How to Buy Computer Memory
From LoveToKnow Buy
One of the benchmarks of computer performance is memory, or RAM. RAM acts as a quick, temporary storage space for your computer to use while it's working. The more memory you have, the faster your computer runs. With software becoming increasingly complex, programs demand more and more memory allocation from your computer. If you want to boost your RAM and thus your computer's speed, follow these simple tips to get the best for your money.
Computer memory upgrade basics
Computer memory chips are actually small circuit boards that contain a group of memory chips in 32-bit or 64-bit bus widths called a SIMM (Single In-Line Memory Module). Older machines usually have megabyte chips and newer ones have larger gigabyte chips installed. To boost available memory, you’ve got to know which type of memory chip configuration and the number and type of pins each SIMM chip has.
Most RAM available at computer hardware stores and online will be for newer computers made in the last few years. If you aren't sure which type of memory to buy, consult your owner's manual or tell a sales representative the make and model of your PC.
Is adding computer memory hard to do?
Adding more memory to older PC computers isn't as difficult as it may seem. However, adding memory to newer machines is a challenge, mainly because newer machines are much more compact than older models.
With older models, the SIMM chips are easily accessed. All you have to do is snap open the retaining clips, pull out a SIMM and replace it with another.
With newer machines, the SIMMs may be buried under other components. Should this be the case, or if you are more than a little fearful of probing the innards of your computer, take it to a professional for the installation.
This illustrated guide will help you install memory to your computer. Remember: if you're feeling hesitant, ask a computer-knowledgeable friend to help, or take your PC to a shop.
How much computer memory do I need?
Most machines come pre-installed with one of the following amounts of memory:
- 128 MB
- 256 MB
- 512 MB
- 1 GB (1000 MB)
Depending on what you use your computer for, 512 MB is usually sufficient. If it's lower, consider upgrading.
