I think you might be confusing what I said. I said it was possible to put up to 128 Gig of RAM in the 2010-2012 Mac Pro. I did not say it was possible to put this much RAM in the new Mac Pro which has not yet been released. Its limit is 64 Gig.
Ok , I copy you. I believe that I misunderstood Jim Kasson. When he say :
"The 64 GB makes it a nonstarter for me. Is that a hard limit, or just an Apple-imposed limit? IOW, can OWC fix that?"
I understood that he was talking about the new machine, that also have a 64GB limit.
So when I read your reply " that it is a hard limit", I continued with the misunderstanding.
So we all agree that we don't know if the new Mac Pro will be able to get more than 64GB with denser memory modules.
Thanks for the clarification.
For photography 64GB is more than enough, but for video, 3D and engineering and heavy multitasking folks could find it limiting.
For me the issue with the machine is more about price, the lack of nvidia options for Adobe software (cuda) and the storage. I don't like that we can't expand without trowing the old module and I have concerns about the form factor. The PCIe connector is not were it normally is on PCIe based SSDs.
The same interface placement issue runs for the graphics cads. If that was not the case it will be easy for Nvidia and AMD to keep the machine actualized.
This is particularly painful because, the mac market is finally big enough for that to happen. We were finally seen new cards from the top vendors target at the mac market.
A normal box will have keep the momentum. I sense that this is a missing opportunity. In the other hand if Apple got a good contract from AMD and keeps the cards current and a good price, it will change my perspective.
Finally I am not sure about the price performance of the 6 core, and for me the 4 core is not enough difference from a top of the line iMAC with a good Nec monitor. For 1000$ we get more powerful graphics and a chip that cost less than 600 dollars.
