This UDIMM module is a standard DDR4-2133 desktop memory kit, ideally suited for mainstream productivity builds, gaming rigs, and general content-creation workloads where stable JEDEC-compliant operation is prioritized. Its dual-rank x8 organization enhances memory interleaving and bandwidth utilization at the default 1.2V, while the CL15 latency ensures responsive performance without the need for overclocking.
1. A 16GB capacity ensures seamless multitasking between demanding applications like video editors and browser-heavy research, keeping the creative workflow fluid without disk caching.
2. The Dual Rank x8 organization interleaves memory banks to boost effective bandwidth, which noticeably accelerates scene rendering and large asset transfers in content creation suites.
3. CL15 timing delivers lower command latency, giving competitive gamers faster system reactions and more consistent frame pacing during intense multiplayer matches.
4. Operating at the JEDEC-standard 2133 MT/s speed, the module offers guaranteed plug-and-play stability across mainstream desktop platforms, ideal for OEM upgrades and reliable office productivity.
5. The 1.2V DDR4 supply voltage reduces heat dissipation inside the chassis, helping tower coolers maintain quiet acoustics and steady thermals during extended gaming sessions.
The M378A2K43BB1-CPB is a desktop DDR4 UDIMM whose design directly tackles the real frustrations of gamers and content creators. The 16GB capacity eliminates the stutter-inducing memory swapping that occurs when juggling a demanding AAA title, background voice chat, and streaming software. Its dual-rank x8 architecture cleverly interleaves data access, significantly boosting bandwidth during 4K video rendering in Premiere Pro or DaVinci Resolve, where massive frame caches must flow without bottlenecking your timeline preview. The 2133MHz frequency paired with a CAS latency of 15 ensures tight command execution; in competitive gaming, this lower absolute latency translates to reduced input-to-display lag and more consistent frame pacing during frantic firefights. Additionally, the 1.2V low-power design and Non-ECC, Unbuffered nature deliver plug-and-play stability across mainstream motherboards and keep heat emission minimal. For an overnight rendering session, this thermal efficiency prevents silent throttling, ensuring your project finishes on schedule with every frame intact.
Gaming Build
For a responsive gaming rig, a dual-channel configuration is essential to minimize micro-stutter and boost frame rates. A 2×8 GB kit leveraging these 16 GB UDIMMs provides 32 GB of headroom for modern titles and background tasks, while a single kit of two matched modules ensures stable XMP-free operation at DDR4-2133 with a CL15 latency you can trust.
Content Creation
Video editing and 3D rendering thrive on capacity, and populating four slots with these Dual Rank x8 16 GB modules yields 64 GB of affordable, high-density memory. The dual-rank design slightly improves per-channel bandwidth utilization, helping timeline scrubbing and viewport rendering feel fluid even without extreme frequencies.
General Productivity
Balancing cost and responsiveness, a 2×16 GB setup using these 1.2 V UDIMMs delivers 32 GB of smooth multitasking for office suites, browser tabs, and light content work. The low operating voltage and unbuffered, non-ECC nature keep both thermals and budget in check while sidestepping complexity that typical home-office users never need.
Rigorously tested, this desktop memory is compatible with systems like Dell OptiPlex 7050 and HP EliteDesk 800 G3.
Q: Can I mix this M378A2K43BB1-CPB with other memory modules of different brands or speeds?
A: We strongly advise against mixing. Mismatched speeds or timings force all modules down to the slowest common spec, often causing instability. For reliable 24/7 operation, install identical matched kits.
Q: Is this memory compatible with my system?
A: This DDR4-2133 UDIMM is compatible with Intel 100/200 series and AMD 300 series chipsets. Always verify your motherboard's QVL list and ensure it supports 16GB Dual Rank x8 modules.
Q: What is the recommended DIMM population order for optimal performance?
A: For dual-channel motherboards, populate identical modules in alternating slots (typically A2 and B2 first). This enables dual-channel mode for doubled memory bandwidth. Refer to your manual.
Q: Does this module support overclocking or XMP profiles?
A: No. This is a JEDEC-standard DDR4-2133 CL15 module running at 1.2V. It does not feature XMP profiles and is not designed for overclocking.
Q: What warranty and typical failure rate can I expect?
A: This module comes with a 1-year warranty. It uses Samsung components with very low failure rates (<0.5% AFR), ensuring excellent long-term reliability.
