    I've just switched from PC to Mac by buying an end of lease Mac Pro from work. Now whilst i'm confident enough to physically upgrade the RAM myself, i'm a bit clueless when it comes to which type of RAM to install.

    This is a 1st gen 2006 Mac Pro (MacPro1,1). There is 4GB (2x2GB) of RAM already inside, which is made by Crucial (so I assume it has already been upgraded once in its life).

    However, when I search crucial.com for another 4GB for my system, it suggests a different type of RAM, so i'm wondering whether it would be better to get more of the older RAM, or simply buy the newer one and install it with the older one.

    And i'd also appreciate if anyone could tell me what the difference is between the two!

    Older, current Crucial RAM:

    Newer RAM suggested by Crucial:

    The Crucial ram is DDR2 667 Mhz
    The Amazon ram is DDR2 800 Mhz

    I believe the Mac pro 1.1 uses 667 mhz -so you are not getting any benifit from using 800mhz ram

    I work for an IT company called Mr Memory and i will be able to supply the memory you need cheaper than crucial will be able to supply. Just send me an email to sales@mrmemory.co.uk and i will be able to assist.

    The memory you need is the DDR2 800MHz memory. The 667MHz memory is now no longer widely available and the 800MHz memory will simply clock down to the 667MHz speed.

    The memory we supply is liable to be hynix and comes with a full lifetime warranty.

    Thanks, Atomic101. Seems to be echoed here too. But as MacSpecialist has said, the 800Mhz will be clocked down, so it just goes down to cost really.

    And MacSpecialist - thanks - i'll be in touch! :)
