Ok, so I have an old Dell Dimension C300. It originally came with 128mb of RAM. I purchased 512mb x2, and made sure that it was "PC133U-333-542", and 133mhz - Just like the 128mb module that came with it. I installed the new RAM, and the computer turns on, but it says I only have 128mb of RAM still? Any help on this would be great
