    computer sees 64MB not 128MB (celeron,gigabyte GA-7WMM6)

    Can somebody help me here or refer me to an appropriate forum.
    I'm trying to install a 128MB pc133 sdram memory card on my intel celeron, that did have two 64MB. The computer runs windows but only sees 64MB after the 128 is installed and behaves as if there is only 64MB.
    It seems to think the 128MB is a 64MB
    The 128MB is the same type as the two 64MB, pc 133 cl=3 microchips on one side, 168pin
    The motherboard is a gigabyte GA-6WMM7 (not 7WMM6, mistake in title.)
    The memory test by Crucial, says the motherboard can take two 256MB, does that mean it's a software issue?
    I phoned a pcworld help line and the only thing they suggested was buying another 128MB card and install 2 at once.But i'm cautious of doing this as the comp' worked with one 64 installed and also with both 64MB installed, so why is it not working with one 128 installed.
    I've also tried a single 256MB (same specifications) and the computer screens didn't come on and the hardrive sounded like it wasn't loading windows.
    Any Suggestions?

    what happens if you put the ram in a different DIMM?

    what do you see at the 'POST' screen when you turn the computer on within the bios?

    what happens if you put 1x64 and 1x128 sticks in there?

    I worked on an old Compaq PC which had a gigabyte mobo with SDRAM PC133 a while back and had the same issue. I think the problem is compatability with the RAM you're using. Perhaps you'll need to try and get single sided RAM?

    PS. I never did find the fix.

    The same thing happens regardless of which DIMM i put the memory in.
    With one 64MB the comp loads as normal allthough very slow(windows XP)
    with a single 128 installed (either DIMM) it also loads but very slow, when i checkled the system settings under control panel, it says there is 64 when it should say there is 128.
    When i put two 64MB in, it loads much faster and runs smoothly, so i know how the comp' should behave with 128.
    The motherboard has only two memory sockets.

    These rams i'm using have chips on one side, the 64's work, individually and together, but the 128 behaves like i single 64, if i put a 128 and a 64 together(either way) it thinks there is only 64 and behaves as such.

    I think it may be an issue with higher density ram than the PC can deal with, not sure though

    replying to @scrandman, did you try two equal memory cards and it stilll didn't work, if so then it may be not worth my while buying another memory card, as PCWorld suggested?

    i have got the same motherboard that i use on a spare pc and i have got 2 sticks of 128's and it runs fine!

    one of the sticks is double sided and i know for a fact that it runs fine with just one stick of 128 in!

    so i really dont know what could be wrong with yours maybe faulty ram?

    ok, thats good to know, PCworld's advice may be wrong.
    Also, on my motherboard, there is no jumper connectors soldered to the board, having no jumpers just so happens to be the setting for pc133, which is what i have, but my BIOS options are somewhat limited compared to what the manual for this motherboard suggest i could adjust. There seems to be no options for memory BIOS adjustments on my particular computer. Is there a way to reveal these?

    @leeglf, does it work with one double sided 128?
    Also, does it also work with one single sided 128?

    That certainly could be the case

    I've had the same issue on one of my own systems in the past.

    (However, I'm not a techy - so I'm probably wrong )
