Pros
- Provides 8GB of DDR4 memory, a common capacity for laptop upgrades.
- Operates at a standard 2400 MHz frequency, compatible with many older and mid-range laptops.
- Uses the 260-pin SO-DIMM form factor, specifically designed for laptops.
- Runs at 1.2 Volts, adhering to the DDR4 low-power standard.
- Users report straightforward installation and immediate system recognition.
- Reported to work without issues in various laptops, including Lenovo ThinkPads and Synology NAS devices.
Cons
- 2400 MHz is an entry-level DDR4 speed, not suitable for systems requiring higher memory bandwidth.
- Sold as a single 8GB module, requiring a second purchase for dual-channel configurations.
- The 'CRC' suffix, indicating a 2400MHz speed bin, might be hard to match exactly for some users trying to find an identical stick for dual channel.
- No Error-Correcting Code (ECC) support, which is standard for consumer laptop memory but a limitation for some server-grade applications.
Dimension Scores
At 2400 MHz, this DDR4 module offers category-average speed for entry-level and mid-range laptops, but is not the fastest available for DDR4.
As a standard 260-pin SO-DIMM operating at 1.2V, it shows broad compatibility with a wide range of laptops and devices designed for DDR4 2400MHz memory.
This standard SO-DIMM is not designed for overclocking, and laptop motherboards typically do not offer BIOS options for memory overclocking.
Samsung is a major memory manufacturer, and user feedback consistently points to stable and problem-free operation.
Best For
- Upgrading older or entry-level laptops with 4GB or 8GB of existing RAM to 8GB or 16GB total.
- Users needing to replace a failed 8GB 2400MHz DDR4 SO-DIMM in a laptop.
- Expanding memory in compatible Synology NAS devices that support SO-DIMM DDR4.
Not Recommended For
- High-performance gaming laptops or workstations that benefit from 3200MHz or faster DDR4.
- Desktop PCs, which use larger DIMM modules.
- Systems requiring ECC memory for data integrity.
Watch Out For
- Finding an exact match for the 'C-die' or 'B-die' versions and 'CRC' suffix can be challenging when attempting to match existing RAM for dual-channel operation.
- If paired with a slower existing module, both sticks will operate at the speed of the slowest module, potentially limiting the 2400MHz performance.
- Some users report needing to ensure the CAS latency matches their existing RAM for optimal compatibility, though this is less critical for non-overclocking laptop use.

What Buyers Say
Users frequently purchase this Samsung 8GB 2400MHz SO-DIMM for laptop memory upgrades, often to match an existing stick for dual-channel operation. Many report that it's recognized immediately by their system and functions without issues, particularly in Lenovo ThinkPads and Synology NAS devices. While specific complaints about the module's performance are absent, the main challenge users face is ensuring an exact match for the specific 'die' or suffix (e.g., 'CRC' vs 'CTD') when trying to pair it with pre-installed RAM.
“Needed to upgrade my old HP laptop from 4GB, this Samsung stick popped right in and now Windows isn't constantly freezing up, feels like a new machine for real.”
Common Praise
- System recognizes the module instantly upon installation.
- Functions without stability issues or blue screens in various laptops.
- Successfully pairs with existing 8GB 2400MHz modules for 16GB total memory.
- Provides a noticeable performance boost for systems upgrading from 4GB RAM.
- Works as expected in specific devices like ThinkPad T480 and Synology DS920+.
Common Complaints
- Difficulty in finding an identical module (same 'die' or suffix) to perfectly match existing RAM for dual-channel setups.
- No specific complaints about the module itself, but general user challenges with RAM compatibility when mixing brands or speeds.
Ownership Tips
- Check your laptop's existing RAM speed and voltage to ensure this module is a compatible match for optimal performance.
- If adding to existing RAM, verify the CAS latency of your current stick to minimize potential compatibility quirks, though it's often not a dealbreaker for laptops.
- The 'CRC' in the model number indicates a 2400MHz speed bin, which is useful for matching if you're trying to find an identical module.
- Installation is typically tool-free in most laptops, requiring only opening a memory access panel.
Frequently Asked Questions
Is this RAM compatible with my laptop?
This module is a 260-pin DDR4 SO-DIMM operating at 2400 MHz. You need to check your laptop's specifications to ensure it uses DDR4 SO-DIMM memory and supports 2400 MHz speed.
Can I use two of these for dual channel?
Yes, if your laptop has two SO-DIMM slots and supports dual-channel memory, you can install two of these modules for a total of 16GB in a dual-channel configuration. This can improve memory bandwidth.
Will this work with my existing RAM if it's a different brand?
Generally, yes. RAM from different brands can often work together, but it's best if the speed (2400 MHz) and voltage (1.2V) match your existing module. If speeds differ, both modules will run at the slower speed.
What does '2400 MHz' mean?
2400 MHz refers to the memory's clock speed, indicating how many cycles per second it can perform. A higher MHz generally means faster data transfer, but your system's motherboard and CPU must support that speed.
Is this RAM good for gaming?
For casual gaming or older titles, 8GB of 2400MHz DDR4 is adequate. However, for modern demanding games, 16GB (using two of these) or faster memory (3200MHz+) would provide a better experience if your system supports it.
Buying Guide
When buying laptop memory, you're essentially looking for the right fit for your machine. You need to know the physical size (SO-DIMM for laptops), the generation (DDR4 is what this is), and the speed (2400 MHz here). Getting these three right means your laptop will recognize and use the new memory. More RAM lets your computer handle more programs at once without slowing down, and faster RAM can make those programs run a bit snappier.
Capacity (8 GB)
This is how much data the memory can hold at one time. Think of it like your desk space; 8GB means you have enough room for several applications and browser tabs open simultaneously without constantly shuffling things around. If you only have 4GB, upgrading to 8GB or 16GB (with two sticks) makes a huge difference in how 'snappy' your laptop feels.
Type (DDR4)
This refers to the generation of memory technology. DDR4 is newer and more efficient than older DDR3 or DDR2. Your laptop's motherboard is designed for a specific DDR type, so you can't mix and match; a DDR4 slot only accepts DDR4 memory.
Speed (2400 MHz)
This is how fast the memory can transfer data. Higher numbers mean faster data transfer, which can translate to quicker program loading and smoother multitasking. However, your laptop's CPU and motherboard have a maximum speed they can support, so buying faster RAM than your system can handle won't provide any benefit.
Form Factor (260-Pin SO-DIMM)
This is the physical size and pin configuration of the memory stick. SO-DIMM (Small Outline Dual In-line Memory Module) is the compact version used in laptops, while desktops use larger DIMMs. The 260 pins are the electrical contacts that connect the module to your motherboard.
Alternatives
If this module doesn't fit your needs, search for DDR4 SO-DIMM memory with capacities of 16GB or 32GB if you need more multitasking power, or speeds of 3200MHz or higher if your laptop supports it for increased performance.
