How to Add Physical Memory
Adding physical memory to a computer system can dramatically improve system performance. However, you first have to determine your current system configuration as well as the total amount of physical memory that your system motherboard can support. It is very important to determine the correct type and amount of RAM for your system. Here are step-by-step instructions to assist you in maximizing your physical memory and improving the performance of your computer.

Determine the type and current configuration of your system's RAM. This can be done by reviewing the technical specifications for your particular system on the manufacturer's website. Alternately, you can visit crucial.com and use their free memory advisor tool to give you the information (see Resources). You don't have to make a purchase to use the tool, although if you do decide to purchase through crucial.com and use the tool, they guarantee the RAM to be compatible with your system.

Calculate how much physical memory you can add to maximize your system. You have to take into account the current configuration as well. For example, if your system will hold up to 2 GB of RAM in two slots and you already have the two slots filled with 512 MB memory modules each, then you have to decide to buy enough to max out the system or settle for a little less. RAM prices can fluctuate a lot with supply and demand as well as with advances of technology, so it's a good idea to make sure you have current pricing. Once you are sure you have the right RAM and your system configuration figured out, it is time to crack the case open.

Use the Phillips screwdriver to remove the screws on the back of the computer that are holding on the case cover. Be sure that the computer is unplugged before you begin. Put on your ESD wrist strap to remove any static electricity before you touch anything on the inside of the case or the new physical memory modules. Alternately, you can ground yourself and discharge static electricity by using the computer case chassis as a ground. The idea is to equalize the charge between you and the computer before touching any electronic components.

Locate the RAM slots on the motherboard. They will have the same type of modules plugged in as the ones you purchased, and will be held in place by plastic clasps on each end. To remove, gently press down on the clasp on each end and the module will pop up. Only remove the modules that you have to replace.

Insert new physical memory modules by gently pushing down into the slot, ensuring that the notch on the bottom is oriented correctly. Note that it will only fit in the slot one way. Make sure the module is properly seated by pushing gently on each end until the clasps snap into place. Put the case back together and plug the computer back in. Once you boot it back up, most modern computers will automatically recognize and begin using your new physical memory.

Tips & Warnings
Buy RAM from a reputable source that will help you. RAM is very specific based on the computer system involved. Recycle your old RAM by selling it on eBay or Craigslist. It will also help offset the cost of your new RAM modules.
Never open a computer case without unplugging the electrical cord first. Never touch electronic components without discharging static electricity from your body. Never force physical memory into the RAM slots. Excessive force can cause damage to the motherboard.
