    I am getting this RAM shortly http://www.crucial.com/uk/store/mpartspecs.aspx?mtbpoid=AD50DB81A5CA7304


    At the moment my pc had 1GB dimm installed when really it should be matched pairs.

    If I install the 2 new dimms I am getting will there be problems as the latency is different on the 2 new dimms than the one I have installed.

    The one I have is 5-5-5-12 the new ones are 4-4-4-12 am I likley to get BSODS?

    I think there shouldn't be a blue screen, but there is a slight possibility that due to an incompatibility issues you might see a BSOD. With that said, usually what will happen is that the newer faster memory would run at the lower speeds of the other memory. The bios would adjust the timings on the memory to be synchronized with the other memory.

    Cheers for that :)

    Do you think I should just remove the old RAM?

    you'll be fine, the latency just refers to access times and wait times of the memory where lower the numbers are better. its no different from using different speed memory, the memory will just run at the max its rated for.

    read :)

    no, stick the faster memory in the first paired dimms so its accessed first.

    Cheers grim, so I stick the fastest dimms in the first slots then then my original after that?

    Just downloaded the crucial system scanner and it has recommended different RAM aswell as the one I have chosen, the one I chose is whats in my motherboard book.

    The ram chosen by the crucial scanner is the same latency as the dimm I already have, the ram I chose and whats in the mobo manual is dfferent.

    But if this will cause no problems then I will get the ram according to the mobo manual.

    Grim is correct. It should work fine.

    I believe he is, I just thought it was weird how the Crucial scanner recommends a different type that isn't ene in my mobo manual.
