This DDR4-2400 UDIMM with ECC is engineered for entry-level servers and workstations where data integrity is critical, making it ideal for light virtualization, file services, and memory-sensitive applications that demand reliable uptime. Its dual-rank x8 organization enhances interleaving efficiency for improved bandwidth, while unbuffered signaling and CL17 latency keep access times low to optimize response in single-socket platforms.
1. ECC protection actively detects and corrects single-bit errors, preserving data integrity for financial transactions or scientific computations where even silent memory corruption is unacceptable.
2. Dual Rank x8 organization enables rank interleaving, sustaining higher command rates and throughput that reduce latency spikes in virtualized database servers.
3. The 8 GB capacity provides just enough memory footprint to run lightweight hypervisors and containerized microservices without wasteful idle power draw.
4. Unbuffered signaling eliminates register delays, delivering lower access latency that benefits high-frequency trading or real-time caching appliances in compact server nodes.
5. Operating at 2400 MT/s, the DDR4 interface balances bandwidth and energy efficiency, maintaining steady responsiveness for moderate-load web serving or file sharing workloads.
The MTA18ASF1G72AZ-2G3B1 is an 8GB DDR4-2400 UDIMM with ECC, clearly positioned for entry-level servers and workstations where data integrity and responsiveness directly impact business outcomes. The ECC functionality is your first line of defense against single-bit memory errors caused by cosmic radiation or electrical noise; in a virtualized cluster hosting multiple VMs, an undetected bit flip can silently corrupt a guest operating system or a financial transaction, leading to crashes or incorrect results. This module prevents that silently, ensuring every calculation remains trustworthy.
The dual-rank x8 organization maximizes bandwidth through rank interleaving, allowing the memory controller to access one rank while the other refreshes or completes a prior command. For an in-memory database like Redis, this translates into higher sustained throughput under heavy read/write workloads, reducing latency spikes when serving thousands of concurrent queries. The unbuffered design paired with a 1.2V operating voltage delivers lower power consumption and reduced heat generation compared to registered alternatives, which is critical in compact server chassis where thermal headroom is limited. Meanwhile, the CL17 latency and 2400MHz speed fit perfectly into cost-conscious platforms running Hyper-V or VMware on single-socket motherboards, where every watt and every clock cycle must be optimized. You get reliable, low-overhead memory that shields your virtualization stack from silent data corruption while keeping energy bills in check and performance consistent under real, sustained loads.
General Virtualization
For moderate VM densities, deploy the modules in matched pairs or sets of four to enable dual- or quad-channel interleaving. A 32GB (4×8GB) configuration per host efficiently supports a mix of light services and ensures ECC reliability. Balance DIMMs across CPU memory channels to prevent bandwidth bottlenecks.
In-Memory Database
In-memory databases require maximum capacity and error protection. Fill every available slot with identical 8GB ECC UDIMMs, keeping each processor’s memory channels symmetric. While per-module capacity is modest, populating all slots (e.g., 16×8GB) yields 128GB of protected memory; verify platform UDIMM limits to avoid instability.
High-Performance Computing
HPC workloads demand high bandwidth. Populate each memory channel uniformly—ideally one 8GB module per channel—to achieve full sustained throughput. A fully populated 8-channel system delivers 64GB at peak speed. Avoid mixing different capacities or ranks to maintain low, consistent CAS latency across nodes.
Validated for server use, rigorously tested. Compatible with Dell PowerEdge T40, T140, R240, HPE ProLiant ML30 Gen10.
Q: Can I mix this MTA18ASF1G72AZ-2G3B1 with other memory modules of different brands or speeds?
A: Mixing is not advised for server environments. It may force the memory controller to run at the lowest common speed and compromise ECC stability. Use identical modules for guaranteed reliability.
Q: Is this memory compatible with my system?
A: This 288-pin DDR4-2400 ECC UDIMM is designed for Intel Xeon E3-1200 v6/v5 and select AMD Ryzen PRO platforms. Confirm your motherboard explicitly supports 8GB Unbuffered ECC DIMMs before installation.
Q: What is the recommended DIMM population order for optimal performance?
A: Follow your server board manual. Typically, populate identical modules in channel A slots first, then channel B, to enable dual-channel interleaving. Dual-rank DIMMs should be balanced across channels.
Q: Does this module support overclocking or XMP profiles?
A: No. As a JEDEC-compliant ECC UDIMM, it runs at a fixed 2400MHz with CL17 timings. Overclocking and XMP are not supported to maintain data integrity required in server workloads.
Q: What warranty and typical failure rate can I expect?
A: It includes a 1-year warranty. Enterprise UDIMMs like this typically demonstrate an annualized failure rate (AFR) below 0.5% under specified environmental conditions, reflecting high operational reliability.
