RAM Upgrade

I upgrade my machine from 512MB to add an extra 1GB but Windows only uses and detects 1.25GB which means one of my 256MB sticks aren't being used.

A friend suggests that maybe it has something to do with single and doudle sided RAm and the support for each with Motherboards. Maybe the Mobo only utilises a certain combination of each.

I'll try to fix it (if possible) and update on it.
