Is this RAM compatible?

The Kingston site says this:

but I’m wondering if this will work.

They’re both DDR2 533 pc2 4200

What are you talking about?

The first link is what the Kingston sites says I need for a Dell Dimension 4700. I cannot readily find that so, I’m wondering if the Ram in the second link would work.

should be fine so long as they’re the same type of ram, however if you want I am sure cdw.com has those kingston chips

Yeah it should be fine
