A computer’s memory, or RAM, is one of its most important parts, but because numerous types and speeds are available, finding the right module for your PC can be confusing.
RAM stands for Random Access Memory, and that’s exactly what it is – memory that is written to, or read from, at random. The more RAM your PC has, the more tasks it’s able to handle at any one time.
If you don’t have enough memory for Windows Vista to deal with everything you’re asking of it, it’s forced to store information as a temporary file on your hard drive.
A hard drive is a mechanical component, so it operates far slower than memory and, as a result, your PC will feel sluggish and you’ll see a lot of disk activity at random times. Adding more memory will solve this problem, but identifying the correct type and speed for your PC can be a problem in itself.
The easiest way to do this is to use an online memory advisor tool, available from the major memory brand web sites, such as Crucial System Scanner Tool and Kingston Technology. It’s as simple as selecting your PC from an extensive list and choosing the amount you want. If your model isn’t listed, it still needn’t be diffi cult to identify what you need.
The right RAM for you
The freeware program CPU-Z will quickly identify what’s already in your PC. Run the program and under the ‘SPD’ tab you’ll see a list of serial numbers and codes.
At the top, look for the letters SDRAM, DDR or DDR2, which will specify the type of technology your memory uses. SDRAM was used before 2001, DDR memory is still widely used, and DDR2 is rapidly replacing it.
Next, look under ‘Max Bandwidth’ for a number beginning with the letters PC or PC2. The numbers following this denote the memory speed. The alternative is to open up your case and physically take a look. Each module should have a sticker of some form on it, which will state its type and speed.
Once you have the type and speed, you have everything you need to make your purchase. Choose a brand name company such as Corsair or Crucial, as you’ll get a reliable module with a warranty.
1. Open up. Remove the memory module from its anti-static bag. As with any computer part, modules are delicate, so take care when handling them.
2. Slot machine. Memory slots are easy to identify; there’s four of them and they’re identical, with securing clips at either end. Push the securing clips out before you insert the memory module.
3. Clip in place. Place the module in the slot. Press firmly at either end until the clips snap up, securing the module. Memory pairs should be installed in odd or even slots, for example slots one and three.
