Your next step will be to install your memory modules in the appropriate motherboard slots making sure that modules are supported. Extreme care should be exercised to prevent static electricity damage to modules.
Purchase memory in dual channel DDR2 or DDR3 kits; that is, identical pairs per kit.
Prepare memory slots by opening the clips. Carefully hold modules and ensure proper alignment. Firmly press modules into slots until clips are completely closed and ensure that they are properly installed. (See Diagram A below).
Memory modules come in different types such as 168-pin PC100 and PC133 SDRAM used in old computers. These have now become obsolete and are being replaced by 184-pin DDR and 240-pin DDR2 and DDR3 SDRAM modules which have faster access times and greater bandwidth.
