Crucial.com Memory Configuration Scanner

The Crucial.com Memory Configuration Scanner is a bit of an odd duck to categorize. It is a web application. However, since it is ActiveX based, it only work on Windows in Internet Explorer. It scanns your PC's memory configuration and tells you how much memory is installed and what the slot configuration is. It is not, however, 100% accurate. The image above is the result of scanning my old XP PC which blew out a DIMM the other day. It shows one slot filled with 512MB RAM and three empty DIMM slots. However, the system actually only has two slots. I suspect, the ActiveX control may be reading the Nvidia AGP video card as system RAM.

In any case, the Crucial Memory Advisor Tool web form option next to the ActiveX memory scanner has a great database that appears 100% accurate (at least for the systems I threw at it). So, if you need to replace RAM like I do right now, make sure to check the ActiveX memory scanner against Crucial's web database query tool to make sure you get an accurate PC memory configuration.
