Prior to checking RAM compatibility, it is important to know what RAM stands for. RAM is an abbreviation of Random Access Memory. RAM, which is installed in the computer, bears resemblance to the short-term memory, which a human brain makes use of for computations. It is well-known fact that people having a sharp short-term memory works much better in comparison to those who do not have it. RAM is volatile by nature. It means that it requires constant electrical power for refreshing itself so that it can store the data contents. As soon as the power is cut, all data, which stored in RAM gets lost. The measurement of RAM is taken in GB (GigaBytes) and MB (MegaBytes). Basically, it is a good idea to upgrade RAM if you make plan to keep your old computer. Below some tips to check RAM compatibility are being explained:

  • First of all, you need to check the package of RAM and confirm whether it says “SODIMM” or “DIMM.” Desktop computers can make use of only “DIMM” whereas laptops make use of “SODIMM.” You can ascertain the difference between a SODIMM and DIMM stick of RAM by perceiving its size. The SODIMM is 3 inches long whereas the DIMM is longer.
  • Confirm how much RAM your PC can take. For store-bought desktop computers and laptops, you need to check the box your computer came in or simply refer to the website of the manufacturer and look for your model number. Spot the model number on the underside or back of your computer. If you made your own computer, you should check the box your motherboard came in or see its model number.
  • Now, switch off your computer and detach its plug from the wall. Detach all the external devices like monitor, keyboard and mouse. Also, take off the case cover if your computer is a desktop model. Read the sticker on RAM to see its specifications and model number. See the model number in case you do not get to see any specifications mentioned on the sticker.
  • At last, you need to check the speed and RAM type against RAM, which you found installed in your PC. Common RAM types are “DDR3,” and “DDR2” and your new RAM must be matchable with the type already installed in your computer. Though less important, the speed of new RAM should be matchable with the speed of your old RAM. Speeds are written in megahertz such as “1066 MHz.”


It should be simple to install a RAM chip but keep in mind the motherboard and whether or not if it’s compatible. Check for instructions on the motherboard or if you are on a computer at the moment while making sure you have the right RAM chip, check online on computer forums.
