Even before Vista was released, experts have already warned about the operating system’s appetite for RAM. Indeed, it’s the most demanding program as far as system resources are concerned. 2GB would usually already suffice for Microsoft’s latest OS. However, you might be in for a surprise when you take a peek at your system’s gauges.

Being the OC that I am with regard to system performance, I usually check on the meters as to how my PC is doing. Upon checking my RAM, I was surprised to discover that only a tiny fraction of it was left available. I nearly panicked, thinking that one or both my SIMM modules are either defective or totally went dead on me.

Before rushing to the phone to call my RAM maker’s customer service hotline, I decided to pour ice-cold water on my simmering fear and anxiety first by researching on the problem. I was only a few pages on Vista’s guidebook when I discovered that the OS has a unique way of handling Alzheimer’s. A lot of RAM was still left in my PC after all. What happened was Vista just placed the unused memory space in a cache labeled as SuperFetch.

SuperFetch allocates memory space to programs or processes as they need them. This ensures that each kilobyte is used to its fullest. This is definitely better than leaving memory to rot in idleness.

So the next time you check on your RAM meter, don’t be surprised if you see that you only have a few megabytes left to burn even if you’re not running any program at all. But this doesn’t mean that you can be complacent when your system slows down. Don’t just blame it on the possibility that SuperFetch might be conking out on you. Consider every possible problem. Who knows, your PC’s slowdown might really be caused by a bad memory module.
