    Hi guys

    which type of Ram is Apple using in the '09 Mac Pro?
    I ordered mine with 12GB, but I would like to add two 4GB sticks because the prices are pretty low at the moment.

    Do I have to use ECC or registered Ram, or just standard 1066MHz sticks?
    My modules are from Hynix.

    DDR3 PC3-8500 • CL=7 • Unbuffered • ECC • DDR3-1066 • 1.5V • 512Meg x 72

    ^ Those are the specs so yes, it must have ECC and it has to be unbuffered.

    non-ECC unbuffered memory will work too as will slower and faster speeds with faster memory clocking down to 1066MHz.

    Thank you guys, I almost bought the wrong modules. :eek:

    Damn it.
    The unbuffered modules are about 300-400 Pounds, the registered ones only a hundred.
    So I guess I won't be upgrading till the unbuffered are about a hundred quid.

    You can order from OWC for $165 for a 4GB DIMM. Works out at just under £120 (inc. VAT) each plus shipping. However there was an issue in mixing 4GB and 2GB DIMMs early on that still might be present, you'd have to speak with them. Registered memory should work too, but you can't mix those with unbuffered.

    That are 2GB modules. I already have 6 of those in my Mac, that's why I am looking for 4GB modules.


    That's a pretty nice price compared to those here in Europe.
    I hope OWC can confirm that the modules work together with my 2GB sticks.
    Thank you very much!

    Definitely an option when I'm back in germany, even though I'm highly sceptical towards the 10 year warranty as Hynix themselves give only one year. ;)
    Great offer though, I will definitely keep that one in mind.
