    I'm looking at memory for a Thinkpad R40:

    * 64-bit Double Data Rate (DDR) non-parity SDRAM memory
    * PC2100 at 266MHz
    * Two 200 pin SO-DIMM memory slots, one slot is pre-populated with 128MB or 256MB, leaving one socket available
    * Pentium 4, Celeron models
    o Supports up to two 512MB SDRAM SO DIMMs
    o Supports maximum memory up to 1.0GB
    * Pentium M models:
    o Supports up to two 1GB SDRAM SO DIMMs
    o Supports maximum memory up to 2.0GB


    At Edge I found some memory for this:

    The problem is what is the difference between SODIMM and one called S.O. DIMM? On IBM's site they write it as SO-DIMM.

    My understanding here is this is all the same, just different ways people are writing it?

    But if that is so why then does Edge list them two ways in the links below?

    Yeah now I realize there is only one word, sodimm, they're the same.

    One is just listed with a IBM support is all for compatibility.

    THANKS
