This unbuffered ECC DDR4-2133 module, organized as dual-rank x8 with a CAS latency of 15, is purpose-built for entry-level servers and workstations that demand data integrity without the cost of registered memory. Its ECC error correction and dual-rank interleaving deliver stable, reliable performance ideal for light virtualization, file serving, and mission-critical productivity workloads.
1. ECC error correction silently detects and fixes single-bit memory errors, preserving data integrity for financial transactions or virtualization hosts where even a flipped bit can corrupt critical workloads.
2. 8 GB capacity suits lightweight server roles like edge caching, DNS, or branch-office domain controllers, balancing sufficient memory density with lower power and cost per node.
3. DDR4-2133 standard speed delivers a predictable, stable bandwidth envelope essential for always-on services that prioritize uptime over peak benchmark figures.
4. Dual Rank x8 organization interleaves memory accesses across internal banks, increasing effective throughput and reducing latency for multi-tenant container environments on a single socket.
5. Unbuffered UDIMM design removes the register clock latency, offering lower idle power and a more affordable bill-of-materials for small-business NAS or firewall appliances without sacrificing ECC protection.
The Micron MTA18ASF1G72AZ-2G1B1 is an 8GB DDR4-2133 ECC Unbuffered DIMM purpose-built for entry-level servers and professional workstations, where data integrity and consistent performance directly translate into business continuity. Its ECC engine is the first line of defense against silent data corruption from background radiation or aging cells; for a small business running a virtualized domain controller and a file server on the same host, this means a single-bit error never cascades into a corrupted invoice database or a downed authentication service. The dual-rank x8 organization then steps up for in-memory workloads like Redis caching, where alternating rank access keeps the data pipeline saturated and query response times predictably low during transaction peaks. While many server modules prioritize capacity over response speed, the unbuffered signal path here eliminates register clocking delays so that latency-sensitive applications, such as a high-frequency trading journal or a live customer interaction log, see microseconds shaved off every record commit. Backed by a low 1.2V operating voltage, the module also reduces power draw and cooling burden inside compact 1U chassis, allowing your IT team to run denser, more reliable services without re-engineering the thermal envelope.
As a server ECC UDIMM, this 8 GB DDR4‑2133 module targets single‑socket servers and workstations that require data integrity. Capacity planning recommendations for typical workloads:
General Virtualization
Install identical modules in channel‑matched pairs to enable dual‑ or quad‑channel interleaving. Starting with four sticks (32 GB) supports 8‑12 moderate VMs comfortably, while an eight‑slot board can be fully populated to 64 GB for higher VM density. ECC protection is essential for multi‑tenant stability.
In‑Memory Database
Maximise footprint by filling every DIMM slot — eight modules deliver 64 GB of reliable, low‑latency storage. The dual‑rank design increases bank‑level parallelism, boosting transaction rates for caching engines. Always balance channels symmetrically so that memory access remains uniform under heavy Redis or memcached workloads.
High‑Performance Computing
Prioritise bandwidth: place one 8 GB module per memory channel (e.g., four modules for quad‑channel) to sustain full 2133 MT/s and peak interleaving. The resulting 32 GB meets the capacity needs of many MPI simulations while minimising power draw and guaranteeing deterministic ECC behaviour for tightly coupled jobs.

Q: Can I mix this MTA18ASF1G72AZ-2G1B1 with other memory modules of different brands or speeds?
A: Mixing is not recommended for server environments. Even identical specs from different brands or speeds may cause signal integrity issues and system instability, potentially leading to memory errors under load.
Q: Is this memory compatible with my system?
A: This ECC UDIMM is designed for entry-level servers and workstations. Verify your board supports DDR4-2133 ECC Unbuffered memory on platforms like Intel Xeon E3/E-2100/2200 series or select AMD Ryzen PRO processors.
Q: What is the recommended DIMM population order for optimal performance?
A: Consult your motherboard manual. Generally, install this dual-rank module in the primary slot of each memory channel first, populating identical-colored slots to enable interleaved ECC and maximize throughput.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-compliant server-grade module operating at standard DDR4-2133. It does not support XMP or overclocking; reliability and ECC integrity are prioritized over frequency adjustments.
Q: What warranty and typical failure rate can I expect?
A: It includes a one-year warranty. As an enterprise-class ECC module built with rigorously screened components, it carries an extremely low annualized failure rate, ensuring high reliability for critical workloads.
