Question:

How much RAM memory should I have for Windows Vista?

Answer:

At least 2GB is the short answer. Some systems were sold with only 1GB of memory when Vista first hit the shelves. That is barely enough to run Vista let alone your Anti-virus/ Anti-Spyware, on-board video, and all your applications. If your new system is running slow you probably need more RAM. The most common version of Vista is a 32 bit version. That version will support up to 4GB of RAM.

The following table specifies the limits on physical memory for Windows Vista.

Enterprise - 4 GB 128 GB
