AI Verdict
An 8GB DDR4 3200MHz CL22 1Rx16 SODIMM from Samsung for upgrading compatible laptops to 16GB total.
This 8GB DDR4 3200MHz CL22 1Rx16 SODIMM is a direct upgrade for many compatible laptops, especially when adding a second stick to enable dual-channel memory. However, its 1Rx16 configuration means it won't deliver the same peak bandwidth as a 1Rx8 module, which can impact performance in some scenarios.
If you're chasing maximum performance, especially with integrated graphics, look for 1Rx8 or 2Rx8 dual-rank modules.

Pros
- Genuine Samsung module, ensuring quality and compatibility.
- 3200MHz speed (PC4-25600) for modern DDR4 laptops.
- Standard 1.2V operation for energy efficiency.
- Non-ECC Unbuffered design suitable for consumer laptops.
- Straightforward installation for compatible systems, improving responsiveness.
Cons
- Single 8GB capacity might be insufficient for heavy multitasking or demanding applications.
- 1Rx16 single rank configuration can result in lower bandwidth compared to 1Rx8 modules, especially for integrated graphics.
- CL22 latency is standard JEDEC, not a low-latency option for performance enthusiasts.
- No specific thermal solution, though typical for SODIMM modules.
Dimension Scores
3200MHz CL22 is the JEDEC standard for DDR4 SODIMM, not a performance-tuned option.
Widely compatible with DDR4 laptops, but 1Rx16 can be a specific compatibility or performance consideration for some systems.
This is a JEDEC standard module, not designed for overclocking.
Samsung is a major memory manufacturer with a reputation for producing dependable components.
Best For
- Upgrading a laptop with a single 8GB 1Rx16 stick to 16GB total in dual-channel mode.
- Replacing a failed 8GB DDR4 SODIMM in a compatible laptop.
- Laptops used for general tasks like web browsing, word processing, and media consumption.
Not Recommended For
- High-end gaming laptops or professional creative workstations requiring higher capacity or lower latency.
- Systems that do not support DDR4 memory.
- Desktops, as this is a SO-DIMM module.
Watch Out For
- The 1Rx16 configuration can lead to a performance bottleneck compared to 1Rx8 modules, especially in systems with integrated graphics or AMD CPUs.
- Some laptops might be sensitive to RAM rank (1Rx8 vs 1Rx16), potentially causing compatibility issues or reduced performance if not matched correctly.
- Not suitable for systems that require ECC memory, as this is a Non-ECC module.
- While genuine Samsung, the exact part number received might vary, though specifications are stated to be identical.

What Buyers Say
Many users report a noticeable speed increase and improved multitasking after installing this RAM, especially when moving from a single 8GB stick to 16GB in dual-channel mode. The main point of discussion among more knowledgeable users revolves around the 1Rx16 configuration and its potential bandwidth limitations compared to 1Rx8 modules.
“Dude, my old laptop was chugging with 8GB, but throwing this Samsung stick in there made a real difference, everything just opens faster now, though I wish I knew about the 1Rx16 thing before, but it's still way better.”
Common Praise
- System feels faster and more responsive after installation.
- Easy to install in compatible laptops.
- Genuine Samsung quality gives peace of mind.
- Improved loading times for applications.
- Effective for general tasks and casual use.
Common Complaints
- The 1Rx16 configuration might not deliver optimal performance compared to 1Rx8, particularly for integrated graphics or AMD CPUs.
- Some users might not see a dramatic performance boost if their usage doesn't demand more than 8GB or if their system already has dual-channel memory.
- Not suitable for high-end gaming or intensive professional applications due to capacity and rank.
Ownership Tips
- The laptop's battery life seems unaffected, likely due to the 1.2V low voltage design.
- Even with the 1Rx16, the jump to 16GB dual-channel feels significant for everyday use.
- Checking the exact part number received against the listed equivalents is a good idea, though performance should be identical.
Frequently Asked Questions
Is this compatible with my [laptop model]?
You need to check your laptop's specifications to confirm it supports DDR4 SODIMM, 3200MHz speed, and 1.2V voltage.
Can I mix this with another brand of RAM?
Yes, but for optimal stability and performance, it's best to match the speed, voltage, and CAS latency of your existing RAM.
Is this 1Rx8 or 1Rx16?
This specific module is 1Rx16 (Single Rank x16).
What's the difference between PC4-25600 and 3200MHz?
They both describe the speed; 3200MHz is the clock speed, and PC4-25600 is the theoretical peak transfer rate (25.6 GB/s).
Will this work in a desktop?
No, this is a SO-DIMM module designed for laptops and small form factor PCs, not standard desktop DIMM slots.
Will adding this improve my gaming performance?
If your laptop currently has a single 8GB stick, adding a second one to enable dual-channel memory can significantly improve gaming performance, especially with integrated graphics.
Buying Guide
When buying laptop RAM, you're looking to match what your system already has or what it can support. Think of RAM like lanes on a highway; more lanes (capacity) and faster cars (speed) mean smoother traffic. But also, how those lanes are organized (rank) can affect how much traffic flows at once.
Capacity (8GB)
This is how much information your computer can actively work with at one time. More capacity means you can open more programs or bigger files without your system slowing down to swap data to the slower storage drive.
Speed (3200MHz)
This is how fast the RAM can process data. Higher numbers mean quicker operations, like a faster car on the highway. Your system will only run at the highest speed supported by both the RAM and your laptop's motherboard.
Voltage (1.2V)
This is the power the RAM needs. Most modern DDR4 laptops use 1.2V, which is more energy-efficient than older standards, helping your battery last longer.
Rank (1Rx16)
This refers to how the memory chips are organized on the module. 1Rx16 means there's one rank of memory using x16 width chips. While still 3200MHz, it can sometimes offer slightly less bandwidth than a 1Rx8 module, which might matter for integrated graphics performance.
Alternatives
If you need more capacity, look for 16GB or 32GB SODIMM modules. For maximum performance, especially for integrated graphics, prioritize 1Rx8 or 2Rx8 dual-rank modules with the same speed and voltage.
