This SoDIMM is a standard non-ECC unbuffered DDR4 notebook memory module, ideally suited for upgrading mainstream laptops and mobile workstations where low power consumption and straightforward plug-and-play compatibility are essential. Its single-rank x16 organization minimizes electrical loading on the memory controller, enabling stable 2666 MT/s operation at the tight CL19 latency without requiring any manual tuning.
1. SoDIMM form factor guarantees hassle-free plug-and-play compatibility with a vast range of ultra-thin laptops and compact mini-PCs, eliminating guesswork during upgrades.
2. 4GB capacity provides enough working memory for smooth web conferencing, document editing, and media streaming, extending the useful life of entry-level notebooks.
3. DDR4 technology lowers the operating voltage significantly, which translates directly into cooler, quieter operation and longer untethered runtime on battery power.
4. 2666 MT/s transfer rate keeps everyday applications launching instantly and multiple tabs scrolling without lag, boosting productivity for mobile professionals between meetings.
5. CL19 latency fine-tunes command-to-data timing to deliver responsive clicks and window switches while preserving the energy efficiency essential for slim, passively cooled laptops.
The Micron MTA4ATF51264HZ-2G6 is a notebook DDR4 SODIMM whose four defining characteristics directly resolve the real frustrations of mobile computing. Its 260-pin small-outline form factor guarantees drop-in compatibility across ultrabooks and portable workstations alike, turning a potential service headache into a simple, tool-free upgrade you can perform in minutes. Operating at a true 1.2V, the DDR4-2666 speed delivers a tangible boost in bandwidth while dramatically extending battery runtime. For a field engineer running CAD overlays on a rugged laptop, that means critical applications stay responsive through a full shift without hunting for an outlet. The 4 GB capacity and single-rank x16 organization let you populate a second slot for dual-channel performance, banishing the stuttering lag that plagues heavy multitasking between browser tabs and office suites. Because this module is unbuffered and non-ECC, it draws minimal power and requires no driver or BIOS tweaking, offering true plug-and-play simplicity. For a student upgrading a thin-and-light laptop before a semester of research, these attributes translate into a seamless, efficient upgrade that keeps work flowing and the charger in the bag.
Laptop Upgrade
For most older notebooks with a single 4 GB module, adding a second identical 4 GB DDR4‑2666 SO‑DIMM brings total capacity to 8 GB in dual‑channel mode, significantly improving multitasking responsiveness. If the system supports 16 GB, replace the existing module with two 8 GB sticks instead of keeping the 4 GB part, as mismatched capacities may disable symmetric dual‑channel operation.
Mobile Workstation
Professional workloads such as CAD, 3D rendering, or large data analysis demand maximum capacity. Populate both SO‑DIMM slots with the highest supported density—typically two 16 GB or two 32 GB modules—to reach 32 GB or 64 GB. Although the 4 GB module is not useful here, ensure all installed sticks have identical rank and timing to maintain stability under sustained load.
Ultrabook Power Saving
This 4 GB single‑rank module operates at standard 1.2 V, which is already efficient, but ultrabooks seeking extended battery life should source low‑voltage (1.05 V) alternatives where supported. If upgrading from soldered memory, pair the onboard capacity with a matching SO‑DIMM to preserve dual‑channel bandwidth without increasing power overhead. Minimizing rank count per channel also helps reduce idle power draw.
This 4GB DDR4-2666 non-ECC unbuffered SoDIMM is rigorously tested and compatible with laptops like Dell Latitude 5400, HP EliteBook 840 G6, and Lenovo ThinkPad T490.
Q: Can I mix this MTA4ATF51264HZ-2G6 with other memory modules of different brands or speeds?
A: Mixing is possible but not recommended. The system will default to the slowest module's speed and timing, potentially causing instability. For reliable performance, use identical modules.
Q: Is this memory compatible with my laptop?
A: This is a DDR4 SO-DIMM for laptops. Verify your laptop supports DDR4-2666 non-ECC unbuffered memory, up to 4GB per slot, and has a 260-pin interface. Check your model's specifications.
Q: What is the recommended DIMM population order for optimal performance?
A: For dual-channel capable laptops, install this single-rank module as a matched pair in symmetric slots. Using just one will operate in single-channel mode, halving potential bandwidth.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a standard JEDEC-compliant DDR4-2666 CL19 module. It does not support XMP or overclocking and operates only at its programmed speed and timings for stability.
Q: What warranty and typical failure rate can I expect?
A: It includes a one-year warranty. As a Micron DDR4 module running at JEDEC standard, its annualized failure rate is extremely low, typically under 0.5%, ensuring high reliability for standard use.
