Everybody has one, an old computer, maybe even an old server, that they have no idea what kind of memory it takes, how much it can hold, or how much it would cost to upgrade the beast. Sure you could lookup motherboard, and memory module part numbers and find out yourself. But now there's an easier way:
The Crucial System Scanner automatically detects your computer's information and gives you the details you need to purchase a compatible upgrade. To run the Crucial System Scanner, you need Microsoft Windows 95 or higher.
