SO-DIMM 256MB PC2100 DDR-266 Computer Memory (RAM)

Choose SO-DIMM PC2-6400 (DDR2-800) Computer RAM for Sufficient Multitasking

The rapid evolution of computer technology is evident in how RAM standards have improved over the years. From dozens of tiny, fragile integrated circuits that you had to install to upgrade your computers memory by a couple of megabytes, modern memory modules consist of single "sticks" that have memory chips soldered in. From there, you connect the RAM module to a computers motherboard by inserting it into the memory banks.

What Is SODIMM PC2-6400 (DDR2-800) Computer RAM?

  • SO-DIMM: This stands for small outline dual in-line memory module, and it is built to be a smaller version of the common desktop RAM or DIMMs. Memory modules can have 200-pin and 240-pin configurations. The 240-pin variants are typically for desktops because of their length while 200-pin and 204-pin SODIMM configurations are shorter and hence built for use with laptop computers. SO-DIMMs are streamlined for use with compact computers because they are installed at a flat orientation ideal for slim designs.
  • PC2-6400 (DDR2-800 MHz): PC2-6400 memory is essentially the same as DDR2-800 MHz RAM. The difference is only in the name. PC2 is a trade name that indicates that the module uses the DDR2 standard, while the number represents the module name. DDR2-800 MHz refers to the friendly name of the module and allows buyers to easily identify the basic specifications of the modules. DDR2 means double data rate version two, which means that the module uses the second iteration of the technology that allows a Non-ECC RAM stick to read and write data at the same time during a clock cycle.
  • Function: DIMM or SODIMM RAM is a crucial component of a computer because it acts as an intermediate memory that is faster than hard drives. Inside a Non-ECC or ECC stick, frequently-accessed data is stored so that it can present that data fast when you launch applications you always use. ECC memory is a more expensive type of memory that can detect and correct data corruption errors but are typically for enterprise applications like servers and databases.

How Do I Choose RAM?

  • Capacity: Choosing a DDR2-800 SODIMM first entails thinking of how much GB memory you need. 1 GB module may struggle with even lightweight tasks, while 2 GB may function but be inadequate. Moreover, 4 GB of memory is good for lightweight tasks, but 8 GB is a sweet spot in terms of value. Commercial DDR2 laptop memory support is limited to 8 GB, however.
  • Speed: An 800 MHz PC2-6400 DDR2 SODIMM should be sufficient for light to moderate workloads, but those with higher speeds of 1066 MHz are also available yet less accessible in terms of cost. These DDR2 sticks come in variants of 400 MHz, 533 MHz, 667 MHz, and the previously mentioned frequencies.
