This 32GB DDR4-3200 RDIMM, with ECC and registered signaling, is purpose-built for server platforms running memory-intensive workloads such as virtualization and in-memory databases, where its Single Rank x4 configuration ensures optimal signal integrity and full-speed operation across all populated DIMM slots. The CL22 latency and ECC error correction deliver reliable data integrity under sustained load, making it an ideal choice for mission-critical enterprise environments.
1. A 32GB capacity per module allows dense memory configurations, maximizing the number of virtual machines or containers a server can host before requiring costly hardware expansion.
2. 3200 MHz speed translates to 25.6 GB/s of bandwidth per DIMM, accelerating in-memory databases and reducing transaction latency under heavy virtualization workloads.
3. ECC error correction constantly scrubs data in transit, eliminating silent bit-flip corruption that could otherwise cause crashes in financial or mission-critical enterprise applications.
4. The registered signal type buffers command and address lines, enabling these high-capacity modules to be deployed across all slots while preserving signal integrity in multi-socket servers.
5. A single rank x4 organization minimizes electrical loading on the memory channel, allowing fully populated servers to sustain maximum rated speed for stable, high-density virtual machine consolidation.
Based on its specifications, the MTA18ASF4G72AZ-3G2B1R is unmistakably a server-grade Registered DIMM. This 32GB DDR4-3200 module is engineered for environments where uptime and data integrity are absolute priorities, and its four core attributes translate directly into real-world reliability.
First, the registered signal type with a single-rank x4 organization provides a crucial stability advantage. In a densely populated virtualization cluster running dozens of VMs, unbuffered memory often suffers signal degradation as more sticks populate the channels. This RDIMM buffers command and address signals, maintaining clean communication even when all server slots are filled, which prevents random crashes during peak load. Second, ECC is non-negotiable for in-memory databases like Redis or SAP HANA. A single bit-flip caused by background radiation can silently corrupt a financial transaction or a customer record; ECC corrects these errors on the fly, safeguarding data accuracy. Third, the 3200 MHz data rate delivers the high bandwidth required when multiple VMs contend for memory, reducing latency spikes during concurrent analytics jobs. Fourth, the 32GB capacity coupled with 1.2V operation strikes a critical balance, allowing a single 1U server to host memory-hungry applications without exceeding thermal and power budgets. For a database administrator, this module means you can run more demanding workloads with full confidence that your data remains accurate and your services stay up.
General Virtualization
With its 32 GB RDIMM capacity and ECC, this module is ideal for dense VM hosting. Deploy six to eight modules per dual-socket server (192–256 GB total) to balance cost and density, populating channels evenly for optimal memory bandwidth under mixed workloads.
In-Memory Database
For Redis, SAP HANA, or Memcached, maximizing capacity and fault tolerance is key. Install a full set of twelve identical modules across all memory channels (384 GB per node) to saturate bandwidth while leveraging registered ECC to prevent in-flight data corruption during high-throughput caching.
High-Performance Computing (HPC)
Scaling for memory‑bound simulations requires balanced bandwidth. Configure four modules per socket (128 GB total) in a symmetric quad‑channel layout, matching CPU core counts. The combination of single‑rank x4 design and 3200 MT/s speed with CL22 latency optimizes transfer rates for iterative seismic or CFD workloads without throttling.
Rigorously tested DDR4 ECC RDIMM for servers, compatible with Dell PowerEdge R750, HPE DL380 Gen10 Plus, and Lenovo SR650 V2.
Q: Can I mix this MTA18ASF4G72AZ-3G2B1R with other memory modules of different brands or speeds?
A: It is strongly discouraged to mix this registered ECC RDIMM with different brands, speeds, or ranks. Mismatched DIMMs can impair signal integrity, force lower speeds, and lead to system instability in server platforms.
Q: Is this memory compatible with my server system?
A: This DDR4-3200 ECC RDIMM is broadly compatible with platforms supporting 288-pin Registered DIMMs, such as Intel Xeon Scalable and AMD EPYC 7002/7003 series. Please verify your server board’s Qualified Vendor List for confirmation.
Q: What is the recommended DIMM population order for optimal performance?
A: For optimal performance, populate identical DIMMs evenly across all memory channels. Typically, install one DIMM per channel first, following the server’s manual for slot sequence. This maximizes bandwidth and maintains balanced load.
Q: Does this module support overclocking or XMP profiles?
A: No, this JEDEC-compliant server RDIMM does not support overclocking or XMP profiles. It is designed to operate reliably at the fixed 3200 MT/s speed with 22-22-22 timing, prioritizing data integrity and stability.
Q: What warranty and typical failure rate can I expect?
A: This module includes a one-year warranty. Built with rigorously tested, server-grade components, it achieves an extremely low annualized failure rate well below industry averages, ensuring dependable 24/7 operation in demanding environments.
