How to Choose a Computer RAM

Bookmark and Share
Which type of computer RAMs to buy? What is the speed of computer RAM that we are purchasing? How much memory is sufficient? Where can we find a reputed retailer? – These are a few questions that we often ask to get a better performance from our PC. Undoubtedly, bigger memory size of any RAM results into more data storage. One can easily notice the difference in speed & efficiency after upgrading RAM from 128MB to 256MB or 512MB to 1GB or 1GB to 2GB. But while choosing a computer RAM, we should be aware of some basic facts about this sensitive part of our computer.
Computer RAM or Random Access Memory is one such crucial part that provides a temporary data storage. For general use, we can choose from a wide range of SDRAMs & DDR RAMs. SDRAM, usually compatible with Pentium 2 or Pentium 3 processor systems, is rapidly becoming obsolete. With advanced technology, the computers today are manufactured with a high compatibility factor towards DDR RAM or DDR2 RAM. To add to the list, DDR3 RAM is the recent invention that takes the computer efficiency to another higher level.
Another interesting thing is dual channel that you will come across while going through the computer RAM manual guide. This is one such added feature in almost all the present-day computers which lets us utilize the bandwidth of two memory modules at the same time to serve the purpose of upgrading computer. This means, if you are using a 512MB RAM in your computer and you wish to upgrade it to 1GB. In that case, if you buy a 1GB RAM – your 512MB RAM will be of no use. So instead of going for a 1GB module, you can buy another 512MB RAM and install it with the older one. This way, you can get your system upgraded to double RAM at a lower price without wasting your old RAM. Same technique can be done while upgrading the computer from 1GB RAM to 2GB RAM or even more.
Next, you should know about your usage capacity. If you are a person with soft skills, there would be no use of 2GB, 3GB or 4GB RAMs for you. Higher RAM modules are not required unless you spend a lot of time while playing games or editing music or videos. To serve the purpose, the standard versions of Windows XP & Vista recognize RAMs only up to 3GB. Some of the RAM modules, recommended for better use of operating system, are listed as:
  • Windows 98 / Windows Me: 256MB to 512MB RAM
  • Windows 2000 / Windows XP: 1GB to 4GB RAM
  • Windows Vista / Windows 7 32-bit: 2GB to 4GB RAM
  • Windows Vista / Windows 7 64-bit: 6GB to 16GB RAM
  • Linux with 32-bit: 1GB to 4GB RAM
  • Linux with 64-bit: 4GB to 16GB RAM
Therefore, it is advised to go through the manual of computer first before purchasing an additional RAM to upgrade your PC. Obviously, there would be no use of additional higher RAM if your system’s motherboard belongs to an old version & it is not compatible with the type of RAM you have purchased.
