This 16GB DDR5-4800 SODIMM integrates ECC error correction into an unbuffered, single-rank x8 design, making it ideal for mobile workstations and professional laptops where data integrity, low 1.1V power draw, and drop-in compatibility are essential. While the low-voltage operation and CL40 latency deliver efficient thermal performance, the ECC engine reliably guards against single-bit memory errors during precision workloads like on-site CAD, data analysis, or scientific computing.
1. The SoDIMM form factor with a compact 262-pin design allows tool-free drop-in installation, enabling mobile workstation users to upgrade memory in seconds without removing the entire chassis.
2. A 16-gigabyte capacity comfortably holds large virtual instruments, dense engineering datasets, and multiple concurrent containers, keeping complex on-the-go workflows responsive without swapping to storage.
3. On-die ECC silently corrects single-bit memory errors in real time, preserving calculation integrity during long-running renders, financial models, or scientific simulations when a reboot would cost hours of progress.
4. Operating at just 1.1 volts, the DDR5 supply voltage draws less power per transfer, directly reducing battery drain and fan noise so a high-performance laptop stays cooler and quieter under sustained load.
5. The 4800 MT/s transfer rate nearly doubles the bandwidth of previous-generation modules, slashing export times for 4K video edits and making real-time previews of large 3D assemblies feel fluid rather than stuttery.
The M426R2GA3BB0-CQKOL is a 16GB DDR5 SODIMM, purpose-built for modern notebooks. Its ECC error correction is the silent guardian for your mobile workstation: when you render complex 3D models or crunch datasets on the go, single-bit memory errors from cosmic radiation or electrical noise can corrupt results without warning. ECC detects and corrects these faults in real time, meaning your structural simulation or financial model remains flawless, even during an overnight hotel-room compute session. For ultrabook upgraders, the 1.1V operating voltage directly extends battery life—every watt saved translates into more runway during cross-country flights. The 4800MT/s speed at CL40 delivers responsive multitasking, so switching between a massive Excel pivot table and a video conference feels seamless. Its standard 262-pin SODIMM form factor also guarantees a tool-less, five-minute installation into most thin-and-light laptops, turning a sluggish system into a dependable, all-day performer without sacrificing reliability or portability.
Laptop Upgrade
Upgrade a single 8 GB SODIMM to this 16 GB DDR5-4800 ECC module to double capacity and enable smoother multitasking. Installing two identical modules unlocks dual-channel bandwidth, which noticeably improves integrated graphics performance and application responsiveness. Always confirm that your laptop supports ECC unbuffered SODIMMs before purchasing.
Mobile Workstation
For CAD, simulation, and in-memory data analysis, install two or four of these 16 GB ECC SODIMMs. A dual-module configuration delivers 32 GB, while a quad-slot mobile workstation can reach 64 GB of reliable, error-correcting memory at 4800 MT/s. ECC protection is critical when stability during prolonged renders, scientific computations, or financial modeling cannot be compromised.
Ultrabook Power Saving
The native 1.1 V DDR5 voltage and single-rank x8 design dramatically reduce power consumption, helping ultraportables achieve longer battery life. The unbuffered, single-rank organization further minimizes signal loading, trimming both active and standby power. A single 16 GB module strikes an ideal balance between capacity and energy efficiency for office suites, web browsing, and video streaming, all while fitting the slimmest chassis.
Rigorously tested, this 16GB DDR5 ECC Unbuffered SODIMM fits workstations like Dell Precision 7770, Lenovo ThinkPad P16, HP ZBook Fury G9.
Q: Can I mix this M426R2GA3BB0-CQKOL with other memory modules of different brands or speeds?
A: Mixing is strongly discouraged. ECC unbuffered SO-DIMMs require identical ranks, timings, and voltage to ensure stable operation. Dissimilar modules may force the system to disable ECC or fall back to non-optimized speeds, risking data integrity.
Q: Is this memory compatible with my system?
A: Compatibility requires a mobile workstation or laptop with a DDR5 SO-DIMM slot and explicit ECC support, typically on Intel Core or AMD Ryzen PRO platforms. Verify your model's specifications for 262-pin DDR5-4800 ECC unbuffered memory support.
Q: What is the recommended DIMM population order for optimal performance?
A: For single module installation, use the primary slot (often labeled 'DIMM1'). For dual-channel operation, populate both sockets with identical ECC modules to enable symmetric bandwidth. Refer to your system's service manual for exact slot numbering.
Q: Does this module support overclocking or XMP profiles?
A: No. This JEDEC-standard DDR5-4800 ECC SO-DIMM runs at its native frequency and does not house XMP profiles. Overclocking is not supported; the module is engineered for sustained reliability under error-corrected, stock parameters.
Q: What warranty and typical failure rate can I expect?
A: This module carries a 1-year warranty. Typical annualized failure rate (AFR) for enterprise-grade DDR5 ECC modules is well below 0.5% under specified environmental conditions, reflecting rigorous screening and testing.
