AI Verdict
A 16GB DDR5 4800MHz SO-DIMM module for compatible laptops needing a single-rank 1Rx8 memory upgrade.
This 16GB DDR5 4800MHz SO-DIMM module is a standard upgrade for compatible laptops, offering a capacity increase or replacement for existing modules. Its 1.1V operation and JEDEC standard speed make it suitable for general-purpose use in systems that support DDR5.
If you need more performance, look for a matched pair of modules to enable dual-channel operation, or modules with higher speeds if your system supports them.

Pros
- Provides 16GB capacity in a single module, allowing for flexible upgrades.
- Operates at 4800MHz, which is the JEDEC standard speed for DDR5 memory.
- Features a low 1.1V operating voltage, contributing to power efficiency in laptops.
- Non-ECC Unbuffered type, suitable for most consumer-grade laptops and mini PCs.
- Single Rank x8 (1Rx8) configuration.
Cons
- Only offers 16GB capacity, not higher options in a single stick for more demanding users.
- 4800MHz is the base DDR5 speed, not optimized for enthusiast-level performance.
- Non-ECC, making it unsuitable for systems that require error-correcting memory.
- Sold as a single module, so dual-channel performance benefits require purchasing a second identical stick.
- Compatibility is strictly dependent on the specific laptop's motherboard and CPU, requiring manual verification.
Dimension Scores
4800MHz is the base JEDEC standard speed for DDR5, offering standard performance for the category.
It's a standard JEDEC DDR5 SO-DIMM, but compatibility is strictly limited to laptops supporting DDR5 4800MHz and requires checking specific system manuals.
This non-ECC, JEDEC standard module at 1.1V is not designed for overclocking and offers no advertised headroom.
Samsung is a well-established memory manufacturer, generally known for producing reliable components, though no specific user feedback was found for this model.
Best For
- Upgrading a laptop with an existing 16GB DDR5 4800MHz module to a total of 32GB.
- Replacing a faulty 16GB DDR5 4800MHz SO-DIMM in a compatible laptop.
- Adding a second 16GB stick to a laptop with an empty DDR5 SO-DIMM slot to enable dual-channel memory.
- Laptops that specifically require JEDEC standard 1.1V DDR5 4800MHz memory.
Not Recommended For
- Desktop PCs, as it is a SO-DIMM form factor.
- Systems that require ECC (Error-Correcting Code) memory for critical data integrity.
- Users seeking memory modules for extreme overclocking or speeds higher than 4800MHz.
- Laptops that only support DDR4 or older memory generations.
Watch Out For
- Compatibility issues can arise if your laptop does not specifically support DDR5 4800MHz SO-DIMM modules, requiring a manual check of your system's specifications.
- Installing a single module means you won't get the performance benefits of dual-channel memory unless you already have another compatible stick or purchase a second one.
- This 1Rx8 module might not be optimal if your system is designed for 2Rx8 or other ranks, potentially leading to sub-optimal performance or compatibility issues depending on the CPU's memory controller.

Frequently Asked Questions
Is this memory compatible with my desktop computer?
No, this is a SO-DIMM module (262-Pin) designed for laptops, mini PCs, and All-in-One systems, not standard desktop PCs.
Can I use this with DDR4 RAM?
No, DDR5 memory is not backward compatible with DDR4 slots due to different pin configurations and electrical requirements.
What does 1Rx8 mean?
1Rx8 indicates that the memory module is single rank with eight data banks, which describes how the memory chips are organized on the module.
Will this make my laptop faster?
Upgrading to 16GB or increasing your total RAM can improve multitasking and overall system responsiveness if your current RAM is a bottleneck. However, the 4800MHz speed is standard for DDR5, so it won't offer a speed boost beyond that.
Do I need to buy two of these?
If your laptop has two memory slots and you want to enable dual-channel memory for better performance, buying two identical modules is recommended. This module is sold individually.
Buying Guide
When buying laptop RAM, you need to match the DDR generation (DDR5 in this case), the form factor (SO-DIMM for laptops), and ideally the speed (4800MHz here) and voltage (1.1V). Your laptop's motherboard and CPU determine what it can handle, so always check your system's manual first. Don't just assume any DDR5 will work.
DDR5 4800MHz
This is the generation and speed of the memory. DDR5 is newer and faster than DDR4, and 4800MHz is the standard starting speed for DDR5, meaning it's a solid baseline for modern laptops.
SO-DIMM
This refers to the physical size and pin count (262-Pin) of the memory module. SO-DIMM is specifically for laptops and smaller form factor PCs, unlike the larger DIMM modules used in desktop computers.
1.1V
This is the operating voltage of the memory. DDR5 typically runs at a lower 1.1V compared to DDR4, which helps with power efficiency and heat generation in compact laptop environments.
1Rx8 (Single Rank x8)
This describes how the memory chips are organized on the module. Single rank modules can sometimes be slightly faster in certain scenarios, but dual rank (2Rx8) can offer better performance in others, depending on the CPU's memory controller.
Alternatives
If you need more raw speed, look for DDR5 SO-DIMM modules with higher clock speeds like 5200MHz or 5600MHz, but ensure your laptop explicitly supports them. For maximum multitasking, consider 32GB or 64GB modules if your system allows.
