    Hi guys,

    first of all, I have looked through some threads and have found some stuff about upgrading the existing mid 2010 quad MP's with hex cores later.

    Could someone just confirm the following before I splash out and go for the base config mid 2010, ie 2.8 GHz quad or the 2.66 GHz '09 model (refurb):

    1) The mid 2010 can be upgraded to hex by simply dropping the new CPU and adding 1333 capable RAM?
    2) The mid 2009 can be upgraded the same way?

    Thanks,
    oi

    1. Yes. All 2010 Mac Pros ship with 1333MHz memory by the way.
    2. No. Forget about upgrading a 2009 model to 6-core processors, not worth it.

    Why?
    According to www.macsales.com it is possible.

    Their statement is a little misleading, but no, it is definitely not possible.
    The 2009 models EFI does not support the new processors. If you want a hex in your 2009 machine you'd have to replace the logic board, which is not really cost effective.

    2010 28 quad it is. Thanks guys!

    Hopefully I can pick one up at a good price tomorrow. I have already got my 12GB of RAM from OWC. (1333)

    Cheers,
    oi

    Definitely the backplane which holds the EFI ROM, I'm not sure about the daughterboard, though.

    There is a topic about a user called roman23 around here who did this conversion, and I recall that he replaced both boards.

    Can a X5667 B0 stepping be installed on a 2009?

    No, it uses the same B1 stepping as other six cores and the EFI in 2009 Mac Pro does not support that stepping.

    Only CPUs with D0 stepping work.

    So just an update, got base config 2010 MP at 10% (Aussie BlackFriday version).

    I am contemplating becoming sick and having to leave work early :)

    Got my 12GB of RAM of OWC and a 300GB Raptor Boot Drive. Should be nice and fast.
