    Hi

    Going to be installing RAM into a Toshiba Satellite A55 series notebook. According to Crucial.com (where I scanned to see whats in there/etc)

    http://www.crucial.com/systemscanner/viewscanbyid.aspx?id=F010ED6831D926C3

    It says there's already one stick of 512mb DDR PC2-5200 RAM. It also says it can take DDR PC2700 RAM.

    Is there a difference between DDR PC2-5200 and DDR PC2700? If so, what? Can I mix the two types?

    Thanks, in advance, for any replies!

    Cheers,

    FOJO

    No, those are two memory types. They're not electrically or physically compatible.

    Exactly...that crucial memory scan output is a bit strange. Usually crucial list PC2 as DDR2. The memory scanner probably got confused because apparently there is a satellite A55 that uses DDR memory and one that uses DDR2.

    Fojo you will need to confirm which memory type your satellite uses, you can use CPU-Z to confirm what type of DDR memory you have.

    I was confused about Crucial's results since they listed both DDR & DDR2 memory for the Satellite. I'll try CPU-Z and see what it says, then post back.

    Dont go by crucial's scanner. It has been wrong for me several times. :rolleyes:

    Just open up the laptop, and look at the memoery yourself. That is the only way you can be sure. ;)
