CPU upgrade question

  1. Hello, I was recently given a Dell Dimension 2400 from a friend. It had absolutely no upgrades, however I had old parts sitting around and I gave it a bit of an upgrade. I put in 4gb of ram (however found out it had only supported up to 2gb, so I had to remove a card) and added a Visiontek Radeon 9200 graphics card in. Now, I have two processors here that look like the might fit, but I wasn't sure. So, I was hoping to get a second opinion from someone who has a bit more experience with this than I do. I have two spare processors

    one of them is a Pentium 4 3.00Ghz (

    the other is a Pentium 4 1.6Ghz (

    Would either of them work? Also, would upgrading to windows 7/vista increase the support for ram? Thank you.

    Socket details:
    • Pentium 4 3.00Ghz is LGA775
    • Pentium 4 1.6Ghz is PPGA478
    That is two different architectures.

    Specs for Dell Dimension 2400
    Please note this would be PPGA478 architecture not LGA775.

    What CPU is currently in the computer?

    I believe the default cpu is in the pc at the moment. I didn't want to risk putting in any of those cpu's in case it would ruin the computer. Thank you so much for your quick and detailed response!

    Moderator note: Tprior87, FYI, when responding to the last post in the thread, it isn't necessary to quote the whole thing. Sometimes if the post is long and you are responding to a certain portion of it, you may quote the relevant portion. One consequence is if the quoted text contains a link (as in this case), our forum software moderates new member's posts (holds it invisible) automatically until a moderator or administrator comes along to review it and make it visible. It's an anti-spam measure. From your perspective that only serves to delay your post and any subsequent answers.
