This is a notebook memory module, specifically a 16GB DDR4-2133 SoDIMM designed for upgrading mobile workstations and high-performance laptops where low power draw and drop-in compatibility are critical. Its dual-rank x8 organization improves memory bandwidth utilization under multi-tasking workloads, while the unbuffered signal type and CL15 latency ensure responsive, stable performance in thermally constrained chassis.
1. The 16GB capacity enables effortless multitasking and smooth productivity workflows, allowing business users to keep numerous browser tabs, documents, and communication apps open simultaneously without slowdowns on a compact ultrabook.
2. The SO-DIMM form factor ensures a straightforward drop-in upgrade path, letting mainstream laptop owners instantly boost system responsiveness without hunting for obscure proprietary modules.
3. The unbuffered signal type minimizes power draw and thermal output, a critical advantage for thin-and-light notebooks where every watt saved extends battery runtime during mobile presentations.
4. The 2133MT/s transfer rate delivers snappy everyday application launches and consistent performance in office suites, matching the balanced efficiency profile of modern energy-conscious laptop platforms.
5. A CAS latency of CL15 keeps command response tight, reducing perceptible lag when navigating complex spreadsheets or web-based collaboration tools, which translates directly into a more fluid user experience over long work sessions.
The M474A2K43BB1-CPBQ is a 16GB DDR4 SO-DIMM purpose-built for notebooks, and its four core attributes translate directly into a better mobile experience. The Unbuffered architecture strips out register components, cutting latency and power draw; paired with DDR4’s native 1.2V operation, this noticeably extends battery endurance during long flights or back-to-back meetings where every watt matters. Its dual-rank x8 organization keeps a mobile workstation responsive under punishing workloads—imagine manipulating a dense 3D assembly in CAD while hosting a local virtual machine; the interleaved ranks sustain higher bandwidth and prevent the micro-stutter that stalls productivity. For the growing number of professionals upgrading slim ultrabooks, the standard 260-pin SODIMM form factor and conservative DDR4-2133 CL15 profile remove all guesswork. There is no BIOS tuning, no compatibility lottery, just a precise physical fit and rock-steady signal integrity right after installation. You gain the capacity to handle heavy data analysis or memory-greedy presentation decks without sacrificing mobility, making this module a decisive upgrade that balances performance, reliability, and runtime in the real world.
Laptop Upgrade
For users with a single 16GB SoDIMM installed, adding a second identical module enables dual-channel mode, doubling memory bandwidth and improving integrated graphics performance. If your system supports two slots, swapping a single 16GB module for a matched pair of 16GB DDR4-2133 SoDIMMs delivers 32GB total without sacrificing dual-channel benefits.
Mobile Workstation
Professional workloads like CAD, 3D rendering, and large dataset analysis thrive on maximum capacity. Populate both slots with 16GB dual-rank x8 SoDIMMs to reach 32GB, ensuring smooth multitasking under memory-intensive applications. For newer laptops supporting 64GB via two 32GB modules, consider upgrading to higher-capacity kits while maintaining the same DDR4-2133 specification if the platform dictates.
Ultrabook Power Saving
In thin-and-light designs where battery life is critical, this standard-voltage DDR4-2133 module trades some efficiency for broad compatibility. When replacing soldered or single-slot configurations, choose an identical 16GB SoDIMM to preserve dual-channel operation, which can reduce memory controller power draw. For maximum runtime, consider a low-voltage DDR4L variant if your ultrabook’s chipset supports it, as the lower operating voltage directly extends battery endurance.
Rigorously tested, compatible with laptops: Dell Latitude 5490, Lenovo ThinkPad T480, HP EliteBook 840 G5.
Q: Can I mix this M474A2K43BB1-CPBQ with other memory modules of different brands or speeds?
A: Mixing is possible but not recommended. The system will downclock all modules to the slowest common JEDEC profile, potentially causing instability. Identical modules ensure validated compatibility and reliable dual-channel operation.
Q: Is this memory compatible with my system? I have a Dell Latitude 7480.
A: This DDR4-2133 SO-DIMM requires a notebook with DDR4 support and a 260-pin slot. Your Latitude 7480 officially supports DDR4-2133; verify CPU/chipset generation (6th/7th Gen Intel Core) and a 16GB-per-slot limit.
Q: What is the recommended DIMM population order for optimal performance?
A: For dual-channel notebooks with two slots, populate both with identical modules. If only one module, install in the primary slot (often marked 'DIMM A' or slot 0) per your service manual to avoid BIOS errors.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-compliant DDR4-2133 CL15 module without XMP. It operates at fixed standard timings. Most notebook BIOS firmware does not expose memory overclocking controls, so only the standard SPD profile is used.
Q: What warranty and typical failure rate can I expect?
A: It includes a 1-year warranty. Enterprise-grade modules like this Samsung unit exhibit an annualized failure rate (AFR) typically below 0.5% under normal operating conditions, ensuring long-term reliability.
