Samsung 4GB DDR4 PC4-21300, 2666MHZ Laptop Memory

Certainly! Here’s a detailed breakdown of the Samsung 4GB DDR4 PC4-21300 2666MHz laptop memory:
Memory Specifications:
Type: DDR4 (Double Data Rate 4)
DDR4 is the fourth generation of DDR RAM and offers improved speed, efficiency, and power consumption compared to DDR3.
Capacity: 4GB
This module provides 4 gigabytes of RAM, which is suitable for basic multitasking and everyday use. For more demanding applications or gaming, you might need more RAM.
Speed: 2666 MHz (PC4-21300)
This speed refers to the data transfer rate. 2666 MHz is a common frequency for DDR4 RAM, providing a balance between performance and power consumption.
PC4-21300:
This designation indicates the theoretical maximum bandwidth of the RAM module. “PC4” signifies DDR4, and “21300” represents the data rate in MB/s (megabytes per second). For this RAM, it translates to a peak bandwidth of 21,300 MB/s.
Form Factor: SO-DIMM
SO-DIMM (Small Outline Dual Inline Memory Module) is a smaller form factor used in laptops and compact PCs. It differs from the larger DIMMs found in desktop PCs.
Voltage: Typically 1.2V
DDR4 operates at a lower voltage than its predecessor, DDR3, which helps in reducing power consumption and heat generation.
Latency: Typically CL19 for 2666 MHz DDR4
CAS Latency (CL) is the delay time between the read command and the data being available. CL19 is common for 2666 MHz DDR4, but exact timings may vary.
Compatibility:
Laptop: This RAM is designed specifically for laptops that support DDR4 SO-DIMM modules. Ensure that your laptop’s motherboard and CPU support DDR4 memory at 2666 MHz.
Motherboard/Chipset: Verify compatibility with your laptop’s chipset and BIOS. Some systems might have limits on the maximum amount of RAM they can handle or might only support certain speeds.
Installation:
Upgrade: If upgrading, check the current configuration of your laptop (e.g., whether it already has DDR4 RAM and the same speed). Mixing different speeds or brands is generally okay, but all modules will operate at the speed of the slowest module.
Replacement: If replacing, ensure the new module is properly seated in the SO-DIMM slot and is compatible with your system’s requirements.
Performance:
Usage: 4GB of RAM is adequate for basic tasks such as web browsing, office applications, and light multitasking. For more intensive tasks like gaming, video editing, or running multiple applications simultaneously, 8GB or more is generally recommended.
Overall, this Samsung 4GB DDR4 PC4-21300 2666MHz memory module is a reliable choice for improving your laptop’s performance, especially if you’re upgrading from older or slower memory.
