RAMs for Laptop

Random access memory or commonly known as RAM is the most important component of laptops and desktops. Performance of a laptop depends on three basic laptop accessories that includeHard drive, Processor and RAM. So when choosing suitable RAM for a laptop or a desktop, users should know the difference between different type of RAMs. Laptops have different type of RAM, with different size and shape. Laptops have a small outline dual in-line Memory Module or SO-DIMM, which is different from the desktop computers. These modules have better performance when used with the hard drive and processor of equal capacity.

Random access memory has many types of laptops and these are available in different pin settings and clock speed. Depending on the processor and hard disk, users can upgrade RAM at any time from any computer retail store. Laptop RAMS have many types and depending on the RAM slot in the motherboard, users can install RAM into their laptops. In the following paragraphs types of RAMs and their features will be added.

  • DDR- Random Access Memory

The first type to be discussed is DDR, 200 pin RAM. These types of RAMs come in three different models which have different configuration. DDR actually means the double data rate. Older laptops used these types of RAM and DDR is capable of sending data twice the rate of SDRAM which are also known as synchronous dynamic random access memory. Which means DDR can Send the data in both clock shifts, which include 0-1 and 1-0 transitions. DDR is available in different speeds for different type of laptops and many of the cheap laptops are still using this RAM.

  • DDR2- Random Access Memory

After the DDR came the much faster and better DDR2 RAMs with speed varying from 400 MHz to 800 MHz. This RAM was compatible with a different RAM slot and DDR cannot be attached to the laptops having DDR2 slot. Although both of them had same basic characteristics that is data sending in both clock transitions, but the main difference was about the amount of data sent by the DDR2. DDR2 was capable of allowing more data to travel in both shifts with more bandwidth. Many of the laptops and cheap notebooks uk after 2006-07 had DDR2 RAMs.

  • DDR3- Random Access Memory

After DDR2 came the latest RAM with the capability of speeds from 800 MHz to 1.6 MHz. All the latest desktops and laptops have DDR3 slot and only this type of RAM can work on this. These RAMs are faster in data sending than the other two types and consume less power. DDR3 has the capability to control signal time delay and so far is the fastest and the most efficient random access memory available for the laptops.
