I thought that was normal. Happens to me all the time. Sometimes with memory and somtimes with the speed of my processor. I ran a few test and realized that it's not that you're only using the amount they say you have but it's because that's how much you currently have left i.e. my processor is 2.2 GHz but when i check the specs it varies depending on how busy my processor is.

This is both a BIOS and a Windows issue.

Many BIOSes limit the amount of available memory because Windows XP has great difficulty in working with more than 3.5Gb of the stuff due to the way its been made.

XP 64-bit and the upcoming Windows Vista (and Windows Server 2003) completely do away with this issue and will up the limit to something well past the 10Gb mark, which should futureproof us all for a few more years :whistling:
