    Hello again!

    I've two ddr2 memory modules but they are different...

    First one is Hynix 512mb 1rx8 pc2-4200E-44-12
    Second is 512mb 1rx8 pc2-5300f-555-11-a0 ddr2 667 cl5 ecc

    But they are different and don't fit in the same socket...

    Any ideas ??? :)

    Can you post the specs of your motherboard, or a link to the motherboard on the manufacturer's website?

    Possibly one is registered memory, and the other is unbuffered.

    Post the actual part numbers and I'll look it up. For a Hynix module the number will start with HY.

    This is an unbuffered ECC module.

    Micron made this one. It is fully-buffered, which is why the key is in a different position. It is also ECC.
