I have bought an old Dell PC (well know auction site) and it is fine for what I want. It only has 1.5GB Ram on a 32bit Windows XP, I want to put the maximum it will take (4GB) but I'm confused as some modules with the same spec are advertised as being for AMD and won't work with an Intel PC. Is there a difference?.

"It only has 1.5GB Ram............I want to put the maximum it will take (4GB)"
1.5GB is usually more than enough for most XP users. If that PC isn't using more than that then you'll be wasting your time and money with a RAM upgrade. Thankfully it's easy to find the information required to make that decision:
After you've been using the PC for a while with all the programs you'd normally have running, open up XP's Task Manager and click on the "Performance" tab. Look at the value for "Commit charge (K) -> Peak". That shows the maximum amount of memory (including page file usage) that's been used for the current Windows session. If that value is equal to 1.5GB or greater then get some more RAM - if it's a lot lower then extra RAM won't make any difference.
A quicker way is to simply glance at the "PF Usage" graph to see if it ever shows more than 1.5GB.
By the way, there's no such thing as "Intel & AMD memory" - it's all the same.
