What is DDR1 SO-DIMM Memory?

Desktop and laptop computers consist of a number of hardware components, including memory or RAM, that are used to store data required by programs that are running. Memory like DDR1 SDRAM SO-DIMMs are defined by their type, shape, and features which make them suitable for certain situations. Kingston is one brand that manufacturers SO-DIMM memory.

What is Important to Know Before Installing Memory?

Whether you're looking to replace or add RAM to your laptop or desktop computer, there are factors that will impact what type and how much memory you will need, like:

  • Memory Modules: Computer memory comes in the form of memory boards that are referred to as modules. One type of memory module is SO-DIMM memory, also spelled SODIMM, that are much smaller and more compact than regular DIMM modules. Worth knowing is that while a memory kit may come with 8 GB of memory, this could be made up of four modules of 2 GB RAM each.
  • Module Compatibility: The slots on a computer's motherboard are only compatible with a particular type of RAM. In the case of laptops, it may be SODIMM memory modules because of their smaller size. Each type of DIMM and SODIMM memory has a different number of pins and distinct location of their notch or notches. So for example, it's not possible to insert a 260-pin module in the place of a 204-pin SODIMM.

What Are the Defining Features of DDR1 SO-DIMM Memory?

To understand the pros and cons of using Kingston DDR1 SODIMM memory modules, it's important to be aware of the main features of this type of memory, such as:

  • SDRAM Memory: Standing for synchronous dynamic RAM, this type of memory differs from RAM and DRAM by synchronizing with the clock cycle of the computer's processor. This approach means that the timings of the data transfers between the two are predictable increasing the efficiency of their interfaces.
  • Double Data Rate: Memory that uses a double data rate (DDR) interface is able to transfer data twice every clock signal rather than just once, increasing the bandwidth of the data flow through to the processor.
  • Relative Speed: Compared to later generations, like DDR2 and DDR3, DDR1 memory is considerably slower because its internal clock runs as the same speed in MHz as the data bus, which limits its transfer rate. The faster internal clock of later generations can have an impact on latency though.
