This 128GB DDR4-2933 RDIMM with octal rank x4 organization and registered ECC is purpose-built for high-density server deployments, excelling in virtualization, in-memory databases, and workloads that demand uncompromising data integrity. The registered signal type stabilizes command and address buses under heavy multi-DIMM configurations, while 1.2V operation and CL21 latency balance power efficiency with reliable 2933MT/s throughput across enterprise platforms.
1. The 128GB capacity per module allows dense memory configurations that underpin massive virtualization farms, enabling thousands of containers or VMs on a single node without swapping.
2. ECC protection silently corrects single-bit errors in real time, preserving data integrity for financial ledgers and transactional databases that cannot tolerate corruption.
3. Registered signal buffering stabilizes the command bus across fully populated channels, letting operators scale to multi-terabyte footprints while maintaining consistent access latencies under load.
4. Octal Rank x4 organization maximizes rank interleaving efficiency, keeping memory pipelines saturated and delivering predictable performance during extreme consolidation of enterprise workloads.
5. 2933MT/s throughput provides the bandwidth headroom needed for concurrent analytics queries and in-memory caching, reducing response time for business intelligence dashboards.
The MTA144ASQ16G72LSZ-2S9E2TI is a 128GB DDR4-2933 registered ECC module built for server environments where data integrity, massive capacity, and sustained bandwidth are non-negotiable. Its four critical attributes—ECC, registered buffer, high density, and octal-rank architecture—address the real-world demands of virtualization clusters and in-memory databases. In a VMware farm, ECC corrects single-bit errors that can silently corrupt hypervisor memory, preventing cascading VM failures that disrupt business continuity. The register buffers commands and addresses, allowing stable operation at 128GB per DIMM so you can fill all slots and reach terabyte-scale memory without signal degradation. For an in-memory analytics platform like SAP HANA, the octal-rank design interleaves access across eight ranks, sustaining near-peak bandwidth even under heavy concurrency. This means faster query execution and real-time insights, while the 128GB footprint caches entire hot datasets in DRAM, slashing latency versus disk paging. It’s engineered to keep your critical workloads running reliably and at top speed.
Capacity Planning Guide for 128GB DDR4 RDIMM
This 128GB DDR4-2933 Registered ECC module (octal-rank, x4) is strictly an enterprise server component. Capacity planning must balance channel population, CPU memory controller limits, and octal-rank speed restrictions. Always consult platform guidelines, as fully loaded channels may force reduced clock speeds.
General Virtualization
Install identical DIMMs across all populated channels to maintain balanced performance. In a dual-socket server with eight channels, eight 128GB modules provide 1TB, comfortably hosting hundreds of VMs while preserving memory interleaving. Split capacity evenly between CPUs to minimize remote NUMA latency.
In-Memory Database
For Redis or SAP HANA, consistent latency is vital. Equip each channel with one 128GB DIMM; a six-channel system yields 768GB with uniform access. Avoid mixing ranks or capacities, as imbalanced configurations create bandwidth hotspots that degrade query response times.
High-Performance Computing
Maximize bandwidth by populating all channels symmetrically. In a 12-channel platform, twelve 128GB modules deliver 1.5TB and peak throughput for large simulation meshes. Verify the server’s support for octal-rank DIMMs at full speed—many designs require stepping down to 2666MT/s when fully populated.
Rigorously tested server memory. Compatible with Dell PowerEdge R760, HPE ProLiant DL380 Gen10, Lenovo ThinkSystem SR650, and more.
Q: Can I mix this MTA144ASQ16G72LSZ-2S9E2TI with other memory modules of different brands or speeds?
A: Mixing is strongly discouraged. ECC Registered DIMMs require identical specifications for reliable signaling. Mixing different speeds, ranks, or brands risks POST failures, stability issues, or silent data corruption in mission-critical server environments.
Q: Is this memory compatible with my system? (Intel/AMD server platforms)
A: It is designed for servers supporting DDR4-2933 Registered ECC RDIMMs, such as 2nd Gen Intel Xeon Scalable or AMD EPYC 7002 series. Always verify your motherboard or server vendor's qualified vendor list (QVL) for this specific part number.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server platform's memory population guidelines. Typically, populate identical DIMMs balanced across all memory channels, starting with the slots farthest from the CPU per channel, to maintain optimal interleaving and bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a server-grade Registered ECC RDIMM operating at JEDEC-standard DDR4-2933 with CL21 timings. It does not support overclocking or XMP, as absolute data integrity and long-term stability are prioritized over higher speeds.
Q: What warranty and typical failure rate can I expect?
A: This module carries a 1-year warranty. As enterprise-class memory built with rigorous screening and ECC technology, it exhibits a very low annualized failure rate, typically under 0.5% in properly cooled, compliant systems.
