    I have a Notebook 2200t that has (2)256MB PC133 installed.

    The system is only recognizing 192MB.

    No matter how I configure the (2)256MB modules (ie using only 1-256 chip, swapping the 1 chip to either bank etc...), the system only shows 192MB

    Why won't this system show/see the whole 512MB ram ?????

    BTW, laptop is running XP Pro.


    TIA

    My guess is that 64MB goes to the video memory . Which means only 256MB are missing , maybe a bad slot ?

    I'd check what the bios reads and go from there .

    Use CPU-Z as a 2nd check. What is your computer that could help.

    Edit: sorry I see your computer I missed I will look. No I am not sorry who makes it? When I Google I get Navigation systems.

    Ok....Checked out a few more things and here's what I've come up with.

    CPU-Z is a great little program! :)

    #1) Yes, the Ram was being shared with the Video (via the BIOS). I changed it down to 8MB shared and the Ram went up to 248MB. That was cool. :cool:

    #2) I had a couple of sticks of 128MB PC that I worked every conceivable configuration between them and the (2) 256MB sticks. Best I could come up with was 376MB total Ram.

    No matter what configuration I tried, I could NOT get the (2) 256MB sticks to play nice together and obtain the rated 512MB. :rolleyes:

    The brand actually IS NOTEBOOK. Shows it right on the front cover. It is made by CLEVO.

    Check it out here-->> http://www.clevo.com.tw/products/2200t.asp :cool:

    So all 4 rams (2x256 and 2x128) work fine, and both slots work correct?

    Do you have the latest bios?

    In CPU-Z click the "SPD" tab, you can check what is in both slots. Are they reporting correct? I am suggesting this to rule out or identfy a bad stick.

    Yes, to all the above.

    I'm not able to locate documentation as far as the limit of Ram on this laptop. :(

    I did find a write up in a Ram check program that shows NOT all Ram reporting programs show the actual installed Ram. This does lead to confusion for sure! I've downloaded and tried a few and they are correct. I got conflicting information !!

    That said, I believe it's most likely an incompatible stick of 256MB PC133 I have here. :rolleyes:
