    My computer has a 128MB memory and wanted to add a new slot of memory 512MB the computer does not recognize both memories 128+512=640MB when I boot up. It only recognises the 512MB. I swap the slots’ positions and only the 512MB is recognised. Then I do all the combinations for all 3 memory banks and the Pc still only recognises the 512MB. I take the 512 out and leave the 128 on. The PC immediately recognises the 128. I then take the 128 out and put the 512 back in only. It is immediately recognisable. When I put both slots of memory 128+512Mb back in, the PC detects the 512MB only. Could you please help?

    Many thanks:confused:

    Sounds like a compatibility issue, it would help a bunch if you told us the make/model of the motherboard and/or computer.

    Maybe your PC only supports a maximum of 512 MB. What is the make and model of the computer?
