RAM or Random Access Memory is the primary memory of your computer. All the programs that run on a system are first brought over on this memory and then executed. Thus, more RAM means more speed.
The first thing that you need to know is that the RAMs available in the market are in the multiples of 16 MB. This means that they will have the size of 64 MB, 128 MB, 256 MB, 512 MB, 1024 MB or 1 GB, 2 GB, 4GB, 8GB, etc. Once, you have decided on the size, you need to check the card type.
The card type is generally referred to as a form factor. If you have DIMM slots in the system, you will need a RAM compatible with that slot. Whereas, for RIMM slots, you will need the one that meets its requirements. You also need to check that the existing primary memory in your system is a DDR or SDR.
When installing the RAM in a desktop computer, you first need to open the CPU. Opening it should not be a difficult task. Most of the CPUs designed nowadays, generally have hand-driven screws. Remember to switch off the machine and unplug all the connections from the power supply.
To prevent any accidental static current flow, stand on an insulator before starting off with the installation process. Also, unplug the connections to any other computer peripherals from the CPU cabinet. In short, all the wires connected to the CPU need to be removed.
The new RAM needs to be installed in what we commonly refer to as the memory bank. There will be slots near your existing RAM to install the new one. For installing a DIMM type, hold it perpendicular to the motherboard and parallel to the existing RAM. Simply push it into its slot.
For installing a SIMM (Single Inline Memory Module) type, you will have to hold it at approximately 45 degrees to the slot and push it forward. Locate the notch and see its direction before doing so. If there are any metal clips, then you need to fix them at the end.
Generally, in the present computer motherboards, there are no additional clips at the end of the slot. You must have noticed the small holes on each side of the SIMM. Make sure they fit in properly into their respective holders. Try to pull out the module again to check, if it has fit in properly.
Once you are done, close your CPU cabinet and plug-in all the peripherals and then connect the computer to the power supply. Switch on the computer and check if the amount of RAM that you have added is being displayed.
If you are using a Windows operating system, simply right click on My Computer and go to Properties. Here, you will get to see the details regarding newly installed memory.
If in case you do not see it, then repeat the entire procedure again. When discussing compatibility, one thing that needs to be mentioned is that a wrong RAM can spoil the card, the memory slots, and even the system. So, in case of any confusion, take the help of a professional. Your computer manual will be your bible throughout the process.
Besides, if you have got the wrong type, it will not fit into the slots, and you should not try to do it forcefully. These mentioned guidelines apply only to the desktop computers. If you want to install the RAM in a laptop, it is better to take help of a professional.
