AI Verdict
A 4GB 3200MHz 1Rx16 DDR4 SODIMM for basic laptop upgrades or specific compatibility needs, operating at 1.2V.
This 4GB 3200MHz 1Rx16 SODIMM is a very specific upgrade. It's fine for basic tasks or replacing an identical module, but the 4GB capacity and 1Rx16 rank mean it won't transform a laptop's performance for anything beyond light use.
If you need more than basic performance, look for an 8GB or 16GB module, preferably with a 1Rx8 or 2Rx8 configuration, and aim for a lower CAS Latency (e.g., CL16 or CL18) if your system supports it.

Pros
- 3200MHz speed is standard for DDR4, providing adequate data transfer rates for compatible systems.
- Operates at 1.2V, contributing to lower power consumption in laptops.
- Samsung is a recognized manufacturer of memory components, implying manufacturing quality.
- SODIMM form factor and 260-pin configuration ensure compatibility with most laptops supporting DDR4.
Cons
- 4GB capacity is limiting for modern multitasking and demanding applications.
- 1Rx16 configuration can result in lower memory bandwidth and increased latency compared to 1Rx8 modules, potentially impacting performance in some scenarios.
- CAS Latency of CL19 is not the lowest available for 3200MHz DDR4, meaning slightly slower response times.
Dimension Scores
3200MHz is standard for DDR4, but the 1Rx16 configuration and CL19 latency are not optimal for performance-critical tasks.
As a standard 260-pin DDR4 SODIMM at 1.2V, it's designed for broad compatibility with laptops supporting DDR4 memory.
This is a standard JEDEC module with no advertised overclocking capabilities or XMP profiles.
Samsung is a major manufacturer of memory components, generally associated with high manufacturing standards and reliability.
Best For
- Basic laptop upgrades for web browsing and document editing.
- Replacing a failed 4GB 1Rx16 module in a compatible laptop.
- Specific budget laptops that originally shipped with 1Rx16 RAM and benefit from matching the existing module.
- Systems where 4GB is sufficient for the intended light workload.
Not Recommended For
- Gaming or performance-intensive applications due to 4GB capacity and 1Rx16 configuration.
- Heavy multitasking or professional content creation.
- Users expecting significant performance gains from a single 4GB module.
Watch Out For
- Performance limitations due to the 1Rx16 configuration, which can lead to lower bandwidth and higher latency compared to 1Rx8 modules, especially noticeable in CPU-intensive tasks or gaming.
- 4GB capacity quickly becomes a bottleneck for modern operating systems and applications, leading to frequent disk paging and system slowdowns.
- Compatibility issues can arise if the laptop's motherboard or CPU memory controller does not fully support the 1Rx16 configuration or 3200MHz speed, though less common with standard JEDEC modules.

What Buyers Say
Specific user reviews for the Samsung M471A5244CB0-CWE 4GB 3200MHz 1Rx16 SODIMM are not readily available across major retail platforms or forums. While the product holds a 4.7/5 rating from 619 reviews on Amazon, these are general ratings for the product listing and not specific user comments for this exact module. Expert analysis suggests that the 1Rx16 configuration, while common in budget laptops, can lead to lower memory bandwidth and increased latency compared to 1Rx8 modules, impacting performance in demanding scenarios like gaming. The 4GB capacity is also a significant limitation for modern computing.
“Needed a cheap 4GB stick for an old laptop that barely runs Windows, and this did the trick, but don't expect miracles, it's just 4GB.”
Common Praise
- Works as a direct replacement for existing 4GB 1Rx16 modules.
- Easy installation in compatible laptop slots.
- Provides a basic memory upgrade for older or low-spec laptops.
- Stable operation at advertised 3200MHz speed and 1.2V.
Common Complaints
- Limited performance due to 1Rx16 chip organization, especially compared to 1Rx8 modules.
- 4GB capacity is quickly maxed out by modern operating systems and applications.
- No noticeable performance boost when added to systems already struggling with low RAM.
- Potential for compatibility issues if mixed with dissimilar RAM modules.
Ownership Tips
- Check your laptop's existing RAM configuration (1Rx8 vs 1Rx16) before purchasing to avoid potential performance mismatches.
- Ensure your laptop has an available SODIMM slot or that you are replacing an existing module.
- Verify the maximum RAM capacity supported by your laptop's motherboard.
- For dual-channel performance, purchase two identical modules rather than mixing.
Frequently Asked Questions
Is this RAM compatible with my laptop?
This is a 260-pin DDR4 SODIMM module operating at 1.2V and 3200MHz. Check your laptop's specifications to ensure it supports DDR4 SODIMM RAM at this speed and voltage.
What does 1Rx16 mean?
1Rx16 refers to the memory's rank and chip organization. It means it's a single-rank module with x16 width memory chips. This configuration can sometimes offer lower performance than 1Rx8 modules in certain applications.
Can I mix this with my existing RAM?
While technically possible, mixing RAM modules with different capacities, speeds, or ranks (like 1Rx16 with 1Rx8) can lead to instability or prevent dual-channel mode from activating, potentially reducing performance. It's generally recommended to use identical modules.
Is 4GB enough RAM for a laptop?
For basic tasks like web browsing, email, and word processing, 4GB can be sufficient. However, for multitasking, gaming, or more demanding applications, 4GB will be a significant bottleneck.
What is CAS Latency (CL19)?
CAS Latency (CL) is the delay time between the memory controller requesting data and the data being available from the RAM. CL19 at 3200MHz is a standard latency for DDR4, but lower numbers (e.g., CL16) indicate faster response times.
Buying Guide
When buying laptop RAM, you're looking for a specific type (DDR4), form factor (SODIMM), and speed (MHz) that matches your laptop's motherboard. Capacity (GB) dictates how many applications you can run smoothly. The 'rank' (like 1Rx16) and CAS Latency (CL) also affect performance, with 1Rx8 generally offering better bandwidth than 1Rx16 for the same speed.
Capacity (4GB)
This is how much data your laptop can hold in active memory. Think of it like the size of your desk; a bigger desk (more GB) means you can have more books (programs) open and switch between them without putting some away (swapping to slower storage).
Speed (3200MHz)
This is how fast the RAM can transfer data to and from your processor. Higher numbers mean quicker data flow, like a wider highway for information. Your system will only run at the speed supported by your motherboard and CPU, or the slowest installed module.
Rank (1Rx16)
This describes how the memory chips are organized on the module. 1Rx16 modules have fewer, denser chips, which can sometimes result in lower memory bandwidth compared to 1Rx8 modules, potentially affecting performance in certain tasks.
Alternatives
If this 4GB module isn't enough, search for DDR4 SODIMM modules with higher capacities (8GB or 16GB), preferably with a 1Rx8 or 2Rx8 rank, and a lower CAS Latency if your laptop supports it.
