This 64 GB DDR4-2933 Registered ECC RDIMM, with a Quad Rank x4 organization, delivers the high-density memory capacity and signal integrity essential for demanding server environments. Its ECC protection and Registered clock driver ensure data reliability under heavy virtualization and in-memory database workloads, while the 2933 MT/s speed and CL21 latency provide a balanced performance profile for scalable enterprise platforms.
1. Error-correcting code protection eliminates single-bit memory errors, preserving data integrity for mission-critical enterprise databases and financial transactions.
2. Registered signal buffering stabilizes high-capacity memory configurations, enabling reliable operation across densely populated server nodes.
3. A 64GB capacity per module maximizes memory density in each server chassis, supporting expansive virtual machine fleets without sacrificing performance.
4. Quad Rank x4 organization packs more memory banks onto a single module, keeping data pipelines full during massive in-memory analytics workloads.
5. 2933MHz speed elevates memory bandwidth, accelerating parallel processing in virtualized environments and reducing latency for real-time data services.
The Micron MTA72ASS8G72LZ-2G9D3TI is a 64GB DDR4-2933 Registered DIMM built specifically for demanding server environments, and its four defining characteristics translate directly into measurable uptime and performance for your infrastructure. First, ECC error correction continuously detects and corrects single-bit memory errors, a critical safeguard in virtualized clusters where a silent bit flip in one guest could corrupt transactional data or crash an entire hypervisor host without warning. Second, the registered signal buffer stabilizes command and address lines across the quad-rank, high-density design, enabling you to populate all channels at full capacity without signal degradation—something unbuffered modules simply cannot sustain in a server with 24 or more DIMM slots. Third, 64GB of capacity on a single module, enabled by that quad-rank x4 organization, maximizes memory density per socket, directly increasing virtual machine density in a VMware or Nutanix cluster and giving you more headroom to consolidate workloads without adding servers. Fourth, the 2933MT/s speed and 64-bit ECC data path deliver 23.4GB/s of bandwidth per channel, which becomes the real-world accelerator for in-memory databases like SAP HANA or Redis. Every microsecond saved on large key-value lookups or analytical joins translates into faster decision-making for your business, while the combination of ECC and registered buffering ensures those accelerated queries return the right answers, every time.
General Virtualization
For a typical dual-socket virtualization host, install six or eight of these 64 GB RDIMMs evenly across the memory channels of each CPU to reach 384–512 GB total capacity while preserving balanced memory bandwidth. Populate identical DIMMs per channel and leave one DIMM slot per channel empty if possible, allowing future expansion without sacrificing NUMA locality.
In-Memory Database
Maximize capacity per server by fully populating all 12 or 16 DIMM slots with these quad-rank 64 GB modules, delivering 768 GB to 1 TB of RAM in a two-socket system. Because large in-memory datasets prioritize capacity over peak bandwidth, the slight frequency drop caused by quad-rank loading is an acceptable trade-off for applications like Redis or SAP HANA.
High-Performance Computing (HPC)
Achieve maximum memory bandwidth by installing one DIMM per channel—six or eight modules per CPU—giving 384–512 GB per node at the module’s full 2933 MT/s speed. This one-DIMM-per-channel (1DPC) configuration minimizes rank contention and ensures the sustained throughput required for memory-bound simulations and computational fluid dynamics workloads.
Validated and rigorously tested for Dell PowerEdge R760, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR650, and compatible servers.
Q: Can I mix this MTA72ASS8G72LZ-2G9D3TI with other memory modules of different brands or speeds?
A: Mixing RDIMMs of different brands or speeds is strongly discouraged. It can cause timing conflicts, signal integrity issues, and ECC errors, potentially compromising server stability. For mission-critical systems, always use identical, validated modules.
Q: Is this memory compatible with my server? I use an Intel Xeon Scalable Gen 2 platform.
A: Yes, this 64GB DDR4-2933 RDIMM is compatible with Intel Xeon Scalable (2nd Gen) and AMD EPYC platforms that support 2933MT/s ECC Registered memory. Confirm your board supports quad-rank x4 RDIMMs via the QVL.
Q: What is the recommended DIMM population order for optimal performance with this quad-rank module?
A: Follow your server motherboard’s memory population guide. Typically, populate identical quad-rank RDIMMs starting with the first slot in each memory channel. Incorrect order can drop speed or limit capacity; consult the manual for balanced configurations.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-compliant server RDIMM running at DDR4-2933 CL21. It does not support XMP or overclocking, as it is engineered for maximum data integrity and 24/7 stability in enterprise environments.
Q: What warranty and typical failure rate can I expect?
A: It includes a 1-year warranty. High-quality server RDIMMs like this exhibit an AFR typically below 0.5%. We replace any module that fails due to manufacturing defects within the coverage period.
