    Hi there

    I thought it a good idea to increase my RAM. I bought a 1 Gb 400 mhz card. I Took out the two 256 mB cards and inserted the 1 Gb card. The computer recognised it and said 1 Gb when I called up System Properties. So far so good.

    I powered down, and inserted one of the 256 mB cards. Why not go for 1.25 Gb I thought to myself. After booting up, the computer was noticibly slower. I Changed the 256 card for the other 256 - same result.

    I am aware that the cards must be the same speed - and they are. They are all 400 Mhz (the best my motherboard can handle!)

    I use a Pentium 4 2.4 gig and Windows XP home with SP2.

    Can anyone explain this anomoly to me please?

    It's more complex than simply having modules of the same speed, you need to add factors such as manufacturer, chip type, density et al. The most common issues with compatibility issues is differing manufacturers and chips, this is probably the issue you are experiencing.

    And with that, I'd just leave the 1GB stick in with nothing else and call it a day.

    eBay anyone?
