Every generation of Microsoft operations systems increases the demands on your computer’s hardware. A computer than can run Windows XP just fine may struggle under Vista. It is almost certain you’ll need to add Compaq RAM memory before upgrading your operating system.
Vista’s Memory Requirements
If you want to install Vista on your Compaq, Microsoft recommends at least 512 MB of Compaq RAM memory to run Vista Home Basic and 1 GB for Home Premium, Business or Ultimate. However anyone who knows much about PCs knows that suggested requirements are fairly laughable. Yes you could get Vista running on this amount of memory and it will work fine, as long as you don’t run any other software. Fire up your word processor or your checkbook program and suddenly the system slows to a crawl. If you enjoy games, good luck trying to get a computer game to run with that amount of memory!
A general rule of thumb is to at least double the memory required and that means a Compaq memory upgrade of 1 GB for Basic and 2 GB for the other versions. More is better, so don’t be afraid to max out your computer’s memory capacity. You will be surprised how much faster things run when you do.
The Limits of 32-bit Vista
Your Compaq RAM memory is broken out into many, many tiny pieces of information. If you have 1 GB of memory, you have just over one billion compartments that the computer can fill with data. However, to find that information the computer needs the address of the right compartment. Without getting into the tedious subject of binary math, a 32-bit operating system like XP can address up to 4 GB of memory. More than that and the operating can’t use it because it can’t create a number big enough to read or write data there.
However a 32-bit operating system addresses 4 GB of memory only theoretically. Many addresses are reserved by the computer hardware so can’t be used by Windows or by other software you run. That means that realistically a 32-bit operating system can access only about 3.5 GB of memory. While that’s adequate for now, will it be adequate in the future?
64-bit Vista Breaks the Barrier
Users who want to install truly huge amounts of Compaq RAM memory can choose a 64-bit version of Vista instead of a 32-bit version. These have much higher memory limits. 64-bit Vista Home can fully support up to 8 GB of memory, Home Premium 16 GB and other versions 128 GB or more!
Most versions of Vista, particularly the ones pre-installed on off the shelf computers such as Compaq, are 32-bit. Buyers must explicitly ask for the 64-bit version. When you do so, the sky’s the limit on your Compaq memory upgrades. Lots of memory translates to terrific performance, so don’t let your system be handicapped by 32-bit Vista.
