This 8GB DDR3-1333 RDIMM is purpose-built for entry-level servers and virtualization platforms where registered signaling and ECC ensure critical data integrity under sustained workloads. Its dual-rank x4 configuration optimizes memory interleaving for improved throughput in memory-database and consolidation scenarios, while the 1.35V low-voltage operation and CL9 latency provide an efficient balance of power savings and reliable performance.
1. ECC error correction detects and corrects single-bit memory faults, safeguarding data integrity in mission-critical server environments and preventing silent data corruption.
2. Registered signal buffering stabilizes command and address lines, enabling high-capacity memory configurations essential for large-scale virtualization and database servers.
3. An 8-gigabyte capacity per module supplies ample headroom for multiple virtual machines and memory-intensive workloads, striking an optimal balance between density and cost in scale-out deployments.
4. Dual rank x4 organization interleaves memory accesses across internal ranks, maximizing channel utilization and delivering consistent throughput under heavy transactional loads.
5. Low 1.35-volt operation curbs power draw and thermal output, directly reducing total cost of ownership in dense data center deployments while sustaining full DDR3 performance.
Based on its RDIMM form factor, 240-pin interface, ECC, and registered signal type, the MT36KSF1G72PZ-1G4K1 is unmistakably a server memory module engineered for relentless data center workloads. In virtualized clusters, its ECC is not a luxury but a safeguard—it actively corrects single-bit errors and detects multi-bit corruption, preventing silent data corruption that could crash multiple tenant VMs or propagate flawed records into mission-critical databases. The registered buffer decouples the memory bus from the CPU, allowing dense dual-socket servers to populate all DIMM slots without signal degradation, so your hypervisor stack scales reliably. Meanwhile, the dual-rank x4 organization interleaves data streams across internal banks, delivering higher sustained bandwidth under the random, small-block access patterns typical of in-memory databases like Redis or SAP HANA. Every microsecond of latency matters there, and dual rank consistently outperforms single rank in mixed IO. Crucially, the 1.35V ultra-low operating voltage directly cuts power draw at the slot level—multiply that across a rack of 512 GB nodes, and you measurably reduce both energy costs and thermal stress on fan arrays, extending hardware service life in always-on environments. This is not generic memory; it is a purpose-built asset for workload consolidation where integrity, density, and efficiency converge.
These 8 GB 1.35V Registered ECC DIMMs (DDR3-1333 RDIMM) are unequivocally server-grade memory. The capacity planning below exploits their registered buffering, error correction, and low-voltage efficiency.
General Virtualization
Populate all memory channels evenly to maintain balanced NUMA performance. A typical dual‑CPU server using 12 of these 8 GB modules (96 GB total) comfortably hosts 20–30 virtual machines while delivering predictable latency. Always install identical DIMMs to preserve symmetrical interleaving and reliable ECC operation.
In‑Memory Database
Fill every available slot to maximize capacity—for instance, 24 × 8 GB (192 GB) in a dual‑socket platform. The dual‑rank x4 organization improves bank‑level parallelism, sustaining high transaction rates for Redis or SAP HANA. The 1.35 V low‑voltage supply further reduces power and cooling overhead in dense deployments.
High‑Performance Computing
For bandwidth‑sensitive workloads, install one DIMM per channel (1DPC) to run all modules at the full 1333 MHz with CL9 timings. Deploying 8 × 8 GB per socket (64 GB total) achieves consistent throughput and a 1T command rate, minimizing latency for MPI simulations and numerical analysis.
Rigorously tested, compatible with servers such as Dell PowerEdge R720, HP ProLiant DL380p Gen8, Lenovo ThinkServer RD630.
Q: Can I mix this MT36KSF1G72PZ-1G4K1 with other memory modules of different brands or speeds?
A: Mixing is not recommended in server environments. Different modules may disable ECC, cause instability, or downgrade speed. Always use identical RDIMMs to ensure data integrity and system reliability.
Q: Is this memory compatible with my server system?
A: This DDR3-1333 Registered ECC RDIMM works with Intel Xeon E5-2400/2600 v1/v2 and AMD Opteron 6300/4300 platforms. Please consult your motherboard's QVL list to confirm full compatibility.
Q: What is the recommended DIMM population order for optimal performance?
A: Install identical DIMMs per channel, starting with the farthest slot from the CPU. For dual-rank x4 RDIMMs, follow the server manual to balance memory across channels, maximizing throughput and ECC efficiency.
Q: Does this module support overclocking or XMP profiles?
A: No. Server Registered ECC memory adheres strictly to JEDEC timing at DDR3-1333 CL9. It does not support overclocking or XMP, as stability and error correction are critical for 24/7 operations.
Q: What warranty and typical failure rate can I expect?
A: This module carries a one-year warranty. As an enterprise-grade RDIMM built with stringent reliability standards, its expected annualized failure rate is below 0.5% under normal thermal conditions.
