    RAM

    I recently upgraded my PC's RAM from 2GB to 4GB. I did some research and found that my PC did indeed support 4GB. I purchased the correct RAM and installed it, my PC now sees 3.25GB. The problem is now that my puter runs slower now then when it just had 2GB in? I've mucked about with the page file but to no avail.

    Any other ideas?

    If you are running a 32Bit operating system it can only see 3 gigs of ram plus whatever ram your video card has. So since it is seeing 3.25 Gig's of Ram I would assume you have a video card with 256 mb of RAM on board.

    But the bottom line is a 32 Bit OS will only support 3 gigs of RAM.

    I just found out about that myself a few months ago after I did an upgrade on my PC.

    ...and you just saved me some grief. I didn't know that, either. Thanks.

    Last night, I shot an elephant in my pajamas. How he got in my pajamas, I'll never know.
    love, piaqt

    Hello Bubba, in what way does you PC run slower ?

    Maybe when you added the extra ram the bios re-set the ram (or CPU) to a slower default speed ?

    List your system spec's and what OS. Run CPU-Z and post the results.

    If you are running a 32Bit operating system it can only see 3 gigs of ram
    Thats in MS Windows, Linux supports up to 64gig
