This 256GB DDR4-1600 Registered ECC CDIMM is engineered for enterprise servers and memory-intensive workloads such as virtualization and in-memory databases, where the octal-rank x4 configuration enables exceptional capacity density per channel. Its registered signal type and ECC error correction together ensure robust signal integrity and data reliability even in fully populated multi-DIMM configurations, while the CL11 latency maintains consistent access times under heavy load.
1. 256 GB capacity per module enables extreme virtualization density, letting a single server host hundreds of VMs without memory bottlenecks slowing down consolidation ratios.
2. ECC correction continuously scrubs single-bit errors, preserving data integrity for financial transactions and in-memory databases where any corruption is unacceptable.
3. Registered signal buffering stabilizes command and address lines across heavily loaded memory channels, making it possible to scale to multi-terabyte footprints without signal degradation.
4. Octal rank x4 organization interleaves eight independent access groups per DIMM, saturating the memory channel to sustain bandwidth-hungry enterprise analytics and real-time processing.
5. CL11 tight column access latency shrinks the gap between a cache miss and data delivery, giving latency-sensitive server applications like high-frequency trading a measurable responsiveness edge.
In a data center where every transaction must be absolutely trustworthy, the MTA152ALF16G72MZ-1G6B2B5 server memory module transforms how your infrastructure handles critical workloads. Its hardware ECC automatically detects and corrects single-bit errors caused by cosmic radiation or electrical noise, which means a financial database processing millions of transactions never silently corrupts a decimal value that could cascade into compliance failures. The registered interface buffers command and address signals, allowing a dense virtualization host to populate all channels with this 256 GB DIMM without compromising signal integrity—no unexpected hypervisor crashes when you overcommit memory for dozens of production VMs. That massive 256 GB capacity, built on an octal-rank x4 organization, delivers deep memory bandwidth through rank interleaving, so an in-memory analytics platform like SAP HANA can scan colossal tables with far lower latency. You get predictable, line-speed data access during simultaneous snapshot, replication, and query storms, eliminating the tail latency that erodes user trust in real-time dashboards. For clusters running virtualized MySQL or Redis pools, this single DIMM consolidates memory resources while the registered ECC backbone ensures your uptime SLAs stay intact.
General Virtualization
Deploy this 256 GB Registered ECC module in dual-socket hypervisors to maximize memory density per channel. A single module per populated channel keeps all memory channels active while leaving room for future expansion, ideal for hosting numerous moderate-size VMs. Configure identical modules across both sockets to maintain balanced NUMA access and ensure memory reliability under sustained multi-tenant workloads.
In-Memory Database
For large in-memory datasets, install one module per channel to reach 256 GB capacity without interleaving penalties, which helps maintain low latency (CL11) critical for real-time analytics. Use the Registered and ECC features to protect data integrity during constant read/write operations. When scaling, populate all channels with matching modules to achieve terabyte-scale capacity while preserving predictable Octal Rank performance.
High-Performance Computing
For memory-bandwidth-bound HPC jobs, balance capacity and bandwidth by placing identical 256 GB modules in every available memory channel across all nodes. The DDR4-1600 speed and Octal Rank design deliver steady throughput for parallel simulations; enabling ECC guards against silent data corruption in long-running compute tasks. Plan a homogeneous cluster memory configuration to simplify scheduler job placement and avoid node imbalance under sustained parallel I/O.
Server-grade DDR4 CDIMM rigorously tested for Cisco UCS (C220 M4, C240 M4, B200 M4).
Q: Can I mix this MTA152ALF16G72MZ-1G6B2B5 with other memory modules of different brands or speeds?
A: Mixing is strongly discouraged. This registered ECC CDIMM is designed for specific IBM Power servers. Different brands, ranks, or speeds can cause signal integrity issues, system instability, or boot failure.
Q: Is this memory compatible with my system?
A: It is engineered for enterprise IBM Power Systems using CDIMM technology, supporting POWER8/POWER9 platforms that require 276-pin DDR4-1600 registered ECC modules. Verify your server model's memory matrix for CDIMM compatibility.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your IBM Power system’s service manual. Typically, populate identical capacity CDIMMs in matched sets across memory risers, starting with the slots farthest from the processor, to maintain balanced memory interleaving and ECC coverage.
Q: Does this module support overclocking or XMP profiles?
A: No. As an enterprise-grade registered ECC CDIMM, it strictly adheres to JEDEC DDR4-1600 standards with CL11 latency. It does not support overclocking or XMP, ensuring maximum data integrity for mission-critical workloads.
Q: What warranty and typical failure rate can I expect?
A: This module carries a one-year warranty from the point of sale. Engineered with octal-rank x4 DRAM and robust ECC, it exhibits extremely low annualized failure rates, typically below 2% when operated within specified thermal and voltage limits.
