    Hallo community, so now where we know, that the mac pro will support 4GB-Dimms and can be pushed up to 16 GBs of Ram, i ask myself if the Mac Pro (Quad and/or Octacore) will support 8GB - modules of DDR2 ram or even 16GB - modules.

    Is there any chance, that the Mac Pro Nehalem Quad will support 8 GB Dimms and can be pushed up to a total of 32 GB of RAM?

    It will be able to support 1TB sticks. So yeah it can support 4TB's of RAM.

    Well right now it is cheaper to buy an 8 core and use twice as many smaller DIMMs for such amounts. 8GB and 16GB DIMMs probably won't drop heavily in price either in the short term where as 4GB will. That is assuming the Mac Pro can even be used with registered memory (should, but it's Apple).

    Well now i already have my quad ordered and shipped and wil lnot buy me an octa,
    but well, in 2, 3 or 4 years, what are then the prizes of 8 GB - dimms?

    and what are the chances that this would work with the quad nehalem mac pro?
    i mean, what is the usual situation for apple?

    Not in this revision, anyway. Intel's 64-bit architecture only uses about 40 the 64 bits for the physical address space so the physical address space is limited to around 1TB.

    O' what a shame. I was really looking forward to having 8TB of RAM.

    Until someone tests it and says it works we won't really know. There is no technical reason why they won't work to my knowledge. Memory goes very low in price until it is replaced then it comes up a lot. Just a case of buying it if you can afford it and you need more memory really.

    what can be expected meaning the prices of 8GB dimms when they are cheap. And what are they now?

    The controller supports up to 192GB of ram.

    Therefore, a Quad can support 192GB/2 = 96GB of ram. But because of the 4 ram slots, its limited to 64GB of ram. DDR3 supports up to 16GB modules.

    It just depends on how much you can afford and whats available.

    Don't expect anywhere near affordable 8GB modules until a few months after the next Mac Pro comes out.

    Crucial wants $1380 for an 8GB DDR3 PC3-8500 memory module. I imagine they'll come down in price over time, but I misplaced my crystal ball recently and for the life of me I don't know where it is.
