The Samsung M378A2K43EB1-CWE DDR4 UDIMM Memory

The category of DDR4 desktop memory modules includes high-performance components designed to improve the speed, stability, and multitasking ability of modern personal computers. Within this category, the M378A2K43EB1-CWE 16GB (1x16GB) 3200MHz PC4-25600 CL22 Non-ECC Unbuffered Dual Rank x8 1.2V DDR4 SDRAM 288-pin UDIMM Memory Module represents a professional-grade solution for users who want dependable performance for daily computing, business workstations, gaming systems, and content creation PCs.

This category focuses on unbuffered DDR4 UDIMM memory, which is commonly used in consumer and professional desktop systems. Unlike server-grade modules, these memory sticks are optimized for compatibility with standard desktop motherboards while delivering strong bandwidth, efficient power consumption, and reliable long-term operation.

Form Factor

288-Pin UDIMM Layout

The memory module in this category uses the standard 288-pin UDIMM (Unbuffered Dual Inline Memory Module) form factor. This design is made specifically for desktop PCs and some workstation systems. The 288 pins ensure stable electrical connectivity between the memory and the motherboard, allowing fast data transmission and low latency communication.

UDIMM modules are widely supported by mainstream motherboards from major brands, making them ideal for upgrades and new builds alike. Their size and pin layout follow industry standards, ensuring easy installation without special tools or adapters.

Memory Capacity

16GB Single Module Capacity

A 16GB single memory module offers a strong balance between performance and affordability. It provides enough memory for modern operating systems, office productivity software, web browsing with many tabs, and demanding applications like photo editing or software development tools.

Using a single 16GB stick also leaves room for future expansion. Users can add another 16GB module later to enable dual-channel operation and increase total system memory to 32GB without replacing existing hardware.

Dual Rank x8 Architecture

The dual rank x8 design means that memory chips are arranged in two ranks, allowing the memory controller to access different sections more efficiently. Dual rank memory often offers slightly better performance compared to single rank modules in certain workloads, especially in multitasking and memory-intensive tasks.

The x8 chip organization also improves compatibility with a wide range of motherboards and CPUs, ensuring stable recognition and operation.

CL22 CAS Latency

CAS latency (CL22) defines the delay between a memory controller request and the delivery of data. While lower latency is always desirable, CL22 at 3200MHz is well balanced for stability and compatibility across many systems.

This latency ensures smooth performance in real-world tasks while maintaining reliable operation without aggressive overclocking or voltage increases.

Voltage and Power Efficiency

1.2V Low Voltage

Operating at 1.2 volts, DDR4 memory consumes less power than previous DDR3 modules, which typically required 1.5V. Lower voltage means reduced heat output, improved energy efficiency, and longer component lifespan.

This makes such modules ideal for systems that run many hours per day, including office PCs, home servers, and workstations.

Non-ECC and Unbuffered

Non-ECC Memory

Non-ECC memory does not include error correction code functionality. This makes it faster and more affordable than ECC memory, which is typically used in servers and mission-critical systems.

For most desktop and workstation users, Non-ECC memory provides more than enough reliability, especially when sourced from reputable manufacturers and used in quality systems.

Unbuffered Performance Advantages

Unbuffered memory communicates directly with the CPU memory controller without intermediate buffers. This reduces latency and improves responsiveness, making UDIMM modules ideal for consumer and professional desktop use.

Intel Desktop

This category of DDR4 memory is compatible with a wide range of Intel chipsets, including B360, B460, B560, Z370, Z390, Z490, Z590, and many others that support DDR4 UDIMM modules.

It works well with Intel Core i3, i5, i7, and i9 processors that support DDR4 memory, making it suitable for gaming PCs, business desktops, and high-performance workstations.

AMD Platform

AMD Ryzen processors greatly benefit from faster memory. DDR4 3200MHz is often considered a sweet spot for Ryzen systems, offering excellent performance without pushing stability limits.

This module category is compatible with popular AMD chipsets like B450, B550, X470, X570, and many more.

Use Cases

Gaming Systems

Modern games benefit from higher memory speeds and sufficient capacity. A 16GB 3200MHz DDR4 module helps ensure stable frame rates, reduced stuttering, and faster game loading times.

When paired with a capable GPU and CPU, this memory category supports immersive gaming experiences at high settings.

High-Quality DRAM

Memory modules in this category are built using carefully selected DRAM chips that undergo strict testing for speed, stability, and endurance. This ensures consistent performance over many years of operation.

Performance Compared to Other DDR4

Speed DDR4 (2400MHz / 2666MHz)

Compared to 2400MHz or 2666MHz memory, 3200MHz modules provide noticeably higher bandwidth and better responsiveness in memory-sensitive applications and games.
