I currently have 64mb sdram. I want to upgrade it. When i put in a larger size ram
the computer will not boot.
I tried every configuration of leaving in and taking out the old ram, moving the ram to different slots
but as soon as the new ram is installed the machine will not boot.
Configration is
450mhz pentium 111
440BX chipset
512 L2 cache
Phoenix bios
80gb Hard drive

    What type of DIMM do you want to add?

    1. Many old BX motherboards don't support more than 128 MB in one slot.
    In case you are trying to add 256MB SDRAM Dimm - this could be your problem.

    2. Another issue could be Ram speed - SDRAM can be of 3 types: (the speed is written on the DIMM - memory board itself ( a sticker))

    66 Mhz
    100 Mhz
    133 Mhz

    In case you are putting different types - they may not work together

    by:woodendude   download and install Everest , under Motherboard, SPD it will tell you exactly what type of memory you currently have in your system, then purchase the same. You're having a compatability problem.

    Why should there be a compatibility issue if the only ram inserted is the new ram. The old was removed. The speed and type of ram is the same. Only the size is different.

    If that the case then as said above by  muhalok  there is a great possibility that your system won't support the new stick.
