximum capacity. A dual-socket server with 12 slots per CPU yields 96GB, enough for light to moderate VM densities. Avoid mixing DIMM types to prevent performance penalties.
In-Memory Database
In-memory databases demand vast RAM and low latency. 4GB modules limit total capacity; they suit small-scale or test environments. Fully populate channels with these dual-rank DIMMs to maximize bandwidth, but plan a migration to higher-density modules when data sets exceed 256GB.
High-Performance Computing (HPC)
HPC workloads need high bandwidth and balanced access. Install one identical 4GB RDIMM per channel to achieve the maximum channel count and avoid performance drops from mixed configurations. For dual-socket nodes, this provides 64–128GB, adequate for compute-bound simulations but insufficient for data-intensive parallelism.
Rigorously tested ECC Registered DDR3 server RAM; compatible with Dell R710, HP DL380 G7, IBM x3650 M3.
Q: Can I mix this MT36JSZF51272PZ with other memory modules of different brands or speeds?
A: Mixing is not recommended. RDIMMs require identical ranks, timings, and ECC Registered specs. Different brands or speeds may cause instability or prevent booting on server platforms.
Q: Is this memory compatible with my system?
A: It is designed for Intel Xeon 5500/5600 series and AMD Opteron 4100/4200 platforms using DDR3 ECC Registered slots. Verify your server board requires 240-pin RDIMMs before purchasing.
Q: What is the recommended DIMM population order for optimal performance?
A: Populate identical DIMMs per channel, starting from the slot farthest from the CPU. Follow the server board’s memory configuration guide to balance channels and maintain triple-channel or dual-channel interleaving.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-compliant DDR3-1333 registered module designed for server stability. XMP and overclocking are not supported and would compromise ECC data integrity.
Q: What warranty and typical failure rate can I expect?
A: It includes a one-year warranty. Enterprise-grade RDIMMs like this exhibit very low failure rates under normal operating conditions, averaging below 0.2% annually in properly cooled environments.
