Computer Memory Tips

What is RAM?
RAM is an anonym that stands for random access memory. In short this is like a scratch pad. As the computer works on various things (instructions sets) it needs a place to temporarily hold or remember things as it does its work (computing). So the more RAM you have the bigger your scratchpad is the more your computer can remember and do without having to store this information on the hard drive. Keep in mind the scratchpad is a temporary work space and is lost when the computer shuts down. Any information needed for a longer period of time is stored on a hard drive. It takes time to store data on a hard drive. It may seem very quick to you but this is an eternity in computer time. By utilizing the scratchpad which is all electronic (no moving parts) and faster than a hard drive (contains moving parts) your computer can do its processing much faster. So, if you feel the need for speed then get more RAM.
How much RAM does my computer really need?
Unfortunately it’s not always that easy. For Windows based computers, no MACs please, the amount you need or the better way to phrase the statement is; the amount of RAM your computer can actually use is based on what version of the operating system is installed and your motherboard. The motherboard is where the memory plugs in. It’s where all the devices are connected together. Motherboards come in either 32-bit or 64-bit configurations. Having a larger 64-bit motherboard will allow your computer to address more memory. Theoretically 64-bit computers can access 17.2 billion gigabits of RAM. A 32-bit computer can access 4 gigabits of data. Not all computers can actually use all 17 plus gigabits. This is because most software is only 32-bit and can only address up to 4 gigabits. There are 32-bit and 64-bit versions of the operating system. And 64-bit operating systems can address more RAM. So, if you have a 64-bit motherboard and a 64-bit operating system then your computer can address more RAM. In this case you will want to have more RAM to make your system run faster.
Here is what you need generally speaking:
- 2 gigabits for RAM is more than enough for 32-bit systems or
- 4 gigabits likewise for 64-bit systems.
Microsoft recommends 4GB of RAM for 64-bit operating systems of Windows Vista. Vista Home Premium can access 16GB of RAM and Vista Ultimate can access 128GB. I do some heavy duty computing and have never used this much RAM. I would advise staying with 2 gigabits for 32-bit systems and 4 gigabits for 64-bit systems. There are some exceptions. If you are a serious gamer you will need additional RAM and other specialized hardware like video cards, etc. In addition, if you do serious video editing you will need more RAM and even opt for a 64-bit system or run heavy duty big databases like some business do. Most everyone else runs on 32-bit systems (32-bit operating systems like Windows 7 or Vista) and 2 gigabits of RAM. Anything more is a waste because most likely it will never be used.
There are many computers that have dramatically improved their speed by adding more memory or RAM. In many cases this is a very good cost effective way of extending the life of your system for a year or more. This enables you to continue to use your old system and not have to buy a new one.
Remember most likely all you will need is a maximum of 2 gigabits.
