Why You Should Consider Upgrading Your Computer System Memory (RAM)

Random Access Memory (RAM) is an important part of your computer's system memory. When you are using your computer, your system places your programs in RAM temporarily enabling the processor can access data faster and more easily. Generally, the more memory your system has, the larger the temporary storage and the faster your programs will run. If your system is running slowly, upgrading RAM might be all you need to maximize performance.

What Is a DDR2 SODIMM Laptop Memory?

DDR2 is the second-generation double rate SDRAM interface. It succeeded DDR providing new features, greater bandwidth, and lesser power consumption. DDR2 SODIMMs (or SO-DIMMs) are for use in small-sized devices such as notebook PCs. The modules feature 200-pin connectors and offer clock rates and data transfer speeds of 400 MHz, 533 MHz, and 667 MHz.

What Are the System Requirements for Installing a DDR2 SDRAM?

Before getting any memory module, there are some important considerations you should make.

  • Interface compatibility: DDR2 SODIMMs typically appear in laptops and notebooks. Desktops usually use DIMMs, but some also come with additional SODIMM sockets. Although both DDR1 SODIMMs and DRR2 SODIMMs have 200-pin connectors, the two interfaces are not compatible. The notch on DDR2 SO-DIMMs is in a different position from DDR SODIMMs.
  • Operating system limitations: Most modern systems are equipped with a 64-bit operating system. However, there are still some systems that utilize 32-bit operating systems. When replacing your RAM, you should ensure that your operating system will support your preferred memory capacity. 32-bit OS users can only install a maximum of 4 GB memory.

In addition to the system requirements, you should also look at the speed and latency of the DDR2 SODIMMs. Common DDR2 speed ratings include PC2-4200 (4.2 Gbps), PC2-5300 (5.3 Gbps), and PC2-6400 (6.4 Gbps). RAM timings (latency), on the other hand, express in numbers like 3-4-4-8, 5-5-5-15, or 6-6-6-18. The lower the numbers, the better.

What Are the Main Features of 4 G DDR2 533 (PC-4200) SO-DIMM Laptop Memory?

  • Performance: DDR2 533 (PC-4200) RAMs operate at a maximum clock speed of 533 MHz and throughput (bus speed) of 4200 Mbps. The RAMs also boast low latency for faster responses. With 4 GB DDR2 memory modules, you can smoothly run common applications such as browsing and typing. Users running memory intensive programs like Photoshop and 3D design can enjoy a smooth performance by installing 2 x 4 GB memory kits.
  • Error-correcting code (ECC): DDR2 SODIMMs feature both ECC and NON-ECC variants allowing users to choose the right module for their computer system.
  • Power consumption: DDR2 S0-DIMMs have low voltage making them ideal for use in laptops. Due to their low power consumption, they release less heat helping increase their durability as well as the longevity of your battery.
