    128mb ram read as 64mb?????????????????

    I have an old mobo, it only supports dimm ram max 128mb each slot, with three slots total. I have in bank one a 128mb chip, in bank two a generic 32mb, and in bank three a new 128mb chip.

    I install the new chip and for some reason the pc reads it as a 64mb ram chip instead of 128mb chip.

    I'm gonna experiment with the placement of the chips ie, their order on the banks. Is there a reason for the chip read at only half it's 128mb?

    Here is Sandra Diagnostic:

    SiSoftware Sandra

    Logical/Chipset Memory Banks
    Bank 0 Setting : 128MB SDRAM 7-1-1-1R 4-1-1-1W 3-3-3CL
    Bank 2 Setting : 16MB SDRAM 7-1-1-1R 4-1-1-1W 3-3-3CL
    Bank 3 Setting : 16MB SDRAM 7-1-1-1R 4-1-1-1W 3-3-3CL
    Bank 4 Setting : 64MB SDRAM 7-1-1-1R 4-1-1-1W 3-3-3CL
    Speed : 1x 100MHz (100MHz data rate)
    Multiplier : 1/1x
    Power Down Mode : No
    Fixed Hole Present : No

    Memory Modules
    Memory Module 1 : JA 00FFFFFF 128MB 8x(16Mx8) SDRAM PC133U-333-542 (CL3 upto 133MHz) (CL2 upto 100MHz)
    Memory Module 3 : Kingston 6MX64PC133CL3 168P 151EC901 128MB 4x(16Mx16) SDRAM PC133U-333-542 (CL3 upto 133MHz) (CL2 upto 100MHz)

    as you can see here:
    Logical/Chipset Memory Banks
    Bank 0 Setting : 128MB SDRAM 7-1-1-1R 4-1-1-1W 3-3-3CL
    Bank 2 Setting : 16MB SDRAM 7-1-1-1R 4-1-1-1W 3-3-3CL
    Bank 3 Setting : 16MB SDRAM 7-1-1-1R 4-1-1-1W 3-3-3CL
    Bank 4 Setting : 64MB SDRAM 7-1-1-1R 4-1-1-1W 3-3-3CL

    the diagnostic insists that i have 4 memory banks and 4 chips, the two 16mb is actually only one 32mb, I'm guessing cause of it's old and most likely a piece of crap.

    Any Ideas?

    I tried just the new Kingston Ram and it gave the 64mb reading in any slot with or without the other ram chips.

    just found out the reason:
    puke:
    Problem: I've updated the BIOS and the system still only sees 64MB of additional RAM.
    Solution: The module's chip density may exceed the capabilities of the system's chip set. The high-density memory module may only have chips on one side of the PCB (Printed Circuit Board). Resolving this density problem may be possible by contacting Kingston's Technical Support department at 1-800-435-0640 (within the U.S. and Canada) or (714) 435-2639 for a product recommendation that will better meet your system's compatibility requirements.

    I knew my mobo wouldn't take high density ram chips, didnt say anything on the box.

    :rolleyes:

    ^^^^

    yepper - u got your single sided and double sided memory - i think alot of people over look this when they buy memory - u figure pc133 or whatever is pc133 and does not have variations on it,

    i made this mistake myself once.

    not all high density dimm ram chips are single sided, I have another single sided that is not high density. It is better to 'count' the number of individual chips on the ram chips, I have now learned. My aforementioned regular single sided chip had 6 smaller chips on it's one side. The high density ram had only 4 smaller chips on it's one side.

    Keep you receipts!!!
