Designed for entry-level servers and workstations, this 32GB DDR4-3200 UDIMM with ECC enhances data integrity for critical applications like virtualization, NAS, and memory-resident databases. Its dual rank x8 organization boosts bandwidth efficiency while the CL22 latency ensures responsive performance, and the unbuffered signal path reduces command-to-response time for reliable operation in single-socket platforms.
1. ECC protection silently corrects single-bit memory errors in real time, preserving data integrity for mission-critical enterprise workloads where even minor corruption is unacceptable.
2. 32 GB capacity delivers ample headroom for virtualized environments, allowing more VMs or containers to coexist without memory swapping and lag.
3. DDR4 technology provides a mature and validated platform foundation that ensures broad compatibility and rock-solid stability across server deployments.
4. 3200 MHz speed elevates memory bandwidth, accelerating database queries and in-memory analytics that depend on rapid data movement.
5. Dual Rank x8 organization leverages rank interleaving to boost effective throughput, keeping latency low under heavy concurrent access patterns.
The MTA18ASF4G72AZ-3G2 is a server-grade DDR4 UDIMM engineered for demanding enterprise environments, and its four core characteristics directly address the real pain points of IT infrastructure. ECC (Error Correcting Code) is non-negotiable in a virtualized cluster running multiple VMs on a hypervisor: a single bit flip in memory can silently corrupt guest data or crash an entire node overnight, but ECC detects and corrects these errors instantly, preserving data integrity and uptime. The generous 32 GB capacity, built on a dual-rank x8 design, lets you provision more virtual machines or run an in-memory database like Redis without constant swapping to slower storage. Dual rank further boosts performance by enabling bank interleaving, which increases effective bandwidth during concurrent access patterns—a typical scenario when dozens of web containers hammer the memory concurrently. The 3200 MT/s speed reduces latency in these heavy multi-threaded workloads, so real-time analytics queries return faster. Meanwhile, the 1.2 V low-voltage design helps reduce thermal load in dense server chassis, keeping cooling costs in check. Together, these features mean your microservices stay responsive under load, your database transactions remain accurate, and your server room runs more efficiently, which translates directly into higher service reliability and lower operational overhead.
Capacity Planning Guide for 32GB DDR4-3200 ECC UDIMM
This module is an unbuffered ECC DIMM designed for entry-level servers and workstations with UDIMM support. For reliable capacity planning, always install identical modules with matching part numbers to avoid mixing ranks or timings.
General Virtualization
Virtualization thrives on memory capacity and stability. Populate all four available DIMM slots with these 32GB dual-rank modules to reach the typical 128GB platform maximum, allowing numerous VMs to run comfortably. Full slot population also guarantees ECC error correction across every channel.
In-Memory Database
In-memory databases like Redis or SAP HANA demand large, low-latency footprints. Fill every channel with identical 32GB UDIMMs for a balanced 128GB capacity, which suits modest analytics and caching workloads. For larger datasets, understand that UDIMM platforms cap at this density and migrating to RDIMM-based servers becomes necessary.
High-Performance Computing (HPC)
HPC workloads prioritize memory bandwidth alongside integrity. Install a symmetric pair or quad of these dual-rank modules to enable dual-channel interleaving and sustain 3200MT/s throughput. Four identical 32GB sticks provide both the 128GB capacity and the balanced channel configuration essential for simulation and modeling codes that leverage ECC availability.
Rigorously tested, this server ECC UDIMM is compatible with Dell PowerEdge T140/T340, Lenovo ST50 V2, and Supermicro X12 boards.
Q: Can I mix this MTA18ASF4G72AZ-3G2 with other memory modules of different brands or speeds?
A: Mixing modules is not recommended in server environments. Different brands or speeds can cause signal integrity issues and system instability. For reliable operation, populate all slots with identical Micron ECC UDIMMs.
Q: Is this memory compatible with my system?
A: This 32GB DDR4-3200 ECC UDIMM is designed for single-socket servers and workstations based on Intel Xeon E-2300/E-2100 or AMD Ryzen PRO platforms that support unbuffered ECC memory. Always check your system's qualified vendor list.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server motherboard manual. As a general rule, populate channels symmetrically, placing this dual-rank module in the primary slot of each channel, often the slot furthest from the CPU, to maximize signal quality.
Q: Does this module support overclocking or XMP profiles?
A: No. This JEDEC-compliant server memory module does not support overclocking or XMP. It operates strictly at standard specifications to ensure maximum data integrity and 24/7 stability under mission-critical workloads.
Q: What warranty and typical failure rate can I expect?
A: It includes a one-year warranty. Micron server-grade modules exhibit an extremely low annualized failure rate, typically under 0.1%, delivering the enterprise-class reliability expected in always-on server environments.
