This unbuffered ECC UDIMM is tailored for entry-level server and professional workstation platforms, ensuring data integrity for critical workloads such as light virtualization and office productivity. Its single-rank x8 configuration with CL22 latency delivers stable, low-voltage 1.2 V operation at 3200 MT/s, balancing reliable error correction with efficient thermal performance.
1. ECC protection detects and corrects single-bit memory errors in real time, safeguarding transactional data integrity for always-on server workloads.
2. Sixteen gigabyte capacity per module allows dense memory configurations, letting virtualization hosts run more simultaneous VMs without immediate platform upgrades.
3. 3200 MT/s transfer speed elevates memory bandwidth to keep pace with modern multi-core server CPUs, reducing data bottlenecks during intense database queries.
4. Single Rank x8 organization puts less electrical load on the memory controller, improving signal integrity and enabling stable operation when all DIMM slots are populated.
5. 1.2V operating voltage cuts overall power draw and cooling demands inside rack enclosures, which lowers energy costs for deployments running numerous modules around the clock.
When you are running a small-office virtualization host or an in-memory database like Redis on a workstation, memory errors are not just numbers on a datasheet—they mean corrupted transactions, silent data loss, or an entire VM cluster failing over at 3 a.m. The MTA9ASF2G72AZ-3G2R is a 16GB DDR4-3200 UDIMM with true ECC, designed specifically for entry-level servers and professional workstations where data integrity is non-negotiable but a full RDIMM platform would be cost-prohibitive. Its unbuffered architecture keeps electrical latency low, so while ECC corrects single-bit upsets caused by background radiation, your memory-resident cache still responds in CL22 cycles—fast enough that a financial analytics dashboard renders without perceptible lag. In a virtualization scenario, the single-rank x8 organization ensures clean signal integrity when four DIMMs are populated, allowing you to assign consistent, predictable bandwidth to each guest machine instead of watching hypervisor performance degrade under multi-VM pressure. And because it operates at 1.2V, a 24/7 database node accumulates measurably lower thermal stress and power draw over years of continuous uptime, giving you stability that directly reduces TCO. This module translates those specs into reliability you can budget on.
Server Memory (ECC UDIMM) Identification
This DDR4-3200 module’s ECC, unbuffered, 288-pin UDIMM form factor identifies it as server-grade memory suited for entry-level servers and workstations using platforms like AMD Ryzen or Intel Xeon E series. The 16 GB single-rank x8 design balances error correction with moderate capacity, making it ideal for targeted capacity planning across three key workload scenarios.
General Virtualization
For virtualized environments hosting multiple light to medium VMs, populate all available channels with identical 16 GB modules to maximize memory bandwidth and headroom. A dual-socket server can start with four modules (64 GB) in a balanced configuration, scaling to 128 GB as VM density increases while keeping ECC protection active.
In-Memory Database
In-memory databases like Redis or SAP HANA demand large, contiguous memory pools. Use the maximum supported DIMMs per channel, ideally four to eight modules for 64–128 GB, ensuring all ranks are evenly distributed across memory controllers. Single-rank DIMMs reduce electrical loading, allowing higher sustained transfer rates crucial for real-time data processing.
High-Performance Computing (HPC)
HPC workloads benefit from filling all memory channels to reach peak theoretical bandwidth. Configure eight identical 16 GB ECC UDIMMs (128 GB total) across eight channels if the platform supports it, minimizing interleaving gaps. This aligned population eliminates bottlenecks for throughput-sensitive simulation and modeling codes while retaining error correction for long-running jobs.

Q: Can I mix this MTA9ASF2G72AZ-3G2R with other memory modules of different brands or speeds?
A: Mixing is not recommended. ECC UDIMMs should be identical in speed, rank, and timings to maintain data integrity. Different brands or speeds may force the system to downclock and disable ECC functionality.
Q: Is this memory compatible with my system?
A: This 288-pin DDR4 ECC UDIMM requires a platform supporting unbuffered ECC memory, such as Intel Xeon E-2100/2200 series with C246 chipset or AMD Ryzen PRO with B550/X570 boards. Verify your motherboard’s QVL.
Q: What is the recommended DIMM population order for optimal performance?
A: For dual-channel platforms, populate identical DIMMs in slots of the same channel (typically A2 and B2 on 4-slot boards). Consult your motherboard manual for exact population rules to maintain full ECC and dual-channel bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-compliant DDR4-3200 CL22 module. Server and workstation ECC UDIMMs do not support XMP or overclocking; they operate at standard default speeds to ensure data reliability and stability.
Q: What warranty and typical failure rate can I expect?
A: This Micron module includes a one-year warranty. ECC UDIMMs undergo rigorous testing and typically exhibit an annualized failure rate (AFR) well below 0.5% under proper environmental conditions.
