Ok computer folks...RAM question

I just set up an old desktop. I put two 512MB sticks of RAM in the slots. One of them is showing up as 5GB!

In Googling this I found the usual problem of a given amount of installed RAM showing as less. This one really is weird!

The computer is running well, updating wonderfully, no performance problems.

Any ideas?

Thanks!:)

Are you sure they are both 512mb boards? I'd run a diagnostic just to check the RAM is all functioning correctly, just in case.

They are DDR PC2700 sticks. I don't think a 4GB stick exists in that line!

I'm not sure what sort of diagnostic to run for RAM. I'll try reseating it and see what happens.

Thanks! :)
